Re: ZX81 ULA-in-a-CPLD

Very nice to have some proper replacement for our aging HW.
Any plans for further functions, like a super ULA?

Re: ZXPAND and Lambda 8300?

I seem to remember something about the Lambda using 208 cycles per line, whereas the ZX81 uses 207. This is strictly a vague feeling, not something to rely on...

Re: ZX81 ULA-in-a-CPLD

But without the familiar video-disturbance patterns, how will I be able to debug where the code begins/ends?! I'll be lost forever in an endless loop! ;)

Re: Sketchy - An online screen designer

Just tested it. Works nicely, but the direction keys do not work properly for me. The position is moved, but a '?' is also added.

Re: Bad Apple UDG

I am working on the encoder code, but going is slow. Anyone "needing" it can of course get a work-in-progress, but it requires a strong stomach for bad code, as well as some python fluency :)
Contact me in PM for more info.

Re: If you like your submarine simulations fast, arcadey,...

Oh, and both were switching PSUs with voltage settings. It did not matter what voltage was set, 7/9/11V yielded the same results on both. I haven't looked at the troublesome PSU in a scope, but it might be time for that.
