Found the doc - it makes no mention of the maximum drive size, which means
it likely is 8G (If it beat that limit, I'm sure they would have said so).

Rom is 16K, and the card can be jumpered for:

Docs say to set 'C' drive to type '1', and if present, set 'D' to type '2'. I don't
recall if I never used it with 2 drives, but it worked well with one drive.
