Nice! Yah, I was assuming you would want two pieces that interlock somehow
and use the holes for alignment/registration. I guess a retained metal
thread or indented nut in one half of the shell could allow easy screwing
and unscrewing from the other side using very short bolts or screws, and
might
Should be no problem. I wasn't sure how best to do a case yet so that's why
it has holes in the corners. One basic option is just a cover on the out
side held on your only by glue or mounting tape, and using the holes for
registration or alignment, and maybe also for glue, or just friction, make
th
That's great work! Is there enough clearance around the modern version that
a 3d-printed case could fit?

The unverified schematic I arrived at from beeping out an original NODE
DATAPAC is now verified.
Based on that best guess original schematic I made a new schematic that
uses 1 256k sram instead of 8 32k sram, but otherwise replicates the
original circuit with the way the binary counters and

Good luck.

Don't ask me why, but I think I've replicated the NODE DATAPAC in KiCAD.

Brian,
Awesome reverse engineering! Keep us posted on the progress. This is
interesting.
As far as the 74161 counters, the counters can be preloaded by taking the not
load pin (pin 9) low. In your schematic it is ti

Good luck.
