I have come upon the mother of all Microchannel cards and now have in my ownership a completely maxed IrisVision card with the driver discs, cables and the technical reference manual. You would not believe how hard it was to get hold of this thing. While I already have a Microchannel system, a 55SX, it's running AIX 1.3 and it's not worth it putting this card into that. What I want to drop it and a few other nice cards I have collected like MCA sound and GPIB is something like a Model 95 but for some reason I have terrible luck with them. With the first one the deal went as far as paying for shipping before the guy reconsidered, refunded me and recycled it. The other system and a half that another collector had I almost got last month was working several years ago and was as maxed as you could possibly get but was put into a garage and over time due to poor placement and clueless relatives, both systems were first written off my the harsh pacific coast air and then thrown away because they looked to be worthless prior to them moving. I'm still on the hunt for one and got all the extras I would ever need like the Type 3 complex with an upgraded 5x86 processor, the reference manual and diskette and a few other accessories like an internal CD drive and recently I came across a 10/100 Microchannel card but still the 95 eludes me. Why are these systems so remarkably hard to find when you need them? I know someone who recycled about a dozen five months ago but of course, he didn't know I needed one. :P

yet another pdp-8 in a fpga, but this time running tss/8

by brad＠heeltoe.com

I know it's crazy, but I finally got my FPGA based PDP-8/I to boot TSS/8. http://colo3.heeltoe.com/download/pdp8/README.html It's been sort of working for a while but had some odd bugs. I did a lot of simulation and comparison with simh. I think it's pretty close to correct now. There are still a few bugs to clean up but it seems to run everything correctly and save files to the disk. I hope to agument my "disk maker" to extract and rebuild tss/8 file systems soon. It would be nice to build up disks from some of the decus programs. Right now it will extract and replace the main parts of TSS/8 but not the file system itself. -brad -- Brad Parker Heeltoe Consulting +1-781-483-3101 http://www.heeltoe.com

Asante EN/SC SCSI to Ethernet adapter

by healyzh＠aracnet.com

I know these were made for early Mac's, I have used one on my Mac SE/30. In the years since I lost mine in storage I've seen information about using them on other classic hardware. ISTR that at a minimum people have used them on Atari TOS systems. I finally found mine last night while working some more on the garage. Does anyone know what non-Mac systems these can be used on? Now to find the powersupply, that's with the Ethertalk to Localtalk converter I no longer use, as I've switched to an HP Jetdirect box. Zane -- | Zane H.

Looking for manual to a SD 20/24 PAL Programmer

by ragooman＠comcast.net

I found this at Breezeshooter's Hamfest last wknd in the Pittsburgh area. This is a PAL programmer made by Structured Design, SD 30/24 It even includes a Stringy Floppy cassette player, plus a spare cassette--I hope I can find these too. This is supposed to be a standalone programmer with just a serial port for console input and display. Would someone know where I can find a manual for this PAL Programmer ?

Bitsavers upstream?

by hachti＠hachti.de

Hi folks, as some of you might know I'm dealing with quite a lot of documentation in paper form. From time to time I scan some docs that cannot yet be found on the web (i.e. Al's bitsavers.org). A few month ago I posted some notifications about having uploaded stuff to a temporary folder on my website. But I have no clue if it has been taken by anyone or Al Kossow. This feels a bit complicated to me. So I'd like to suggest some possibility to upload stuff to bitsavers directly. Or to a special "incoming" folder or something like that. I'd like to have an easy and reliable way to offload my stuff. Without writing emails, asking for acknowledge and all that hassle. For me personally having some kind of access via scp would be perfect. Some people might prefer ftp/sftp. I could have written this in a private email to Al but I assume that it might be sensible to have some kind of discussion around the topic. Hope you're all fine! Kind regards, Philipp

Hi folks, does anybody have a reasonable electronic form of the unit number stickers used on RK05 disk drives? I want to renumber some drives but don't have the numbers.

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

A Hackintosh ... in 1986

by trag＠io.com

> Date: Sun, 6 Jun 2010 16:12:47 -0700 (PDT) > From: Chris M <chrism3667 at yahoo.com> > Somewhat offtopic, but if anyone in the northeastern part of the US has > any totally cool PowerMac clones (Radius, Moto, etc.), I might be > interested. 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

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.

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

Authenticity opinions

by shoppa＠trailing-edge.com

Probably the lowest effort option also makes the fewest changes to the original: A small external "boost" autotransformer to give maybe 10 or 15% extra headroom. This could be done without using a big transformer. What you do is use a say 20VAC 3A transformer secondary in series with the primary, wired to that you end up with 140VAC with 120VAC in. This can use a physically much smaller transformer than a 140VAC 3A isolation transformer. I'm guessing the AC current at the input to the power supply is circa a very few amps or so (why I suggest a 20VAC 3A unit above). Tim.

JetDirect problems

by brianlanning＠gmail.com

I tried to attach a LaserJet III to a JetDirect EX Plus. The printer looks like it's ok. It can print a test page from the control panel just fine. I haven't tried to attach it to a computer parallel port yet, so I haven't ruled out the parallel port on the printer and cable yet. I installed the HP TCP/IP driver for vista. It finds the JetDirect box just fine. I can see in the router logs that the JetDirect asks for and receives an IP Address. Vista lets me create a printer using the TCP/IP "port". When I go to print a test page, nothing happens. It just says "error" in the printer window. I can see the network light flashing on the JetDirect. But nothing happens. Can anyone suggest something else to try? brian

hacking early monitors

by chrism3667＠yahoo.com

I blew one of the biggest deals of my life a while back. A barely used *color* NCR PC4i. And free to boot. It had a horrible death. Well I do have a few green screened PC4s. Would like to swap out the monitor section. Came across a Samsung EGA monitor. The PC4i had 400 lines of resolution, the EGA 350. I've been told in some circles it was common to display that sort of video on something *close*. Are there inherent dangers (x-rays, etc.)? Do you abnormally shorten the lifespan of the monitor by doing that?

OT; Vintage TV's to be rescued

by ragooman＠comcast.net

I'm not sure if I mentioned it here but I have some photos from the office building that I was talking about 2 wks ago. There's more rooms of this, some are mostly 70's stuff, there's 4 floors of stuff here - all jam packed. But the other problem is getting a bigger flashlight as there's no electric in the building. They only have one floor being lighted at a time with a generator as they clean it out.. It's slow going as they only spend 1 or 2 times a week to cleanup the place. But I can reserve any TV's if they know someone is going to pick them up. My buddy's shop is running out of space, so there's little chance of storing any more TV's for a future pickup/delivery. This place is located in Pittsburgh,PA. I plan to get some more photos next wknd of any interesting TV's. http://picasaweb.google.com/ragooman/VintageTVRescuePittsburgh2010 =Dan -- http://www.vintagecomputer.net/ragooman/

I've got a DataFlyer 500 expansion for my Amiga 500 and it's dead as a post. There's +5 on the connector but no where else that I can find on the board. Does anyone here happen to have a schematic for it or know where I can find one? tnx. g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.simpits.org/geneb - The Me-109F/X Project ScarletDME - The red hot Data Management Environment A Multi-Value database for the masses, not the classes. http://www.scarletdme.org - Get it _today_!

No - it is ham lore only. Many tubes lives will shorten if the filament is run below spec. In some types, life will drastically drop. -- Will

Lightbulb police? (was RE: Anyone off to VCF-UK)

by marvin＠west.net

I am impressed. This thread has managed to go on and on without any classic computer related information. And it has also gone through a number of topic changes in the process. I think this one sets a new (unfortunate) record for OT discussions :(.

OT Postings

by marvin＠west.net

The problem with the delete key being a "solution" is that a number of people who can and have contributed to the list appear to have left. Having been through this more than once, the problem comes with people who actually want to discuss and read about classic computers. Remember the cctech (I think that is right) list that was created in an attempt to only contain ontopic posts? Hijacking a listserver is not a good thing ... unless the object is to drive away these people who are actually interested in classic computers!

looking for a small front cover (DEC rack)

by henk.gooijen＠hotmail.com

Hi, I know it's a long shot, but you never know ... Browsing the eBay auctions, I saw the 11/03 DataSystem 11/03 auction 390194753263. I have been looking for some time for the small front cover with the text "DECDatasystem" on it, like the one in the picture between the processor box and the top RL02. The cover is 2 pieces, the plastic part that you see and a metal bracket which mounts on the rack with 2 screws. Does somebody have this small cover (what's the correct word?) and is willing to sell it? Shipping costs (to The Netherlands) is not a problem. Contact me off-list ! BTW, such a cover without the text print on it is also fine. thanks, - Henk.

old Sun SCSI chips

by rescue＠hawkmountain.net

I'm trying to nail down the differences between FAS101 and 53C96 SCSI chips used in Sun systems/boards. I believe the 53C96 is 5MB/sec SCSI and the FAS101 if 10MB/sec. (I found specs for Macs with the 53c96 that say 5MB/sec which is where I got that # from). A Sun infodoc article lumps up the FAS101 and MACIO, doesn't indicate the speed of the FAS101, but indicates the MACIO is 10MB/sec. This obviously if correct would make the FAS101 the better SCSI chip if one had a choice between the two (unless there were some other performance drawbacks to the 'faster' chip). I think this is correct, but looking for confirmation. -- Curt

Classilla 9.2

by spectre＠floodgap.com

For the Classic Mac cctalkers not on 68KMLA or the Mac OS 9 list, I booted out Classilla 9.2 for Mac OS 8.6 through 9.2.2, a Mozilla-based web browser for classic Mac systems (thus darn near almost on topic [2002]). This version has a rewritten JavaScript interpreter and a lot of omnibus fixes.

Semi-OT: Apple iPad

by healyzh＠aracnet.com

Okay, I know the iPad is totally OT, but here is my question, does anyone on this list have one, and have you tried using it for reading PDF's off of Bitsavers? How practical is this? I'm finally making real progress at getting my computer "lab" setup with the systems I plan to keep, and don't have a way to read manuals out there. Currently the only computer that doesn't have a VT420 attached is the Commodore 64. Guess I should get the SGI o2 or Sunblade 1000 hooked up... Zane -- | Zane H.

VAX 4xxx DSSI drive sleds, drive covers and DSSI node plugs available, UK.

by binarydinosaurs＠gmail.com

Folks, Found a few of these whilst tidying up our surplus stock room, there's 3 or 4 plug-in drive sleds for RFxx ISEs, quite a few device cover/node plug combos and a couple of TLZxx/RRDxx removeable device covers. We don't want any cash for them but you'd have to pay shipping from Cambridge UK, pick up obviously welcome. Oh, there's a metric buttload of the QBUS slot covers too, though I suspect they'll end up in the recycling.

C64: Chameleon 64

by brianlanning＠gmail.com

I'm waiting for it too. It's ridiculous. Basically, you don't even need the c64 anymore. iirc, you can run a c64 emulator just inside the cartridge. But anyway, it acts like the CMD type accelerators, with three different speeds: normal, CMD supercpu which I think is 20x, and full blast. There's 16megs of memory, SD card slot for 1541 emulation, there's also vga and ps/2 mouse and keyboard connectors. I think it has ethernet also (or accepts that module). It's expensive, but I'm getting one anyway. I'm sure there will be a limited production run and I'm sure it will go for insane amounts of money on ebay later, so it's not lost money. I wish they'd make something like this for the amiga also. brian On Thu, Jun 3, 2010 at 9:59 AM, Zane H.

C64: Chameleon 64

by healyzh＠aracnet.com

I was just looking to see if there was any updated software for my "MMC Replay" cartridge, and I ran across information that the "MMC Replay" has been discontinued (http://www.vesalia.de/e_mmcreplay.htm), and is being replaced by the "Chameleon 64". Does anyone have any info on this? It looks like it will be expensive (about 200 Euro), but I want one! http://www.vesalia.de/e_chameleon.htm Zane -- | Zane H.

Authenticity opinions

by chrise＠pobox.com

I have brought my SWTPC 6800 system back to life that I built as a kid in 1976. It is pretty heavily loaded with RAM cards, floppy controller, etc. and the 8V power supply rail was never really able to hold its own. It sits at about 6.5V now... driving many 5V regulators on the various cards. No where near enough margin going into those. So, I am contemplating the following, 1) rebuild entire power supply using three switchers, 7.5v unit nudged up to 8V and two 12V units to supply +/-12 on the backplane. All of these will fit inside the original cabinet in place of the linear supply's transformer, giant electrolytic cap, bridge rectifier, etc. I'd mount these switchers to an aluminum plate that would fit into the chassis and use existing mounting holes thereby not drilling any new holes in the chassis. This would be the least "period" solution but allow all of the original cards to run in the machine with power to spare. 2) add a new transformer to the existing supply just for the 8V rail. This will also fit but requires moving the existing transformer, cap, DC distribution board-- all efforts that require drilling new holes in the chassis. This would be a more authentic solution since I wouldn't be introducing power supply designs that didn't exist back then. There were actually published mods along these lines in the day but I am little hesitant to butcher the chassis to accomplish this. 3) scuttle the legacy RAM cards, most of which are 4K in size built with 2102's... and one 16K built with 2114... and replace them with a single homebrew RAM card using one 32Kx8 SRAM drawing almost no power in comparison to these old cards. Definitely not period and all the authentic RAM cards would be sitting on the shelf then but the power supply could remain unmodified. Any recommendations on the best choice? Chris -- Chris Elmquist

good news on P112 parts

(beerp) returns t for PLATO@50 tomorrow?

by legalize＠xmission.com

Hey folks, I'll be flying into San Jose tomorrow for the PLATO @ 50 presentation at the Computer History Museum. My flight gets into San Jose around 3:55 PM, but the presentation at CHM doesn't start until 7 PM. I wasn't planning on renting a car, so my mobility will be limited. However, it would be great to meet up with folks for beer and/or dinner before the PLATO presentation. I'll be checking my email until about 10 AM MDT tomorrow (9 AM PDT). -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
