Not that I can claim that I know what I am talking about...but...
From a early article in Byte on the NeXT I seem to remeber the memory
that the DSP has is quite limited. I would guess that the 68030 has
to swap in new data all the time.
Isn't the *only* reason it was installed was for 'CD' quality sound... wasn't
the 030 supposed to handle the tasks?
Working on release 0.9, I am amazed every time I log onto it... just wait
until it gets to 1.4...(isn't that the magic number??)
Another thought: How many songs do you want to hear concurently?
PS: see you on comp.sys.next
Since I don't think Mr Jobs will be able to reply I felt someone should
offer a little reality.

I have seen things like this, but don't remember where. I have used
a 1040 ST and now use Mega ST2. I just tried an experiment...
remove floppy from drive A:.
drag icon for a file from drive A: to drive D:.
get the CANCEL-REPLY dialog box.
put the disk back in.
copy proceeds just fine.
Does this sequence this give you bombs too?
It seems to me that the times I have had trouble have been while
running application programs and I have had both bombs and program aborts.
I try to keep my drive a: loaded most of the time.

Subject: G++, what files do I need?
Message-ID: <4792@jarthur.Claremont.EDU>
Help! I have the G++ compiler sitting on my hard drive. What files are
actually necessary to run it? Do I really need the hundreds of files
contained in the g++-lib.zoo and g++-lib2.zoo? Can I just get away with
g++-gnul.zoo?
I'd like to get this working, but 400+ files seems a bit excessive.
(please respond via email)
Thanks for any help.

Message-ID: <16000017@ux1.cso.uiuc.edu>
Anyone try out Gemini yet? I run Gemini.prg after booting
with either AMCGDOS or GPLUS and get two bombs...???
Anyone got it to work want to comment? I tried removing
every auto prg and acc save amcgdos and shell0... No luck.
Went through the configs... set it for drive C: still
no luck.
Damn, I really wanted it to work... Is it any good in
a 1040 anyway? (Memory usage?)
Thanks for any tips

Cache sizes that small won't do anything. Expect to give up at least 200K for
an 80 meg hard drive. I'm unfamiliar with how the numbering works using ICD's
latest and greatest, so you'll have to interpret 200K to whatever those cat-
egories mean (they seem redundant to me).
Also, your Newsgroups: line is set to your Email address; please try 'n fix
that, as it can make replying a pain.

RE: Cheap way to hook SyQuest to 1040ST
I am using SyQuest HD now with my TUBO16/MEGA4 but the haed disk I have is not
TOAD File but an ATARI MEGAFILE 44. Yes It is available in Singapore and not
that expensive too. Comparing to the bare SyQuest 44 drive which selling at
S$1450 with 1 cartridge I bought my Megafile 44 and 1 44 Cartridge for S$1800
(US$1.00 = to S$1.85). It comes with extra LCD, Power supply plug and 50 pin-
SCSI as well as bracket for installing another 3.5" hard disk inside the case.
I will put my CONNER 100MB drive (I paid S$1200 for this one)into it. Drive is
very well made (I open up the drive to have a close look at the heads and voice
coil which make funny noise during startup but not as loud as the Seagate 277R
-1 in my Megafile 60. It look durable enough and the head is park into a plas-
tic prong to prevent any movement during transporting the drive. The top cover
of the drive is fixed with only 2 small screws. ICD HDRATEd is 28ms similar to
MEGAFILE 60. Drive is much cooler than Seagate therefore I deciced to put 15OHM
3W resistor to lower the fan speed/noise down. Unhook it from Atari SCSI>DMA
card and connect it direct to my Mac Plus with home made cable(per instruction
in Spectre GCR Manual) then format a cartridge with CMS HD utility version 5.3
or 5.5.3 The cartridge will be recognized by Spectre and even boot up with the
System/Finder written with Mac Plus. Macintosh will not read the cartridge if
it is formatted under Spectre. With PC-Ditto (Disk version) I can not boot the
PC-DOS from partition C:. PC-DITTO normally doesnot boot DOS if the HD is set
to AUTOBOOT with ICD HD Util or Atari AHDI. Although I could get my MegaFile 60
to boot PC-DOS from C: partition with Supra HD Autoboot, Supra Autoboot does
not help in the case of Syquest 44 Drive. I will experiment further with MS-DOS
4.01 when I receive my SuperCharger from Beta System Computers AG. hopefully by
next week. (Beta System supply MS-DOS 4.01 with their Supercharger and insisted
that I should use it to get the full performance). I am now using PC-DOS 3.2 as
I found it to be more stable under PC-DITTO than PC-DOS 3.3 or MS-DOS 3.30B.
I will report my finding to the net in due course. BTW SyQuest 44 MB Cartridge
is selling at S$190 here. S. Sujarittanonta, School of Architecture,

The real answer is you dont. And this is why.
The use of bit 3 is/was really to get to sector 0 and maybe 1 and 2.
(1 and 2 might contain a list of bad blocks). After this, very limited
area, it is expected that partitions will cover the physical disk.
TOS partitions can then be accessed by drive and offset.
What about Spectre and Minix partitions? Then you need your OWN driver
that will access sectors as a long absolute value. Thats what Spectre
and Minix do.
