Well, that's today. Scored a 10 MHz rated CPU, FPU, TCU,
plus 1 MB of 100 nS memory, and did 'a bit of testing'.

10 MHz passed with flying colours. Very rapid compared to
6. Panos 1.4 loads from GoSDC in around 7 seconds. Whoosh !
(which happens to resemble the sound that the power supply
makes when it loads ...).

One surprise. At 8 MHz, it's still not fast enough to keep
up with maximum speed double-byte Tube transfers, although
it does for single-byte transfers (and then 'just about',
probably). At 10 MHz, double-byte is also fine.

12 MHz : boots sometimes, but is unreliable. Must try 11
sometime, if only to that extra bit of confidence that 10
is actually okay ... :-)
