Well I managed to get the pin outs for the 8 bit slot form the IBM technical referance manual but the guy who got it for me didn't get the pin assignments for the 16 bit part. Does anyone have the manual?, and if you do could you give the pin assingments. It's page I-30 and I-31 the pin numbers are D1-D18 and C1-C18. I don't think this would violate any copywrite laws but someone let me know if I'm wrong. Any and all help is much appriciated. Derek Small Miami University (OH) System Analysis/Physics
