Clueless Museums (was: Final Xerox Star demo)

by allisonp＠world.std.com

<I've begun to feel that anyone who got into Field Circus work after <'83 or so shouldn't be allowed any tools trickier than a screwdriver. As someone that developed service planning and service products I'd agree generally, 60% did not have the concept fo troubleshooting and were only fair board swappers. However the remaining people tended to be highly skilled with pride in their ability, most were very competent in troubleshooting. There were many I'd go to for practical expertize as the Ivory tower folk were far to isolated for my taste. Allison

Former Disk Costs (was: 32 bit Macs (was Atari hard ))

by allisonp＠world.std.com

<I've seen TeX compiled by Turbo Pascal (TeX is written in Web, which can <be converted into Pascal). IIRC it had to be split into sections to get <over the 64K code limit of TP. I still have problems with the idea of <running it _with enough space for the various variables_ in a 64K machin The conversion process and pascal compiler adds weight. <LaTeX is just a set of macros that run on top of TeX. I can assure you I <know the difference. And how early? Before TeX82? 1979. <TeX in itself has no idea what a printer is. It produces a DVI file whic <is essentially a binary file describing which characters and 'rules' <(lines) have to be put where. There's a printer driver which takes a DVI <file and outputs the code for whatever printer you have. Understood. Did a lot of work in printing for DEC and none slower than 12ppm. The DVI is essentially a bit map and as a result for godd page can be quite big. However the virtual window to disk file works and is adaquately fast. Allison

3.5 domestic sunbin 68020 1/4" tape

by akcampb＠ibm.net

Hello, I picked up a box with this Sun OS on 8 tapes. 3.5 domestic sunbin 68020 (boot format). 5 tapes 1.1 SunIPC-M sunbin 68010 (tar) 1.1 SunIPC-M sunbin 68020 (tar) SCSI3 PATCH SUNBIN 68020 (tar)--hand written on box "Do Not Install Patch with V. 3.5." At present I can not use these tapes and do not know if they work. I would *love* to score some cards for this MicroVax II (630QB-A2) that had all the cards removed before I could get to it. Perhaps someone would like to trade parts and/or knowledge for software? The tapes are in what looks like an original box and really want to find a good home. I also seem to have an extra C64, Wang PC3, and an assortment of 8-bit PC cards. Thanks Andy Campbell akcampb(a)ibm.net

Service Note: M4 Data 9914

by kyrrin＠jps.net

Although the hardware I'm mentioning is not in itself 'classic,' the technology of 9-track tape certainly is. Forgive me if this seems off-topic, but I'm trying to spare anyone else lucky enough to nab one or more M4 Data 9914 tape drives some grief. There is a potential problem spot in the early production (pre-1992, as I recall) power supply boards to watch out for with these drives. The +12 rail is supplied by an LM350 in a TO-3 case. The leads from the 350 are joined to a three-pin Molex connector that is then plugged into a matching male header on the regulator board. I've seen two failure modes in this design to date. 1). Failure of the regulator. Symptoms include initial startup OK, followed by the +12 rail dropping to about 8.4 volts after no more than three minutes. If the regulator output is examined with an O-scope, one will see an AC potential of about 1.6 MHz at nearly two volts peak-to-peak. Also of note is that the regulator gets a lot warmer than normal, as does the bridge diode module supplying the regulator's input. I've been told by M4's service department that the most common fix for this is to replace capacitor C10 on the regulator board. There is also an alternative cure, specifically replacing the LM350 with a Motorola MC78T12 in a TO-220 case (doesn't seem to be available in a TO-3). Note that it is CRITICAL to use the 78T12, not a standard 7812. The 'T' version has an output current rating of 3 amps, vs. the 1A rating of the standard 7812. The +12 rail in these drives pulls about 2A under normal operation. 2). Poor contact in the three-pin connector, which results in overheating and connector burning. I saw this in the drive I got most recently. Since I lacked a suitable replacement connector, I merely removed the male header and the burned female connector, and then soldered the wires directly to the pads. Post-1992 drives have, I'm told, a completely redesigned power supply that addresses these issues.

But did Apple license this stuff or were they clean-room type clones?
