I don't know what I have. Next week an 11/730
shows up which I have
never seen "live". It looks like it has an RL02, an "R80" and some
sort
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.
of 9-track. It's two racks wide. We'll see
:-)
I understand there were microcode issues on the 730 which made booting
painful. I didn't realize there was a "fix" to the microcode.
From looking around the 11/730 boards (I am still
looking for the
printset..) there doesn't appear to be any micrcode ROMs in the
machine.
There's an area of RAM which I assume is a writeable control store. I
think all the microcode is loaded from the TU58.
