name/model of HP portable printer? (not HP 2225x) circa 1993

by sieler＠allegro.com

Hi, Does anyone remember the product name or number of the tiny HP portable printer (*not* an HP 2225 of any kind!) that probably came out about the same time as the HP Omnibook 300 (1993)? (My google-fu failed me.) IIRC, it was able to print on regular paper 8.5" wide, probably using a thinkjet mechanism. Battery powered, probably black, probably HP-IL interface. I remember coveting one when I got my first Omnibook, but by that time they were off the market and the only one I ever saw wasn't for sale (I did borrow it for a few days, it worked well). The use of standard (in the U.S.) paper, plus the tiny size, had be interested in it. thanks, Stan

who collects modems?

by rsmilward＠frontier.com

If anyone has a modem made by Datec, a long-defunct manufacturer from Chapel Hill, NC, please let me know. I used to do customer support for them back in the early '80s. (They used to run ads in Byte Magazine touting their "crystal-controlled stability".) Thanks. **Richard

PDP-10 I/O notes

by dstalk＠execulink.com

For what it's worth I've posted some notes on PDP-10 I/O from a course taught by Mike Bennett at UWO in the early 1970s. The monitor at the time was likely prior to 5.06. See: http://www.execulink.com/~dstalk/pdp-10_io.pdf Don

who collects modems?

by boris＠summitclinic.com

Have a bunch of modems as well but first have to get PDP-11 stuff shipped off to those people who want it. Will see if Value Village in Kamloops will still take them. For a while they were a great place to get old electronics like the DAT SCSI drive I picked up for $5 8 years ago. "high speed" at 50 Kb/sec transfer rate which seemed fast in 2010 when I picked it up and got all my DAT backup tapes transferred to "disks" which can only run under BasiliskII now. >Clearing out stuff at my space, I have the following modems: > >NEC UltraLite-Series Image Modem Plus w/box >CTS Datacomm 2424 ADA modem w/box >Scout Plus External Data/Fax modem w/box >Digital DF03 modem > >Any offers? > >--tom

Looking for Overland TC-50M 8-bit ISA Controller drivers&software

by bvasea＠gmail.com

I have this controller, I bought it from the Netherlands three years ago with a Cipher horizontal tape drive. It was pulled from a working system but... no drivers. Does anyone have any related software for this controller? It is listed here: http://www.vcfed.org/forum/showthread.php?66915-Overland-Data-TC-50M-Pertec… I tried everything from Bitsavers. All drivers, all software. Nothing works. The board is not listed so I installed and tried everything. To give something in exchange, I wish to contribute with the full Qualstar Tapestar for Dos package to bitsavers and archive.org (separate thread).

Tapestar for DOS

by bvasea＠gmail.com

Hello I have the Qualstar Tapestar Package for DOS. It is fully working. However it requires a Microtech MCS1 "TAPE816" 16-bit ISA Pertec controller. I have the full Ms-Dos package. Where do I send the software package to be uploaded to bitsavers?

80286 Protected Mode Test

Any insight into why IBM didn't use that, but went with the (allegedly slow) keyboard hack? Noel

Wagner WAC40

by Rice43＠btinternet.com

Hi, I recently bought a core rope memory unit from a Wagner WAC40, mainly because it?s very aesthetically pleasing and looks good on display: https://i.redd.it/h9sb550uhnm61.jpg However, i can fine very little about Wagner Computer, the WAC40 (and WAC12), or the man behind the company, G?nter Wagner. Does anyone have any info on any of these subjects? This links seems to be all i can find: https://blog.hnf.de/gauner-gelder-und-computer/ Thanks, Josh Rice

Diversified Technology CAT904 80286 single board PC

by new_castle_j＠yahoo.com

I've got a Diversified Tech 286 SBC as well and was able to switch to 3.5 floppies by modifying the BIOS settings. Mine has the Dallas Real Time Clock chip and the battery was dead so the BIOS settings weren't preserved after a reboot. Fortunately I obtained a replacement chip available on ebay to fix that issue. I haven't got a manual to share, but it's a neat little board.

Once the weather warms up again - say, maybe this weekend, I'll trot off to storage, bring it back and scan it. Back in the 1970's the UW Madison CS Department's 11/20 had a 3rd party disk controller of some sort - one pack removable, one fixed, but I don't remember who made it (might have been Wangco).
