build old SCSI
remembering the old days and after a conference (link) on a Spanish friend channel, I am interested in building a mega-scsi and a scsi-novaxis.
Do you know if there are designs to be able to manufacture them?
I do not mind having to do 10 pcb, s of each if I get my novaxis and my mega-scsi of 1MB.
Thanks a lot

many thanks,
PAC has provided me with the link to the mega-scsi scheme (now I have to look for the most difficult component: MB89352a).
We keep searching for the novaxis.
Adapters such as the scsi2sd or aztecmonster can be very interesting with this devices.

MB89352 in DIP format can be found on ebay without difficulty:

The other format seems still sold in Japan but it not easy to buy it and it's expensive.

Mega-scsi is more powerful than the Novaxis but it is more expensive.
