00:00:00.399 --> 00:00:07.519
you've seen a portable projector you've seen a CRT but have you seen a portable

00:00:06.000 --> 00:00:15.480
CRT projector okay portable might be a

00:00:11.719 --> 00:00:18.920
little generous but the vidam magic fp60

00:00:15.480 --> 00:00:21.480
from Sony came with its own carrying bag

00:00:18.920 --> 00:00:28.359
has a microphone input for projecting your voice and did I mention there's a

00:00:23.760 --> 00:00:30.560
built betamax player no how about the

00:00:28.359 --> 00:00:36.160
fact that it uses a single tube to produce a color image rather than three

00:00:33.399 --> 00:00:40.879
tubes like most other CRT projectors in this episode of lonus

00:00:38.920 --> 00:00:45.520
overpays for ancient Hardware that you've probably never heard of we'll be

00:00:43.200 --> 00:00:50.360
cosplaying as a traveling salesman from the 1980s I can't wait to play with this

00:00:48.520 --> 00:00:55.399
thing just like I can't wait to tell you about our sponsor build Redux sometimes

00:00:53.359 --> 00:01:00.440
computers are hard but all the time build Redux is easy they'll get a custom

00:00:57.840 --> 00:01:04.680
PC built and delivered Direct ly to your doorstep just check them out at the link

00:01:02.239 --> 00:01:10.159
down below according to radiomuseum.org the introductory price for the viam

00:01:07.240 --> 00:01:13.200
magic fp60 was $3,000 that's not that bad for a

00:01:12.200 --> 00:01:17.960
portable projector except that was in 1984

00:01:16.159 --> 00:01:22.759
meaning it would be closer to $9,000 today that's high enough that

00:01:20.640 --> 00:01:28.200
just about nobody was going to be buying these for home theater use but

00:01:25.560 --> 00:01:34.119
businesses well that's another story and cosmetics giant Avon even went as far as

00:01:30.759 --> 00:01:35.880
to co-brand the fp60 and deploy it to

00:01:34.119 --> 00:01:43.720
company Representatives across the United States hence my uh world's

00:01:38.960 --> 00:01:46.600
largest makeup bag here at 35 lbs she's

00:01:43.720 --> 00:01:51.040
more luggable than really portable but when you compare it to other mid 80s

00:01:48.880 --> 00:01:57.960
options for boardroom presentations for example like what a CRT on an AV cart or

00:01:54.840 --> 00:02:00.719
a real toore projector the fp60 had

00:01:57.960 --> 00:02:04.000
major advantages in terms of screen size and in terms of durability and

00:02:02.240 --> 00:02:08.479
convenience so we're going to get to that whole presentation use case but

00:02:05.680 --> 00:02:12.959
first I have a burning question kenet game oh

00:02:10.239 --> 00:02:17.760
yeah fun fact by the way the NES wouldn't come out in America for another

00:02:15.040 --> 00:02:21.599
year we just felt like being Gamers it would be a great choice for us to

00:02:19.200 --> 00:02:28.360
evaluate the latency not going to lie brother I can see it's on but

00:02:24.280 --> 00:02:30.360
uh wow barely I mean is that supposed to

00:02:28.360 --> 00:02:35.360
be curtains at the top or is that just this reason everyone had blacked

00:02:32.560 --> 00:02:40.879
out media rooms right okay we're going to have to lose some lights yeah get the

00:02:37.959 --> 00:02:46.920
lamp there we go oh my God yeah the lamp doesn't do much no we need that one hold

00:02:43.319 --> 00:02:49.000
on I got you I got you it's still

00:02:46.920 --> 00:02:54.319
horrible get this okay hold on I got this one I got this one what that's the

00:02:52.440 --> 00:03:00.480
only light we have left and that's all we got turn it off dude this is terrible

00:02:57.879 --> 00:03:03.599
well you know it's a crd yeah but it didn't get very bright to begin with

00:03:01.879 --> 00:03:07.599
okay hold on hold on that's that's markedly better okay

00:03:06.440 --> 00:03:14.760
we're getting somewhere I mean that's about as far as we're going to get but that's that's not bad okay that lamp's

00:03:12.239 --> 00:03:22.040
got to go that lamp was throwing so much more light than the CRT

00:03:18.720 --> 00:03:24.040
projector with that said looking into

00:03:22.040 --> 00:03:30.319
this thing that's about the brightest CRT I've ever seen right that indextron

00:03:26.560 --> 00:03:31.720
wow there's like hairs in there oh yeah

00:03:30.319 --> 00:03:37.599
you can probably it'd probably be fun to try to play with the focus if you want to basically that's the cross oh it's

00:03:35.760 --> 00:03:42.760
probably slightly out of focus there's also a uh manual focus on the very front

00:03:40.879 --> 00:03:47.319
that you can use okay but you shouldn't don't touch them together or you can

00:03:44.519 --> 00:03:50.799
break the whole Focus system yeah it's definitely still got some blurry spots

00:03:49.319 --> 00:03:55.000
do you have any idea what that is no Elijah tried cleaning the lens so like

00:03:53.120 --> 00:03:58.640
it's been wiped down so basically Elijah touched it yeah Elijah tou said that it

00:03:57.079 --> 00:04:02.040
was bad before he touched it I'm not blaming him in this scenario

00:04:00.599 --> 00:04:05.879
maybe some of the phosphors are worn out or something or like some of the co CU

00:04:04.000 --> 00:04:14.239
you can see it looks like burnning when you've got it on a single um like color

00:04:09.480 --> 00:04:16.160
here oh my God what this is perfect

00:04:14.239 --> 00:04:23.320
right there's no latency there's none cuz it's a CRT it's a projector but it's

00:04:18.639 --> 00:04:26.040
a CRT a CRT wow it's like so easy this

00:04:23.320 --> 00:04:29.600
is like freaking Easy Street and it looks pretty good hey like those blacks

00:04:27.759 --> 00:04:36.440
actually look pretty black it's pretty colorful too like this is not bad no

00:04:32.919 --> 00:04:39.479
it's not bad at all I mean it's not good

00:04:36.440 --> 00:04:42.240
no but in a in a dark environment though

00:04:39.479 --> 00:04:42.240
this is like totally

00:04:46.000 --> 00:04:51.600
fine oh no wow you're diding so well

00:04:49.320 --> 00:04:55.639
let's see you do better I probably won't another thing that's not included with

00:04:53.240 --> 00:05:00.240
ours is a working speaker unfortunately yeah it's just not working and

00:04:58.000 --> 00:05:06.199
theoretically we could use our uh technical manual service manual to

00:05:02.240 --> 00:05:09.120
repair it or we could just not do that

00:05:06.199 --> 00:05:13.360
oh my God you're wasting the pow there's no pow we don't need it I thought you

00:05:11.759 --> 00:05:18.120
were too good you don't need the pow did you die yeah again I hit a blue shell

00:05:16.240 --> 00:05:24.160
while it was flipped over we've already realized that when it comes to old games

00:05:20.800 --> 00:05:26.880
you'll usually win new games I don't

00:05:24.160 --> 00:05:32.000
know okay well that was you dying on purpose I actually did not

00:05:30.039 --> 00:05:37.440
okay all right this is it for all the marbles here we

00:05:34.280 --> 00:05:40.080
go um they kill me yeah yeah yeah they

00:05:37.440 --> 00:05:44.520
kill you if they're um moving yeah yeah yeah this feels too good I know right

00:05:43.400 --> 00:05:48.280
like it feels like you're playing on a CRT yeah because the only additional

00:05:46.520 --> 00:05:55.319
latency compared to looking directly into a CRT is the speed of light to the

00:05:51.080 --> 00:05:57.880
screen that's it so just the slightly

00:05:55.319 --> 00:06:02.440
increased like distance the light has to travel like this is awesome

00:06:00.400 --> 00:06:06.520
but blue we're getting about 2.2 nits 2.2

00:06:03.720 --> 00:06:11.680
nits the point two matters let's stop it for now cuz I want

00:06:09.000 --> 00:06:16.479
to talk about brightness In fairness most projectors don't get that bright

00:06:13.680 --> 00:06:22.520
compared to direct view displays but this is clearly way behind the

00:06:19.800 --> 00:06:27.919
experience that Sony showed off in this by the way amazing promotional video

00:06:25.599 --> 00:06:33.680
that was recently re-uploaded by retro TV film and video and if we look

00:06:31.000 --> 00:06:39.880
closely yep composited got him now it was probably

00:06:37.440 --> 00:06:44.639
brighter when it was new CRTs do Decay over time but they show this thing being

00:06:41.919 --> 00:06:50.759
usable in a literally sunlit room when realistically it would have needed pitch

00:06:46.639 --> 00:06:53.360
Darkness even then with that said how

00:06:50.759 --> 00:06:56.720
cool would a land party have been if someone showed up with one of these bad

00:06:54.880 --> 00:07:02.160
boys oh it'd be sick with like a GI even not even 180 50 60 in that would be

00:06:59.520 --> 00:07:07.360
unheard of as a kid unheard of a regular CRT tube TV works by coating the front

00:07:05.080 --> 00:07:11.960
glass with a phosphor material that lights up when it gets Zapped by one of

00:07:09.520 --> 00:07:17.680
three electron guns one for red one for green and one for blue with our CRT

00:07:14.800 --> 00:07:23.000
projector we're not looking at a lit up phosphor screen

00:07:20.000 --> 00:07:25.560
so what are what is going on here it

00:07:23.000 --> 00:07:29.960
turns out it's surprisingly simple they're still using a cathode ray tube

00:07:27.960 --> 00:07:35.240
to generate the image and we can see that if we look directly down the barrel

00:07:32.440 --> 00:07:39.280
but it's upside down and backwards so that once it goes through the lens which

00:07:37.199 --> 00:07:43.759
is basically functioning as a giant magnifying glass it'll be the right way

00:07:41.520 --> 00:07:48.479
around now I alluded to this before but one of the big Innovations for the vid

00:07:45.840 --> 00:07:54.800
magic was that most CRT projectors in those days were using three separate

00:07:50.639 --> 00:07:57.520
tubes and lenses for RG and B kind of

00:07:54.800 --> 00:08:02.039
like this they were reliable but they were extremely heavy and and

00:07:59.759 --> 00:08:06.560
inconvenient to set up supposedly it took quite some time to get them all

00:08:04.240 --> 00:08:10.280
lined up correctly and something as small as a swift kick to the table it

00:08:08.720 --> 00:08:14.840
was resting on could put the whole thing out of whack again another major hurdle

00:08:12.680 --> 00:08:20.360
they faced was well you can probably guess from what we've seen so far

00:08:17.039 --> 00:08:23.039
brightness CRTs by modern standards are

00:08:20.360 --> 00:08:28.639
pretty dim to begin with and projecting that light across a much larger area

00:08:26.120 --> 00:08:34.479
exacerbates the issue how do you fix all of that

00:08:30.120 --> 00:08:37.519
okay the fp60 is no regular CRT it uses

00:08:34.479 --> 00:08:39.959
a single electron gun with a beam index

00:08:37.519 --> 00:08:44.800
tube so to get the right colors from a single gun they would modulate the beam

00:08:42.640 --> 00:08:48.959
strength then there was a fourth phosphor stripe and when that lit up the

00:08:47.360 --> 00:08:53.920
result was captured by a photo multiplier tube and that signal was then

00:08:51.560 --> 00:08:57.600
Amplified and sent to a decoder circuit which would basically check if the

00:08:55.519 --> 00:09:03.480
colors were correct and then adjust the modulation of the beam on the fly if you

00:09:01.160 --> 00:09:08.680
open this thing up the number of boards involved to properly index and decode

00:09:05.720 --> 00:09:12.800
the signals is pretty wild by the way shout out to 12volt vids for this

00:09:10.800 --> 00:09:17.399
amazing footage from his repair video a few years ago that gives us a great look

00:09:14.680 --> 00:09:22.320
by the way at the water cooling that was built into this projector now this

00:09:19.760 --> 00:09:27.920
design did have drawbacks like inferior contrast but the benefits were Brighter

00:09:24.800 --> 00:09:30.360
Images no convergence problems and lower

00:09:27.920 --> 00:09:35.240
sensitivity to magnetic interference which is why they saw some military use

00:09:33.240 --> 00:09:39.600
Sony commercialized a couple of versions of this technology including the

00:09:36.959 --> 00:09:46.079
indextron tube which was used in our fp60 as well as in the highly sought

00:09:42.120 --> 00:09:49.480
after kvx 370 watch cube a super cute

00:09:46.079 --> 00:09:52.720
4in bedside TV that came out in

00:09:49.480 --> 00:09:54.920
1989 realistically nobody was buying

00:09:52.720 --> 00:09:59.680
this thing for gaming so why don't we try a movie this definitely makes these

00:09:57.480 --> 00:10:06.320
1980 special effects not look out of place yeah I mean they look pretty good

00:10:03.440 --> 00:10:11.279
um at this resolution yeah at this brightness got to love those four

00:10:08.320 --> 00:10:18.120
textures not 4K just four this looks about how I remember

00:10:14.040 --> 00:10:23.360
watching TV in the 9s no we had more

00:10:18.120 --> 00:10:26.680
color than that the contrast is terrible

00:10:23.360 --> 00:10:29.160
fine yeah terrible so I guess what we

00:10:26.680 --> 00:10:35.120
want to know is how much of what we're looking at is limitations of the betamax

00:10:32.320 --> 00:10:39.200
format and or degradation of the tape versus how much of it is limitations of

00:10:37.160 --> 00:10:42.320
the performance of our projector so do we want to throw our DVD on yeah let's

00:10:40.800 --> 00:10:46.839
put our DVD in I think it's already in the player okay I love how delightfully

00:10:44.639 --> 00:10:52.399
easy to operate this thing is yeah it's pretty simple switches for different

00:10:48.639 --> 00:10:57.240
modes y this looks better I think that

00:10:52.399 --> 00:11:00.040
other than getting 16 by9 M which we can

00:10:57.240 --> 00:11:05.360
actually kind of take advantage of with this projector because the image isn't

00:11:02.440 --> 00:11:15.000
so small that you are basically just like well I gave up 30% of my whole

00:11:11.680 --> 00:11:16.320
screen I don't think this is a whole ton

00:11:15.000 --> 00:11:20.240
better though like a little bit I think it's a little better a little bit

00:11:18.160 --> 00:11:26.320
looking into the lens this is as bright a CRT as I have ever seen how small does

00:11:23.800 --> 00:11:31.000
it get to be CRT bright off the projection screen I'm going to move it

00:11:29.120 --> 00:11:38.720
okay moving forward careful this is like 60 80 lbs worth of I got I got you oh

00:11:34.480 --> 00:11:42.040
yeah I got hang on yeah um wow that's

00:11:38.720 --> 00:11:45.480
still really dim okay

00:11:42.040 --> 00:11:47.720
more I think that's his oh that is as

00:11:45.480 --> 00:11:53.120
much as it goes boy so we can't go any smaller than this yeah all right so it's

00:11:50.760 --> 00:11:58.959
not great for watching movies either but there were advantages to using a CRT

00:11:55.600 --> 00:12:00.959
projector even when LCD and DLP option

00:11:58.959 --> 00:12:06.320
options started hitting the market better black levels and better flesh

00:12:03.240 --> 00:12:09.360
tones no pixelation and exceptionally

00:12:06.320 --> 00:12:12.279
long tube life most CRT projectors were

00:12:09.360 --> 00:12:18.079
rated for around 10,000 hours while the bulbs in LCD and DLP projectors were

00:12:15.120 --> 00:12:21.920
only good for 1 or 2,000 they'd also gotten pretty cheap on the used Market

00:12:19.839 --> 00:12:25.800
by then so you could go with the used CRT projector and still have money left

00:12:24.199 --> 00:12:29.600
over to spend on the new noock to a screwdriver from LTD store.com to take

00:12:28.160 --> 00:12:33.440
it apart when you need to change the tube by the way guys we got a full

00:12:31.720 --> 00:12:36.959
service manual for this thing and a second projector let us know in the

00:12:35.399 --> 00:12:41.079
comments if you want to see Dan try to fix it with all of that said these

00:12:38.920 --> 00:12:46.000
benefits were not enough to keep CRT projectors in fashion like their TV set

00:12:43.639 --> 00:12:49.320
Brethren they were replaced by lighter brighter models even if it meant

00:12:48.000 --> 00:12:56.040
sacrificing a little bit of image quality for actually years to come and

00:12:52.600 --> 00:12:59.160
the last CRT projector came out in 2001

00:12:56.040 --> 00:13:02.959
the pro 1200 X from Zenith it retailed

00:12:59.160 --> 00:13:05.920
for about $30,000 and weighed around 155

00:13:02.959 --> 00:13:11.519
lb by contrast the high-end Christy Mirage 200000 DLP projector launched in

00:13:08.320 --> 00:13:13.560
the same year for 55 grand but weighed

00:13:11.519 --> 00:13:18.720
almost half of what the Zenus did and was roughly seven times brighter modern

00:13:16.800 --> 00:13:22.240
projectors have obviously gotten a lot better by the way and we'll have some

00:13:19.920 --> 00:13:27.440
decent options linked down below back to our fp60 though the only thing we

00:13:24.440 --> 00:13:29.279
haven't done yet is give a presentation
