Do you like the idea to convert it to Sega SC-3000/SG-1000 (16KB memory expansion required)?
Don't know much about the system but browsing through the specs it looks like a fairly trivial endevour. Wondering if there's any real demand for it though.
If you want to know about our SG-1000/SC-3000 enter in our FB page "SC-3000 Survivors". The hardware is based upon ICs very common and simple.
