Here's a "nice" question for you ST people. It's about the blitter, of
course. I know you guys can "hack" and put a blitter in the 520/1040, and that
the MEGA, STe(?), and TT(?) come with one. But what are the blit sizes for
those blitters? Our "old" blitters are 1Kx1K and the new ones (which started
beginnish of last year) are 32Kx32K blit sizes... I hope SOMEONE CAN ANSWER
THIS! OH, ONE MORE important question. A programmer friend of mine told me
that ST's OS (1.4 in the 520/1040?) is/was CP/M with a GEM overlay? Is that
true? And, if you DON'T know what the heck you're talking about, PLEASE DON'T
REPLY, I'm sick of stupid people.
THANK YOU,

Jim, The underlying OS for the ST is TOS it stands for Traimel Operating System (if I spelled his name wrong forgive me) it is its own entity but from looking at the bios and xbios calls it seems to be losely based on MSDOS, probably due to GEM being a MSDOS application ported over to the Atari (and it also explains the compatabilties between disk formats). But it is not a MSDOS clone as a lot of the underlying structures (interupts and memory addressing) and it does not use loadable device drivers (all device drivers are loaded as TSR's). CP/M was used in the prototype of the ST but it was found to slow the machine too much so it was scraped. Thomas J. Arseneault INTERNET: arsen@itstd.sri.com SRI International

Blitters don't make sense in a 68030 system with burst transfers. Well, not much sense, that is. >THIS! OH, ONE MORE important question.

And, if you DON'T know what the heck you're talking about, PLEASE DON'T That's not correct. TOS is based on GEMDOS which is much more of a DOS clone than some CP/M derivate. GEM, consisting of AES and VDI, sits on top of it. ---------------------------------------------------------------------- Claus Brod, Am Felsenkeller 2, Things. Take. Time.

The ST's OS, which is TOS (Tramiel Operating System in the good old days, The Operating System nowadays (official name from DR as I read from csbrod?), Thirty-two Operating System (32-bit, geddit)) is from Digital Research, which wrote CP/M. While they were writing the OS for the ST, they based it in CP/M 68K, a version for the MC68000, and that's where the CP/M base comes from. Mind you, it's just based on, not real CP/M. -jp -- --- Jose Goncalo Pedro BITNET/Internet: jgp@fctunl.rccn.pt +---------------------------------+ UUCP: jgp@unl.uucp | Departamento de Informatica +----------------------------------+ | Universidade Nova de Lisboa 2825 Monte Caparica, PORTUGAL | +--------------------------------------------------------------------+

I never used CP/M extensively, but I clearly recall that the command-line
interpreter of CP/M was an immediate descendent of those of the traditional
(i.e. pre-VMS) DEC operating systems -- TOPS-10, RT-11, OS/8. I haven't
used MS-DOS extensively either, but I can use it in a pinch mostly because
it, in turn, looks a lot like CP/M. So, I suppose one could say that,
to the extent that TOS is based on MS-DOS, TOS is indirectly based on CP/M,
except that the window/mouse user interface doesn't look anything like the
user interface of either MS-DOS or CP/M. Just a bit of history...
