I have third party memory cards in my 11/750. The installation guide
indicates that they also work in an 11/730. They are from National
Semiconductor, NS753.

Does anyone know who made these cards and what part number they would be
(assuming they exist at all)?

I don't know the part number, but I do remember 3rd party 1MB memory
cards that worked in both the 11/750 and 11/730, and National
Semiconductor sounds familiar. The ones we had were populated with 2
rows of 41256s rather than 8 rows of 4164s but were otherwise
unremarkable.

I have some memory boards in my 11/750 with the following part numbers:
240-010-900, EMC Corp.
40803 Rev. K, Dataram Corporation
210 030 600 Rev. E, EMC Corp.
240 010 006 Rev. E, EMC Corp.
I *think* they're all 1MB boards. I don't have any National Semiconductor
boards listed in my machine's inventory.
