Okay, someone out there may have an instruction sheet they could scan for this: I have around half a dozen ISA parallel/serial expansion cards that I need the jumper data on. These are only marked on two lrger chips as Winbond W86C551's and the only other marking is screen printed at the bottom near the slot. It reads "DIO-222-OHM REV. A" which I assume is it's model number, probably stands for Dual I/O model 222. It has a COM A fixed to the filler card at the backbone and a COM B on a ribbon on an expansion plate. There is a LPTA and LPTB just the same. It has a set of jumpers on the lower side below the lower of the two Winbond chips and it's amrked as JP1 and has three rows tall and 13 rows wide. The left has 1, 14 and 27 screened on the pc board and the right side has 13, 26 and 35 screened on. I've used a few that were previously set as LPT2, LPT3, COM3, COM4 but as I come across machines that need a different setup I'll need a set of instructions. If anyone has a copy that they could scan and attach as a graphic, or could fax to me (502-756-6991) or could photocopy and mail to me I'm sure I could work out something to repay them. -- -------------------------------------------------------------------- Russ Blakeman RB Custom Services / Rt. 1 Box 62E / Harned, KY USA 40144 Phone: (502) 756-1749 Data/Fax:(502) 756-6991 Email: rhblake(a)bbtel.com or rhblake(a)bigfoot.com Website: http://members.tripod.com/~RHBLAKE/ ICQ UIN #1714857 AOL Instant Messenger "RHBLAKEMAN" * Parts/Service/Upgrades and more for MOST Computers* --------------------------------------------------------------------
