Interested. I've been following the a1k forum, but did not see any recent progress.8 Bit Dreams wrote: ↑Tue Jan 12, 2021 11:29 pm There will be about 100 Delfina's available soon,
Will let You know when these pop up, if someone is interested

That was quick, hopefully they build again.

There will be a batch of bare pcbs available soon,
JEDs for MACH Chips are also available, so highly likely You'll be able to build one before Prelude pops up.

Re: TF CD32 Riser Revision 2 Specification, known issues and licence
As far as I understand issue with jumping mouse affects certain CD32 boards only.
Only mouse is affected, RTC is handled correctly, and it looks like only counters are affected.
Same set of TF330 works fine on one machine, but fails few others.
As far as I understand stm32 is doing its job correctly, and any changes to extend timings on each stage of process doesn't fix issue.
Therefore I assume issue is with cpld logic.
@terriblefire
If you had some time and/or will, could you have a look at https://github.com/arkadiuszmakarenko/T ... main_top.v
and look for obvious mistakes there? Or hints what I could try? Effect is like override wasn't taking fully effect? Like PUNT was ignored every so often?

only issue i see is that things are combinatorial logic when possibly clocked logic might be betterarkadiusz.makarenko wrote: ↑Sat Apr 17, 2021 9:53 pm As far as I understand issue with jumping mouse affects certain CD32 boards only.

Can you tell which CD32 boards could possibly be affected?arkadiusz.makarenko wrote: ↑Sat Apr 17, 2021 9:53 pm As far as I understand issue with jumping mouse affects certain CD32 boards only.

@kulamario had exactly the same setup, and it worked ok on one CD32 but didn't on other.wairnair wrote: ↑Mon Apr 26, 2021 6:49 pmCan you tell which CD32 boards could possibly be affected?arkadiusz.makarenko wrote: ↑Sat Apr 17, 2021 9:53 pm As far as I understand issue with jumping mouse affects certain CD32 boards only.

I thought it was akiko's fault because one is rev-0 and the other is rev-A and for me it works on rev-A
after talking to alenppc we found that this is not it
because alenppc has some cd32 and rev0 and rev-A and it doesn't work on any of them
