My question is: what is the LEGAL way to know I am running on an ST with
TOS 1.0 roms from a C program? The only legal way I knew of was Sversion,
but it returns 0,19 on both TOS 1.0 & TOS 1.2

All I have seen is de-referencing the pointer
	unsigned char *ROMS_YEAR = 0x00fc0018L + 3L;
which gives you the year of the TOS (on US and French tos it is 0x86), but
this is undocumented, and will surely break on the STe, since the Roms are
not in the same place!

PS: I want to know this for formatting a disk: if it is TOS 1.0, use the
TWISTER assembly code, if not, use the Flopfmt primitive with -1 interleave.

PPS: this is for my PD copier, flip, which detects and kills viruses when
copying disks, which is I found the best time to catch them!!! I never get
infected anymore.
(moreover it searches for calls to Flopwrt in the boot sector, catching
virtually ANY new boot sector virus to come)

PPPS: and do not tell me to pay to become a registred developper, all my atari
programming is public domain! :-)
