Icom Attache: What is it?

by netsurfer_x1＠hotmail.com

I was doing a little snooping a while back & I came across a computer called the Icom Attache. It sounded like an intresting computer, unfortunately, I can't find anything about it! What is it? Is it an OEM-ed Otrona Attache, a regular PC-Compatible laptop, or is it something completely different? ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

Compact QBus Systems (Was re: Los Angeles: Commodore PET 8032's...)

by allisonp＠world.std.com

<The H780 supply is about 3 inches wide IIRC and mounts beside the card cage <That would make it a couple inches wider than the TU58EX. <Dan More like 5" when you add casing. I have a 780+backplane. The Rackmount BA11-M is 3.5h x 19w x 18.5d (the depth is possibly inaccurate) The destop version is a little larger for prettyness. The BA11-VA 3.5h x 13w x 13.5d the H780 ps alone 5.5"W3.3hx14.625L The BA11M however will take a lot more cards though but is very noisy. Allison

The C programming language

This may well be true, but C programmers are not the only offenders. The worst period of my career was converting COBOL gorilla-code to C. The unstructured, uncommented COBOL code was in some cases so indecipherable that I simply dug out the original spec and threw the COBOL away. Unfortunately, this wasn't always possible . . . I myself heavily comment my C code, since I have to maintain it and can't always rely on my failing memory ;>) Glen Goodwin 0/0

Dayton Computerfest finds

by ethan_dicks＠yahoo.com

At the Hara Arena in Dayton, there are three events per year that relate to this list: the Hamfest in May and the Computerfest in March and August. I only went Sunday this year as opposed to my traditional Saturday. Since I didn't go for modern PC parts, I found the selection to be sparser than ever. Scattered throughout the back rooms there were the piles of $3 to $5 boards of various vintages. I did manage to get a pair of DEC-Tulip-chipset 10/100 cards for $3 each and a wad of Microchannel boards (Ethernet and SCSI) for someone else in a $15 "all you can stuff bag". Besides a few cards, the only interesting thing I picked up was an Apple QuickTake 150 digital camera with external battery pack and PSU for $35. One drawback: it came with a PC cable (DIN-8 to DE-9) and I only have the Mac software. The Mac cable is typically grey with an icon molded into both ends of a pair of arrows pointing opposite directions and a stretched "S" line between them indicating that it's a crossover cable. I do have the pinouts for the camera, but if I were to make a cable, I'm not sure what all the matchups are for RS-422. The Apple Technote pages show how to make a PC cable, but that's the one I already have. So... does anyone out there have a Mac "null-modem" cable they'd like to get rid of? Alternately, does anyone have the PC software? It's for Win3.1, but at least I'd be able to dump the camera.

Made the Paper

by jrkeys＠concentric.net

The local Saint Paul Pioneer Press is running a story about my computer collection in this Monday's Tech Section of the paper. I spent two parts of two days with the reporter and another day getting my picture taken with a few items from the collection. I will try and scan it in and put it on my web site as soon as I get it up. Had a very good weekend and will writing up my finds on Monday.

Don't forget to check the manufacturers when you need docs!

by xds_sigma7＠hotmail.com

Hi, Well for what it's worth, IBM still offers a bunch of random ancient manuals through the POS (publication ordering system), at http://www.elink.ibmlink.ibm.com/public/applications/publications/cgibin/pb… That's one nasty address, isn't it? ;p Anyway, I was searching around in there, and among other things, I ordered "IBM 360 model 67 functional characteristics" (GA27-2719). I'm going to call other vendors when I have time, I wanna see if I can get some 470 manuals from Amdahl, for instance. Unfortunately, I can't find the rest of the docs I need for my 8100's or for DPPX/SP, odd that I can't get manuals less than 20 years old but can get 360 manuals... Also, I know this will interest some of the list; assorted card punch manuals are available too.
