Remember a while back I posted about a company in Richardson, Texas, with a bounty of crap to give away? Well, they still have it and they are more desperate than ever to get rid of it. Last time I posted a list of stuff. I'm posting that list again, but the list has grown (and I don't know what's been added). To get in on this, simply send e-mail to David Albright at <dalbright(a)hbssystems.com> and work out the details with him. I'm sure they will not be interested in shipping anything unless you are willing to compensate them well for their time (this is a business that is not very interested in becoming a vintage computer vendor). It would be best if you could actually go to their business to pick the stuff up. Please respond directly to David Albright <dalbright(a)hbssystems.com>. Here is the list: Texas Instruments 1500 (1 bay) Archive tape drive 8-port TI hub Texas Instruments 1500 (8 bay) Archive tape drive 8-port TI hub Texas Instruments 300 Business System Terminal Texas Instruments Business System 300 (blows fuse after a minute) IBM PC/XT w/System/36 interface board IBM PC monochrome display IBM System/36 Desktop (Type 5364) ADP PC/AT (no P/S) ADP MAX 8500 (dead) Archive tape drive (2) 4-port networking hubs Motorola SYS3304NY151 Archive tape drive Texas Instruments System 1000 Archive 150MB tape drive TI System V Xemix 386 by SCO Manuals Texas Instruments System 1000 (3) NEC N4810II modem (2) Racal-Vadic VA212 audto-dial modem, AC adapter, cables, manuals DIS System 36 (bad hard drive) IBM monitor CITOH 8510 printer Texas Instruments Omni 800 printer Sperry IT (PC/AT with SCO Xenix) Unisys color monitor The company wants to ditch this stuff soon so act fast or else it might be scrapped.

Semi-OT: Running CAT5 Cables

by healyzh＠aracnet.com

Does anyone know of any sources of info on the net anywhere on running a network between various rooms in a house? I'm wanting to run a line capable of handling 100BaseT from the house out to the garage, and probably a couple other rooms in the house. It is past time to move most of the VMS cluster out to the Garage, and tie in the parts already out there :^) Zane | Zane H.

HELP! ( totally OT) - Hitachi Monitor problem

This fault came about VERY gradually, having been noticeable during the warmup phase for a couple of years, but until more recently, when the duration of this problem grew to over half an hour, I figured that it might be in some way related to the aging process. Like most CRT's it has several hundred electrolytic cap's, and I'm loath to remove them all so they can be tested, though it may come down to that. I bought this thing in late '93 and it was manufactured in '91, so I have to assume it's aged a bit. The individual scan lines seemed to change both randomly and rapidly, from one to the next, in width, giving a jittering effect to the margins. On a monitor of this size it's not easy to see both margins simultaneously, but it apears that when the left margin jitters to the right, the right margin jitters to the left. Now that I've fiddled with the adjustments to such extent that the jittering is completely gone, the screen has a very substantial pincushion, somewhat more pronounced on the left than the right, though the display is VERY stabile. The width control on the front of the monitor currently has no effect. I find I'm unable to restore the conditions to their original state, not that it would help. There are a few adjustments I've not seen before. A couple, such as side-pin, Hsize, and Vsize have a second adjustment called "sub.-whichever" e.g. sub. side-pin, etc. These seemed to work in pairs with the normal adjustment. I'm baffled as to why the front panel controls don't have the same effects as before. Since I paid out a couple of K-bucks, albeit nearly 7 years ago, (mostly because I like this monitor) I'm loath to scrap it. A prefectly good new monitor of comparable size, brightness, focus, linearity (and weight), etc. costs about $400 nowadays, unless one wants to pay for the name. It's surprising that one can't easily order service documents for these monitors, but I guess it's my inability to understand how business is done these days. >> Not being in any sense expert in repairing monitors, I fooled around with >> the various accessible controls, (after removing the plastic outer shell) > >I've never been a believer in tweaking adjustments.

What's an RX01 drive worth to a commercial user?

You have to pay something for the equipment.. more than the scrappers. You told me yourself you don't like to pay much for any of this equipment - and companies don't put up with that. I have dealt with many very large companies and they ALWAYS sell to the highest bidder (I haven't lost a system to a scrapper yet). If they still won't give up the equipment for scrap(never happened to me yet) then go to a local high school and get them to type up a request letter. I have NEVER had any corporation turn down a high school for scrap equipment. Generally you can work out in the letter that you will help the school get *some* of the equipment and make it useful for them to use. I had a case where Ontario Paper had not approved a piece of equipment for disposal yet. (a REAL old 1950's mini). After receiving the letter they released the mini to the school and asked me to take everything else in case I could make it run for other schools. Bottom line is if you get on the bidder list with the asset disposal people then you should never lose a system unless you are bidding too low.

All of it goes in containers to scrappers. They have a room with three 11/44's, TC11's on each and several TU55's. I was unable to get any cooperation in rescuing any of it when the room gets emptied. I watched as a box with 100+ UNIBUS boards was loaded onto a forklift, core boards on top. It all went to the melter. They are a large company with inflexible large company policied. I have no pity for Lucent. -ethan ===== Infinet has been sold. The domain is going away in February.

Buck Savage?

by cfandt＠netsync.net

Hey gang, I need to contact William Buckley, AKA Buck Savage, but email bounces from the last known address I have on file. Has anyone heard of him recently and could get me in touch with him?
