I had one of those, my first ever "PC", it cost me £400 secondhand.
It was a real badged IBM with two 5.25 floppy disk drives and a mono "green" monitor. Worked in DOS only. Had to keep swapping floppy disks for different programs. The advantage of two drives was that you could leave the O/S disk in drive A all the time.
I started off with an Atari, then went to a Commodore Plus 4, followed by a Commodore 64 and finally a Commodore Amiga. I think I may also have had one of the first colour printers, an OkiMate 20. It had a "use once" plastic type ribbon which made three passes, one for each colour. This was used on the Amiga but I managed to find a company who supplied me with an EPROM for the IBM. All I had to do was switch the Eprom on the printer to use it with whichever computer I wanted a print from. Although I don't have the printer anymore I do still have the Eprom's.
If IBM had had the same foresight as Gates and decided to develop its own operating system then Microsoft (in its present form) would never have existed and computing today could well be very different.
