My lab has a 3/160 and a 3/260 and some image processing hardware which is the heart of our operation. Unfortunately it makes a lot of noise and would live very happily in the machine room next door except for the length of the Sun-supplied keyboard cables. Now I have heard conflicting things about this: apparently there is someone selling extenders for approximately $5-600. My question is: has anyone tried just sticking a longer 15-pin cable between machine and keyboard? Without any fancy repeaters. Did it work? How long was the cable. I'd like to go 100 feet or so. Thanks, Mike Sokolov

Thanks, I've seen 2/120's with extended keyboard and mouse by just using normal rj11 straight-through extension cables. Probably cheaper than doing the 15 pin, although I've not seen runs that long made -- ours are more like 20 feet.

We're running a SUN-2 monitor and keyboard at 70 feet using three sheilded pairs in a cable, one for the keyboard and mouse and another for the video. The monitor and video board are ECL which was necessary for that long a run, but the mouse and keyboard are TTL levels. If you want to build your own "amplifier" it'd just require a +5 volt supply at the KB/mouse end and a non-inverting line driver IC.
