![]() Mission accomplished, but it was a bit exhausting.ītw. Having the files, I used 22DISK and the format AMP2 (SB180 has the same 40 tracks format) and copied the files onto a real (blank) diskette back. Now I was able to extract the files to the hard disk drive, then I changed the computer (going to my disk transfer PC with 22DISK). just creating a new entry in DISKDEFS would make it: What was missing ? How to transfer files from and to that image file ?ĬPMTOOLS to the rescue. My final goal was to copy UNIFORM (multiple disk formats and transfer utility) to this blank disk, but I got only a "sb180b30.image" file - which was in fact a binary unpacked IMD disk. Now, changing to N:, I was able to make a new blank diskette. VFILER was also present, so I was able to copy VFILER.COM to the RAM Disk with the help of VFILER itself, also DIR.COM and also FVCFX.COM (this program can format and copy diskettes). I didn't know the initialization program first, but after try and error, I found NDSKFX, just starting it with 'I' means initialize the RAM Disk (only after that, you can copy files onto it, if you know a copy command). This is really an adventure, also because of ZRDOS (or ZSDOS, as some told me).īecause there is no PIP nor COPY command for files, I was a bit helpless how I can transfer files on a new disk, also because my SB180FX has different floppy drives.īecause of the different floppy drive formats (A: = 40 tracks, B: = 80 tracks), I was not able to copy files from and to empty 40 track floppy disks.īut RAM Disk (Memory Disk) to the rescue, N: (and M:) is a default drive for the build in RAM Disk. While testing my Micromint SB180FX again, I was curios how I can transfer files from and to Micromint floppy disks. Related link points to the manual for the PG750-486. I didn't find so much additional information about the device itself, it seems to be a bit rare, even the original manual of the PG750-386 can't be downloaded anymore (but still for the 486 CPU version). There is no left space for additional drives, because only one 5.25 drive bay can be used: So I replaced it with a modded Gotek drive: Unfortunately this Canon MD5511 drive was faulty (the 5.25" part). ![]() The PG750 has originally a combo floppy drive with a 3.5" and a 5.25" floppy. You can't access the CP/M filesystem (2nd partition) with MS-DOS, but with Concurrent DOS 3.2, I was able to access both partitions at the same time: The original hard disk drive contained MS-DOS 3.30 and Personal CP/M 2.0 (S5-DOS) - these two OS can be selected after booting of the PC is done: So I am still looking for TIGA GEM 3.0 and Windows 3.11 drivers. But the TIGA card offers higher resolutions similar to a VGA card. It is very hard to find TIGA compatible software, mostly only ACAD 9 and 10 drivers. This portable device has a Texas Instruments Graphics Adapter (TIGA) named Higraph I, based on a TMS34010 chip. But regardless of it, it can be used also to play DOS games, at least EGA graphics compatible ones. Recently I purchased a portable PC, a Siemens PG750, which was in fact used as a S5 PLC programmer. I am desperately looking for the EGA Alpha version of Wolfenstein 3D, still. If you look for the VGA Alpha, try to search for WOLF1V.ZIP. You can search for wlf3dv10.zip, 1wolf3d.zip, W3D1-ASP.EXE, 1wolf11.zip, 1wolf12.zip 1wolf14.zip if you're looking for the several final versions 1.0 to 1.4. If you want to find these versions, take a look at the "related link" first. "Rated PC-13" is only displayed with a final version, too. Version 1.1, 1.2 and 1.4 gameplay will be displayed without any glitch/error, if started with both DOSBOX variants. (the vertical resolution seems to be doubled ?) This happens with Alpha and 1.0, if started with DOSBox SVN-Daum: ![]() This does not happen with the latest DOSBOX 0.74.3. This Alpha version has some visual differences in menus and starting screen, but only the demo mode and the episode selection was missing, in the level selection of the Alpha the easiest mode was not implemented, too.Īlso, I recognized the Alpha version and the final version 1.0 of Wolfenstein 3D will not run without a major display error with DOSBox SVN-Daum (the version with Glide support a.s.o.). I was looking for the Alpha version, but I was only able to find the VGA version of it. What is really interesting - an Alpha EGA version was also made ! Wolfenstein 3D was originally also developed to run with EGA, but they changed their mind and dropped support for EGA also a few month before the final version 1.0 was published.įor example it is possible to find EGA graphics sets in the game itself. was created only a few month before, but still running with EGA video cards. ![]() ![]() We all know Wolfenstein 3D, the first VGA 3D shooter game for the PC from Apogee. ![]()
