I beleive the historay can be traced back to the MCS8i
system. This,
AFAIK, never had disks, and never ran CP/M. But it's 8080-based and
amazingly it has a CPM-like IOBYTE at location 3.
It's not that the Intel development systems had a CP/M-link IOBYTE.
It's that CP/M has an Intel MDS-like IOBYTE. Remember that Gary Kildall
wrote software for Intel before writing CP/M, and that CP/M was written
to run on an MDS.
