Subject: Re: Ultrix on an 11/730?
The 11/730 has an 'integrated disk controller' (it uses part of the CPU
logic IIRC), which conntects to an RL02 and the R80. The latter the same
drive as is used in the RM80, just that the RM80 has a rack of
electronics to link the not-quite-SMD interface to Massbus. The 11/703
talks driectly to the not-quite SMD interface.
IIRC, the stnadard configurations for the 'compact' 11/730 (one
half-height rack) were the CPU, R80 and RL02 or the CPU, R80 and TSU05
magtape. The latter just plugged into a Unibus slot in the CPU box.
The very first VAX I got my paws on in 1985 was an 11/730 running VMS 3.7.
It was a standard half-height rack containing (top down) a single RL02
(DQA1), CPU containing a TU58 tape for booting/upgrading and the R80 (DQA0).
Half a meg of memory too, which was the reason we ditched it in favour of
our first MV II (fruit) 'cos we'd rather fork the money out on a much faster
machine to run VMS 4.5 than pay for the extra memory for the 730.
Typing that's just made me remember the time I stripped and binned a TS11
tape drive :-/ And the VT52 that I skipped. And the VT180. And the Rainbows.
Curses!
cheers
