Forgot to add that there are partial disassemblies of some of the Cromemco firmware (for the 16FDC),
assemblers (with documentation), etc. on my Web site (http://sites.google.com/site/oldcpusrus).  Look
in the "CBIOS boneyard" section.  Also, Marcus Bennett's site is an extensive collection of things
Cromemco.  That link, and several other valuable on-line Cromemco resource sites, can be found on my "oldcpusrus" front page.

Hope this helps.
