If you do a production run, do 50 of them, I will buy 15-20 pieces.
Same here, ready to take 20 boards without any support. Have here some users who are open for experiments

Re: TF534 on A2000 / memory expansions

Stephen tested it with GVP 8HC ll card,
have tested A2000 Combitec card populated with 4MB and 8MB - both setups are recognised and working.
GVP SCSI manual says that caches need to be turned off if You use it with accelerators, im almost sure this is needed for almost all cards to play well

Re: A new riser?

I have finally got around to releasing the KICAD files for the FB-32G Module on GitHub. I finished it quite some time ago, but life really got in the way. https://github.com/Bprepared/FB-32-CD32-Expansions/blob/master/FB-32G/readme.md If anyone wants the specs for module dimensions they can be foun...
