My latest related acquisitions…

First a Philips D6260 cassette deck. Belt broke when testing but that's expected, and pause key won't work but I'll be handling that. The two holes on the side seems like made by a soldering iron, probably to pass wires. I believe I can fix that with the hot air gun, maybe I'll try.

Then, a very cute Manesth B&W 4.5" CRT. Only has an antenna input but I'll see if I can mod it to take composite.

I was a bit afraid but the seller did pack it very well and it arrived in perfect condition. The power brick outputs quite more than 12V, I'll have to check the waveform, but I'll probably won't be using it anyway.

The red isn't exactly the one, but then it's very specific, anyway they both look great, which is the primary intent anyway.

It works with a separate modulator, not really with the internal one but its weird anyway.

That's only part of my stuff… (yes, I do have a red & black vacuum cleaner as well. What? No I'm not obsessed… 🤪)

Oh yeah, again, pretend you didn't see the drawings.

Servicing the Philips D6260…

Teardown, cleaning up the case…

The pause key has a broken piece so it doesn't lock, I'll have to fix that.

Started fixing pieces on the Philips D6260:

- the pause key : added some plastic tip back. UHU plast didn't stick, it's probably PP. Cyanoacrylate seems to hold though. Tomorrow I'll add a piece on each side to reinforce as there's enough room.

- the two holes in the case bottom. Heat gun softens them, then they become somewhat elastic, I pushed them with the exoblade, then with the round part at the top of it. Not perfect but it doesn't protrude anymore.

- missing foot : I cut some part inside the battery compartment, it was already hollow, so it won't be missed. 😄

Heat gun didn't work, it only softened both part but they don't stick. I didn't want to risk burning them, so I just used UHU Plast and it seems to work fine.

Well enough for me.

Some more added to the pause key, let's hope it sticks and fits.

The glue on the pause key didn't stick when I tried to chop the added part to fit, I had to redo it, maybe this time…

Damn, broken gear…

Seems it's quite common on Philips decks… same translucent material as on this video:

Of course the dents are not even straight, impossible to do with two assembled laser-cut parts.

Ok, seems some people sell gear replicas on ebay…
Some not 3D printed so probably with better details for such small part…

Continued, servicing the Philips for my :

I managed to actually fix the pause key by soldering a tiny part cut from some leftover piece of the same material, using the hot air gun.

Now on to the Manesth SMT-901 B&W 4.5" TV (branded as Skytek in the US I think)…

First, let's remove this disgusting tape leftovers on the box…

The inside is very clean as well…
There are 4 chips inside, 2 * KA2912, KA2102A, and a uPC1379C.

Luckily there are some nice cables with connectors for video & audio output from the smaller PCB…

I think we could fit a 3.5 jack on the back for CVBS+audio in…

cc @jelora @tavernejohnjohn

Yeah, it'd fit in perfectly with a small PCB. I've ordered 5pin jacks so when not plugged in the TV will just work normally.

Then I'll hook on these connectors here…

First attempt at injecting composite… kinda works but it's ugly.

I attached wires directly to the RCA jack so maybe…

Also, I'm using a very crude AD724 based composite generation circuit which works when it wants…

Ah now it's better! Well, still not perfect.

I wonder if the signal is what is expected by the board though, maybe it would need some amplification…

AD724 vs K2912…

Maybe it needs higher DC level…

The uPC1379C wants 1.5V peek-peek but that's for sync, and sync actually looks quite correct anyway.

poke @jelora @tavernejohnjohn

Oh, and sound works well, not that needed since there's a speaker in the but well…

@Armageddon euh non, le foot c'est pas mon truc, pourquoi, ils ont pompé les couleurs de l'ORIC ? On va leur faire un procès !!! 😅

@mmu_man @jelora @tavernejohnjohn Le rouge va bien, avec celui de l’Oric Atmos :) Il doit y avoir des cartes d’acquisition pour l’afficher via un pc sinon ?

@mmu_man i was lucky to have pravetz-8d - bulgarian clone of oric in childhood. i learnt 6502 instructions on it. it was very hard without documentation in soviet union, and almost everything looked like reverse engineering.

later i was also lucky to get the russian clone of zx spectrum, but though it was more widespread, and it was possible to find programs for it, i sincerely liked pravetz so much more!

you can find here my page on pravetz-8d: http://norayr.am/RetroComputing/RetroComputing.html

@tanakian@ծմակուտ.հայ oh yeah, _Dbug_ has one in his collection:

@mmu_man @mmu_man yes, i remember when he bought it. (: i was in contact with him and oric community on usenet. (:

@կողմնակի անցանց @mmu_man oh, commented you with other account.

yes yes, i remember when he acquired it. i was in contact with him and oric community on usenet - comp.sys.oric group.

and several ceo mag issues had covers generated by me, like this one:
