Re: BPK-72 or Bubble Memory Dummy Module + Seed Module
I disposed of a BPK-72 on eBay some years ago. I think it sold for $30. My recollection was that the thing was really power-hungry, particularly for something that stored only 128Kbits. --Chuck

The SM system with its driver, formatter, and controller is a whole other thing. I have two BPK-72s and they are interesting but 128Kb is not very big. Allison

CHM has these in their collection. Where are you located at? They don't look really complicated. I'd think one could make one if they had a schematic.

I have all the parts I need to work with the modules, I'm just missing these parts. The manual shows the schematics, component values, and layouts of both of these modules, so I can fabricate them myself if need be, but wanted to see if anyone had them handy first. Thank you again!
