Anyone here have the speech module for an IBM PC Convertible they want to get rid of? I just got one of these laptops & was hoping to score one. David M.

Anyone off to VCF-UK

Frankly, although I'm sure that most people on here are nice folks, there's only a handful with whom I think I'd have much in common and would spend time and money to hang out with and listen to if there weren't something else that interested me (especially since I don't drink beer or eat pizza). Having read some of these comments and especially the sentiment that unless you're a "celebrity" who cares what you have to contribute, I'm thinking the same as Tony, namely why am I wasting my time here? I've got friends who share my interests and there aren't any ignorant jerks like Evan among them nor do they tell me to fuck off; maybe it really is time to rent a dumpster and just toss in those Cromemcos, Vector Graphics, PETs, AIM65s and the 25-odd boxes of manuals and documentation that are taking up space just in case someone might want or need something one day; with a couple of exceptions they certainly aren't any use to me. Something to think about for sure; I may end up actually thanking Evan one day for finally showing me the light.

GNT 3601 tape punch docs?

by chrise＠pobox.com

Probably a stretch but wondering if anyone has any info (manual, pinouts, service documentation) for a GNT model 3601 8-bit (1") paper tape punch. It was probably better known in the CNC / automated machining world than in computing but my hope is to resurrect it as a backup punch for copying tapes I use with my ASR-33 and thereby save wear on the -33's punch. The unit has serial and parallel interfaces on DB25 connectors but I do not have any pinout information for those. The serial one I can probably figure out. Unfortunately, the unit is a little more sick than "works OK" seemed to imply from the eBay seller. It has what I believe to be a power supply problem because as soon as you try to punch all eight holes with the front panel test button, the power LED dims and the punch jams, apparently from lack of umph to complete the mission. It could also be jamming to start with and that causes the power drop I suppose. In any case, looking for any docs before I open it up and start digging around. I have written to GNT without a reply so far. Chris -- Chris Elmquist mailto:chrise at pobox.com

Apple Lisa 1 for sale

by sellam＠vintagetech.com

I have an Apple Lisa 1 for sale. Yes, it has the Twiggy drives. It includes the Twiggy systems OS disks (2), original Lisa 1 manual, keyboard, original Lisa (rectangular button) mouse. It works. Excellent condition. Normally I would not so brazenly hawk something but I need to raise funds for an imminent move of the VCF archives. I'm entertaining any and all offers. At a minimum, there should be three zeroes before the decimal point. Please contact me directly if you're interested. Photos and more detail will be forwarded upon request. Will ship galaxy-wide.

M51976FP pinout?

by ard＠p850ug1.demon.co.uk

I am looking for a pinout or datasheet for a chip labelled M51976FP. It appears to be made by Mitsubishi, it's a SMPSU controller in a 20 pin SOIC package. I have the data on the M51977, which is similar (I think), but some pins are clearly different. Looking on datasheetarchiver and digchip didn't find anything. And a google search (as ever) found plenty of people who sould sell me 100000 of them, but nothing else). [It's uised in a PSU modile in an HP tape drive that I am working on, so it does have som relevance to classic computers0. Thanks in advance for any help -tony

Looking for Tektronix 4051 programs...

by clay＠ArcherServices.com

I have been fortunate in acquiring and restoring a Tek 4051 recently. I had used one of these back in '77 to '82 and I still have some documentation, and I found other manuals on bitsavers.org but have not located any software. Do you know of any source on-line? I found references on this site (Feb. 2009) from other users talking about building an archive of software for the 4051. I have keyed in a few short programs to test the vector graphics, but it would be nice to have the original standard pack tape programs. Even printouts would be helpful. I recall when I last used a 4051 back in the early '80's we had the ability to dump & load programs using the serial port, and the ability to un-secret the programs. If I can find this information again I would be glad to provide it to help build a software library for this fantastic system. Thanks, C. Archer

Commodore Floppies

by healyzh＠aracnet.com

Can a C1541 or C1571 attached to a C64 read floppies from other Commodore computers such as the VIC-20 or C16? Since the floppy drive is basically a computer attached to the C64 by a serial cable, I tend to think it can, but I don't believe I've ever seen anything on this, and I know I've never tried. I've never had a floppy drive attached to any of my VIC-20's, back when it was my only computer, I only had a cassette drive. Zane -- | Zane H.

MDS Series 21

by cc＠informatik.uni-stuttgart.de

Hi, what exactly is a Mohawk Data Sciences (MDS) Series 21? There's almost nothing on the net about that system apart from one small article in the July 1978 issue of Computer. Is it worth saving? Christian
