Uncompress the files going on the first tape, write the second tape with the compressed files as you downloaded them. MS

You can install Ultrix over Ethernet from a running Ultrix server, but don't ask me how. MS

A plea to classiccmpers

by Edward.Tillman＠valero.com

The going rates for businesses in our area (south Texas, using Southwestern Bell) is to bill by the minute, with start/stop time and ring-time measured and billed in 6-second increments. If your party answers before the 3rd ring, there's no ring charge. It they answer between the 2nd & 4th ring, there's a 6-second charge. If they answer after the 4th ring, there's a full minute charge. The main portion of the call is billed by the minute, with your final minute being charged in 6-second increments. Southwestern Bell has a near monopoly here, but the competition (after their lure-in, loss-leader specials) is worse, since the also have to pay Southwestern Bell to use the same trunk lines... -sigh- Ed Tillman edward.tillman(a)valero.com <mailto:edward.tillman@valero.com> > -----Original Message----- > From: cctalk-admin@classiccmp.org@PEUSA On Behalf Of chris > <cb(a)mythtech.net> > Sent: Wednesday, January 22, 2003 1:05 PM > To: Classic Computer > Subject: Re: A plea to classiccmpers > > >Pay by the minute for connection time?

Mr Tillmans - CD History Inquiry

by truthanl＠oclc.org

Regarding the History of data CDs... I did some research. OCLC Online Computer Library Center, Inc. was adapting this technology back in 1985-86. Specifically we were interested in multiple player stacks or jukeboxes for collections of database disks. Phillips, Hitachi, and Sony, were the first drives out. @ $900 - $1000 each Phillips had a proprietary interface card for the PC bus that could support two external drives. Hitachi had a card out that supported multiple configurable I/O Bus Addresses and a parallel bus structure that could support up to 4 external drives off a single interface card. (OCLC selected Hitachi) Each manufacturer also had SCSI cards that could support multiple drives. The big thing was the MSCDEX extensions supporting manufacturer dependent device drivers with their "switches" enabling multiple drives. Once the High Sierra Data format was adopted in 1985, and the MSCDEX extensions were widely distributed, CD Drives became more common. Price fell to $550-$600 ( Later MSCDEX distribution was tied to DOS Version / upgrade distribution ) After Windows 3.X software distribution consumed the worlds diskette production capacity, AT class machines began shipping with CD Drives installed.($110 price point) Here is a (google recovered) link that shows a partial reconstructed history of CD data adaptation: http://www.itc.nl/~bakker/info/rs-data/cd-family.html Sincerely Larry Truthan

Any Cromemco USERS?

by mhstein＠canada.com

------------------Original Message-------------- From: "Bill Sudbrink" <wh.sudbrink(a)verizon.net> To: <cctalk(a)classiccmp.org> Subject: RE: Any Cromemco USERS? Date: Wed, 22 Jan 2003 09:51:34 -0500 Reply-To: cctalk(a)classiccmp.org <snippage> > I'd be interested in knowing how you got CP/M onto the Cromix > diskettes and configured for its memory model? The hard way (and the fun way)! I wrote my own CBIOS, bootstrap, and a program to format a diskette, cross-compiled on a modern intel box, wrote a program to massage the compiler output into a text stream that the ROM monitor on the 16FDC would like and then used the monitor to run the formatter. Finally, pumped over the bootstrap, CP/M and my CBIOS and used the sector write facility of the 16FDC ROM to write the whole thing to a diskette a sector at a time. It was very gratifying when the sucker booted up the first time. MS: !!!!!! Very gratifying indeed, I'll bet!!! Wow - that's REALLY doing it the hard way, but maybe it was the only way...! How long did that take? ----------------------------------------- > TM100 drive(s) I assume? Actually, a pair of SA-851s. MS: Ah yes, you did say Imsai chassis, not Cromemco... ------------------------------------------ Something about the 16FDC doesn't play nice with the IMSAI front panel. You can't deposit or examine memory with it on the bus. Even with the schematics, I don't see what the problem is. Do you know a solution by any chance? MS: Afraid not, the Cromemcos I worked with were all essentially stock. Someone else asked me about that a while back; apparently there is a document somewhere talking about using a 16FDC with a front panel. I assume you have the complete manual, esp. PP 64-65, and have set the switches to map out the RDOS ROM? I wouldn't think the interrupt chain or the serial port have anything to do with it, but if your front panel uses I/O ports, I don't think they can easily be disabled on the FDC. Sorry, wish I could help. mike

What's better than canned air?

by cb＠mythtech.net

>Discuss, please. What do *you* use instead of consumer canned air? I bought a small air storage tank at Sears. Its a 12 gallon tank or something like that. I think it was about $40. At first I filled my tank at my fire house off our breathing air compressor, but that got to be a pain, so I bought a small air compressor (also at Sears, also about $40) The tank is good to about 200 PSI, and comes with a regulator assembly and hose. The compressor is good to 250 PSI so it fills it nicely. I added a coiled hose and blow gun attachment, and the system works quite well. The compressor is a tad loud, so sometimes I walk away and close my office door when it is filling (the tank does NOT have a blow off valve, so I can't walk away for too long or I risk overfilling, so mostly I just go deaf when it fills). The only things I don't like are it doesn't last very long. So I find I have to refill more often than I would like. Part of the rapid loss of air is because one of my connections isn't air tight, so if I leave the tank turned on, it slowly bleeds itself (it will go empty over night), but in general, a 12 gallon tank just doesn't last long (way longer than canned air however). Eventually I will replace it with a regular tank/compressor unit, but I'm not in any rush. Also, make sure you use some kind of a regulator so you can adjust pressure as needed. The first time I used mine, I had the pressure up to about 80 PSI and I went to blow the dust out of a floppy drive... I watched the drive head rip clean off and shoot out the other side and across the room. But the drive was real clean! I generally keep mine at about 15 to 20 PSI for most work, going up to about 40 if I am going after really encrusted dirt and dust on things that are sturdy (like a power supply fan). And the other major downside to all this... that dust has to go somewhere... so my work bench now has to get regular scrubbing to remove the crap that has gone airborne and resettled (and I'm afraid of what all winds up in my lungs). Because of this, I have tried to move to a vaccum for much of the initial dirt pickup, and switch to the air for the final details. -chris <http://www.mythtech.net>

Ultrix v4.3 install on mVaxII

by franco.tassone＠inwind.it

Hi all, I own two mVax, a mVax3100 and an mVaxII, the first one equipped with cdrom and tz30, the second with a tk50. I've installed Ultrix v4.3 on the mVax3100 from the cdrom distribution, and would like to install it also on the mVaxII, obviously no cd on it. Is there an alternative way to install it on the mVaxII ? Thanks in advance.

Seeking manual for the Jupiter 4000

by kurtk7＠visi.com

I recently came by a Jupiter 4000 and am in need of a manual. If anyone might have one that I could get a copy of, I would appreciate it. Oh, this is my first posting. Strange, but I remember the Classiccmp having a nicer website recently, at least a front end, and it appears to have disappeared. (If I have error'd in my posting protocols despite the FAQ, please let me know.) Thanks Kurt
