Hi I've acquired hard disk controller card. I'm in need of some information on it as well as I seem to be missing at least one PROM. The board uses the WD1100 parts with a 8X300 control processor. It has an array of 9 sockets for program of the 8X300 ( only 3 are populated on my board ). It has 3 locations for MK4802 SRAM's and a 82S191 ( also missing ). It is manufactured by Codata Systems Corp and has a part number 92-1011-01. I was hoping that someone might have information on this or have one of these boards that I could get a copy of at least the 82S191. I suspect that the 3 PROMs I do have are sufficient to run the 8X300. I would guess the additional sockets are for expansion of control. Other 8X300 controllers I've seen use less code. I'd guess the 82S191 had formatting information on it since it is on the data side of the 8X300, along with the RAM. Any help would be great. Thanks Dwight
