I just acquired a KA640 VAX in a BA215 (thanks Josh)

working RF30 and one dead RF30 with failure code 300B(X). I don't have
copies of any manuals which list the error codes. I just figure at
this point that the drive is dead and there is nothing that can be
done to try to fix it.
You could/should try and run some diagnostics. Maybe they can print out
something more intelligible than just an error code?
The working 150MB RF30 is too small for a useful VMS
system although
it would be a decent size if I set up the system as a PDP-11 with an
M7554-PB KDJ11-SB CPU instead of the VAX KA640.
Be aware that no PDP-11 system knows about DSSI. There is one Qbus DSSI
controller that looks like a simple MSCP controller, and that one should
work fine. Any that exposes more of DSSI will be a non-starter with a
PDP-11.
