Yo, Tony here (Sharkonwheels on VC)
Got any boards left? CPU board, ECB backplane, and (if ready) FDD/IDE board.
Thanks! Yes, I have several PCBs left. I have N8VEM SBCs, ECB backplanes,
and ECB bus monitor PCBs. I just received the ECB bus monitor PCBs and
haven't finished building mine yet. Some of the other builders are helping
out by taking the lead on the first ECB bus monitor for build and test phase
while I continue work on the Disk IO board.
The ECB backplanes are going fast which rather surprises me. I have only a
few left and am going to have to reorder. The builders who have ECB
backplanes seem to like them though.
The Disk IO prototype is working fine so I am writing up the schematic and
doing the PCB layout right now. I'll be posting the schematic and PCB
layout for some much appreciated peer review in the next few days. I am
still doing quality checking on them to make sure they are right. The IDE
portion looks OK but the FDC portion is complex and has me concerned. The
big difference between the prototype and the manufactured PCB will be
several option jumpers and a "feature" connector to help builders who want
8" drive support.
Thanks and have a nice day! Please contact me offline if you'd like some
PCBs. They are still $20 each plus shipping.
