Assembly docs for Zenith/Heathkit Z-150 PC compatible ??

I have my original Zenith (ZDS) Z-150 computer, which was their
answer to the IBM 8088/86 PC. This was also offered as a kit
from Heathkit (as the H-150?) in the mid-1980s.

My Z-150 currently won't start up, with lights stopping in the BIOS PROM
startup sequence. Does anyone have the equivalent Heathkit assembly
manual(s) and drawings for this system? Or are there similar systems
around that board swapping might be possible?

What is somewhat unique about the Z-150 is that there is no motherboard
as such (unlike all the PCs and Wintel systems), just an ISA bus and
the CPU on its own board. A idea similar to mini- and bigger computers,
but alas, except for the a few exceptions such as S-100 systems and the
Apple-II, an approach that never caught on in the so-called "PC"
series that have dominated since the mid-1980s....

Just curious. Thanks. Regards, Kevin Anderson
