Article on old software programs (for IBM, Apple, Borland, etc)

by edick＠idcomm.com

OK, you can remove it by desoldering or whatever, but what about the distinction between the unprogrammed part, e.g. FPGA when the power's off, and when it's on and loaded? It's still hardware, isn't it? It's just different hardware when the configuration code is in it and powered, or is it? Now, what about the pseudo hard-disks sold on PCMCIA cards as "flash-disk" or whatever. Is the stuff stored there firmware or is it software? I see a change in the generalized definition of "soft" vs. "hard" in this context in a much more general sense. People talk about machine-readable copy, e.g. data on floppy disk, as "soft" copy, and they talk about purportedly fixed specifications or code segments, or definitions, as being "hard" implying they're, at least relatively, "etched in concrete," as opposed to being etched in "silly-putty" as some spec's are. It's just an observation. I was just getting comfortable referring to loadable programs/data, as one might store on rotating memory, as software, nonvolatile programs and data (Yes, tables in a code body are data.) stored in PALs, NVRAM, PROM, ROM, etc, as firmware. There's never been a question about what the stuff you see, touch, hear when it's running, and may smell when it's not, as hardware. Who knows, though. I couldn't believe it when I learned that "duhh" was in the dictionary as a word. I heard yesterday that the latest Webster has the Seinfeldism "yadda yadda yadda" as a word. <sigh> Dick -----Original Message----- From: Dwight Elvey <elvey(a)hal.com> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Thursday, August 19, 1999 10:21 AM Subject: Re: Article on old software programs (for IBM, Apple, Borland, etc) >Hi Dick > You can still grab it and remove it ( a little harder ). >It is still firmware.

IBM PS/2 P70-386 SIMM needed...+ a couple other things...

by roblwill＠usaor.net

Nope. No free slot. The long slot has an IBM 3363 controller in it, and the other slot won't accept a long cart, because it hits the cooling fan. Anyone know what the short slot's for? Yes, I do have the reverence disk. The P70 has 4 SIMM slots. ///--->>> -Jason Willgruber (roblwill(a)usaor.net) ICQ#: 1730318 <http://members.tripod.com/general_1> -----Original Message----- From: Lawrence LeMay <lemay(a)cs.umn.edu> To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> Date: Tuesday, August 10, 1999 11:33 AM Subject: Re: IBM PS/2 P70-386 SIMM needed...+ a couple other things... >> On 7 Aug 99 at 18:48, Olminkhof wrote: >> >> > >> > >> > >Basically what I meant is banks of two.

Still more PBX-wise. It's (acting like it's) alive!

by DSEAGRAV＠toad.xkl.com

Well, the power problem was easy to fix. Inside the PBX, someone had disconnected one of the live AC leads froms the screw terminal, and wrapped the end in electrical tape. Once I figured out where it went (Which was easy, it was the only unscrewed screw...) and applied power, it did all sorts of fun stuff. First, the console gets VERY confused when the things boots, and for about 30 seconds or so, the alarm goes off, all (or most of) the lights come on, and all of the various tones (intercept, dial, busy, etc.) sound at once. The tones themselved sound the same as the tones on the public network today. I was hoping for something interesting... Also, I found out the PASS and FAIL lights on the test panel are burned out. I'll have to replace them. The next thing to do is to connect some stations to it and see what happens. I think I have the proper wiring for this... Also, does anyone have the pinout of a trunk connector? You see, all we have at the destination of the PBX (Which is where I work) is Centrex service, and it sucks because we can't do PBX type stuff like music on hold, or transfer calls around, or pick up on any line from any phone... Right now when the phone rings or we have to pick up on certain phones (Cause not all of them have 4 lines, and of those that do, not all of them work.) and it's a general mess. So, what's going to be connected to this (if possible) is just 5 straight phone lines, and we'll have the Centrex service cancelled. (That way we don't have to dial 2 9s for an outside line.) SO far, from the console, I can snag a loop, and get an internal dial tone. If I dial 9 (It is touch-tone), I can get an outside line, but there's nothing on it so it's just silent. Also, I need to clean out the console buttons, right now you have to mash pretty hard to make a button go. Other than hat, I haven't been able to test much. There's no fans, and no loud noises, it just kinda sits and hums. OH, and I did (try) doing some of the test described in the DLP books, but a lot of them refrences use of a MAAP device, which is (apparently) supposed to be located in the PBX cabinet, but it isn't. The others refrence use of an "X-Ray" tape, I guess this is like XXDP to a PDP-11. But I don't have it. SO I just skipped those. Also, is there a special mailing list somewhere for people who play with old phone stuff? This is getting pretty interesting, and I really hate to keep perstering people here with this... Anyway, more tomorrow when I drag a few extensions in! -------

You built it yourself because you a) Had more time than money or b) That's the only way you could get it. I dunno about you, but I certainly fell into the 'more time than money' category (and *still* couldn't afford it). I believe his target audience has 'more money than {time | brains}'. I dunno Rich, I always figured you as a pretty smart guy. Maybe on a budget, too. Would be better just to buy the 'unique' bits, and piece one together yourself (utilizing the PSU of your choice). BTW, what's wrong with your Horizon (just curious)? > Also, Imsai-2 is vaporware. Um, until he comes up with at least bare boards and stuff, yep, fer sure. > Conclusion: although I want an IMSAI badly, I don't think > that I'm prepared to spend $1k for an out-of-the-box non-functional > machine. Ah yes, as I suspected, you're way too smart to be drawn into this 'Techno chic' marketing shtick. That's all it is: chic. This guy's just trying to 'make hay while the sun shines'. > If I were buying an "old" non-functional IMSAI, at least I could > restore it to functioning status. I wouldn't pay $1k for that one, > either. True, although this would be the way to go, assuming the price is right. Even if you just have a pile of old boards, as i said before, just get the 'unique' stuff, then fill in the gaps with off-the-shelf items. That's essentially what we did in the old days. I'm convinced that the IMSAI-2 is a product designed and marketed expressly for the purpose of becomming a 'Hot Collectable'. I'm confident in a couple of years you'll see E-Bay ads like this: RARE! IMSAI-2 Chassis, Complete! One of only 24 Made! L@@K! Anyway, more then my $0.02, but hey, there it is.

[OT] Used Exabyte wanted

by edick＠idcomm.com

I just sold my spare 8505XL, but you should have no trouble finding one for sale by searching dejanews power search using the string "SALE & EXABYTE." The software supporting these drives is so shabby that of the four major packages (of which I have all) for Windows, only one really works in the general case, and not a one works predictably. My DOS-based software works perfectly every time with it, though, as with the EXB-8200's which are more common and more poorly supported because they're SCSI-1.

No good stuff. [was Re: imsai 2]

by edick＠idcomm.com

Packaging, and packagin engineering is expensive. If you take a close look at those Packard-Bell or other US-made computers sold in the US, you'll see better packaging that what's common in home-built/assembled computers. Unfortunately, the better packaging accompanies a computer built with the necessary offsetting quality in the "guts" which is a shame.

Maybe I have a >warped idea of what this stuff costs, but I was expecting a lower number. Multiply the above numbers by a factors of 1.5 or so, and you're about in the right ballpark (though the real factor is much closer to 4 for the power supply - $50 won't buy anything but a way-too-dinky transformer.) I did a similar calculation when deciding whether I could sell my "TIMSAI" as a commercial product, and came up with a street price for it (with very similar production costs) that would have to be close to $2000-$3000 to justify the effort. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Hello, all: I had several conversations with Tom Fischer over the last few months. And I can understand the underlying premise of introducing a "new" old computer to, IMHO, capitalize on the wave of nostalgia and the desire to move down the power curve a bit. I would have no problem buying a new-old machine. I understand, though, that it's not an "as-issued" original, but a newly-manufactured unit based on original engineering drawings with some enhancements. Yes, it's not original, but, hey, it looks great from the front! I don't necessarily agree with the use of a PC power supply, but that feature makes it easy to add PC peripherals such as hard drives, floppies, or CD-R drives, should the need arise. My concern would be using legacy S100 cards on a new power buss. And this step-up regulation scheme concerns me. Why not just use a transformer from Stancor??? My other concern is cost. For $999, one gets a bullet-proof case, new terminated, large, partially-filled backplane, a snazzy front panel, and a power supply of dubious quality. No boards. Nothing. Non-functional, but pretty. And, could the "mainframe" actually cost that much?? Switches: 22@$5=$110. PS=$50. Backplane=$75. Sheetmetal=$250. FP=$100. Maybe I have a warped idea of what this stuff costs, but I was expecting a lower number. I have some old S100 cards to play around with, but I only have a non-working Northstar Horizon. So, I would be Tom's target audience. I would prefer a kit, though, since I have the skill level and interest to assemble one myself. Also, Imsai-2 is vaporware. Conclusion: although I want an IMSAI badly, I don't think that I'm prepared to spend $1k for an out-of-the-box non-functional machine. If I were buying an "old" non-functional IMSAI, at least I could restore it to functioning status. I wouldn't pay $1k for that one, either.
