Oric extender - a basis for DIY projects and experiments

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.

I'm far from being a specialist but I would say it's an Electronic board with some integrated circuit on it.

It Is the same color of the Oric

I hope it helps :D

Indeed!
Well, I'm trying my best to make good looking video clips - unfortunately it takes more time than to create another hardware :).
Anyway, as promised there will be release - just don't be too 'censorious' to the quality of videos...

ORICART looks very good and I would like to know where I can get one.

However I don't undertand the link between a basis for DIY projects and a smart cartbridge system.

Do you think I could prototype an OTA8REG with this basis for DIY projects ?

I think of using an ESP32 for the core CPU, GPIO and wifi and surround it with:
- either a 74HCT244 or 2N7000 or TXS0108 or CT2065ST-ND for bus interface adaptation
- a few 74ls08 gates and a CT2065ST-ND for configurable address decoding.

Is it possible with an Oric Extender ? If yes where can I get one ?
