  • @SomeGuy said: If you load a TSR before Windows 9x starts, and then start Windows (you can still start Win9x by typing "win") that TSR will keep running in the background. That is very useful for devices that only have DOS drivers. They still wor…
  • It is indeed a beauty. I remember the tremendous kick I got out of building my first DOS/Windows PC (back in the '90s) - a veritable beige monster (tall tower!) - just a little bit slimmer than the MicroVAX II that I used at work. Have rebuilt/upg…
  • First machine I wrote code for was an ICL mainframe - programming with FORTRAN on punched cards (gaargh!). Then I wrote some machine code (that's binary, not assembler) on a Research Machines Z80 box of some sort (uurgh!). But programming first b…
  • @TxSnipper said: 1st computer was a TRS-80 Model III, 64 Kbytes Ram w/ 2x 5.25" floppy drives each managing blazing 186Kbs on each floppy. working at a blazing 1.86Hz (yes Hz not Mhz) on a Z80 Chipset CPU. Are you sure you didn't mean kHz…
  • The "related link" (not easy to spot on that page) is: http://www.z80.eu/downloads/IBMPC-UCSD.zip
  • Is this not viable for the IBM? http://www.z80.eu/blog/index.php?entry=entry170826-120000
  • Ok - that was weird: In the manual the examples are missing texts (something odd going on with boxed-out texts?) Not seen that before in a PDF.
  • Have you tried this resource? https://archive.org/download/Lotus123OLD It appears to include a version called "Lotus-1-2-3 v4-01 - English - Win3x.zip"
  • Has anyone managed to find any PDF manuals for this yet?
  • Really nice article, SomeGuy! Helped me to decide which one to install in which VMware'd version of DOS for my little tech museum.
  • This was fun (not) to install under VMware. It turns out that the INSTALL disk (or SETUP disk if you are using a different source) really doesn't like the VMware IDE hard drive emulation. If you use that, the installation floppy's boot code simp…
  • Thinking about it... you can bet your bottom dollar that the Microsoft PS/2 Mouse drivers are all looking for the most obvious DOS feature first (which is the DOS version number) and hence not testing for PS/2 mouse presence at all because it is "un…
  • Yep, SomeGuy, you are right - in fact, had the "Edit-timeout" not occurred, I would have corrected myself (One hour of editing is way too short for me! I spend too much of it verifying things) So, yep - there's no need or benefit in layering a…
  • As an after-thought, if you really like a challenge, there may be a way of fooling Windows into thinking the CTMOUSE (do a search for CuteMouse and download), is actually its own driver, by renaming and injecting one of the CTMOUSE files to replace …
  • SomeGuy's comment is correct if you are using MS-DOS 3.3 or later. Before that e.g. with MS-DOS 2.2, I can confirm that even this trick won't help you. I've tried (and posted about the attempt somewhere else on this forum). The PS/2-aware drive…
  • Fully confirmed: my (now corrected) Delphi-written version checking code, when running on Win95 OSR2.1 Service Pack C (which I actually use occasionally) is now correctly reporting version 4.3.1212 as it should do - so I'm a very happy bunny.
  • Some interesting new information has come to light: This is courtesy of the GetVersion and GetVersionEx documentation within Visual Studio 6.0. It turns out that the build number for Win9X duplicates the major and minor version numbers in its up…
  • My curiosity stirred, I decided to do a little experiment. I extracted the Kernel32.DLL from a couple of the CAB files on the ISO (which are correctly dated, but of a different size and date to the installed one). I used these to ensure that the…
  • I'm a little suspicious that it is more than: "a bug that was later corrected". The GetVersion routine is a Kernel32.DLL function. Whilst the Kernel32.DLL file in the system folder has a version stamp of 4.10.99 (like all other files in this OS…
  • @SomeGuy (again, again) Yes - vanilla MS-DOS 3.3 with a PS/2 MS-Mouse works fine under VMware - that I had already established before my experiments with MS-DOS 2.11 (indeed it presented no challenge at all ) Ironically, I thought putting Wind…
  • @SomeGuy (again) Good point about the PC-DOS 2.X being the more appropriate baseline. I'm going to have to work a bit harder on getting my "Museum Curator" badge! Don't really know why I started sieving through all the OEM versions first: espe…
  • @SomeGuy Thanks for the driver - will try that later today. Odd thing regarding the banner: I did a binary compare off all three system files (IO.SYS, IBM.SYS and COMMAND.COM) in both snapshots, the one with the banner and the one without. There…
  • The config.sys was the same (comparing them via VM-Snapsots). Also the command.com, and the two DOS system files are identical in binary. In fact I could discard the Autoexec & config files, and it wouldn't change the fact that one shows AT&am…
