I'm new to this news group and the S-100 world so my appologies
in advance for what may be stupid or common knowledge questions.
I purchased an Imsai 8080 and would like to run some version of CP/M.
Should I stick with Imsai's IMDOS, which we know works? If CP/M is doable
What version would be the best choice?
Does CP/M need some sort of BIOS like the PC? If so where do I get the BIOS
source in order to burn an EPROM?
Any help, pointers, URL's, etc wouldbe greatly appreciated.
Thanks.

This is the S-100 world you've entered, not the PC world. The BIOS doesn't go
into an EPROM, and you don't buy the BIOS. If you can't find one written for
your EXACT hardware environment, which you usually can't, you have to write it
yourself. Then you have to incorporate it into a bootable image of CP/M and
then find a way to propagate it onto a bootable diskette.
That will require some study and some effort. Hopefully you're endowed with
enogh free time and interested enough in the related tasks to get that done.

You should add that it is a real kick when you finally get
everything right and the sucker actually boots and works!
All of my boxes that run CP/M run 2.2 built from the source
found at the "unofficial CP/M web site":

Finding a build environment is left as an exercise for the reader.
