Would it be possible to recreate the ULA logic in a modern FPGA? And if so, to use it as a direct replacement in an original Sinclair/Amstrad?

- johnklos 4y agoNot only possible, but doable. Not only doable, but already done :) https://www.sellmyretro.com/offer/details/vla81-%3A-a-replacement-for-the-sinclair-zx81-ula-38492 https://www.sellmyretro.com/offer/details/vla81-%3A-a-replac... https://www.sellmyretro.com/offer/details/vla82-%3A-a-replacement-for-the-sinclair-spectrum-48k-6c001e-_7-%28or-earlier%29-ula-38493 https://www.sellmyretro.com/offer/details/vla82-%3A-a-replac...
- krallja 4y agoYes, but at that point, couldn't you put the rest of the device in the FPGA too?
- rwmj 4y agoYup! https://github.com/MiSTer-devel/ZX81_MiSTer https://github.com/MiSTer-devel/ZX81_MiSTer
