Easily. > Could you point me to a reference for how such a board could be built (e.g., circuit diagram)? Are these 16K EPROM and edge connector standard components that I can still obtain easily? (Aren't they from 80's?) You really just need a 16K eprom with the right edge connector for the cartridge slot. The slot details are in the technical manual which has been scanned and can be found online by googling. >> Alternatively you could give SE Basic a try.

I saw some mentions of replacing 2068 ROM with ZX Spectrum ROM. How do you feel about this approach? The 2068 uses a 24K ROM. I'm not clear if this is on two separate chips. It's the HOME ROM that you want to replace with the Specturm ROM (or if you're burning an EPROM, optionally the SE Basic ROM). > > I also saw some mentions of "twister board" allowing interacing with Spectrum accessories. This sounds very useful considering that I have Divide interface. Together with emulator cartridge or ROM exchange, this will allow easy access to Spectrum software. But it looks like I will have to build one again. Do you have access to the build information? > The 2068 has the same edge connector as the TS1000/ZX81. The twister board converts it to match the ZX Spectrum. After the conversion most ZX Spectrum peripherals will work with the TS2068 with the emulator ROM. Some of them (including divIDE) will work to some degree with the original ROM too. Unfortunately I don't have any details of the build, however you could work it out by comparing the TS2068 tech manual with the ZX Spectrum tech manual. -Andrew
