More common than dirt. I'm not sure, I think the ugly little 707s may have been more common, as they appear to have been popular with real estate agents, and you just can't swing a dead cat without hitting a real estate agent (now THERE's an idea for a new sport!). -dq

Switching PSU Theory of Operation / Repair Tips & Techniques

by dhquebbeman＠theestopinalgroup.com

My Prime 2455's PSU died last week. A replacement has been offered and will undoubtedly arrive sooner than a repair will take place. But I have to deep-six this monster, as they just don't make them anymore, and buying a used one >from a reseller is likely to be cost prohibitive. So, I'd like to eventually repair it. It's a monster, and potentially lethal. From poking around with a voltmeter, I can see that it chops the AC to DC and doubles the voltage to about 280 volts, one positive supply, one negative supply. >From there, I'm lost. Has anyone every written up a general description of troubleshooting and repair techniques? Is it even possible for devices that vary in design not only from manufacturer to manufacturer, but wven model to model? tia, -doug quebbeman

TI Silent 700 terminal

The Silent700 model I'm most interested in was the unit that had the dual digital casette drives that were arranged above the unit. I haven't seen one since the 70's; my Sol uses a keyboard from one. Anyone know what it's model number was? -doug quebbeman

TI stuff and car dealerships

by xds_sigma7＠hotmail.com

Hmmm... this whole silent 700 thread makes me wonder about the whole TI-Car dealership connection.. I recently bought something like 13 or so TI-990 boards from a guy who said he got them from a car dealer... Unfortunately, no docs, no cables, no chassis, not enough to assemble one computer, etc. Turned out to be components of 2 seperate machines, have one 990/10A CPU, one board from a 990/12 CPU, one meg of cache, and a bunch of random comm boards. Also got a funky TI video terminal from him, hasn't arrived yet but it uses an optical cable... damn odd Will J ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
