Re: ZX PRINTER on the ZX80

Thanks a lot Moggy. That's an interesting read.
I hope I find time to add this into the ROM some time so COPY and LPRINT will be available together with the ZXPand commands....

Re: Yet another repair

Yes, the ULA needs to be working to create a clock signal.
Is your Mainboard unmodified? Or could there be a short circuit some where in your Mainboard? Which ICs are socketed?
Can you please also measure your 5V supply?
In which continent are you?
Kind regards Paul

Re: Yet another repair

The Oscillator is 6.5 MHz and can be bought at Reichelt.de or on SellMyRetro.
The resulting Clock going to the processor is half of it, 3.25MHz.
These resonators (3 Pin) normally dont break. If its dead its normally the ULA that fails.
Kind regards

Re: ZX81 ULA-in-a-CPLD

Yes, that price is more than acceptable ;)
The danger might be that at low prices the demand might be quite high.
I'd take five for example.
Andy, are you soldering them manually?
Any other plans for the coming years? :mrgreen:
