There is an implementation for NetBSD/OpenBSD. There has been support for
other operating systems but that code has been removed for legal reasons
(I need to rewrite some code). It should be able to load standard VAX, RSX,
PMAX and ALPHA images. I have used it for loading DSV100, DSV200, DSV250,
DSV300, some Xyplex Terminal Servers and a VS3100 with Xterminal software.

There is one known problem for the moment, it can't load my VS2000. I think
it's depending on a bad implementation of MOP in the boot rom of the VS2000,
all requests are sent in less that a second, all other implementation I've
seen sends requests with seconds apart. One solution might be to filter out
request comming to fast and just process the first. But it's not at top of
my list (and hasn't been for a long time).

The source could be found at ftp://ftp.stacken.kth.se/pub/OS/NetBSD/mopd.
