These cannot be loaded with ZXpand Comman...

Re: How to repair a ZX81XT extender board (or slot edge connector)

I have used a ZX81XT to get space between my Lambda 8300 and the ZXBKBv3 keyboard controller I've built. But yesterday all kinds of chars came randomly on the screen, but the computer worked. It was hard to use, as most of the chars on the screen were corrupted. This was very frustrating. Finally I ...

Re: ZXPAND and Lambda 8300?

I can report that the ZXpand works ok with the Lambda 8300. Since the Lambda 8300 has a different I/O-port for detection NTSC/PAL, an unmodified ZX81 ROM will assume NTSC and therefor the screen is unreadable. You can work almost in blind and use CONFIG "X" at the end, to change back to Lambda's bui...

Re: 28C64 in 2364 socket (28 pin to 26 pin)

To fit an 28 pin EEPROM in a 2364 PROM socket needs a conversion circuit. It's built but not tested. I couldn’t get it to work. But then I found that the EEPROM contained 00h’s every time it had been tested. Then I realized that /WE should be tied to 5V and not floating. The two pins were next to e...
