I've seen those cards but I can't remember what they are. <snip> OK I finally got the grey matter working and I remember what those cards are. They're DOS coprocessor cards. Yes, your HP can run MS-DOS. Somewhere I have some of the cards but I never found software for them. If you got a drive with your system, look at it carefully and see if it has the necessary SW. If you find the SW, I'd love to get a copy. Joe

Commodore Adding Machine plus FREE stuff to get rid of

by fernande＠internet1.net

Okay here's the deal. I bought this Commodore 202 adding machine from Goodwill a few years ago, I think for $2.00. I promised it to someone for 7.00 plus shipping, but I never got around to making it happen. I can't recall who I promised it to, Though. If I promised to you, please let me know if you still want it, or not. I want to get it out of my way .... I box it up and ship it this time! It does have a piece broken out of the case by the plug. I don't know if it works as I've never tried plugging it in. Free: 2 72-pin 4 meg simms, marked "ASSY IN USA POWMEM" 1 IBM 7024-113 wide scsi case, that I think is only good for 3.5" single ended drives. The board that has the external connectors on it says "Single Ended EPOW". It's dis-assembled. The inside bottom part of the chassis has some corrosion on it.... not rust, it's whitish and is from when I tried soaking off some sticky stuff off of it, it should clean up. I never did get all the sticky stuff off. The rest of it is very nice. I'd use it myself, but I need a case for 5.25" FH drives, not a 3.5" drive. Please respond privately.

New book

by stanb＠dial.pipex.com

Hi, I've just received my copy of a new BBC/Granta book "Electronic Brains, Stories from the dawn of the Computer Age", author Mike Hally. ISBN 1 86207 663 4 I've not read it yet, but from a quick flip through it looks like an interesting, non-technical, account of the early years of computers in the USA, UK, Russia and Australia. Just thought you might be interested... Interest in classic/old computers seems to be entering the mainstream these days. -- Cheers, Stan Barr stanb at dial.pipex.com The future was never like this!

Obscure DOS question

by vcf＠siconic.com

MS-DOS 3.3 has a limit of 512 entries in the root directory. I have a need to put more than this. Was there ever a way to put more than 512 files in the root directory? Some sort of patch or utility? Did previous or subsequent versions of MS-DOS allow more entries in the root? Another question: When using the SUBST command in MS-DOS, you cannot aparently substitute the C: drive. I seem to recall that MS-DOS 6.0 allowed this, although I might be confusing that with the ability of LANtastic to redirect the C: drive to a network drive. At any rate, what I'm trying to do is overcome the limit of 512 file entries in an MS-DOS 3.3 root directory. Does anyone know how to accomplish this?

Totally OT, but frustrated.....

[OT]: CDC machines featured in "Die Hard"?

by philpem＠dsl.pipex.com

Hi folks, Really pushing the boundaries of on-topicness here, but I've just been watching Die Hard (fairly good film as far as "omigod! he's got a gun! blast him!" type films go) and spotted what appeared to be a CDC rack in the background of the "computer room" scenes (well it certainly had "CONTROL DATA" printed vertically up one side). Coloured grey with blue doors and text. Anyone know what they are/were, just for curiosity's sake? I'd check google, but for some reason my router is refusing to forward HTTP (damn NAT keeps falling over). Later, -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem at philpem.me.uk | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.me.uk/ | 48xCD, ARCINv6c IDE, SCSI ...

origins of "kludge"

by tomj＠wps.com

I know this could be the start of YET ANOTHER thread "Oh I think it's older than that..." but to avoid that, let's raise the standard from opinion/hearsay to printed word. Man I wish I had a collection of pre-1980 DATAMATIONs! From _ENCYCLOPEDIA OF COMPUTER SCIENCE_(Van Nostrand), 1976: KLUDGE The word "kludge" is a term coined by Jackson Granholm in an article "How to design a kludge" in _DATAMATION_ (February 1962). The definition is given as "an ill-sorted collection of poorly matched parts, forming a distressing whole". The design of every computer contains some anomalies that prove to be annoying to the users and wghich the designer wishes he had done differently. If there are enough of these, the machine is called a "kludge". By extention, the term has come to be applied to programs, documentation, and even computer centers, so that the definition is not "an ill-conceiverd and hence unreliable system that has accumulated through patchwork, expediancy, and poor planning". The first kludge article triggered five others ("How to maintain a kludge", etc) in subsequent issues of _DATAMATION_. Four of the articles may be found in the book _FAITH, HOPE AND PARITY_ edited by Josh Moshman, Thompson Book Company, 1966. -- F. Gruenberger [Said book found at abebooks...]

hp2114 basic

by Tim＠rikers.org

From what I hear, the system I used was not one of the TSB series. I'm still interested in trying it out. I don't see binaries online anywhere. Can someone point me to them? I never did any admin on the systems as a student. I only had access using BASIC. I have booted up SIMH with the hp basic stand alone, and it's similar but lacks some features our system had like string variables. http://oscar.taurus.com/~jeff/2100/hpbasic/basic1.abs I see on jeffs site the source tapes for 22255 "Four user BASIC". Perhaps this is the system we were running? 2 CRTs, one ASR-33 and a card reader would mean 4 users, correct? http://oscar.taurus.com/~jeff/2100/hpbasic/index.html Anyone willing to give be instructions on how to get the files assembled? I would think I'd load something like the "extended assember" via PTR: http://oscar.taurus.com/~jeff/2100/siotapes/extasmb.abs jump someplace? and then feed in each of the basic tapes on the same PTR? My experience has been with Linux on all kinds of hardware, from x86 servers and desktops to alpha, sparc, ia64, mips, ppc, sh3, and many arm systems. Most recent work is with ARM boxes. I was deeply involved with the SHarp Zaurus release while working at Lineo (or Embedix, or Metroworks, or whatever they call themselves now). I have simh up and running. Not the same without the blinking lights. Perhaps Jay's emulator will have blinking lights? We did a version of VNC for the Zaurus that had a "skin" which was a scanned image of the device. I envision the same interface on an emulator. click the buttons with the mouse, turn the key to lock/unlock, Would be nice to have a tape reader with audio and perhaps a mag tape too. ;-) There used to be some internet accessable simh access systems running. Are they still? I notice that simh just loops like the actual machine would. This means it eats up 100% cpu all the time. Seems to me that should get hacked somehow to detect "idle" states, and select() someplace for a short ammount of time instead of looping all the time. If I ran the simulator on my Zaurus it would suck the battery dry in no time. We can't have that can we? ;-) Well, thanx in advance for the help. I look forward to trying out the 4 user basic environment and see if it's what I recall. -- Tim Riker - http://rikers.org/ - TimR at Debian.org Embedded Linux Technologist BZFlag maintainer - http://BZFlag.org/ - for fun!
