My first real computer was a also a PS/2 Model 80! Mine came with a *MASSIVE* 100 MB ESDI hard disk with DOS 3.30 installed.I remember using a PS/2 model 80 to run OS/2. It had a full graphical desktop, all kinds of software ran on it, editors, compilers, word processor, graphics, tcp/ip, etc.. It ran on a 386 cpu and had 8 MB RAM. My memory told me it had a 486... but wikipedia says a 386, so I think my memory is wrong. Of course that was before web browsers were a thing. The machine itself was built like a tank and very expensive, like all their kit. OS/2 had real multi-threading and pre-emptive multi-tasking, but unfortunately for ibm MS already owned the PC market and ibm had already lost control and was really unable to break in, especially given their daft policy to begin with of trying to sell you a very expensive, non-standard MCA bus PC to run it on; I think it took them a year to two before they decided to allow OS/2 to run on non-MCA PC's.. The OS/2 software was good though, windows didn't really catch up technically until they brought NT out, or maybe later than that.

Software seems to expand to fill the available hardware capacity... there has to be a "moores law" type rule for that.
At first I thought I'd been cheated because when I ran dir it showed that the C: drive only had 32MB. Eventually I discovered that that version of DOS could not handle such large partitions, and that I would have to create four partitions to be able to access the whole disk.
Happy days!
