Picked up a
DEC VT103 with an empty cardcage and I'm trying to decide
what manner of Qbus based system to put in it...
I understand it's possible to upgrade the backplane to 22 bits -- how
is this done?
I currently have a MicroVax 1 CPU, an 11/23 half-height CPU, a few
misc serial cards and the like, and a nice Emulex ESDI controller in
my box of spares... I'm worried about power consumption, though.
Anyone else hacked together a system like this and have any
recommendations for hardware/software?

Power is DEFINITELY VERY limited - 16 amps for the 5 volts including
the video display card!!!!!!!!!!!
An M8186 is VERY possible. Use a DLV11-J strapped for the console
port. If you have the adapter
card to switch the terminals for port 0 and port 3, this makes it easy.
That also allows port 0 to be used
for a serial printer.
How much power does an 11/93 CPU/Memory board use?
