The 3B1 had an MC 68010. I don't truly remember how fast the real
system ran. The emulated system seems to run more or less the same as
the hardware did, taking my poor memory into account.
The 5620 used the same processor as the 3B2, IIRC. There are emulators
for both (maybe done by the same guy, I don't remember). I don't know
of emulators for the 3B5 or 3B20.

It seems to me today's 2GHz processors should be
able to emulate a 3B (*3B
or not 3B, that is the question*) at a performance that far exceeds an
actual 3B. Is the instruction set definition and architecture of a 3B
available anywhere?
Just wondering. I did such emulations for 68K machines and Cray machines.

Hello All.
I have made a pre-installed disk image available with a fair amount
of software, see https://www.skeeve.com/3b1/.
Thanks for doing & making the disk images, was an easy start! Do you remember, ho to set up the system to have
four disk drives?
Cheers & thanks again!
I don't think it can support more than 2 drives. Certainly the emulator
cannot. I don't know about real hardware.
You can split a big drive into partitions when formatting with the
diagnostics disk, but I don't think that's what you're asking.
Sorry,
Arnold
