Need for re-capping is probable (also because DEC used so many
"quarternary ammonium salt" caps like Chemi-Con low ESR 105 degC types
in nearly all their power supplies).
I also saw that the DS3100 has a battery pack for RTC which runs the
risk of leaking and destroying whole PCBs when too close/not taken care
There were also pmax machines which refused to boot when the NVRAM
battery was drained, but I think they were using "Dallas" RTCs with
However, I'm prepared to do surgery on an offered machine if it's necessary.

Thanks, I'm interested in case no-one will offer a machine which is
I can assist of course, but NetBSD runs well in gxemul with machine type
3MAX, so you can easily create a disk image yourself.
BTW using gxemul we even have automatic pmax test runs now!
