It was usable enough that Acorn sold a PC Emulator for the Acorn
A305/A310 -- the original, first-series Archimedes with 8MHz ARM2


I used it on my A310, in 1988/1989, to do real work in QuickBasic 3.0,
brought home from the office.

It ran at something around 2-3MHz as equivalent to an original 8088
PC, but with a much faster screen and hard disk, so overall
performance was good and quite usable for MS-DOS stuff.
