I always wondered about this because I could swear that I saw at least one XT Model M in the day... Does anyone know if you can identify a switchable Model M from the keyboard cable being terminated into a modular type jack on the keyboard side? Or was going from the modular jack to a hard-wired PS/2 cord just a cost reduction at some point in time after the keyboard was introduced? Best, Sean I have a model M with the XT style connector. However, it's for either an AT or XT/286 (I have the later). The cable is all that is different (same modular jack on the keyboard side) I haven't tried it on a PC, but from what I know it shouldn't work. Earl

best dos machine

by rmx44＠aim.com

i have been thinking of running a good dos machine or finding one. i find that each machine is different from the hardware to the way it runs the software. some have the use of a hard drive and some don't i have thought of wanting a sorta high end dos machine one that has the use of a hard drive and can run any program that dos can run and not have issues. i remember with dos some programs would run to fast on some machines but with others they would run just fine or to slow. around in seattle its hard for me to find a good dos machine since most of the older machines that became unwanted got sent to a computer ecycler where it got stripped down and killed off for free or that the store sells the stuff for more then what its worth as a whole. maybe one of you might have something or know some stuff.

Copy of DEC Standard 057 (VAXBI Standard)

by krfkeith＠gmail.com

Does anyone have a copy of this? It doesn't appear to be on bitsavers, or anywhere else for that matter. Information in general on VAXBI seems to be difficult to come by, so any is welcomed.

Hello all, As moderator of cctech, and also looking after cctalk, the amount of spam I'm dealing with is becoming extreme. There are about four times as many spam mails which I need to reject as there are proper postings. So could I ask that you choose subject lines sensibly, or you may find they never get through to the list. Subjects like "Look at this" or "For sale" aren't a good idea. That's all, keep up the good work! -- Lawrence Wilkinson lawrence at ljw.me.uk The IBM 360/30 page http://www.ljw.me.uk/ibm360

FS: Corel Netwinder 275 free to good home

by hugh＠blemings.org

Hi, I have two Netwinder 275s with Power Supplies. One lacks the daughtercard that provided the serial port and second ethernet adaptor. I think I have one of the original keyboards as well. First in best dressed for one or both, free for the cost of postage/shipping from Canberra, Australia. Both were working last time I fired them up. Cheers, Hugh

MUMPS compiler/interpreter preservation

by chocolatejollis38＠gmail.com

I don't know how many of you fine people are familiar with the MUMPS programming language, but MUMPS development accounts for about 50% of my income. Considering that it has as storied of a background as UNIX (having been first implemented in ~1966), and is old, I'm wondering if any of you have any thoughts about it. Also, I'm wondering if any private collections have any older MUMPS implementations around, not necessarily so that I can try to get them, but so that I can find out if they've been preserved. Since InterSystems bought out Digital Standard MUMPS, as well as contemporaries from Micronetics and DataTree, these old implementations seem rare and hard to find. I've long wanted to get ahold of a VAX-based MUMPS implementation, but the closest thing I've ever found is an installed copy of DSM for Alpha on a cluster I picked up, with no media. Any thoughts or information? jpw

And you then wonder why they have their mailing lists configured to discourage this behaviour? ----- Reply ----- Gee, I thought what he was saying is that he thought that at least some members of this "busy community" would be generous enough with their time and knowledge to be willing to help a fellow hobbyist without demanding something in return (as many indeed are!)... As Fred mentions elsewhere, it works both ways; on several occasions a Google search has popped up a request on some list looking for a part or documentation that I happen to have, but when I saw what I'd have to go through just in order to reply I decided to pass... Even if there were indeed flamewars 25 years ago, that doesn't mean that we can't be patient, civil and even friendly today, especially with fellow members of a rather unique community and list of which the main raison d'etre is to share and help each other... m

Also, Kevin Murrell at TNMOC and I discussed MUMPS but I'm not sure what he/they might have. Since LCM has a working PDP-7, I was always looking for a copy of the original MUMPS.

How many addressing modes does the VAX actually have?

by krfkeith＠gmail.com

I've seen 16, 22, and 24 cited as the official number. The VAX architecture manual seems to suggest 24. If the number is indeed more than 16, how are they encoded? Seeing as how the manual says 4 bits are used for specifying the specific mode, and 4 for the register selection, and seems to imply that the operand specifier is always a byte long. Sorry for the potentially dumb question.
