I recently received a haul of some Apple hardware including lots of cables, SCSI devices, and two computers (thank you Peter!). In going through the cables, I've come across some cables that I can't identify. Please help if you are able.
One is a DB15 M/M cable that has pins 1 through 7, 9 through 11, and pin 13.
The other is a DB15 M/M with pins 1 through 3, 5 through 6, 9 through 10, and pin 13.
Thank you!
Joe
The one that is 1-3, 5-6, etc is probably a IIgs only video cable. The other one is probably a Mac video cable. But it has the proper pins to also work on IIgs.
But wait for someone more knowledgeable than me before plugging them into anything.
The upper picture is a RGB video cable for a Macintosh, which is missing the pins for vertical and horizontal sync. The early Mac video cards output Composite Sync when driving the standard monitors at 640 x 480, so those pins weren't needed. The cable should also be usable with a IIgs, with the caution that pin #7, which the IIgs supplies with +5 V, is grounded in some (non-IIgs compatible) Apple monitors. Generally it's inadvisable to connect the IIgs RGB port to any monitor other than its own (the A2M6014) or a small number of early multisync displays using adapter cables (the NEC Multisync II, and the Sony CPD-1302, 1303, 1402).
The lower picture is a cable for an AppleColor 100 RGB monitor for use with the 64K RGB Aux card in an Apple IIe. It should also work with the IIgs with the A2M6014 monitor.
Thank you both for your replies. I greatly appreciate the information!
