ZX80 Minstrel Clone

[Shaun_B]

Hi,

Someone has probably asked this already so apologies if they have.

The Minstrel clone has both old and new ROMz which can be switched - so essentially it'll run as a ZX81 in FAST mode.

Is it possible to add in some upgrade to make it run in ZX81 SLOW mode?

Thanks,

Shaun
