I have a VXT-2000 that I wish to use as an xterminal for the
vax 4000.  I went to the compaq website free area to get the
xserver images (VXT.SYS & VXTLDR.SYS or something like that).
However, the images seem to be bundled up in some wierd format,
not having the .SYS file extensions that I would expect.

Any ideas what they are?

Any ideas what CPU VXT-2000 uses?
