Why not paint the darned things? I'd rather have a somewhat un- authentic finish that looked good than a cruddy yellow half-and-half case. If done right, I doubt that anyone could tell at a distance of more than 6 inches. I remember the model shop guy at Durango making his prototype cases-- out of clear polycarbonate. I thought they looked pretty nifty as they were--but then he had to go and have them painted. He made the 14" hard disk case out of sheet ABS and said he'd never do that again- -he said it was like machining rubber. All production was of high- density foam, however--and painted. In any case, paint good--plastic colorants bad. Cheers, Chuck

Token Ring Hub

> Also what is a good way to bridge Token Ring to Ethernet so > that these 486 machines can use my router/cable modem? > In today's hardware world, the easiest way to have Ethernet communicate with Token Ring is via a dual-topology router. The Cisco model 2514 with one Ethernet and one TR interface should be very affordable in the used market. If you can find older Cabletron MMACs or the chassis based Proteon equipment (70 series, etc.) you can bridge TR to Ethernet at layer 2.

Owner's manual has a date of 1997... Someone is giving one of these to me with 4 CPUs. What should I do with it? Its got no graphics, but I figure I could make it compute arbitrary precision deep Mandelbrot set zooms. -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Free Boxes (??) (Texas Instruments)

by compoobah＠valleyimplants.com

Yes, you read that right. If there is someone who wants to have an original set of boxes for a Texas Instruments Professional Computer in pretty good shape (some tape marks), I have them. The provenance on these is excellent. One owner, stored in an attached garage since 1984. Looks like System Unit, Color Monitor and (I believe) Keyboard Located in Renton, but shipping a possibility.

BASIC in the Epson HX-20

by evan＠snarc.net

Help please .... I haven't programmed in many years and I'm winging this because I don't have the HX-20 BASIC manual (it's not among the other HX-20 manuals on the Epson support site.) How do I tell my program to halt and wait for someone to press RETURN before continuing? And would I then need a follow-up command to actually make it sense the keypress? - Evan

Anyone know where to find software for an hp 16505a prototype analyzer?

by paulp132＠comcast.net

I bought one of these and the hard drive is failing. Sometimes it boots, sometimes it doesn't. If I can find the install cd and floppy, maybe I can get this working. Of course then I'd need to find a cd-rom drive that works with the 16505. Thanks, Paul

Fibre Optic Channel Extenders on Epay (Bus / Tag)

by jwstephens＠msm.umr.edu

I know there are only a couple of people interested in these, but this is probably the place to post this to get to who might want it. These units will take bus and tag in and allow one to run over a distance via fibre optic. Might be useful for a pile which includes such. hopefully the conflicting suffix numbers does not mean these do not have at least one pair that could work given the fibre optic connection.

MODCOMP II rescued...

by lbickley＠bickleywest.com

I had the good fortune of rescuing a quite clean MODCOMP II/12 today! The system has 64K of core memory, full front panel and separate I/O chassis and I/O panel. The I/O chassis contains a dual 9600 baud serial interface, a high-speed synchronous interface and a TTY controller (110-9600 baud). Does anyone on the list have schematics and/or writeups on Modcomp serial or other peripherals? If so, I'd really appreciate a pointer to the PDFs. If you don't have them in PDF form, I'll be glad to pay the cost for hard copies and shipping. Cheers, Lyle -- Lyle Bickley Bickley Consulting West Inc.
