A bit of history (extracted from Tony Tebby's articles) and a screen shot.
The screen shot is of the SMS2 cartridge actually running from a USB stick on windows 7.
The odd thing about the SMS2 extract is Tony Tebby's assertion that it "never made it to market".
It must have done because there is a Youtube video showing an SMS2 cartridge booting up in an
Atari ST. (Type SMS2 in the Youtube search box to find it)
SMS2 also ran in an Atari Mega STE with a QVME graphics card to give high resolution displays.
It seems that Tony Tebby was not particularly keen on tha addition of a BASIC interpreter to make SMSQ/E, describing it
as both, a "QL nasty" and as purely retrospective and not furthering the Domesdos OS principles.

SMS2
When it had been well established that Domesdos did work reliably and significantly more efficiently
than conventional rnultitasking syslems, I set about writing version 2. The interface was cleaned up to
remove 'QL nasties", which meant that there was no SuperBASlC.
This SMS2 (Small Microcomputer System V2) was hardly any larger than the original Domesdos (QDOS?)
core and, typically, important operating system calls were 30% to 100% faster, as register handling was
optimised for the more complex calls, rather than the simplest, and the code was crafted more carefully.
There was no permanenl user interface program but, whenever there were no jobs in the sysiem, a
default application (Job 0) was started
This syslem was implemented on the Atari ST monochrome system and feasibilily trials were carried
out on a small number of embedded systems. lt was never made available commercially on "standard"
plalforms and no project using it ever made it to market.
SMSQ was SMS2 to which SuperBASlC compatibility was retrofitted. lt was inlended to provide a QL
compatible operatrng system for various QL emulalors. ln general it was much faster lhan QDOS
lt was purely retrospective and did not further the Domesdos style OS principles.
SMSQ-E
SMSQ-E was SMSQ bundled with the slandard QJUMP extended Environment.

A BRIEF HISTORY of SMSQ/E
Le Grand Pressigny, FRANCE - Tony Tebby
"Incompatibilities & Improvements, Bugs & Features"
"Was It All a Terrible Mistake?" I knew right from the start I should not do it, but so many people were asking for SMS to come out from under its covers that, in early 1992, I outlined a strategy (with Miracle Systems and Jochen Merz) to make a "QL compatible" version of SMS available.
