IBM 5150 and Full-height 5.25" Floppy Drives

by RMaxwell＠atlantissi.com

I've been restoring a NorthStar Horizon that had its 5.25" full-height double-sided floppy drives removed long ago. A friend has given me another computer with those drives, but when I inspected it, I realized that it's a true-blue IBM 5150 PC in very good condition! The 5.25" drives' front panels are marked with the "IBM" logo, which makes them less-than-genuine for installation into a pre-IBM microcomputer. There may be parties that would protest stripping one "classic" to restore another: I'm hoping if there might be someone interested in both/either: - acquiring the 5150 as is (256K RAM [4 rows of 64K] on motherboard, plus 256K more on expansion card, no monitor); - supplying (Tandon TM100-2?) full-height DS 5.25" drives for the Horizon. The big hole in the Horizon's front panel really calls out for full-height drives. Any help/ideas/suggestions? I'm located in Southern Ontario, Canada and am contemplating attending VCF East.

Three lead neon lamps

by jrice54＠vzavenue.net

I'm looking for a source for several three lead neon lamps. I purchased a Sgi Galileo video analog breakout box and two neon lamps on the PC board are broken. There are no makings on the lamps. I assume they are some kind of protective device. I've been browsing several lamps sites and have only seen two lead lamps. James

Atari Mandala VR System

by wayne.smith＠charter.net

I'm looking to buy (or at least get a chance to look at) an original Mandala virtual reality system for the Atari - the one that was sold by Vivid beginning in around late 1989 or so. Basically works like the Playstation Eye Toy. Anybody have one or know who does? -W

new hamfest finds

by rigdonj＠cfl.rr.com

I went to a little hamfest today. Brought back another SWTPC Function Generator and two OLD or homemade (or both?) vacuum tubes. These things are weird! Other finds include the main unit for a Pace MBT desoldering station (no handpiece or tips :-(. Also a HP 12C calculator and NOS military lead acid battery from 1953. It's about 2" square and about 5" tall and is made of clear plastic so everything is readily visible. It's never had acid put into it and has never been used. It's sort of cute and it makes an interesting show and tell piece. Pictures later. Joe

Actually, small transparent lead-acid batteries (usually with the three balls in a column) were still made up to the 1980s. Professional flashguns and some "portable" phones used them. -- Pete Peter Turnbull Network Manager University of York

more on printing terminals

by akb+lists.cctech＠imap1.mirror.to

I've been getting interested in printing terminals. (I am seeking professional help for this, but meanwhile...). Is there a device which is a good modern (correcting) typewriter, true letter-quality (daisy, thimble, golfball) printer, and also a terminal? Plenty of typewriters were made with serial or parallel ports, but I don't know of anything with both correction tape and a control key... Correcting Selectric II's came out around 1973, and the LA36 Decwriter II in 1974, with the Selectric III and LA100 still being available at least into the mid-eighties... was there really no perceived market for a product that combined the strengths of both? --akb

by jdaviscctalk＠soupwizard.com

Hey, saw this PC-380-AA on ebay, which I believe is a Professional 380 turned into a VAX console: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=1479&item=5702711003… No idea if these are rare, iirc it's basically a pdp-11/73 type box. Is anybody going to die and go to heaven because one is available? Must.. refrain... fromacquiring... more... stuff... spock, turn off ebay! Jeff
