All, I have an Amstrad PPC640D with original box that I would like to pass on to someone. These are reasonably common and not that rare. It makes a great low power terminal (LCD screen) and real serial port, but that is about all I can say in it's favor. It will need to be collected in the next two weeks. If I don't hear anything this it will be going off to the small electricals bin at the local recycling centre this weekend. Thanks.

Cleaning floppy drives

by Hollandia＠ccountry.net

As far as I know, all of the vendors of the "cleaning diskettes" that were available have stopped making them. Does anyone know of a source? Failing that, what is the correct way of cleaning a floppy drive? Thanks, Kurt

DiscFerret update: PCB done!

by classiccmp＠philpem.me.uk

Hi guys, I've just (within the last few minutes) finished the "first cut" board layout for the DiscFerret. It's a 160x100mm Eurocard, with all the "inputs" (power and USB) on the back panel, and all the disc-drive interfacing stuff (power and I/O) on the front. Truth be told, it's not much different to the prototype schematic I posted to the list earlier this year... The 40-pin disc I/O connector carries a standard 17-line ("34-pin") Shugart disc interface with all lines wired, four high-speed 5V TTL "user I/O" lines, +5V (low current) and ground. The state of the DENSITY pin (pin 2) can be driven as an open-collector output, or used as an input (depending on the type of drive you're using). There's an external "power output" connector for the disc drive. This is a dual-row 4-pin AMP Micro Mate-n-Lok (P/N 3-794618-4, mating connector 794617-4 with 794610-1 contacts) which carries +12V, +5V and two grounds. Current-handling capacity is about 1.5A per channel, so plenty for most PC-style drives. There are no cop-outs here -- you can pull 1.5A from the 12V bus, and 1.5A from the 5V bus *at the same time* without any adverse effects. I wanted to use the standard Molex floppy drive power socket, but Molex only seem to make one PCB-mount variant, which is the "input" socket (which has a recessed body, but contains male pins -- go figure)... There are also three status LEDs -- Power, FPGA Status and PIC Status. The first is always on when the +3.3V regulator is running, the latter two are controlled by their respective devices. A plastic light-pipe redirects the light from these LEDs to the front panel. Simples! For the curious... Schematic: http://www.discferret.com/temp/discferret_sch.pdf PCB layout: Checkplot: http://www.discferret.com/temp/discferret_main_chk.pdf Top copper: http://www.discferret.com/temp/discferret_main_top.pdf Bot copper: http://www.discferret.com/temp/discferret_main_bot.pdf Top overlay: http://www.discferret.com/temp/discferret_main_tov.pdf EAGLE project files: http://www.discferret.com/temp/eagle/ (you'll need all the files in this directory) Next step is to do a full design review (i.e. print the board and schematic out REALLY BIG and go over them with a loupe), create a Quartus constraints file and test-synthesize the FPGA microcode. But first... it's 3AM and I'm tired. Sleep time! zzzzzz.... -- Phil. classiccmp at philpem.me.uk http://www.philpem.me.uk/

How to repair Tektronix 4696 inkjet and what to use for the cleaner fluid cartridge?

by rmay635703a＠yahoo.com

The maintenance fluid is sucked in each time you turn the printer on and expelled at some point.? Basically the print heads sit in a bath of it while not doing anything or while at the carriage return position,? the printer draws the maintenance fluid from the cartridge (which is a plastic bag) and expells it into the same container but on the outside of the plastic bag, one instruction warned not to turn the printer on and off too much and I found out the hard way why as a bunch of colorfull maintenance fluid spilled all over the table. My main interest was figuring out how to dissassemble the machine, at one point there was a maintenance manual for the 4695, sadly the archive that had it didn't seem to want to put it up for download.

HP 9845 replacement ROM boards

by hp-fix＠xs4all.nl

The rom's on my HP 9845B are getting unstable when the machine is heating up, they're giving errors. Ansgar Kueckes from <http://www.hp9845.net> www.hp9845.net has a very nice solution, the design for a replacement board using flash memory. It includes the pcb desing, I asked him permission to use his design and produce a certain amount of PCB's and to sell them for cost price to other collectors. He agreed, the more I order the cheaper the price will be, so who wants a PCB for his HP 9845 ? More info on the project at : http://www.hp9845.net/9845/projects/romboard/ If you're interested let me know off-list -Rik

Slightly off-topic, but still interests many of you. Dozens of vintage (mediocre condition) electronic and HAM radio equipment for sale in Costa Mesa, CA. Storage unit needs to be cleaned out! None of it is mine, I'm just assisting. There is a Kaypro II, Kaypro 4, a floppy drive assembly or two. No S-100 systems. The owner is very unlikely to ship anything, but I can if required. See pics at this link: http://popbottlecaps.com/temp/electronics.html I took the Altos 586, with 2 feet of manuals, and some software.

Are there any Tektronix graphics terminals demos out there?

by ethan.dicks＠gmail.com

Hi, All, I'm dusting off a Tektronix 4105 color graphics terminal (for VCFmw) and while I have the docs and such, I lack the time to write any code >from scratch to scribble on the tube. Does anyone know of any demos out there (for any platform, really - I can emulate anything that's likely to come up if I don't have an original system)? I see some mention out there about software for TOPS-20, and I'm sure there was stuff for VMS, and there may be some stuff out there for UNIX (the terminal was made in 1983). I'd also be happy with older Tektronix demos. The terminal is pretty versatile about what it emulates. I know I could find plot libraries and such and write something from scratch, but I have so much else going on that I just won't have time to be writing code as I collect, test (and probably repair) gear to go this weekend. Ideally, there's either some canned files that can be emitted to the terminal, or some FORTRAN or C code that can be compiled and pointed at a terminal. Thanks for any tips. -ethan

imaging multi-session CDs

by spectre＠floodgap.com

What are people using to make images of multi-session CDs? I have a lot of old Mac games I'm trying to image and store that have both audio and data sessions (in fact, this was pretty common). I can certainly rip them separately, but it would be nice to be able to hold them in a single archive, preferably something Toast or Disk Utility can burn.

It's certainly widely known, but with some differences. From the description I read of the incident when I googled stuff about my then-new printer, the person just took a bite off the ink block. The Wikipedia entry on "Solid Ink" also uses the wording "...ate part of a stick...", which IMHO is a bit more credible than the other version.

Commodore PETs, SGI Personal IRIS & More @ RE-PC in Tukwila

by derschjo＠mail.msu.edu

Just a heads up -- dropped by RE-PC in Tukwila today to recycle a few things (nothing classic, I assure you!) and they had a lot of cool old stuff for the first time in awhile; not the best prices but I thought I'd let you guys know, just in case. - They have several PETs -- 2 or 3 8032s and a couple of 2001s (none with chicklet keyboards, alas). Prices were between $100 and $200. They all appeared to be described as "not working" but were in good cosmetic condition. - There's an SGI Personal IRIS 4D/25. Looks to be complete, with tape drive & hard drive. $90, unfortunately... - An Intertec Intertube II terminal, marked as "not working", $35 - A Data I/O 120A gang EEPROM programmer. Kinda neat, a bit big for my tastes, though. $50. - A Franklin ACE 1000, good condition, $16. Probably a few other things that have slipped my mind, but those are the major ones... - Josh

Why CD carriers? was: Wanted: DEC RRD50 CD-ROM Manuals

by chd＠chdickman.com

What was the reason for the carriers used on first generation CD-ROM drives? My first CD-ROM drive cost about $800, but it included an encyclopedia. :-) It used the "standard carrier". I have a Pinnacle RCD-1000 disk burner that also uses the same carrier. I remember that it was attached to an IBM PC-AT or something close and that we basically turned out the lights in the room so as not to disturb it during a burn. The audio drives used the drawer. I know the error correction is better on the audio disk than the data disks, but I haven't found the data disks to be that unreliable. Anyway, why the carriers? -chuck

The link to the picture above didn't work for me, but I found the article in KP Surplus' eBay shop. Putting the maintenance cartridge P/N into a search machine took me to http://hazard.com/msds/f2/blx/blxkp.html, which has the MSDS for the fluid and also states the composition: DIETHYLENE GLYCOL MONOETHYL ETHER, Fraction by Wt: 20%; TETRASODIUM ETHYLENE DIAMINE TETRAACETATE, Fraction by Wt: 0.3%; WATER, Fraction by Wt: 79.7% The term "Maintenance cartridge" was known to me from the manuals of the later Tek/Xerox "Phaser" series solid ink printers, since I have a Phaser 340 standing in the basement since last year. I think the name refers to the fact that it has to be changed as a part of regular maintenance; it has however to be installed all the time for the printer to operate. In these printers, the maintenance cartridge applies a clear oily fluid from a plastic bag to the surface of a heated metal drum by means of a felt pad. This serves as a sort of anti-stick coating for the ink (think "fuser oil") because the image is first printed to the surface of the drum to be transferred onto the paper or film later. There is some sort of MSDS buried in the appendix of the Phaser 340 User's Manual which indicates that the fluid in the maintenance cartridge is silicone oil (Polydimethylsiloxane, CAS Number: 63148-62-9). Mostly harmless: "Hazards: ... Ingestion: Swallowing large amounts could cause discomfort. ... No first aid should be needed." The usage counter on the maintenance cartridge is realised by a spindle driven from the printer mechanism by gears and a moving block which hits a mechanical switch when the cartridge is supposed to be depleted. ISTR there is some sort of anti-windback device but nothing that looks impossible to overcome. The bag even has a thermo-sealed filling line attached to it which could be used to replenish it.

I own an old Casi Computer Portraits System with an old dried up Tektronix 4696 inkjet printer (the one with the actual wells)? Anyway I receieved it sort of working but it only would print Black and blue the other colors were plugged, I made the mistake of turning on and off too many times and wasted all teh fluid in the one remaining maintenance fluid cartridge.? Anyone have any ideas how to coax this beast to life?? I can pretty much use any ink.? Also I need to know the Dipp settings on the unit because i have a feeling it isn't configured for my box. ? The maintenance fluid has me stumped, distilled water maybe? ? Thank You Ryan May

Olivetti JP101 ink cartridges?

by ard＠p850ug1.demon.co.uk

Since we are discussing obscure printer consumables... I have just bought an Olvetti JP101 on E-bay. This is the 'sparkjet' printer that was sold in the mid-1980s. It was commonly used over here with the BBC micro, and I beelive an Acorn-badged version existed. Mine has the Olivetti nameplate. One problem (and I knew this before bidding, I am not complaining) is that the ink cartridges for it are unobtainable. The machine came with a nearly-new one in it, and 2 brand new spares ,so I can at least try it out. But when i've used those up, nothing... The ink cartridge is a glass tube tapered to form a jet at the front end. It contains a solid ink with a compression spring [1] behind it which also acts as an eleectrical conenction to the rear metal end cap. Thetube is fitted in a little plastic holder. It clips into the printer carriage, an high voltage is applied between the ink (via the end cap and spring) and a metal paper guide. The resulting spark transfers some ink to the paper (note that the sparrk does not attempt to pass through the paper, and the paper is not special in any way. It's a pity the cartridges are unobtainalbe, since apart from the HV transformer module (which also contains at least one rectifier diode and maybe a limiting resisotr), the mains transformer (which is not likely to fail) and a programmed 2764 EPROM, all the other electornic compoents are standard (Z80 CPU, Z80 CTC, TTL chips, etc) and easy to get. The mechanism is pretty well made too, and looks easy to keep going. Does anyone have any suggestions as to how to make ink cartridges for this machine? -tony

Free: HP 264X terminal boards...

by derschjo＠mail.msu.edu

Hi all -- Doing some cleaning, I came across a box containing a number of old HP boards. I've had these a long time -- I think someone gave them to me when I was still in high school. Based on a cursory search of the 'net, these look like they possibly belong to an HP terminal, of the 264X family. (see pics: here http://www.hpmuseum.net/exhibit.php?hwimg=240) I don't own an HP 264X terminal, so I obviously have no need of these -- maybe you do? They're in decent, but not great shape. Obviously I've no idea if they work. If anyone wants them, you can have 'em for the cost of shipping. Drop me a line. The boards I have are labeled in the upper-left corner thusly: 02640-60192 CONTROL MEMORY (these have what appear to be ROM chips) 02640-69192 CONTROL MEMORY 02640-60209 PROCESSOR - contains an AMD fabbed 8080 processor w/hp PN 1820-1701... 02640-69124 DMA 02640-69112 DSPLY CNTL 02640-60125 GRAPHICS M-CONTROLLER 02640-69126 GRAPHICS DISPLAY PCA 02640-60171 UNIVERSAL MEMORY PCA - Josh

I'd always thought that the 3100/20 used that 26-pin interface, but maybe there's more than one version; I've got a 3100/40 which uses a normal IDE interface. On the other hand, I have a 3200 which does use the 26-pin version while someone on another forum says that his has a normal ST-506 ST-125. And now you come along with a 44-pin connector... Is there a separate power connector? I had heard that the 3100/20 had a non-standard implementation of the ST-506 (MFM) interface; perhaps that's the 44-pin version, and the 26-pin version is an early IDE interface. They are neat computers, but assuming it's still working I'd get that data off ASAP, using the serial port or diskettes... Anybody else out there that can shed some light? mike

This might take me some time, but I am keen to do it as there is very little technical stuff about the MW4 on line. I might try and disassemble the code too (but I don't think IDA has a 1802 option!)

8088 CPU tester module

by binarydinosaurs＠gmail.com

Folks, In digging out some old Apple stuff last night I came across a module for a CPU testing machine I had years ago. It was a black IBM compatible PC called either an AMS3000, MSA3000 or MST3000 (I can't help but think of MST3K on that one though :)) with an EISA interface that allowed a connection to one of many CPU module testers, at the time I had an 8008, 68000, z80 etc - host adapters that you connected over an in-place CPU module. This module is for an 8088, is in its box and is heavy. Does anyone remember it or even want it before I recycle?

DEC/Compaq XP1000 can't see keyboard - ideas?

by classiccmp＠crash.com

I've recently received a Digital/Compaq XP1000 - 667MHz 21264 Alpha CPU, a mid-tower system nigh-identical to the Professional Workstation series (PWS 433/500/600). It came with 1G RAM and a PowerStorm 4D/20 PCI video card. I can access the SRM console through one of the serial ports, SRM version is V5.9-1. Unfortunately the machine refuses to recognize any keyboard I've tried. I've used the DEC LK411 off a working VT510, a spare LK411, an SGI PS/2 keyboard, and an IBM PS/2 Trackpoint keyboard. In all cases I get a message during POST that reads "No keyboard plugged in" before the "E8 ... E4" countdown. I've double-checked that I didn't have the mouse/keyboard ports backwards at various points. :) Just now I powered it up with the Trackpoint and I see all three status LEDs on the keyboard flash, then nothing. I get the "no keyboard" message and SRM prompt on the serial port. No output from the PowerStorm, and if I hit the CapsLock on the keyboard the LED does not light. A SHOW DEV on the console gives an appropriate-looking entry for a "vga0" device. A SHOW CONFIG gives a lot more output, including a "PowerStorm" device in slot 9 of hose 1, bus 2. However I have never gotten any output on the video card. I have not yet tried it in a PC. Any suggestions for what to try next? I'd like to have the option of running DECwindows... Thanks, /--/Steve.

How to repair Tektronix 4696 inkjet and what to use for the cleaner fluid cartridge?

by rmay635703a＠yahoo.com

Nope I don't have any of the fluid left, but it appears I "may" be able to order a cartridge online though its $51 refurbished and I have the feeling although listed likely would be canceled should I try and order one. ? Also $51 seems quite high, I think new they were in the $10-$20 area. ? Ah well? I will have to figure out how to dissassemble the thing to clean the heads and wells, I was told window cleaner does wonders. ? Cheers Ryan

Wanted any Wax thermal Supplies for Casi Futura 100 portrait booth

by rmay635703a＠yahoo.com

Not sure if this is OT or not but my folks still use a 23 year old Color Computer Portrait system at fairs and we need ink and wax thermal Paper for our Shinko CHC 545 or Shinko CHC 445?we also have an old Panasonic Omniflex EPL-RAT unit and a Tektronix 4696 which I consider RIP.? If anyone here knows of anyone with old supplies laying around or where I might ask it would be appreciated.? I need both photo paper and T-shirt paper. (tektronix wax thermal supplies also seem to work, if they are for the ROLL wax thermal not stick)? Oddly enough our system was supported by Casi then QLT up until April 2000 (a long time I know) they released an HP 2000c printer driver for the unit and gave up.? Sadly the driver is crap, slow, inaccurate color,?unreliable and very low resolution compared to the Shinko 545 driver.? I often wondered if anyone could reprogram the 2000c driver with the Shinko dot pattern for better accuracy and speed?? The system is a Motorolla 68010 with 2mb system memory and 1mb video memory and Uses Innovion IDOS as the OS.? I can read and image the 720k floppies but don't have proper resources to know how to edit them effectively.? I had a little programming in high school and college but I would need a systematic method to approach this unit, I would love to be able to program it myself but never got to the point I could. ? Also the system saves photos to a floppy disk in 16bit targa format (not a dos disk though)? I can using a imaging program take the photo off, but sadly the pallette is completely wrong, I can tell who the people are but they are in psuido colors.? I often thought that might be a way for my folks to continue using their simple system then simply print the photo on a normal PC. ? http://arstechnica.com/civis/viewtopic.php?f=20&t=130698 ? Anyone want a free unit to play with to write a driver? I am located in central Wisconsin. Thanx Ryan May

source for large capacity electrolytics

by bear＠typewritten.org

Folks; The 5V rail in my Sun 2/120's PSU recently failed suddenly while the system was running. No pop, but the rail measures out around 2.5VDC. I believe I have tracked the fault down to one of a pair of 26000uF electrolytics which are in parallel across the 5V output studs. These are screw-lead, rated for 7.5V (12V surge), 85 deg. C, -10 +75% tol. They are 1.375" dia, and 2.125" tall. Mechanically, there is no room for anything even slighlty larger. Mouser stocks a part which is physically too tall---at 3.125", too tall by an inch. This is a 10V (12V surge) part. They also stock a 50V part from a different manufacturer which is even taller (>4"). There are 10V (12V surge) parts that fit, but have too low a capacitance (18000uF). There are 7.5V (9V surge) parts which will fit, but have too high a capacitance (49000uF), and I'm not totally sure how to be certain that a 9V surge rating is adequate in this application. Digi-key stocks nothing even close. Any suggestions? ok bear

For sale: Some DEC stuff

by hachti＠hachti.de

Hi folks, anybody interested in buying the following? - Omnibus core memories (tested good) - M8350 TTY interfaces (tested good) - RK05 disks for pdp11 (12 sectors) (used, new, tested, untested) - RK05/RK05J/RK05F disk drive (untested, tested good, broken) - RK05x spares - TU56 DECTape (tested working, untested, broken) - TU56H single DECTape - PC05 paper tape reader/punch - Some other Omnibus cards PDP8/M ******* A PDP8/M computer. Very nice (near perfect!) condition front panel. Chassis condition lower medium condition. Backplane and PSU (220V) ok. No top cover. System configuration to be discussed. First guess would be 12K core, TTY, CPU - all tested stuff. PDP8/L ****** PDP8/L minicomputer, untested, keys bleached out by sun. Untested (really untested, currently don't have the time to repair the machine) but complete with the 4K core stack. 110V Keys kan be used from a pdp8/e - they're the same. But not from pdp8/m. Those have the wrong colour. The PC05 is a strange machine: The reader portion of it was used on a pdp8/e (PC8E interface). Normally you use PC04 for pdp8 computers. The reader part seems to be compatible. The punch part is untested. Mechanics look fine. I guess that there are also missing boards on the punch side. Nice condition though. No cover, 110V. Location: Northern Germany (Hannover, Kiel). Open for reasonable offers. Can send packages up to 30kg. TU56 can be shipped in two packages. pdp8/m fits a package. 8/L cannot be shipped internationally. Kind regards, Philipp -- http://www.hachti.de

RCA CDP 18S604B

by marvin＠west.net

I just found a couple of standard bus cards marked "CDP 18S 604B" and no real idea what they are. A Google search gave 3 results, all in German >from their edition of Computer Weekly dated 1981. One looks to be in the original packaging, and the other looks used with an expansion PROM board. Unfortunately, no docs although I'll be trying to see if the person who had them has any docs left. Anyone have any idea what these things are?

The RRD40 that I have was given to me so that I could learn the way of the VAX and VMS. I have since found other CD drives that understand the special way of reading the short CD sectors. Today I am reminded of it, I am bound by honor to pass this drive on to another VAX/VMS kinder. I will send this drive to someone that wants to learn VAX/VMS and needs it to boot the OS. -chuck

It maybe that DEC put a SCSI-1 bridge controller inside the RRD50 box so it presented that interface to the world. If possible a scan of the manual would be greatly appreciated. U can contact me off line to figure out how to do it. Tom t<dot>gardner<at>computer<dot>org
