We have an Allen Bradley 8000-MBC Bubble Memory that has failed.
Does anyone know how to test this unit?
Does anyone have the schematics for this board?
Is there anyway to convert this to another type of memory?
My thanks for any help that you can give.
i have not seen bubble memory in 25 years.
do you have a complete schematic of this board?
you could probably use static ram, but u need the plans.
a cpu sends an address to the address bus and reads or writes to that memory location.
and usually just a read/write line. ( in simple terms )
bubble memory is quite complicated.
