They are discussed in the Technical Reference manual for the IBM 8514/A and in "Jake and Buds" book on the 8514/A (references given below). In case you don't have either of these on hand the bits are : Bits 654 Description --- ----------- 000 Reserved 001 IBM 8507 (monochrome, 1024 x 768 interlaced) 010 IBM 8514 (color, 1024 x 768 interlaced) 011 Reserved 100 Reserved 101 IBM 8503 (monchrome, 640 x 480 noninterlaced) 110 IBM 8512 and IBM 8513 (color, 640 x 480 noninterlaced) 111 Reserved The bit numbers correspond to how they are stored internally in register 42e8 on an 8514/A. The corresponding pin numbers on the VGA connector are : Pins --- |||----- Pin #11 MID0 ||------ Pin #12 MID1 |------- Pin #4 MID2 The references are : Personal System/2 Display Adapter 8514/A Technical Reference p/n 68x2248 Cost ~$10 Call the IBM Technical Books Ordering Dept.
