Compaq Multi-i/o w/ IDE and FD card.

Hi all, That is real CLASSIC card because all those chips on it says appox 1986 and this card needs fixing. The compaq label for it is 46094 stuck onto intel 8272A FDC chip. Solder side etched (along top edge) says: 1985 Compaq comp. corp. flpy/prn/ser/winch bd diagram no. 000337-000 bd no. 000338-001 REV D. PCB is green. Reason: a POT resistor broken off and lost. It's located at R19. Want the value of it and appoximate resistances between 2 leads and the wiper pin. This pot is at front end toward bottom and around FDC chip area. Thanks! Newer one also by compaq, PCB is tan/reddish orange, has 1 dipswitch on one edge and much plain looking because of fewer mostly SMD components on it. I'm interested in it if you're selling one. It works well with any IDE drives and got respectable transfer rate And another reason for wanting compaq ones because IDE port is properly buffered which so many clone i/o cards I seen does not have it between ISA and IDE port!
