The SLM804 Laser Printer was Tramiel's attempt at a laser-for-the-masses back when a Laser Printer was a multi-thousand-dollar item. It had no on-board intelligence or memory; it used the ST's CPU/RAM. Sounds like what you have there is the controller interface. (Plugs into the ACSI port on one end and the printer on the other.) P.S., anyone want an SLM804 in need of some repair? --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

IMSAI 8080

by peacock＠simconv.com

> Yes, I wonder how many of these 'collectable' computers > are in any sense being preserved properly. I would doubt > if ROMs were ever backed up or PSUs tested. Hmm, IMSAI's didn't have ROMs (or PALs and FPGAs, programmable logic had yet to be invented), unless you added them in yourself. As for checking the power supply, an IMSAI was extremely easy to eyeball...huge transformer, diodes, and beer can size capacitors. One problem I never had with IMSAIs was in the power supply, the design was right out of Electronics 101, nothing beats a big lump of iron for simplicity. Now rust might be a problem... Actually, the only real problem I've ever found with S-100s is the bus connectors wearing out. I have an old Ithaca Intersystems DPS-1 in need of a replacement Morrow motherboard. Well, not really in a hurry to fix it, all the Ithaca boards have been in the IMSAI for the last 10 years, but I hate to throw out the DPS-1 since it had the neat front panel with the PDP style toggle switches.

Apollo again.

How nice: Both of the video cards I got are toast. One acts completely dead, the other shows a series of red vertical bars about .25" apart, with crap in between. Apparently, these were decommissioned for a reason... -------

MicroVAX 2000

by peacock＠simconv.com

> This one is a Model 625NT-AA, and comes without harddisk. It appears that there is a resistor board installed to provide a load comparable to the drive on the power supply. According to a rather sketchy spec sheet that I d/l'd from DEC, it can handle a maximum 318mb local disk. Based on the 53C80 chip installed, I presume that the drive should be SCSI. > Not exactly, the SCSI port is only for a tape drive, a TK50Z (an early ancestor to modern DLT drives). A uVAX 2000 uses MFM drives, either a Microplis 1325/DEC RD53 (70MB) or a Maxtor 2190/DEC RD54 (159MB). In order to load VMS you really need the RD54, 70MB is too small. The HD controller is the 40 pin SMC chip on the motherboard. Oddball MFM format, not compatible with WD HDCs, but the 2000 has a formatter in the ROM. The 318MB figure comes from using two RD54 drives (159 each). > At the rear of the machine are three sub-D connectors, one each 25-pin, 15-pin, and 9-pin. What are their functions? The 15 and 9 are presently encumbered by a plugin box that has three RJ45(?) connectors. Network link? > The 25 pin is the TTA2 port, RS423 (close to RS232) with full modem support (sort of). The 9 pin is TTA3:, another RS423 serial port for a local printer or terminal, but not wiored like a PC 9 pin serial. The 15 pin is for a workstation cable and carries the video (the coax connector on the little box), plus a keyboard and mouse connector (TTA0: and TTA1: serial ports). They are not RJ45s. You should also have a BNC coax connector for 10Base5 thinwire ethernet. For more info check the comp.os.vms and comp.sys.dec newsgroups, they have lots of FAQs for uVAX 2000s. I don't know the URLs but if you post a question on one of the ngs they will direct you to the web page. BTW, I might have an expansion memory board left for a uvax 2000, i'll check the old DEC scrap box. IIRC it brings one up to either 8 or 14MB of RAM. (a uVAX II maxes out at 16MB of RAM) Jack Peacock

new additions, info wanted

by g＠kurico.com

More fun stuff picked up this weekend: Canon Cat - A glorified word processor that was created by one of the original members of the Macintosh team. Mentor Graphics badged Apollo DN300 workstation. Whole box of Apple II cards and other misc stuff. Anyone have any info the the Canon Cat? Or manuals/software for the Apollo? Oh, I also have a couple of AT&T 6300 cpu's that I'll give to anyone who wants them (don't know if they work, don't have time to check them out). I also have a AT&T 3B2-310 with external expansion unit (XM something or other) for sale or trade, make me an offer I can't refuse :) BTW I'm in Austin, TX. George

Intelus/NEC laptop

by gpine＠gri.org

I recently acquired a laptop that appears to be an NEC PC-8201 with a label of a company named Intelus on the front where the PC-8201 label would be. There is also a serial number label on the back that lists the address of Intelus as in Rockville, Maryland. In addition, it has a miniature connector labeled phone on the back in place of the second SIO connector (maybe the unit has an internal modem? I haven't opened it up to check), and it has an additional small removable panel on the back that provides access to an edge-card connector on the motherboard. My machine has nothing plugged into this connector. The machine fires up showing BASIC, TELCOM, and TEXT programs in ROM, and the BASIC program even says PC-8201 Basic, verson 1.1. The machine is in all other respects (keyboard, display, battery pack, ROM access, and external connectors) identical to my PC-8201. Is anyone familiar with this machine?

Robotron is also a video game ca. 1981-2 (Williams, iirc) that was semi-unique in that it used dual joysticks -- one to control movement and one to control firing direction -- and in order to be at all successful at the game one had to be able to operate the two completely independantly of each other. Other, similar games included Sinistar (no relation, and don't even go there) and one whose name I forgot that had to do with spiders and webs. --------------------------------------------------------------------- O- Uncle Roger "There is pleasure pure in being mad roger(a)sinasohn.com that none but madmen know."

The first mass-produced calculating machine was Thomas > de Colmar's "Arithmometer" in 1820. Good point. Many early clocks were (or contained) primitive analogue computers, so I think you win there... sort of. Two books to look at: "The Mediaeval Machine" by J. Gimpel and "A History of Engineering in Classical and Mediaeval Times" by D. R. Hill. Gimpel will fill several holes in your timeline - Su Sung made quite a complicated astronomical clock in c. 1090; the middle ages saw a sizeable crop of similar machines in the west, culminating in that of Giovanni Dondi, under development from 1348 until 1364. Hill's treatment of clocks is also interesting. He points out that the Classical civilisations had (presumably inherited from the ancients) a system by which the hour changed in length depending on the date so that sunrise to sunset was always twelve hours. Thus ordinary timekeeping clocks had to combine time and date in an analogue computer to get hour-number out at the end. Some of the mechanisms Hill describes get this quite wrong! (I don't recall any of these clocks also taking account of lattitude...) OK. I'll go for the Z1 as the first _general purpose_ computer. Philip.

One of the 'Power without the Price' products from ATARI. basicly a 300 dpi Laser unit with only minimal control logic (only a bit map buffer for one (?) line of graphic. Connection to the ST computers where made via the ACSI port - ATARIs castarated version of SCSI used for the ST Harddisk. The whole font and page processing had to be done by the host computer - but the Printer was availabel for less than 2000 Mark (~1300 USD) when new - only haf the price of the cheapest 'regular' laser printer.

9 TRK Drives, Oz, Driving

by jpl15＠netcom.com

Hello List::::: I am looking for one or two 'real' DEC 9 trk tape drives w/formatter cards, in the SoCal area... TU16 and the like, and one of the small 7" reel jobs whose model number escapes me just now. I am willing to pay moderate sums for known-good-working units. Also looking for a *complete* 11/750 system... (computer, drives, tape unit, console, docs[ha!], etc.). I have a very old 11/15 to sell/trade, and several Plessey clone devices, including two CDC Caelus drives w/interface cards and engineering docs.... I can deliver in the General SoCal area. Note to Down Under Listmembers: I will be travelling to Sydney on the 2nd of July, and then caravanning to Adelaide over the space of about 10 days. It would be cool to meet some of my fellow collectors while I'm in your quadrant of the globe. E-mail me privately if there's any interest.... esp. Huw Davies, it would be fun to thank you in person for the help with my RK05 odyssey... ;} Driving: The farthest I've gone to 'rescue' PDP stuff was Los Angeles to Seattle and back in three days... 2200 miles. It was truly fun to be out on the Road away from work, phones, e-mail, faxes, memos, interruptions... thanks again to Bruce Lane for providing the excuse.. :o Oh, yeah... anyone have a Kennedy 9300 cheap/trade/free? I need some Parts...... Cheers John

Help! RA82, etc.

by kyrrin＠jps.net

OK... I've got a MicroVAX II almost ready to go. However, I'm handicapped by my lack of any documentation for the RA82 disk drive. The problem: When spun up, even when connected to the KDA50 controller, the drive gets up to speed, seeks a couple of times, and then lights 'Fault.' I'll press the 'Fault' button to try and reset. On the first press, 'Run/Stop' and 'Write Protect' flash. On the second press, it goes through its seek-and-fault cycle again. My question: Do I even have the thing wired right? Could someone familiar with this stuff describe to me which cable goes where, just to make sure I'm not hallucinating? The controller seems OK. It passes its internal and service diagnostics, and when I stare at the LEDs on the two boards long enough I can see some sort of fast scanning sequence going on about every 5-7 seconds. I can, if need be, open up the RA82 and see which internal LEDs come up. Any and all help appreciated.

Recent Commodore finds...

by foxnhare＠goldrush.com

What a surprising day, went to the Stockton Delta College Flea Market (in California) and found a couple goodies... First I bought an SX-64 keyboard and C-128 in the $1.00 section of someones space. I bought the SX keyboard cause I have a second (dead) SX without one the 128 was because I felt sorry for them having to break a 20 (also I figured if it was dead I could use its keyboard with that keyboardless 128D I have). After wandering a bit my wife shows up with a keyboardless SX-64 also from the same booth's dollar section, what a wonderful woman! (I must've missed that SX, better have my eyes checked!). Anyway $3.00 spent and get home to discover the 128 works (missing the F3 key) and the SX has some issues but seems functional (does not boot to BASIC, just a black screen, but does run carts ok, probably bad BASIC/KERNEL ROMs also keyboard connector/curcuitry needs work too.) So far I have bought 3 128s (real cheap) with the plan to use the (supposed dead 128's) keyboard on the D to discover it was not even a dead machine after all. Well Sam, (who finds many a dead Commodore 8-bit) I guess Commodore spirits aren't with you. :) Almost was tempted to buy a few of someone else's Mac problems (nice seller, he told the truth on all of em), but I figured I'd play it smart (this time). -- -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+- Larry Anderson - Sysop of Silicon Realms BBS (300-2400bd) (209) 754-1363 Visit my Commodore 8-Bit web page at: http://www.goldrush.com/~foxnhare/commodore.html -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-
