My company had a cash flow problem and had to close the office. We thought we might come out of it and saved our system in my garage. We did not turn around and so I have a VAX with DecServers and a printer to divest. I also included the VMS documents. Primarily I would be happy to work with someone to relieve me of the hardware.

know where I can get a 800k drive for a mac SE?

I was thinking of "autoinject" and not 800K vs. 1.44MB. However, unless you're a purist for collector's reasons, I think the 1.44 MB drive will work fine in the SE. It will read and write 800K and 400K disks just as well as an 800K disk drive. The only issue I can remember is that you might need a different floppy drive cable (red stripe vs. yellow stripe) or was that an auto-inject vs manual-inject cable issue? It's been so long since I've dealt with floppy replacement that that old knowledge isn't terribly accessible any more. But I do know that the 1.44 MB auto-inject drive is a good functional replacement for the 800KB auto-inject drive and the only reason not to do it is if you're trying to keep the machine pristinely original.

Apple I BASIC dump

It isn't that hard. > Did that to move Infocom game sectors from an Apple II to a C-64. > It was a bit rough, but with both CPUs bit-banging away at 1200 > baud, it took a while. In the end, though, the operation was a success. Likewise, once did a similar thing to transfer a particularly interesting textual adventure game from an Apple II to an Atari 800. Cobbled together a three-wire cable between game ports on each machine and used a very simplistic transfer method: Used one conductor as a single-bit DATA line, another for RCVR-READY, the last for signal ground. We sent just one bit at a time, with the RCVR-READY basically ACKing each bit. Certainly wasn't an efficient way to send data, but there was no reason to finesse it any more, since it was a one-time setup. If I remember right, we figured that our 42KB transfer would take about 75 minutes. After a slightly extended lunch, the transfer was complete. I guess that works out to about 10 bytes per second! With a few more minutes to patch the 'TTY-IN' and 'TTY-OUT' entry points, we had a fully working app. If I remember correctly, we even figured out how to modify the game save functionality for the Atari, too. - Jared

I am the author of a 1999 term paper for the University of Regina in Canada called the "Downfall and Contributions of the Xerox Star" which featured a now oft referenced and updated bushy tree diagram. I recently started a Wikia about the HCI using the said diagram as a reference. My mission for the Wikia is to create a collaborative online encyclopeadia about the evolution of the human computer interface, the people and developers involved, and the terms that are used. It's about two weeks old and a lot of what's on there is mostly stubs. Naturally, it's a lot for one person to tackle alone. I'm looking for collaborators, authors and editors to help hammer it into shape. I'm wondering if you yourself would be willing to have a peek, or if you can help point me in the right direction.

TRS-Xenix 1.0 Development System disks?

by derschjo＠msu.edu

Anyone have the development system disks for TRS-Xenix 1.0? I just recently got my Model 16 running Xenix 1.03 and having a compiler (or any other software, for that matter) would be nice. I've found images for Xenix 3.0's development system, but my M16 lacks the proper modifications to run 3.0. Thanks, Josh

Apple 1 BASIC dump

by vbriel＠yahoo.com

Well, this is nice work but it was done 5 years ago, has been disassembled and currently is in the replica 1 kits EPROM. Achim Breidenbach wrote a program on his Amiga to read a .wav file of an original copy of BASIC and disassemble it. I would say, Achim deserves credit for being the first to read the tape and make a listing available. By the way, replica 1 users found an error in this "confirmed" version of BASIC. Using my Apple IIplus I was able to read Star Trek and Lunar Lander from .wav files of original tapes. Vince Briel Computers home of the replica 1 and Micro-KIM http://www.brielcomputers.com

If your order is trouble free, then Shreve is reliable. If there are problems with your order (e.g. defective/missing items), they have a reputation for not being particularly helpful. Jeff Walther

Osborne Computer 4 (Vixen) prototype?

by bob＠jfcl.com

I've found machine that I think is a prototype for the Osborne Vixen. >From the outside the case looks exactly like a Vixen case except that mine is a ugly brown color rather than the grey/white color scheme you usually see and when you open it up it's slightly different from a "production" Vixen - the floppy drives in mine are horizontal rather than vertical and the back panel is re-arranged a little. There are no labels of any kind on the machine except for the giant "OSBORNE" that's molded into the plastic, and the PCB inside says "Osborne Computer Corp, Rev 2". When you turn it on, though, it identifies itself as an "OCC 4" and asks for a boot diskette, so I'm thinking that must be what it is. Has anybody seen a Vixen in this style? None of the photos I've found on the web look like this configuration. And does anybody have software for the OCC4? Will the boot diskettes for an OCC1 or Executive work on it? Thanks, Bob Armstrong

Osborne Computer 4 (Vixen) prototype?

by sellam＠vintagetech.com

Doug Salot (used to be a regular here a long while back) was the first person that I know to find one out in the wild. Judging by the number of people who claim to have one (3-4 it would seem as of now) there are probably a handful that were made for prototypes, and then they decided to rotate the drives for the production models (perhaps to accomodate the larger display?) I have a "normal" Vixen, which are difficult to find themselves. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

No, it's a very dark chocolate (I guess most people would just say "black"). Judging from the photos I've seen, I'd guess that my whole case is about the color of the end panels on a "production" Vixen. And it's not structural foam or acrylic or painted as far as I can tell.

VAX Cobol

by iamvirtual＠gmail.com

I am trying to locate a copy of Cobol suitable for OpenVMS 7.3 for my hobbyist VAX 4100 machine. Does anyone know where I could stumble upon a copy? I have also searched for the VAX OpenVMS Software Layered Products Library (AKA the 'motherload'), but have not located a source. I am really interested in a copy of this CD. Thanks! --barrym

IBM 360 Mod 70 picture desired.

by caveguy＠sbcglobal.net

Hi all, I am looking for information and most importantly a picture of the IBM 360 mod 70. What I know about it is : It was introduced in 1964 along with the "30, 40, 50, and 60's. There were mockups and photos of the 360 family made, 8x10's were sent out to key sales people and press as part of a product launch kit of some sort, most with an assortment of disclaimers on the back. As I understand it, the 360 Mod 70 was never shipped. But what happened to it? It has been said that it evolved into the Mod 75 before it hit the streets. Was it shipped to an undisclosed location, under a new GSA number? Or was it scrapped early in life, and gave up its core to something else? if so what? My first question is what did it, or was it suspose to look like. What I am real interested in is any picture showing the console. Bob Bradlee

WTB TU-58 drives and tapes

by jhfinedp3k＠compsys.to

I have been asked to find some TU-58 drives and tapes. The drive would need to be the external dual TU-58 with an RS-232 header interface (of 10 pins). Does anyone have any to spare? Does anyone have any price estimates as to how much they cost these days? Please contact me off list if you have any that are actually available. Sincerely yours, Jerome Fine

I finally finished my Obtronix Apple 1 reproduction!

by us21090＠yahoo.com

All, I finally finished my Obtronix Apple 1 reproduction! Actually, building the Apple 1 didn't take much time at all! It was the custom work on the mounting board, the curved and angled plastic leg brackets, and, and ... I uploaded photos of it to http://www.vintage-computer.com/vcforum/album.php?u=6611 I also have a request: My Obtronix Apple 1 reproduction had a bad Signetics 2504v. I don't think it was DOA (I believe it just "developed" the problem recently). The Signetics 2504v is a 1024-bit dynamic shift register, 8-pin dip. It's used here to as part of the display control. The problem I saw was odd numbers (1,3,5,7,9,A,C,E) in every other screen column were displayed as the preceding ASCII character (0,2,4,6,8,@,B,D). Data from the keyboard was stored correctly in main RAM. The video memory problem just displayed it incorrectly. Anyway, does anyone have a source of a Signetics 2504v? Or possibly, is there other more readably available junk-hardware-for-parts that I could pull a 2504v? Thanks! Scott Austin

Can anybody tell me a rough estimate of what a Northstar Advantage would be worth? I believe it has one floppy and a HD in it (definitely not dual floppies).

free BA11 shell, RA81 shell, 9-track tape cleaner; Boston area

by brad＠heeltoe.com

I'm moving out of my old rented garage (into a new garage :-) and I have two things to give away (for pickup) in the Boston area. - BA11 cabinet which is solid but missing various power supplies. It was ` once an expansion cab for an 11/730. I think it is 1/2 full of backplane. - RA81 which is missing an HDA. I think it has everything else. - nice 1/2" 9-track tape cleaner device; good for retentioning also (I ended up with two of these and don't need two) If anyone would like these let me know. Local pick up only. -brad
