The <help> problem is on 1040STs with one meg of RAM, because the help page 
is not supported in the 832K mode. GBS Newsletter number 4 mentions this, but
has no solution. The simplest fix is to upgrade your memory to 4 (or 2.5) meg.
I did this with the JRI simm board. You will need more memory any way for
sounds, which take up lots of room on the system heap. Print spoolers
like Multispool and ram caches for ATM eat up RAM as well. Finally, many
programs just will not fit in the 832K space. Mathematica wants at least
3MB and even then I've run out of RAM with it. 

The 832K mode is kind of a kludge and should be avoided, if possible.
Features like the fading in of the first Mac screen are gone in the 832K
mode. Note that these features are only missing in the 832K mode, and if
you can do with less memory, they are there for the 512K mode.

There have been questions about sound with the Spectre here. I know I was
confused at first.  Programs with sound will work, have been working since
Spectre 2.3K. The only sound problem is the System beep, in the Mac's system
software, which will be fixed in Spectre 3.0. To have sound like the System
beep, but fancier, use SoundMaster. SoundMaster is a freeware cdev; beware
of it tho, as sounds can eat up a half meg of system heap very easily. Note
that some earlier sound formats, like the SoundMover sounds, are incompatible
with SoundMaster --this is what caused my problems, as I had only some of 
these incompatible sounds to test SoundMaster with.

If you use a lot of INITs and cdevs you may need to use a program like
HeapFixer (don't know the PD counterpart) to increase the memory allocation
to the system heap.

The 68030 board is still in development, as far as I know, and it will be
for Mega STs, not 1040STs. There is not enough room in the 1040 for the 8
simms, I hear. Latter there may be a 1040 version. GBS licensed TOS 1.62
from Atari for the board, so it would work with ST software.
