Re: ZX81 as a ZX80 by just changing ROM?

I have done this with a ZX81 and can confirm it is the cheapest way to get a ZX80. I burned an EPROM with the ZX80 image then added the resistors to the CPU and all is good. Paul mentions a reset problem which I overcome by adding a reset switch across the reset capacitor. If I didn't get the "K" cu...

Re: Which ROM for Minstrel 3?

I would also add the double speed ROM to that list, which really does speed up some aspects of BASIC and is in use on two of my zeddies.

The thread and ROM image can be found here...

Re: vLA81 ULA and 16/32K internal RAM

I have said it once before and will say it again Lardo your refurbs, expertly done then passed on at a good honest price with an equally honest listing, does you credit and it 's nice to know there are at least 40 odd people who are part of our world, hopefully, with a decent tooter to play with.

Re: vLA81 ULA and 16/32K internal RAM

Excellent post. They are there to be used and abused imo. not polished or put in glass cabinets.

My...

A change of ULA curing this completely and testing the ULA on other systems which then exhibited the same fault confirmed a partially faulty...
