Good to hear. Any source of these sticks ? Ebay maybe ?

Yes, I see 4 x 4 MB sticks in the slots, plus the 8 MB onboard one
as you say, that makes 24 MB. True, it runs OK, I have a 1 GB
Quantum disk with VAX VMS 7.2-1 on it.
I have some other disks, an RZ28 for example, but I still have to
figure out the proper SCSI termination, and the ID-s of the disks.
I still would like to have a bit more memory, maybe some 16 MB
sticks would be ideal.
I have a handful of 72-pin ones if someone wants to swap...

Thanks, Dave. What do you mean about the issue of shipping to Au. ?
I don't think there is a problem, I have sent stuff from here to the
US with no problem. Cost of shipping should be low, as the weight of
these sticks is light.
