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.

Subject: WTB: BPK-72 or Bubble Memory Dummy Module + Seed Module
Currently working on restoring some bubble memories and I'm looking for
some modules originally included in Intel's BPK-72 development kit,
specifically the Dummy Load module and the Seed module.
http://archive.computerhistory.org/resources/still-image/Intel/intel.dummy_…
These are used for testing a bubble memory system as well as repairing
bubble modules which have had some sort of failure which requires manually
re-seeding them.
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!
Josh
The seed module is simple.? 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.
