UDA50's are not the fastest creatures either, IIRC the fastest disks for the 780's were non-interleaved RP07. That disk OTOH required 3-phase 380V 32A, even though i think it had Y-D startup.Yeah. No RP07s here, unfortunately. I have a number of UDA50s in other machines. They run very nicely in PDP-11s.
The controllers work OK, but you may hit the Unibus speed limit.Also be sure that you put the DELUA in the other unibus box or they'll compete much about the bus speed.
With DELUA it should be possible to get about 5Mbit/s (on 780) if it is on its own unibus.
