03/07/1991 I desribed a unknown card on a shared bbs forum, and as it was in those days, the message wended it's way thru many bbs and eventually I got an answer! Walter, Your info on the 6Pack Clone MultiFunction Card: J1 on rear bracket is serial...COM1. J2 is parallel port. Should be standard printer pinout...but MAY vary. J3 is game port. Should be standard game port pinout. The switch at middle bottom (6 position, with room for 8) is the memory configuration switch: S1,2,3: set starting address. S4,5,6: amount of RAM on card. Typical: ON-OFF-OFF ON-ON-OFF (starts at 256K, with 384K onboard) JP3 is parity enable select: ON = Parity ENABLED. The group of 8 pins in a nquare (actually 9 pins) is the PORT ENABLE block,...should be marked "JP2": ZDDDDDDDDDDDDDDDDDDDDBDDDDDDDDDDDDDDDDDDBDDDDDDDDDDDDD? 3 000 x00 3 000 0x0 3 00x 3 3 x00 x00 3 0x0 0x0 3 00x 3 3 x00 000 3 0x0 000 3 000 3 CDDDDDDDDDBDDDDDDDDDDEDDDDDDDDDDDDDDDDDDEDDDDDDDDDDDDD4 3 COM 1 3 COM 2 3 378h 278h3 Clock 2 3 3 3 3 Parallel Port 3 3 3 3 3 Configuration 3 3 @DDDDDDDDDADDDDDDDDDDADDDDDDDDDDDDDDDDDDADDDDDDDDDDDDDY JP1 (7 position header):...IRQ ENABLE block: ZDDDDDDDDDDDDDDDDDDDDDDDBDDDDDDDDDDDDBDDDDDDDDDDDD? 3 0x00000 xx00000 3 00000x0 3 000000x 3 3 x00000 000000 3 0000x0 3 00000x 3 CDuse thisDDBDDDDDDDDDDD4 Clock 3 Printer 3 3 IRQ 4 3 IRQ 3 3 IRQ2 3 IRQ7 3 @DDDDDDDDDDDADDDDDDDDDDDADDDDDDDDDDDDADDDDDDDDDDDDY This should get you going, let me know how it works out!
