There is some hidden wisdom here! There are several plastics used for making foam. One of these is polyurethane, others are polypropylene and polyethylene. I have often thought that manufacturers who put high valued goods in polyurethane should be responsible for the repairs even after 30 years; this stuff is often terrible, turning to either dust or paste, neither of which is good for a camera or a computer. The paste variety is very hard to completely remove. Conversely, those camping mats can be made of PP or PE, which I have never seen undergoing the transformation into a viscous liquid. You computer should still be clean after you pass it on to the next generation.

The hard case is the Radio Shack > original-issue hard case, so the foam is a pretty big size. A tip I got from Amateur Photographer magazine, relating to foam for camera cases, was to use a camper's sleeping mat. They're fairly hard foam, about 1cm thick, and are larger than any carrying case I've ever seen :-). And they're not too expensive. Dunno if this would work for the M100 case, but it might be worth a try. -tony .

Kaypro II's available

by doc＠mdrconsult.com

Was at the local thrift tonight and there are 4 apparently intact Kaypro II units there. They want $20 each, and do not dicker. I'd be willing to schlep them and ship them for a modest honorarium. I don't know anything at all about Kaypros, and really don't care to learn, so ALL I'll check for is huge dings in the box, obviously hosed keyboards, and cracked screen. The thrift doesn't allow testing, either. Reply off-list, please. Doc

VAXstation SCSI question

by jpl15＠panix.com

On the back of the VS 3100 is a DEC SCSI connector that I would like to be able to adapt to a 'normal' SCSI I cable (Amphenol Blue Ribbon connector). The 2nd choice would be to connect to once of the spare cables inside the box... Anyone have any info on an available adapter for this? Googling didn't help much... Long shot: was there ever a Pertec formatter made for the VAXstations? Or SMD interface? Just curious... Cheers John

pdp problems

by dan_williams＠ntlworld.com

I am having problems with the pdp 11/04 I picked up last week. If I power on with the machine without the extra cards, I get output on the la36 with a $ prompt. So far so good. But with the card cage connected the run light is permenantly on (ie. with halt switched), with no output.on anything (There are two rs232, la36 and a display unit) So the main questions are : what could cause this ?. The main cpu box has a 7856 which the la36 is connected to, also a 7800 which has an rs232 cable connected to it, how do I get the console output to this so I can use vtserver on it ? The controller card for the rx01 is in the extra card box, In the short term can this be moved to the main box ? It has a dead rk11-d and an untested rk11-c with no power supply unit and no case. What sort of power supply runs this, I also picked up about 5 different power supplies with this, so one of these might do the trick. Thanks for any help Dan

LEDs Was: Re: Emulation (Was: Emulators of Classic

by india_50＠yahoo.com

well, of course, they wouldn't be cheap to produce on a wafer like other chips. Also, i don't think it is feasible as such will not be able to handle all the power that would be o/p(heat i mean), which would be in Watts!!(too high for ICs) therefore i don't think it is possible to get led's for the 75dpi screen ________________________________________________________________________ Yahoo!

TI99/4a and expansion chassis

by ghldbrd＠ccp.com

Just found the expansion chassis at a hamfest for $1, and wondering if there is any documentation online for it. I'd like to try to see if I can save some programs, etc. It has the bus interface card, floppy controller, RS232 adapter, and the 32k memory module too. Any of you TI fans out there please contact me off-list. Gary Hildebrand St. Joseph, MO

PDP-11 disassembler

Would folks here be interested in that? Not to disencourage you, but there are already several in the DECUS library. Mostly written in MACRO-11 admittedly... I usually use DOB on Magica.
