I read
somewhere that it could be converted to a 11/53 with a minimal
effort. How much trouble?
Rip out the CXA's (16-port serial boards), add a
disk and/or tape
controller, and perhaps some memory. Off you go. The heart of
the DECserver 550 was/is indeed a barebones /53 CPU. Which comes
with 512KB RAM on the CPU card, and its console serial port.
I don't believe you are "ready to go" after this mod. I seem
to remember that the ROMs on the DS500 use special boot code
and that they need to be replaced to be a normal 11/53. I
saw some posts on one of the newsgroups from someone who had
done it.
