I am hoping to try and hook up an ibm compatable 1.44 meg 3.5 or an
ibm 720k 3.5 floppy to my 1040ST. I would like to hook it to the internal
drive connections, or possibly to the external drive port. Does anyone
have the pin outs for the ibm drive and/or the internal st drive, if
different. Any hints or suggestions would be appreiciated...
Thanks,
Brian

Where can I get the latest version of CACHExxx.PRG? Does anyone
have any comments on this or other caching programs? (Ie. any
problems using them with partitions >16 meg or any comments
about their usefulness.)
Is this program public domain or do I need to shell out $$$ for it.
(I'm willing to do that if it is a useful program.) If it is not
in the public domain, what info do I need to give my dealer so that
he can get it for me?

Okay --
I don't want to generate any controversy re: the GEnie uplink thing,
which was admittedly not handled well last time around.
It looks like there's an okay on the GEnie end for a gateway to
GEnie with the following:
1) 2-way note throughput. (see below for more).
2) email
3) *No* copyright hassles (see below)
The last such uplink, as you'll recall, was 1-way, no email, and while
GEnie was accused of copyright hassles, it really wasn't that way.
Okay, on #1:
2-way notes. Yes, this can be done. However, there will need to be
experimentation done, because GEnie's notes paradigm is different than
USENET. Also, GEnie users will require some training in the customs of USENET;
for instance, quoting from previous notes when making comments,
signature lines -- all the stuff you really only learn by *reading notes*,
and by reading the ever-helpful How To Be On USENET materials that come with
the news package.
We have one or two dim flickers of ideas for how to resolve the notes
paradigm problem (suggestions are welcome).
We also want to make certain we do not flood USENET with low-signal
high-noise notes. Hence, we won't be hooking straight to the Atari ST RT
on GEnie, where the note volume would overwhelm USENET. Instead, it would be
to an experimental, controlled, limited-access area, where people who don't
understand USENET customs & protocol don't get their notes posted here.
(Probably at the start, the best way, especially for testing purposes, would
be to grant access to people who are already on USENET on the GEnie end.)
On the GEnie end, notes are concentrated by broad subjects
("TT", "Hard Disks", etc) into "topics", rather than by individual header;
otherwise, we'd end up overwhelming the GEnie system software by starting
too many 1-3 reply topics.
Again, suggestions are welcome.
#2: Email. My mailer is not bright enough to handle nearly anything.
This will have to be put off for a bit until I get a better one running.
I mean, it would be nice if Internet addresses worked.. :-)
#3: Copyright hassles. Much was made of little in the anthology
copyright. I talked with GEnie about it. Their only concern is that local
BBS's don't mass-download GEnie notes, lifted directly from GEnie, with
their "value added". However, they know enough about USENET to know that
the news software, by its very nature, makes *every* news site form the
same "compilation" of notes in the /usr/spool/news/comp/sys/atari/st
subdirectory -- so there's little point to GEnie claiming any copyright.
I realize there are people out there that distrust GEnie or anything
corporate, so I can probably get a formal statement saying yes, we'll blow
off the copyright for USENET stuff.
What I propose is a TRIAL PERIOD of 30 days for a 2-way link.
If at the end of 30 days it didn't work, I'll say oh well, and go do something
else. This is an experimental project anyway and may not work, and it may
not be possible to really resolve the differences in note paradigm schemes
between USENET and GEnie, on a practical, day to day level. In addition,
it may not be possible for GEnie's editor as a practical matter to do things
like quote from a previous article and so forth.
As usual, I'll filter anyone who asks out of the feed, including
those who've already asked.
The approved method seems to be a vote; would you please send me
your thoughts at dsmall@well.sf.ca.us, or well!dsmall, or however the
note got to you. If even a fair minority is opposed, I'll drop it. I'm
proposing this only because many people were careful to say that their only
real objection to the previous link was its 1-way nature.
There's no rush, by the way. We're busy with 2.5, getting the final
version through beta test (sheesh, 832K is a bitch), writing newsletters,
and the ever-popular packing & shipping tape.
Now, I'm asking *here*, where it'll happen, *before* asking in the
news.* areas, which I'll go to *only* if you local people, who it'll affect,
okay it. THIS IS JUST TO SEE IF I SHOULD PURSUE IT FARTHER. IT DOESN'T MEAN
I'LL TURN IT ON TOMORROW; IT AIN'T EVEN WRITTEN!
I do think there is a substantial advantage in GEnie being able to
access the more international group that USENET has, for both networks.
ST activity in Germany is the envy on the US. Similarly, I get many questions
(34 tonight) via email from users in Europe regarding Spectre, hard disks,
and other things; I'm sure other U.S. companies would like to be able to
communicate with their international users. And finally, while GEnie is looked
down on by some, it's the home of some important stuff -- Jim Allen's
discussion of the 6-chip TOS 1.4 EPROM hassle with SGS 373's, which anyone
with a Mega and that TOS ought to know about; up to date discussions of
PC-Ditto II, which have barely made it here (Bill's working on a software
fix for the problems); the collapse of the large distributor CSS; T-16
accelerator support, and lots of other stuff. It seems to me that it never
hurts to have access to *more* information; comp.sys.atari.st hardly
overwhelms my ability to read it. (A working balance that doesn't drown
USENET in GEnie notes is of course required; at first, I'll hand enforce it,
and anyway the software will need testing. I'll try to avoid any bad postings
by checking them out before allowing UUCICO to send them on their way.)
I realize that this was a very emotional topic a while ago. However,
it was made very clear to me that what people objected to was the 1-way link;
a 2-way link was frequently mentioned as "just fine", much as Portal and
The Well manage their "gateways" (although the Well is just "rn" to me.)
Anyway, what do you think? Would you mind a 30-day trial period
under those conditions above? If, after that, you don't think it belongs,
then it can go into the bit bucket as another one that didn't work.
I need to do some experimenting on how to link the paradigms effectively, but
I won't start until people say it's alright.
Anywho, I've cleaned out my mailbox, and will be checking back
periodically. If anyone really cares, someone else can tally votes, but look,
I'm not going to go to the effort of bringing up a link if it isn't wanted.
Thanks for your time; long note, huh?

p.s. I'd appreciate it if we could go easy on discussing this publicly
until there's been a bit of time for it to propogate and for email to
come in. If there's a negative response, there's no point in discussing it
anyway, is there?

Subject: How to make newsletter available
Message-ID: <15994@well.UUCP>
Okay, those who know more about the 'net and UUCP and FTP than I.
(This should narrow the field by approximately 1%).
We're putting the finishing touches on the next Gadgets
newsletter, and I'd like to make it available online here in some
fashion. It's way too long to just post, unless I broke it into
32K pieces (I believe 32K is the UUCP limit; I've run into it
elsewhere moving files Well <-> Gadgets machine), and look, by far
not everyone here has a Spectre unit nor cares, *and*, it goes
against my grain to more-or-less advertise this way.
Still, I'd like some easy way for net users to be able to
download the newsletter from somewhere.
FTP: I know nothing about FTP. I have no man page for FTP,
no FTP on either my 7300 or the more generic UNIX machine. If someone
is willing to act as an FTP site for the newsletter, and for Doug
Wheeler's much improved GCR disk tester, for downloading, I'd be happy
to send them along, however is needed. Email me here
(dsmall@well.sf.ca.us) if interested.
UUCP: I suppose I could set up my 7300 for UUCP'ing the stuff
across; that'd mean a call for you.
EMAIL: I could probably break the newsletter into <32K segments
and email it upon requests, but this would get old pretty fast, as
you can imagine. Also, I've had bad luck with email bouncing back to me.
I'd really prefer not to do this unless there's no other way.
So, if you would, please educate me on how I can make this available
to you with minimum hassles to us both, and without having to publicly post
it; same goes for Doug's GCR Tester program.
Finally, Doug has also written a truly excellent pageprinter program
for the SLM-804. It outputs your text in form suitable for 8 1/2 x 11 3-ring
binding, double sided, with easy directions to do the double siding. The
result is 4 pages of text reduced on to 1 physical page doublesided, set up
to easily "flip", so facing pages keep continuity. It's currently shareware
on GEnie and is just excellent; if nothing else, it saves a heck of a lot
of paper. Check it out -- it's really nice.
It's no problem for me to post the newsletter to CIS or GEnie; I know
enough to fumble by there (and fumble I do). Here, I don't have the knowledge
to make a good fumble of it even.
If you could email instead of replying here, it'd waste less bandwidth..
-- thanks, Dave / Gadgets by Small
p.s. Would anyone care for a *brief* 2.5 features list as a post? Would that
be an acceptable compromise?

Subject: Page flipping using the VBL interrupt.
Message-ID: <2480@cs-spool.calgary.UUCP>
I posted here almost a week ago asking if anyone could tell me how
to flip between two graphics screens using the VBL interrupt.
Well, I didn't get any replies telling me how to do it, although
many people asked if they could have my results when I was done :-)
(BTW, almost all of my reply mail bounced back with a "host unknown",
or something similar.. If you want to re-write me, by all means ...)
I got it working on my own, and now have a slight degree of gray
scaling for diplaying certain specific pictures (I use it to display
the fractals I generate on a NeXT computer up at the university
on my monochrome monitor at home, which is originally why I wanted
to do the page flipping in the first place. Fratals are more
interesting in "colour").
The only problem is this: The flicker is annoying. It's not really
extreme unless you start working with more than 3 shades, but STILL.
The flicker would probably go away if I was doing the page flipping
on a colour monitor, between two colour images (to generate a
possibility of 512 colours on a medium rez. screen at a time instead
of 16), but that's just an educated guess (I havn't tried it).
I say this because if two corresponding bit mapped "pixels" are
roughly the same colour, as you flip between them there shouldn't
be a big shock to the eye. Rather, if you flip between a white
"pixel" and a black "pixel" at 70 Hz (I think that's the value,
or is it 60?), then they eye CAN perceive the change.
Can anyone think of a way to get rid of the flicker for a monochrome
picture? Maybe using the HBL would have certain advantages.

Message-ID: <15992@well.UUCP>
[The basenote asks questions about SoundMaster with Spectre GCR].
You'll be pleased to hear that version 2.5 (it may be 2.6 shortly)
is just passing final beta test. In it, 60 hz vblank is supported, so both
benchmark programs that use VBL, and more importantly, SOUND, which is
intrinsically tied to VBL, are dead on. No more high pitched sounds; no more
need to convert resources to get the pitch straight. Doug Wheeler did the
coding for this, and many other 2.5 fixes.
With any luck, 2.5 will be out in less than a month. Gotta finish
off the newsletter, get disks duped, start mailing. Free to 2.3K owners.
As for HD Backup, the only name I've heard is DiskFit. Many do not
work because we don't use Apple's SCSI dispatcher... which would be, err,
entertaining.

Subject: Supra, Spectre GCR
Message-ID: <15993@well.UUCP>
[The basenote lists some bizarre problems encountered with a Quantum 80-s
drive, which apparently fooled Spectre into thinking it was 105 mb long.]
Kevin, I'm sorry I missed you via Email; I can't get to the WELL
as often as I'd like, as we're putting the final touches onto 2.5 (very
time intensive).
I think you'll find that what happened is Supra's software left
glop in the trailing ends of the partition sector. GEM ignored it.
However, the Spectre utilities saw the glop, and somehow interpreted it
as reasonable partition data. I really have no idea how it got there;
perhaps a previous user had formatted the drive as a 100 meg unit,
and gotten far enough to stamp out a partition sector? I'm puzzled.
Anyway, I'm glad in a way that the problem is resolved, and you've
found the top possible sector # on your drive. Another way to find this is
just to run PARTCOPY with a long sector count, from the drive to itself,
until it reports a failure.
Naturally, there's always the possibility the Spectre software
screwed up; however, I recall *many* times seeing trash in the "bottom"
of the Supra partition table. I usually go zero it out by hand when I
find it. I'll bet that's what happened to you.
