ORIC + SMT-901 CRT + Philips D6260 K7 : servicing hardware

This is the right place to discuss on how to implement hardware vsync, adding a VIA or AY chipset, puting multiple roms, or how to design a new flash expansion card.

ORIC + SMT-901 CRT + Philips D6260 K7 : servicing hardware

Post by mmu_man »

I recently bought a cute B&W 4.5" CRT (Manesth SMT-901, also sold under the Skytek brand), and a Philips D6260 K7 deck, both with a beautiful black and red casing, although the CRT's red is a bit less orange but it still looks nice with the Atmos:

I started servicing the Philips deck, I fixed the pause key, but it needs a new gear which I ordered from eBay.
And I'm adding a composite input to the CRT for better picture and to skip the modulator (although instead it needs an AD724 module to generate the composite).

I've been posting images of the progression on this thread on Mastodon.

I successfully got the composite+audio jack fitted in the CRT case now, it only lacks the cables to go back to the tuner for normal function.

I just finished the composite input mod on the 4.5" TV, it works very well now. And I can still use the tuner if needed.

Hehe… the only annoying thing is the moving patterns from the color signal I suppose, possibly it'd look better by using the Y signal from the AD724 I used for composite generation (it also has an Y/C output). But probably it'd look more plain though, without the color patterns.
