I assume T11 also provide Q-BUS as chip interface, so probably two different
"CPU+bootstrap ROM" cards could be designed and used with same motherboard that
would provide all peripherals.
from DEC directly put out.
The T11 was more like 8085, 8086 and Z80 as the bus is configureable
for 8 or 16bit width and static address or muxed for DRAM (with refresh)
and the microcycle could be configured for system application from
a minimal to maximum.
The KXT-11 cards would be an example of a complete(minimal) T11
system on a Qbus card with full qbus expansion (Q16) for memory
and peripherals.
