Subject: 68000 assembly code
Message-ID: <GRAY.90Mar2153134@ghiggins.hpl.hp.com>
 
DEC recently announced the availability of Scheme->C, a Scheme to C translator.
I downloaded a copy of the code and would like to try and get it running on the
ST.  There's a snag, however (isn't there always?) --- there is a .s file which
deals with saving and restoring registers, counters, etc. (to facilitate
call-with-current-continuation) and some integer arithmetic overflow handling.
The code is in VAX assembler and needs translating to 68000 assembler.  It
*looks* like a fairly straightforward translation, but I could use some help in
ensuring that I get it right --- any offers?

I bought my 520 STE in december-89 and I'm very satisfied with it, except
for one thing. If I try to access a disk and it isn't inserted I get
the (CANCEL)  (RETRY) dialog box. If I put in the disk and click on
(RETRY) the machine BOMBS!!!!! (with bombs on half the screen). The same
thing occurs if I try to write to a write protected disk, remove the
write protection, and then click on RETRY.
 
Has anybody else experienced this??

Well the Timer C interrupt seems to be quite an important issue when trying to
achieve stable colour screen interrupts. Degas Elite subverts Timer C
completely during screen interrupts and Neochrome lowers the IPL level.
My own technique follows the Neochrome example and I believe is less traumatic
to the system but would welcome Atari's own thoughts on it.
None of our handlers change the timers characteristics though so I guess I'm
voting with Allan on this.

Message-ID: <27462@cup.portal.com>
 
My new Syquest drive should show up today so I'll be able to answer all
your questions.  I paid $899 for the unit, considering that it comes with
a case, the great ICD Host Adaptor, and all the necessary cables, etc.
for the addition $200 over the cost of the mech alone, I think its well
worth it (the Host Adaptor alone runs $125)  Reports from the field indicate
that the Syquest works fine with Mac and MS-DOS partitions, and thats why
I bought the unit, one platter for each OS.  The three companies currently
marketing the removable for the ST is Toad of Maryland, Carter of Ohio, and
ABCO in Florida - Atari's units is due soon, but again, too late and for
to much money...

Message-ID: <27463@cup.portal.com>
 
Mac emulation - Spectre GCR is the *only* way to go.  No messing with
                funny disk formats, Mac disks work out of the box and
                run at speeds faster than a real Mac Plus.  Aladin is
                pale by comparison.
 
Hard Drive -    If you want a great price and future expandability I
                suggest an ICD FaST 50meg drive with the Seagate 157N
                28ms drive inside - this baby can be had for around $650
                and comes complete - and upgrading is as easy as tossing
                in a new mech and buying a double crimped cable - the
                software is also outstanding.

Andy, I'm afraid your brain was _still_ a bit fogged.  415 is the area
code for the San Francisco area.  Perhaps you meant 413 (western MA)?

With the old hard disk driver, you can't.  With the new one, you can: I
believe you use a secno of -1 as a signal, and add an extra argument at
the end: the LONG sector number you want. I could be wrong.  By "new"
and "old" I mean 3.x is "new" and 2.x, 1.x or no version number at all
is "old."  Get the developer's documentation for the AHDI 3.00 Release
Notes: it has the straight scoop on this and much more.
 
I hope you are not assuming that a logical sector is 512 bytes; that's
no longer always the case, and people will not be able to use your tool
if you make that assumption.  Physical sectors, though, *are* always
512 bytes (as far as I know), which adds a level of complication when
you do physical-sector reads and writes.  In other words, get the docs
on this or you will probably get it wrong.

Did anybody get parts 1 and 2 of vault, or part 1 of George Woodside's
vkiller?  For some reason our site didn't receive them.  If someone
could email them to me it would be greatly appreciated.

        try again and include a US (snail)mail address just in case!
Wayne needs a mail server with TeX for the atari st. Anyone have an
address for him?
