Jim (and other cctalkers), Grab a copy of the SIMH Altairz80 simulator from http://schorn.ch/altair.html and the zip file of my cpmplus for the CompuPro Disk1 controller from the Other Operating systems link at http://schorn.ch/altair_5.php This supports IMD disks in BB II 1.4Mb (1024byte x 9 sector) format.

If you need to support other CP/M disk formats, the BIOS source files and submit files to put them together are in the A1: directory on the hard disk image. There's also CP/M program to make IMD disk images natively under CP/M-Plus in A3: (it will span the IMD file across multiple floppies if the image file is too large). I used this to copy all my 8" floppies (including BB II ones) to IMD images. Tony -- Tony Nicholson <tony.nicholson at computer.org>

Can Windows 98SE run on an Intel I7 with SATA hard drives?

by COURYHOUSE＠aol.com

just for grins I took on of the SMECC e-machines out of back room and fired it up... yea Win 98 SE running just great! last time I used this particular old office system was '07! heh it has a 4 gig hardrive Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 2/4/2016 11:53:40 A.M.

Nope, these are MS-DOS apps that require access to the UART registers. Anyone who thinks that MS-DOS is dead and buried doesn't have to work with some of the vintage (but still in use) technology that I sometimes deal with at work. I am certain that there are many on this list whose vocations involve decades-old hardware that is still in use. Dale H.

Mentec manuals

by Paul_Koning＠Dell.com

I was looking back at the discussion on what Mentec actually owned, back when it existed. The discussion on the list suggested that Mentec had a license but did not actually own the IP. It seems an odd arrangement that doesn't say much for the business skills of those making it, but I suppose it's posssible. I found that there are some RSTS manuals at www.computinghistory.co.uk with Mentec cover pages. Among other things, a free for the download RSTS 10.1 internals manual, over 600 pages of good stuff. The cover has a Mentec logo but no other ownership clues. I was hoping to see the copyright page to find out whose name appears there. Unfortunately, the scan omits the copyright page. Does anyone have any manuals from Mentec? If yes, does it say "Copyright ... Mentec"? Or "Copyright ... someone else"? paul

Can Windows 98SE run on an Intel I7 with SATA hard drives?

by radiotest＠juno.com

At 08:08 AM 2/4/2016, Liam Proven wrote: >But NT is a better OS in every important or material way. It is unusable in one important way. This thread began as a discussion of running serial port terminal emulators on a PC. At work I still use some MS-DOS programs (admittedly not terminal emulators) over serial ports. For my purposes (setting up a variety of vintage specialized hardware over RS-232) NT-based operating systems are sometimes unusable because they present the application program with a virtual serial port, and MS-DOS programs running under those operating systems cannot read from or write to the UART registers. Some of the setup programs for that vintage hardware were written before the mid-1990s and access the UART registers, so I have to run those under Win98 or earlier. I have a portable MS-DOS 3.3 machine that I use to set up that vintage hardware. Dale H.

Can Windows 98SE run on an Intel I7 with SATA hard drives?

by jnc＠mercury.lcs.mit.edu

> From: CuriousMarc > Needless to say, you'd only boot to this Windows 98 for retro-computing > purposes. BTW, are you indicating that Win 98SE _in general_ should only be used for retro-computing, or only Win 98SE _in the particular configration you described_ should only be used that way? Because, if the latter, I happily use Win 98SE on most of my machines, for the vast majority of my work! Of course, I don't need to run the latest and greatest uSloth bloatware^H^H^H^H^H^H^H^H^H applications, so they fact that they probably won't run on the older Windows (What a shock! You don't think they would by any chance want to encourage people to pay them a large pile of dineros for the latest and 'greatest' version of their OS, do you?) is not a problem for me. The biggest issue, actually, for me, is that the latest Adobe Reader which will run under Win 98SE is 6.0, and that doesn't support some of the latest PDF's (in particular, encrypted ones). Noel

ISO: VAX-11/750

by derschjo＠gmail.com

So, I figure it's unlikely, but I've been jonesing for a "larger" VAX and I'd like to track down an 11/750 (or an 11/730). If anyone out there has one for sale trade (in any condition apart from "pile of slag"), let me know. I have DEC and various other gear for trade. Thanks as always! - Josh

BC11A Cable ends

by ggs＠shiresoft.com

I just received the BC11A-T variant boards (the ribbon cables come out the ?top??yea not imaginative naming) this afternoon. I inserted a couple of the ribbon cable connectors on the board and everything looks great! When I have some time (probably in a couple of weeks) I?ll fire up my 11/40 (to make sure it?s still working after all of this time) and then re-cable it using cables with a pair of BC11A-T ends and some ribbon cable. I?ll run memory diagnostics on it for a while (I have 128KW of memory on it split between two racks, so this should be a good test) and see how it does vs with the ?standard? BC11A cables.

AIX for IBM system 370

by lyokoboy0＠gmail.com

I have been messing with the Hercules emulator, and have really been wanting to take a look at ibm AIX, and get a working install on an emulated system 370. I have found no mention of install media or disk images of a working system for download online. Is there a good place to get the install media?
