hmmmmmmm - interesting thing is - that I don't think there's that much stuff -
the system is configured as follows

1 x RD53
1 x TK50
1 x RD disk controller
1 x TK50 controller
1 x KA630 motherboard
1 x 4 Mb memory card

That's it so far - as an experiment - I tried to get one of the RD53's to spin
up at a constant speed on a power supply from an IBM RT Model 135 (Read as
*HUGE* power supply) - and it exhibited the same behavior - spun up - and immediately spun back down.
