BA123 power supply, AUI cables

Depending on what "short" means here, you may be able to make your own with a pair of DA15s and some 15-pin ribbon cable. It doesn't have the right transmission-line characteristics, but for sufficiently short cables that doesn't matter in practice. (I once experimented; I had to get up to something like three metres before I started getting a significant level of errors.) It seems to be difficult, at least for me, to find out just sort sort of signals, in the electrical sense, run over AUI. But at 10Mb, bits are roughly 50 feet long (at these frequencies, signals in copper travel largely by skin effect at somewhere between .4 and .8 lightspeed, depending on the details of the cable), so it's no surprise that you can get away with a lot at cable lengths of only a foot or so. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
