Chroma Expansion Board: Firmwareby Sandro Sfregola  <firstname.lastname@example.org>
with David Clarke [21030085++] <email@example.com>
The CEB was the precursor of the CPU Plus (CC+), implementing the initial functionality of the CC+ as an add-on rather than a replacement board. The information on these pages is provided for historical interest; there will be no further updates or firmware revisions. See The Chroma CPU Plus (CC+).
The firmware is written in Motorola 68B09 Assembler and compiled with AS09 release 1.31.
Thanks to Frank A. Vorstenbosch for his good and freeware AS09 cross assembler.
The current release is Rev. 20.08 (Rev208.bin) of October 25, 2005. It fixes a system exclusive load bug in the previous release.
