[comp.sys.dec] RM80/R80 on VAX 11/730

Hi,

I recently acquired an RM80 for my VAX 11/730.
To use the RM80 with the VAX 11/730 I removed the disk drive (R80) from
the RM80 cabinet and plugged it into the IDC controller on the 11/730.

After reformatting, it works fine, in fact there is not a single bad block
on the whole disk.

Sometimes when I spin up the disk the fault light comes on.
This is not a serious problem since it is cleared when the 11/730 trys to
boot. Pressing the fault switch when the fault light is on causes the front
panel to show the FAULT and STAT1 lights. According to the 11/730 handbook
this means "Read Write Diagnostic". Can anyone out there who has a copy
of the RM80 service manual please tell me what this means and how to
fix the problem.

BTW, If you want to speed up your 11/730, replace the 44.444 meg xtal on
the WCS module with a 47.9 meg xtal. Everything (IDC, UNIBUS, FPA, CPU)
should still work fine. It makes for quite a noticable improvment.
