Neither the new PSU or the replacing of the ZX8301 helped :(

The issue remained the same...

It could also be a problem decoding addresses so the ROM content is valid but the ROM addressing is faulty, so it reads mush? @Dave, I don't have a manual unfortunately. I am not sure as it seems to r...

Still possible to get Minerva ROM

HI there,

Is it still possible to get the Minerva ROM? I noticed that it was normally housed on an

Re: CST Thor 1

@Dave.... Just a quick thought, from your comment! Could my issues be caused by a faulty ZX8301? RAM management. I know they can be damaged by plugging in a RGB monitor.

Re: CST Thor 1

Hi, I sent a PM, for your address and I will send you the Thor 1 Expansion boards. I have never had them working, as I do not have a Power Supply. I was going to use a small ATX PSU with the ATX POWER_ON as a switch. But this is on my list of things to do... Hi Derek, No PM received yet but I have ...
