It's the
11/44 (a much later machine) that has odd fans -- 35V 70Hz or
something. They run off a transistorised full-H driver circuit in the
PSU, so they can be run off the backup battery.
That's the one. I guess I should have paid more attention - I have an
11/44, but I've never fiddled with the fans. I think I'll put "check
and clean 11/44 fans" on the list of summer classiccmp tasks.
OK. So... that makes finding at least one H720 more important.
I have at least 2 of them, but neither are spare (not to mention the fact
that (a) they're the 230V version and (b) shipping would be expensive).
One runs the RK11C on my 11/45 system. The other is part of a DX11 which
I really must get round to investigating.
