Puts on Acorn hat.
That's right. The A3000 had an 8Mhz ARM2, while the A3010 and 3020 had a
12Mhz ARM250 which integrated VIDC, IOC and MEMC into the processor itself.
The other nice thing was the high density disk controller meant you
could write 1.6Mb to a disk (and thus PC 1.44Mb disks) whereas with the
3000 you were stuck with 800k / 720k DOS.
As regards transplanting the drive into a PC via a 2.5' adapter, I had
to do the same with the drive from a dead K6 laptop a couple of months
back. It worked very well.
