Yes, but I wonder whose actual bubble memory part is inside the cartridge.
Do you have a broken one to sacrifice for the quest for arcane knowledge?
I wonder whether they put the bubble controller inside the cartridge.
Probably not, since there was no sense in duplicating that cost.
The only manufacturers that I heard of were:
vendor capacity capacity

Intel 1M 128K
Intel 4M 512K rare?
Rare? Probably not. That's what Intel put on their bubble memory cards
for the PC. I have one right here, it's an Intel iPCB-75 PC-BUBBLE(tm)
Card. It uses an Intel 7114 Magnetic Bubble Memory (MBM). They only came
with one MBM but the manual says that the card can hold two of them. One of
the neat things about this card is that even though it has an 8-bit ISA
connector it also has a connector on the rear of the card that lets it be
used in other machines. Hmm, I wonder how it would work in my Altair.
