Re: 80186
My school (Abingdon aka "Royce's") had a RM Nimbus in the D&T workshop. With Windows 1 on it and a rather early AutoCAD.
About 1 year later I (cheers Mum and Dad) had a 80286 based beast with 1MB of RAM. I saved up for a 80287 maths co pro so I could run ACAD on it. To be honest I had more fun reading Peitgen and some other bloke's fractal related shenanigans and attempting to replicate their results in GW Basic.
Then I got hold of a C compiler - cool and quick and bloody complicated. I went back to BASIC to get the results that I wanted at the time, in linear time. Before you smite me with righteous indignation, bear in mind that I just wanted results and not a cool paradigm.
