No, I'm re-engineering the original one. I do have some details, from the time is was designed, however, not enough to completely rebuild it without some reverse engineering.

Re: P.R.E.S. AP5 - Original and Re-Design

The best solution, I think, would be to reinstate the SCSI drivers in ADFS 3.31.

1) On page 12 of the manual the text at the bottom implies that the 62256 is the only supported SRAM type, but the table above states 16k RAM for Modes 2 & 3. Does this mean that these modes don't work with the 62256? That's possibly a typo in the manual. These modes should work fine with a 622...

C304/C315/C318/R306/R313 - Supply line decoupling - these work with L301 so they all need looking at.

Or - is it just a really noisy motor?
