Tektronix CT8500 terminal -- is it an OEM'ed Tek 4024?

by legalize＠xmission.com

One of the items I pulled out of the Black Hole this weekend was a Tektronix CT8500 terminal. It goes with their 85x0 microprocessor development systems that we've talked about here over the past year. I also snarfed the operator's manual for it, so that will appear on bitsavers soon. Bitsavers has the user's guide for the CT8100 terminal which is really a 4023 as is blatantly obvious from reading the manual. However, the operator's guide to the CT8500 doesn't make mention of any other Tektronix terminal model. On Wednesday, I'll open the cabinet and inspect the board set inside, but until then I thought someone here might be able to shed more light on this. -- "The Direct3D Graphics Pipeline" free book <http://tinyurl.com/d3d-pipeline> The Computer Graphics Museum <http://computergraphicsmuseum.org> The Terminals Wiki <http://terminals.classiccmp.org> Legalize Adulthood!

EISA Configuration Utility and .CFG files

The challenge with EISA is finding the .CFG files that work with the EISA Configuration Utility so you can get the mainboard to work with the boards. The floppy-based sets I have come across are a superset of those needed for a specific board so it is usually worth digging around in manufacturer "driver"/mainboard diskettes to check if they also shipped .CFG files for boards other than their own. The .CFG files (they are text files sometimes with comments) can be a useful source of information about what the board does and how it is intended to work (like slot-specific assignment, IRQ conflicts etc).

Microwave sink (was: Re: strange remark about your collection?)

This may not be the best idea, unless your water is "dirty" (in the sense of having something suspended that forms nucleation sites for steam bubbles). Our water is "clean", and my wife once decided to try to heat some up in our microwave. It superheated by a noticeable amount, then finally boiled off catastrophically. Big cloud of steam, microwave door blown open, loud noise, 100 C water splashing around the kitchen. There was some damage apparent later in the switch that should normally turn the thing off when the door is open, which I eventually had to replace, but otherwise the microwave itself was OK. Maybe this is an unusual event and almost certainly it depends on what container the water is in, but I'd use a little caution with that approach given our experience. Howzabout a pile of CD's or marshmallows or a crate of eggs in there instead? ;-) OK seriously, wet towel or wheel of cheese in a bowl or something that won't superheat and has not much mechanical integrity?

Texas Instruments 960B

> does anybody have bits for the TI 960B (not 960A) minicomputer, e.g. > software, schematics etc. ? I have some additional material on the 960 that isn't up yet on bitsavers. The 960 and 980 share some peripheral interfaces. Did you end up with the 990 system as well?

NOS IC and vintage brds available

by shumaker＠att.net

Info links for someone looking to move some ICs and circuit boards without doing the EPAY thing. He dickers! This stuff was posted here a while back as images but I suggested he build a list. I acquired a couple of the boards and had no issues in dealing with him. No other interest except to pass on the info. YMMV!

HP 7580B A0 plotter has to go

by hp-fix＠xs4all.nl

I've a HP 7580A A0 plotter which has to go, I need the space for a HP 1000 rack and it's to huge to put in the attic. I'm open for offers, any reasonable offer will do, if no one wants it I'll scrap it for parts. This includes pens manuals and other add-ons. I'm located in the Netherlands near Groningen. -Rik

Monsanto IC datasheet request

by wdonzelli＠gmail.com

I found some strange ICs from Monsanto. They are type MQL105, in original Monsanto packaging. I can find no datasheets on the net (one site mentions the chip, but says scans would be "difficult"). Oddly, the datecodes on the chips have been erased at the factory. -- Will
