SpartaDOS Pro 3.3a, 3.3b, and 3.3c - 1994-1997

SpartaDOS Pro 3.3a, 3.3b, and 3.3c - 1994-
----------------------------------
The SpartaDOS Pro 3.3 versions were developed by Stephen J. Carden, based upon
a dissembled copy of the older (more stable?) 3.2c release from ICD.
-- SpartaDOS Pro Ver 3.3a 3-Nov-94 -- Added MUX support and MS-DOS Commands.
Highspeed SIO routines NOT included. Recommended for use in emulators
(especially Xformer) only.
-- SpartaDOS Pro Ver 3.3b 25-Dec-95 -- Has two different SIOV handlers, one
for the MUX and one for the MIO.
-- SpartaDOS Pro Ver 3.3c 1995 -- Looks at your system and by checking it
determines what CIO handler to load, and has MS-DOS command set. Black
Box, MUX, and MIO are fully supported, though none of these are required.
-- SpartaDOS Pro Ver 3.3c 19-Dec-97 -- the same 3.3c produced on a 16K ROM
cartridge by Video 61.
-- SpartaDOS Pro Ver 3.3d -- exists, but is not in general release

According to Lance Ringquist:
K-Products contracted FTe to develop SpartaDOS Pro 3.3 for exclusive use and
distribution with K-Products' BBS Express! Pro, to provide this BBS system
with the most stable platform possible. As Video 61 now owns the rights to
BBS Express! Pro, SpartaDOS Pro 3.3 is therefore now a product of Video 61.

According to Stephen Carden:
The SpartaDOS Pro 3.3 versions were never owned by K-Products, and are
technically shareware owned by FTe, although FTe had no connection with the
specific development of the 3.3 versions.
