He connected the output of the card to the main board, whipped up a little code to generate the right frequency, and the nearly departed machine sprang back to life. Unwilling to wait for a replacement, cobbled together a temporary clock from an Arduino Uno and an Si5351 clock generator. It was then that decided to look at the heartbeat of the machine - the 24-ish MHz clock shared between the two processors - and found that it was flatlined. The usual low-hanging diagnostic fruit didn’t provide much help, as both the Z CPUs seemed to be fine.

After a full recapping - a prudent move given the four decades since the machine was manufactured - the machine failed to show any signs of life. Weird or not, all computers have at least a few things in common, a fact which helped home in on the problem with a Rainbow that was dead on arrival. But hey - at least it got the plain beige box look right. And machines don’t get much weirder than the DEC Rainbow 100-B, sporting as it does both Z microprocessors and usable as either a VT100 terminal or as a PC with either CP/M or MS-DOS. In retrocomputing circles, it’s often the case that the weirder and rarer the machine, the more likely it is to attract attention.
