XDX is a registered d/b/a in Berrien Co., MI since 1985.
The letters ARE the company name, a succession after SDS and XDS, not
the expansion Xeith's Dehisce X. (Where the first X is a Greek Chi as
in Chi-squares and the last X is the roman numeral. Dehisce requires a good
dictionary and is most often used in biology. It comes from latin and
means to split open. It is used in this context to refer to the major
divisions of my company's interest.)
Recent company developments include a Sigma 6/7/9 emulator running
CP-V on standard PC hardware. This was developed in partnership
with George Plue.
June 1987 NASA Sigma 9 Computer repair.
