And let's not forget "what's the hardest part about emulating Gerald Ford
on a PDP-8? Figuring out what to do with the other 3K."
Hi all,
I'm looking for various Itanium systems:
IBM eServer xSeries 380
IBM IntelliStation Z Pro Type 6894
Fujitsu Celsius 880
Silicon Graphics 750
HP i2000
HP Integrity rx4610
Dell Precision Workstation 730
Dell PowerEdge 7150
If you have a system you want off your hands, I'll pay!
Thanks,
Vivianne

It (the Osborne Powr-Pac (tm) ) has a what the manual says is a DC-DC inverter that plugged into a Gould lead-acid battery (or the cigarette-lighter socket in a car) at one end and the AC input of the Osborne 1 at the other. I have read on this list that Lee denies that OCC ever sold them, but I have one that I bought for $50 at Compumat in Chicago on October 10, 1983 -- I still have the unit, receipt, and User Registration card. It came with a glossy-printed grey-and-blue manual, like other contemporary OCC products.
If anyone wants a copy, I can email you a PDF scan of the user manual.

For various reasons (including, but not limited to, insanity and obsessiveness*) I am building a diode laser based tape punch. It's not specifically for a classic comp, but I'd like to stick with standard format so that it'd be useful for making custom tapes for members in the future. I will probably need to make dozens of tapes so using actual, vintage rolls is out of the question. Does anyone know if 1" tape is used for anything else and where I might find some new? Otherwise I may have to add paper-slitter to my project list and make my own.

Hello!
I have an IBM 6152 aka IBM RT system I rescued. (It may be a 6151?)
I'm 90% sure it has colour graphics. The system does seem to POST
correctly (according to the LED on the front) but the CRT is dead. I'm
wondering if anyone has built an adapter to hook this to a VGA
monitor.
I'm a bit confused by the pinout. It has high and low bits for the RGB
(and associated grounds for each colour.) So I'm not sure how that
would work hooking to a more modern monitor.

Otherwise I need a crash course in fixing CRTs.

Hi:
Doing some research for historical purposed – no litigation at all – trying to identify the first “legal” PC-DOS compatible PC, “legal” in the sense that it’s BIOS was not a copy of an IBM BIOS. Eagle gets the honor of being first MS-DOS compatible and getting sued for copying IBM’s BIOS 😊
The Compaq Portable which shipped in November 1982 is generally credited with the first legal MS-DOS compatible PC. AFAIK it could not run PC-DOS and those applications which depended upon certain IBM BIOS commands would fail.
The first “legal” BIOS is generally considered to be from Phoenix which was announced in May 1984 and so far I have been unable to determine its first system deployments. FWIW Wikipedia points to HP, Tandy and AT&T as some time adopters of a Phoenix BIOS but my research so far is that Tandy’s T1000 family announced in October and November of 1984 was the first system to be PC-DOS compatible and it did not use a Phoenix BIOS! Such PC-DOS compatible HP and AT&T systems were much later and the Tandy BIOS was written by programmers of Tandon Corporation, the OEM supplier of the first Tandy T1000s.
Can anyone identify a PC-DOS compatible PC announced earlier than October 1984? Citations would be greatly appreciated.
Thanks
Tom

A small booklet included with the many documents I received indicates as of 1982 the Pixel 100/AP ran a System III derivative. The booklet goes on to present a summary of user commands and options. Despite the System III basis, included among these are the C shell and ex/vi.

This was originally posted to “The Unix Historical Society” email list and I asked the original author for permission to forward it here.
If anyone is interested in such equipment.

There are two ways to write error-free programs; only the third works.

I have an Otrona Attache 8:16 with the DC option, so it was sold. (I used both the Osborne and the Otrona in Peru, so having a battery option was an advantage.) However, my Attache has the disk drives that both spin up at the same time, and the DC option does not supply enough power to properly spin both drives, so the computer will reboot if you try to read or write anything to disk while on DC!
I’m traveling now, but will open up my Attache and take some pictures for you in a couple of weeks.
