Yes and NT is my second favourite OS. Shame these people are no longer running the show and NT has become so saddled with terrible, burdensome middleware.
Used to use Fortran and punch cards on IBM S/360 clone (EC 1033)Burroughs mainframe, FORTRAN, IBM punch cards
Used tape to record my creations on MZ-821. Basic, hexa code of Z80 and Turbo Pascal.BASIC programs, hand entered, saved on cassette tape
At uni computer lab there was 80286 used as server for 10 other PCs with 8088, CGA card (4 colors) and no storage device (no HDD, no floppy, no tape ... nothing). They booted from that 80286 trough ArcNet (different HW and protocols than Ethernet) and used part of memory as RAMdisc.MSDOS on an 8088
It worked.IRQ jumpers, autoexec.bat, msconfig.sys ...
Had to buy SCSI adapter for my 1st CD burner to burn CDs at breakneck speed of x2.... manually installing drivers for a $240 CDROM that was NOT a burner!
Don't forget it could also run CPM with the |CPM command. Had a 464 with greeen screen before getting a colour 6128 later on (finally let it go when I sold it 5 years ago).I remember I had an Amstrad CPC 6128 back in 1985/86. It ran on AMSDOS (Amstrad DOS) with Locomotive BASIC. I bought various games on 3 1/2" floppy disks and messed about with writing code etc... those were the days [sigh].
GEM was also available on the Amstrad PC1512/1640 range of IBM compatibles (was included with MS-DOS 3.1 or DR-DOS as you had the option). MS-Windows was really nowhere to be seen in the UK (and Europe) until Win 3.0 (and above - 3.11 for workgroups being the outbreak version) made an appearence when 80386's were the norm. I was lucky enough to break my teeth on a large selection of home computers: Ti99/4 (not the 4a), Acorn Electron, BBC model B (at primary/elementary school), Amstrad CPC464, 6128, PCW8256, Commodore 64, Tatung Einstein, Sharp MZ700 and PC1640 ECD. Missed out on the Atari ST/Amiga/Archemides battle as went from PC1640 to a beige box 486 and then a Pentium 133, AMD Duron and onto one beige box PC after another.Color BASIC 1.0 on a TRS-80 Color Computer (circa 1978).
But my favorite of all time was Atari TOS (with GEM) on the ST's.
