I always found the Rainbow architecture kinda cool actually, when running

um, I have rainbow A & B models, and the 8086
is on the main logic board,
not on an add on card.
Sorry for my imprecision. You are right, it wasn't an "add-on" card, the
context for the incorrect remark was the Rainbow described as a CP/M
machine, with the 8086 "added on" to it. Obviously not so literally as I
said.
(Logically-speaking, the 8086 was an accessory to the Z80, whivch owned
all the peripherals.)
