I was disappointed to learn that the RM05 was never supported, either.
Hmm. Yeah, I can't remember ever seeing 18-bit packs or support on the RM05.
We had several RM05's on kicki back in those days. Things needed:
* Include drive geometry etc. in driver tables.
So I assume Tops-10 don't have it in the tables normally. Which drives
did Tops-10 support officially?
* Make sure the controller in the drive (same HW as RM03 if I remember
correctly, but sitting in a separate cabinet beside the drive) has
the appropriate jumper installed in the backplane to enable 18-bit
mode.
I didn't know it was the exact same Massbus adapter for the drive. I
know that the RM02/RM03 have the adapter in the bottom of the cabinet,
while the RM05 have it in a separate cabinet (probably because the drive
itself takes more space in the cabinet).
And the RM03 is supported by Tops-10 then, I take it.
* Format the pack in 18-bit mode. We did that with a user-mode program
using the write-data-and-headers I/O function. I have the source to
that (short) program somewhere.
Hmm. I suspect the code for formatting an RM03 could be used as a
starting point?
Support? Don't think so...
