Subject: [DECtec] disk loading success


  Then, armed with confidence from that success, I dismounted and
unplugged the RA90 from the VAX-7000 and plugged it into a PDP-11/44
(2MB, FPP, CIS, UDA50) and booted it.   That worked too! =)

This makes me really want to get my 11/44 working...and get the UDA50 I'm owed.

I'll also need an SDI drive and cable...or 3.

  (Now of course I could do the same with a Qbus PDP-11, with a KDA50
SDI controller.)

  My first desire was to do the actual RSTS/E install under simh on the
VAX-7000 directly to the raw device, but that crashed for reasons
unknown.   Mark Pizzolato told me that it was unlikely to work, so I may
not investigate that any further.

  Tonight, I will likely put together a VAX4000-700 in a BA440 chassis
with DSSI drives.   Into that I will put a KDA50 (I have an S-box KDA50
distribution panel) and use that in the role of the VAX-7000 for this
type of stuff in the future.

If I could convince you to spare an SDI disk, I could have you write images for me! ;)

  I am looking to have MORE SDI-interfaced drives, not fewer. ;)   I just
lost one the other day, if you recall.
