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

Hi, Are you still there in 2010? :-) I need to read data from my friend's old Toshiba PC with HDD 26 pin connector. I would need to know what are the signals, or what is the adapter. Could you provide some schematics? thanx martin stransky | UPS engineer | Nove Mesto nad Vahom Emerson Network Power | Piestanska 1202/44 | 91528 NOve mesto nad Vahom T +421 32 7700 423 www.EmersonNetworkPower.com <http://www.emersonnetworkpower.com/>

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?

RRD40 was :Re: Why CD carriers? was: Wanted: DEC RRD50 CD-ROM Manuals

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

by mdavidson1963＠gmail.com

I'm so excited... I won a copy of the August 1981 issue of Byte (the infamous Smalltalk issue) on Ebay for $4. It arrived while I was away this weekend, so that was an awesome way to end my Labor Day weekend. Mark

Wanted: DEC RRD50 CD-ROM Manuals

by thomas.gardner＠sbcglobal.net

Anyone have a copy of or know the location of the DEC RRD50 maintenance manual, specification, etc.? I'm interested in the interface for historical curiosity only. I'm pretty sure the DEC drive was an OEM Philips CM100. Tom

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
