That page I also found. However there disk gave errors and I blamed that 
on the different machine. A lot of the tuning also doesn't apply to the 
780. I tried again with an adapted version of your ini:

load vmb.exe
set cpu idle
attach rq0 vms44sys.dsk
attach rq1 vms040stb.rx3
attach ts bb-bt05c-be.tap
;attach cs vms044mup.rx1
set console log=logs/vms44.log

I used the tape found elsewhere, but just to be sure:

hvdkamer at obelix:~/vax$ md5sum bb-bt05c-be*
7fa6f5bfe2e49a1de37e7312e8ef9ae6  bb-bt05c-be.tap
7fa6f5bfe2e49a1de37e7312e8ef9ae6  bb-bt05c-be_vms_v4_4_c1986.tap


You say:


b rq0 /R5:800


But that is the not initialized disk? I tried:

hvdkamer at obelix:~/vax$ vax780 vax780.ini

I also got that from a different ini in my earlier experiments. This and 
another experiment at least seems do something :-).

I will try there code it in a virtual Windows machine, just to see what 
is different and if it gives some clues.

Thanks for the reply.
