Doom on 1983 Sinclair FTV1 TV80 Mini Flat CRT & Teardown

You're so funny: "The quality is not that bad. I can see something at least." LOL!! :-) That is cool though, I completely agree.

yeah. I was so fascinated that this thing was working at the end. I am not a HF expert and it took me a while to adjust the modulator. 😅

There's something really magical about these tiny CRT screens, especially one with such an unusual design. Thanks for sharing this with us!

[@diegocesar316]

In the 80s we always had to use, with our home computers, the TVs that were "left over" or the "older ones" ... the new ones "were not touched" ... at that time, I only knew a CASIO model that was LCD (late 80s) or some model of the all-inclusive radio-tv type .. but this sinclair model is much smaller, a marvel really.

[@connectorxp]

I know how it was, the living room TV was a no go area for the home computer or the NES, later I was allowed to use it, it was like winning something.

[@diegocesar316]

@@connectorxp when my family finally gave me a home tv to use with my commodore 64, this was the same one we had seen the 1978 soccer world cup with !!. (philco b / w 14´) :) (1988)

@@diegocesar316 I used a black and white TV before my parents "cascaded" the old color TV in the bedroom, and got a fancy new one in the living room. On one Christmas holyday I was allowed to play on it :) And now, my young one, asked me when the commercials or DLCs are coming to the Super Mario Bros on the NES... I was in between crying or getting angry.

[@diegocesar316]

@@connectorxp it's funny how, nowadays, 80s home computer collectors want "image purity" and "4k-like" image qualities on computers from that era ... when not even the creators of them expected them to be seen with a quality more than "mediocre". which is how we qualify the image of that time today.

[@connectorxp]

@@diegocesar316 I see them using those upscalers and other expensive gadgets. For HD Gameplay I use a moded NES and SNES Classic mini, but they lack the authenticity of running the original via analog connection with all the imperfections that entails.

This content is exactly the reason I come to KZbin. I did a presentation about this TV recently as part of the history of Sinclair. I made my own ZX 48k from a Raspberry Pi Zero embedded in a ZX 48k keyboard, but didn’t have a TV80 to pair with it. It’s so great to see one working. Thank you for doing this.

[@adriansdigitalbasement]

Ah you got shocked from it! Yeah it's wild how the phosphor area is flat versus the Sony Watchmen series with the curved phosphor area.

I was luck to work with Jim Westwood for a number of years who designed this and many of the other Sinclair products. Some of the early Sinclair stories are great.

[@Dedubya-]

The UK PAL(i) sound spacing is different to European PAL (bg) sound so that might be the problem if your Sinclair TV is a UK version and the modulator is for European TV.. Great to see you got it working!

[@grumpybollox7949]

thanks for the clarification

[@CPUGalaxy]

👍🏻

[@SeanBZA]

Yes System I used a 5.5MHz sound carrier, while B, G and K used sound carriers of 4, 4.5 and 5MHz for the sound carrier offset, so it was common to have a TV set where if you selected the wrong sound system you got either good video and no or poor sound, or great sound and garbled video. then you had colour carriers, which added extra condfusion, as SECAM and PAL used the exact same offsets, but slightly different colour carriers and offsets. Then that hybrid MESECAM, using 50Hz 625 line SECAM channel specifications, and 60Hz 525 line video. Likely the modulator was for BG, but Sinclair generally was I, so you either had to solder in new sound carrier filters for use in other parts of the world, or use them for video only. Still have a JVC colour CRT TV set, that was adjustable for all TV systems, B, G, I, and which had a battery operate mode, along with a small Colour CRT. Worked last time I had it on a few years ago.

[@hopje01]

@@SeanBZA PAL BG sound carrier (mainland Europe) is 5.5Mc from video carrier, in the UK it is 4.5Mc.

[@SeanBZA]

@@hopje01 Been a long time since I did any conversions on TV sets though. Do remember robbing the filters out of dead sets to do that though, as it was easier to get them that way, and dead TV sets were easy to get as well. Did do some tuner conversions, where you replaced the horrid tray of drift pots with a 4 way switch and 4 10 turn trimmers, as there were only 3 TV stations and a VCR around most commonly. Sony and the GCS conversion kits, where pretty much it was a BU208D, a heatsink for it, with a lot of resistors, diodes and capacitors, plus a poor copy of a board layout per set, which showed you where to put the assorted bodges in. Strangely enough they did work most of the time.

@1:07 Whoa! You've got some mad editing skills. :)

[@necro_ware]

Hehe! Very cool :) I just shortly watched a film "Micro Men" (available on youtube) about Sinclair, Acorn and others and a story behind BBC Micro. In that film they mention the Sinclair portable TVs and here you go, you have two of them! Nice to see it in action :D Thank you!

[@roborb1960]

Great stuff! I still have mine although not used for ages..... The battery was a flat pile lithium 6V P500 made specially for Sinclair by Polaroid and was ridiculously expensive and would last all of 2 hours tops.... . In the end I ran it from a power pack. TV reception was poor so I used a coax chassis socket soldered to a coil of stiff solid core wire wrapped around the aerial and then plugged it into the main house aerial. Hardly a mobile set-up! Snooker was a challenge to watch.... My bedroom tv I then upgraded to a Vega 402.... The problem with the picture flipping is just due to lack of signal... With patience and a lot of moving the set about the room, the picture would eventually settle but usually when the unit was sat on top of the bedroom wardrobe! .

[@EdwinSteiner]

This little TV is a masterpiece! Very wholesome to see it have a little fun in old age. Style points for the setup with the ISA backplane!

[@PeterHaida]

Great video Sony made a similar right angle CRT around the same time - they produced many different models and screen sizes up to 4" like the FD40 and smaller FD10. They didn't require a lens in front, just some clever electronics to sort out the distortion. Traditional scan coils were used, unlike the Sinclair's electrostatic display and some models are still quite cheap to buy on ebay.

[@CPUGalaxy]

yeah, i have a FD10 and ofcourse I planned another video with that model. 😉

[@MadRC]

This is fantastic 😎

[@CPUGalaxy]

[@grumpybollox7949]

wow really cool little things, never knew they existed really. seems its like today, when were shrinking our computers into smart watches, but back then we wanted our TV with us

[@SCP-POOL]

The ISA backplane was before my time, but I think this is a better way to do things. You want to upgrade your PC, you get a new PC card, you want a video card, sound card etc... modular would have definitely been the way to go...

[@AWoh51EIbvd]

This is super cool. Nice video, very impressed.

[@peterwiegel4778]

I've had such a device in the later 80th, where a electronic shop named Völkner sold out these for a very low price.Than I need to collect used polaroid cardrages to get batteries.

[@JosiahGould]

You should try and pick up a device called an Agile Modulator. They're used quite often in the ham radio community for TV broadcasting. I have one that I used to have hooked up to a Raspberry-Pi to feed video over the old cable hookups in my house. Blonder-Tongue models are fairly cheap and easy to use. Feed it a video and audio signal, choose what channel to broadcast, and hook up a small antenna - boom, TV transmitter.

[@CPUGalaxy]

Sounds good. need to check that. 🙂👍🏻

[@RW-nr6bh]

I nearly bought one of these secondhand in the mid 1990s. It was difficulty getting replacement batteries that put me off.

[@GodmanchesterGoblin]

I still have my FTV1 from SInclair (I bought it new from Sinclair via mail-order in 1984). Of course, there's no analogue TV transmission here in the UK now. I am tempted to see if I can get a signal into it.

Cool one, I have a Sony Watchman somewhere, it has something similar but it's more like a flattened normal CRT with magnetic deflection instead of electrostatic. Might try this out if I find it.

what about tcp port 666?

[@airattoz]

Looked better when assembled, with better aspect ratio and more shielded from ambient light.

[@Dex99SS]

Has anyone else done "CRT's" like this back then? Or is this almost more of a DLP? As it isn't a tube, nor a cathode ray one.... though it sort of is? But it really isn't.... as it's projecting it from the side.... As one who's been into tech since my own inception in the 80's, I can attest with acute assuredness that I've never seen this before.

[@CPUGalaxy]

so this is definitely a CRT. We have an electron gun, we have grids for focus, we have deflection of the beam, we have anode voltage, we have a Phosphor coating on the screen... All this is the definition of a Cathode Ray Tube. Just a bit in another form factor. DLP is a completely different technology.
