Panasonic Exec. Partner information wanted

by Marty＠itgonline.com

I was just given a Panasonic Exec. Partner. It looks like a laptop on stearoids. It should have been called a lugtop. It has a red plasma display, full keyboard, twin 5 1/4" floppy drives and a built-in printer. It comes with a convenient folding handle that swings out of the way (so as to not destroy its sleek lines presumeably) and boots fine. Unfortunately no paper came with it so I'd appreciate any information on when this was marketed. It's PC DOS compatible so that dates it post 1981 at least. Marty Mintzell

Modern Minimalism (Was: Future Computing Trends)

What could be more retro than building the ability to port >CP/M to anything with a C compiler? Darn, I had this idea, too. I was going to port it to the Palm Pilot. I looked at the code, and discovered a few things that the owner of that page (Tim Olmstead) hadn't found. I think CP/M-68K was cross-compiled under Alcyon C on a VAX 11/780. (Alcyon also produced an OS called Regulus that was available for Smoke Signal Broadcasting's 68000 systems.) The source contains the name "Tom Saulpaugh", and a web search turned up a book "The JavaOS? Design and Architecture" he wrote. He's at Sun as the architect of JavaOS for Network Computers. Tom Mason also works at Sun, and he worked at DRI on CPM-86, Concurrent CPM-86, and CP/M-86+. Novell appears willing to release source, but Tim suspects that there's no one around willing to discover or document what's available - if anything. For example, the source to CBASIC should be around, but they haven't released it. - John Jefferson Computer Museum <http://www.threedee.com/jcm>

Found a decent use for a PC...

<No, it's just something about REALLY LARGE frontpanel boxes that rules. <The KA-10 is plain awesome. It's not only a real good hack, but it's <the foundation of timesharing and the ARPAnet. I'll probably never see o <in action, so I'm amassing as much information as I can - maybe it can b I have and it's more than awesome. <re-built? Who knows, they used discrete components... Half the problem is finding one that is complete enough with minimim peripherals. The peripherals also eat power. just the cpu with a hack to use modern disks for power and space savings wouldn't be out of line. As to being discrete, the answer is mostly not completely. It's a hackable machine. <Of course, this is WAY out of my league, but if I keep docs around... You never know. Allison

BBC Model B - video help

by Philip.Belben＠powertech.co.uk

On the subject of BBC video problems, it occurs to me that the BBC micro does scrolling by moving the pointer to the start of the screen (under some conditions?). If you can get it to do this, and see how the display behaves, you may be able to determine easily if it's an addressing problem. Just a thought. Philip.

Not to go too much off topic, but I made the russia comment, because I was born in the USSR, and it is very apparent to me. They DO use rubles, but before they artificially deflated it (with a clone case :), the xchng rate was something like 5000 Rubles to a US Dollar. I was watching a Russian comedy program a few days ago, and they mentioned that Russia has more dollars than the US, discussing the aid US gives them :) Actually, dollars are pretty much common there now, with slightly greater value. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com

To be strictly accurate, all 3090 models of which I am aware are water cooled machines. I was a student when I worked at IBM - a year before going to university, and two summer vacations - after which I somewhat lost touch with them. My last job with IBM was in 1988, and not at the marketing location where I had worked before, but in a factory building cash dispensers. My last real knowledge of IBM was >from 1987, then. >> involved!) to replace the strange 400Hz thingies.

Ouch! But you may get away with providing a fake "ac good" signal, rather than ac for it to monitor. > The "Mill" was chopped up into smaller rooms - our room just happens not > to have mice power, but the one next door does. Strange - I shouldn't have thought it took much to power a mouse :-) Still, this means you shouldn't have much difficulty with the upgrade. Philip.
