They were (supposedly, given that it's not certain that any were ever sold) part of Acorn's ill-fated "Business computer" range[1], which didn't exactly meet with success - the styling was pretty ugly, and by the time they were made running all the I/O via 8-bit BBC hardware was just too slow in comparison to other machines on the market. [1] other systems included the ABC 200/210 (the "Cambridge Workstation") with a 32016 second processor, the ABC 100/110 with a Z80 second processor, the Econet Terminal, and the Personal Assistant. I got rid of all my RISC-era[1] Acorn stuff when I moved to the US - it never was quite as much fun to screw around with as the older 8-bit Acorns. I kind of wish I'd kept some of it now, though... [1] although I do still have an ARM-1 co-processor for a BBC, and a couple of ARM-1 ISA cards, and a Simtec Hydra multi-processor board set (but no machine to run it in, doh!) cheers Jules
