Ha, the last one : what about "ST" itself ? "Super Tramiel" ?... (^_^)
No friend of mine, even ST users themselves !, could reply me.
I tried myself to find a correlation between TOS/ST and Atari names,
and failed.
If Atari gave a full name to their STs,
instead of strange capitals only,
I wouldn't have had to ask you for it !
Thanks.

ST Stands for 'Sixteen Thirty-two'
This is because the 68000 is a 16-bit processor, but uses 32 bit
internal registers. The address bus is actually 32 bits wide, BUT the 68000
only uses 24 of them, hence the 4mbyte limit :-(

Nevermind: its amazing what they can do with plastics nowadays.....
Yes it is, but in the first ST-manuals (the one from 1985) it says TOS is
for Tramiel Operating System. A few years later (1987) when Atari released
the pre-blitter TOS, the manuals was changed (and much improved, but still
not very good). It said TOS is for The Operating System. To be honest, I
don't think that was the original meaning, but since Atari wrote it, I
suppouse they may change the name as they like...
BTW have you ever searched the ROM for the word "love"? Try it out, there
is some info you won't get about Dave Staugas else... (try case insensitive).

So true, but again this has been subject to change by Atari. At the time when
mr Tramiel got the boot from Commodore and bought Atari Corp. There was a lot
of rumors about the Jack'intosh (which when it finaly made it to the shelves
was called ST). The ST was then said to stand for Sam Tramiel (one of Jack's
childs I think). Again the attitude of Atari Corp. have changed since then.

Insert own toughts here. The above is mine, and only mine!
Hypothetical situation ... what if I had an STe (that uses SIMMs for
its RAM). If I had the bucks, why couldn't I use 4MB SIMMS rather than
256KB or 1MB SIMMS?? If I stuck in 4 4MB SIMMS, that would be 16MB of
RAM, within the designed capabilities of the 68000 CPU!
So the $68000 question is ... why can't the ST use it? Is it power?
Physical size? Some design flaw? I WANT TO KNOW!!!

Well almost, the MMU is more of the problem than anything else.
In actuality, a Plain dough 68000 can access 2 to the power of 24 memory
locations...
NOT 4 megs but 16MEGS...Why Atari chode to do restrict the total addressing
range of the 68000 is beyond me. It certainly wouldn't have saved them
any money prodcution wise.
Thank God my Mega STE doesn't have this annyoing problem.
Ehhh?? Wha' do it say??? I hain't got no ST (YET!!) and so I can't look fer
my own self. Post, please???

>Just a question : does "TOS" really mean "Tramiel Op. Sys." or not ?
Actually, it came from (although doesn't neccesarily mean)
"The Operating System"
>Ha, the last one : what about "ST" itself ? "Super Tramiel" ?... (^_^)
While Sam occasionally claims the initials are his, they came from:
"Sixteen Thirty-two",
as in a sixteen-bit external bus, thirty-two bit internal. Hence also:
"Thirty-two Thirty-two"
for the TT.

Rick, I believe that the 4Mb limit is imposed by the memory-management unit
(MMU) that's used in the ST. I _think_ that there have been h/w hacks to
bypass/replace this but I don't know any details.

Lack of address lines to and from the MMU, but I did here of a German
hack that claims 12megs or some thing like that, the MMU is still used
to refresh the Rams, and with some other logic to switch the banks..

Ill think you will find that your Mega STE has the same 4 meg limit,
unless you are refering to the VME slot..

Simply use the os var _sysbase. It points to the start of the os header.

It says "Dave StAuGas loves Bea Hablig"
I'm not sure that I've got the case of "Staugas" right -- it's a few years
since I found the message. The reason the case is mixed is because the
bytes that make up the string read like proper 68000 op-codes. If you looked
at them with a disassmbler you'd think they were legit. code. Perhaps that's
how Mr Staugas got the message into the ROM in the first place!

You must be joking ! The 68000 uses 23 address lines plus Upper/Lower data
strobe and is therefore able to address 2^23 = 8 Mwords of memory - that is
16 MBytes. The 4MB limit is caused by the build-in MMU (and it can be circum-
vented - a friend of mine made an expansuion which allows 15.5 MB RAM in a
normal 1040/Mega ST).

Is he making the information availible or selling a kit?
