I was able to buy it for a very good discount at the time because I was working for a DEC distributor. Its first hard drive was 5 MBytes.

It ran both CP/M 86/80 and MS-DOS. Originally I equipped it with an amber monitor but later I replaced that with a color monitor. This system could display 132 columns by 24 lines of text.

Over time I upgraded things to the point where it had an IBM-compatible 3.5-inch floppy drive, 20 Mbyte hard disk, a 286 processor with 287 floating-point co-processor, 1 MB RAM card, and a vertical floorstand.

Oh yes, it was running Windows version 3.0 using a serial Microsoft Mouse. (Although I don't have the computer any more, I still have that mouse).

For a while I was one of the top Rainbow technical experts in the country and DEC used to refer people to me for help.
