We used to run "Spinrite" overnight on a bench-full of machines with 40MB MFM drives ST-506 duel ribbon interface.

Of course we had to partition them as two 20MB volumes, DOS 3.3 could only see up to 32MB.

I think those machines had a CPU clock at 10MHz, there was a little switch at the back to reduce it to 8MHz if things got too fast.
