I tried to make a v2.2 for RL02 but it behaves the same as the DU-version of the v2.2. So it is NOT the driver. I jumped to conclusions here.
I don't have a real Unibus system with a UDA50 and a drive up and running. Another option is to hook up a RQDXn with the 11/03. But that is not done in a short time frame either. So testing on real hardware is not possible right now. /Mattis > /Bob > > > On 12/30/2015 3:08 PM, [email protected] wrote: > >> Great that we have a solution for BEVENT! >> >> According to the manual XXDP shall resort to the small monitor if the MMU >> is non present or faulty.
