IBM Model M2 keyboard error codes (LEDS)

by jzg22＠drexel.edu

I have an IBM model M2 here which when plugged in, the Num lock and scroll lock leds go on, and the keyboard refuses to do anything. I notice that SOMETIMES the Model M I have here does the same thing (num+scroll on, no response) for a few seconds, and I'm GUESSING it might be something like the 5v line can't supply enough current to run it properly at startup, but it usually starts working after about 3 or 4 seconds; the M2 does not. Any idea what causes this, or whether it is fixable? Jonathan Gevaryahu jzg22 at drexel.edu

Latest rescue...

by mdavidson1963＠gmail.com

Ok, I found it on EBay, but I consider it a rescue. :) This is an HP 9836 Model 200, a machine I've been looking to find for quite some time. It's a Motorola 68k-based workstation that was targeted (I believe) at the scientific market. It runs a proprietary OS and has several languages available for it. My next goal is to try and generate diskettes for it, which is not going to be easy until I finish getting my IBM PC set up for use at home. There's more information available at http://www.hpmuseum.net/display_item.php?hw=3 and I have a photo posted at http://www.facebook.com/photo.php?pid=4243664&l=a9af6169d9&id=734972117 I don't know if anyone would be interested in something like this, but the seller has several more of these (they were apparently in a warehouse he was asked to liquidate) and he's had some trouble finding buyers. The biggest issue is shipping them. This is an 85 pound machine and it cost about $80 to ship it to me UPS Ground (I didn't get the chance to ask him to use a different shipper). If anyone is interested in one, I can collect email addresses and send them to him. I believe he is willing to let each one go for $25 plus shipping. Mark Davidson mdavidson1963 at gmail.com

Heading to the recycler

by frebird2＠swbell.net

I have (2) Black Box Modular Statistical Stat-24 Multiplexer's (MX868A) that are destined for the recycler at the end of this week unless someone on this list wants them. I may be able to locate line drivers that can be used with these units as well. Please contact me off list if you are interested in them.

Pretty sure that's a stock/Googled photo. I think I've even seen it before. If it's real, whoever gets it might check the recent archives as I recall someone looking for the 1U "DEC Datasystem" strip.

A Hackintosh ... in 1986

As long as they're totally cool. You need an Outbound Laptop Model 125 from 1989. It was totally cool. It weighed about 9 lbs, which was still lighter than the Macintosh Portable, had a detachable IR keyboard with pointing device. The pointing device was an isobar which rolls for up and down movement and slides side to side for left right. In addition to the normal four SIMM sockets for 4 MB of system RAM, there were four SIMM sockets for persistent RAM Disk (called a Silicon Disk by Outbound) which could be up to 16 MB with four 4MB SIMMs (one of these days I'll try 16 MB SIMMs in there). The CPU was a 15 MHz 68000 and it used either SE or Plus ROMs. The screen was 640 X 400 LCD. It used a standard camcorder battery. One could have either an internal floppy drive or an internal 2.5" IDE drive of 20, 40, 60 or 80 MB capacity. However, this creates the biggest conundrum for the collector. If you get one with the internal hard drive, you have no floppy drive unless you get the external floppy drive with it. Many of these machines have been separated from their peripherals over the years. And the floppy was not "standard". It was a standard Citizen brand floppy mechanism, but it had a controller card on the back end with a security protected GAL included. Sigh. As well as a 37C65, a WD92C32, a small Atmel EEPROM (28C64) and a Xicor X9103 (digital pot.). It was possible to dock the Laptop to the (now ROMless) SE or Plus (if one had a docking card installed in the ROM sockets) and then use the I/O ports, screen and memory of the ROM-less host computer. So one could have dual screen operation. The Outbound could also be put in Target Disk mode when using the SCSI adapter so that the internal IDE drive would appear as a SCSI disk to a connected host machine. Or the SCSI adapter could just be used to connect to SCSI peripherals. Standard Macintosh Serial ports were included with support for LocalTalk, so if you lack an external floppy drive, file transfer via LocalTalk/AppleTalk is still possible. There were other cool features and much thoughtfulness in the design, such as a cable to connect the keyboard if one was operating in an environment where the IR wouldn't work (bright sunlight?). And a Bus Mouse port on the keyboard so one could use a mouse instead of the Isopoint device. I wish I could track down Doug Schwartz who owned/started Outbound. I'd really like the code for the GALs in the floppy adapter and the SCSI adapter (assuming he still has them). And if he has the source for the laptop EEPROMs (there was a little code in additional EEPROMs in the laptop to handle various details) that would be nice. They were based in Boulder, CO. Anyway, as far as cool Mac clones, in my opinion, the Laptop Model 125 was the coolest. Outbound later made some nicer Notebook computers with lower weights and more traditional form factors, but the Laptop Model 125 takes the cake for cool features at a very early date. The clones of the mid-to-late 90s were (mostly) just Apple chip sets (and often entire Apple logic boards) wedded with different power supplies and computer cases. When you dig into the actual feature sets, they didn't offer anything you couldn't already get from Apple, except that one clone that had the standard set of PC ports... The Laptop 125, it had innovative stuff that didn't come from Apple. Jeff Walther

old Sun SCSI chips

Yes, the 53C96 supported *unenhanced* SCSI 2 operations, meaning 5 MB/s maximum theoretical transfer speed. If you wanted *Fast* SCSI-2 (10 MB/s) you needed the 53CF96. I do not know anything about the FAS101. Jeff Walther

Tektronix 4014's found - and IBM 523 -heads up. - here's where

by eccm＠swbell.net

heads up on Tektronix 4014's In the "Black Hole", Los Alamos, NM, the 19" Tektronic 4014? terminals - -someone needs to save these. One has a busted CRT, other looks OK, and is a rebranded TEK unit apparently. Yes, outdoors, but nothing rusts there! Whomever gets them and gets one working, there is a small community that admires them greatly so it's not like anyone would be "stuck" with it. images here: http://www.bunkerofdoom.com/travel/blackhole/1009125.jpg http://www.bunkerofdoom.com/travel/blackhole/1009128.jpg also an IBM 523 summary card punch was inside, in the back. I suppose if you need to summarily punch a card, this is the machine for you. looked dusty but OK. Patrick

The greenie movement is a religion, not a sensible movement attempting to solve problems in rational ways. If they were the latter, they would have been advocating nuclear power as soon as reducing CO2 became a fad. CO2 emissions have been a concern since the late 70s if not earlier, but that didn't stop the greenies from lying about nuclear power at every opportunity and essentially forcing the increased use of coal. If the USA had built 10 new nuclear electricity generating plants a year since 1980, our CO2 emissions would be 28% lower now, not to mention the accumulated reduction in emissions over the last thirty years. Arguably, the greenies caused global warming.... Jeff Walther
