Dave has nowhere to stuff a ROM. The KDJ11-A board
is dual-height and
is a CPU only, no peripherals (yes, in the
mini-computer world, boot
ROMs aren't always integral - if you have a front
panel, you don't
"need" ROMs, even if they are handy for fast
startup).
Ah, OK. I wasn't aware that you couldn't use an
onboard ROM on a KDJ11-A. What's that empty socket in
the middle for then?
Well, at least the PDP-11 can load bootstrap code from
ROM. On a Prime it is all handled through the VCP, and
bootstrap code has to be loaded from floppy. (slowly).
