Is anyone else upset at Tramiel submerging the best 6502-based micro on
the market under a so-so 68000-based machine? It's nice to have all that
extra memory, sure, but not if it makes the machine more expensive than
the (ick) C=64? Is there any real advantage to the extra RAM in the 130
over the 800XL?

WOW...this sounds like _ALLOT_ of work. Before I started writing programs,
I would try to convince my friend to buy a $35-$40 XM-301 modem for his
Atari. You could then download binarys/text to your Mac and transfer them
over to him.
Anyway, to answer your question:
(this stuff comes from _De_Re_Atari_)
Ataris write fixed-length blocks at 600 baud (to tape).
Two frequencies are used:
5327 hz. for a mark (or 1) and
3995 hz. for a space (or 0).
A byte is defined by:
1 start bit (space)
0-7 data bits (marks and spaces)
1 stop bit (mark)
Records should be written to the tape in the form of:
01010101 1st marker
01010101 2nd marker (markers are for speed measurement)
control byte
128 data bytes
checksum
The control byte is defined as:
$FC indicates the record is a full 128 byte data record.
$FA indicates the record is a partial record (less than 128 bytes).
$FE indicates the record is an EOF.
NEED I SAY MORE?

Thanks a lot to all who responded to my question. I'm all set,
having received lots of detailed data from at least two sources.
I'll try to play with it, realizing very well that it would
be much easier to simply get a disk drive for my friend (as for
the option of sending stuff via modem: if you had anything to
do at all with the Polish telephone system, you wouldn't say a
single bad word about MCI & the like - so that's out. I mentioned
in my first posting that the source of all problems is my friend's
geographic location.)
Thanks again -
Eric

The version of SHRINK.COM posted by Paul Kopp, like the previous one I got
from someone else, did not work. I am beginning to wonder if it is I who
need a SHRINK. The programs both downloaded OK, uudecoded OK, and... failed
to load. The error message from DOS in both cases was 136, "Attempt to Read
Past End Of File", which suggests that the original file has a problem with
its load vectors.
Has anyone else experienced this problem with the version of SHRINK.COM
that was posted? Has anyone else successfully uudecoded and loaded it?
Aside from all that, I STILL don't have a working SHRINK program or
equivalent, so I am unable to post Turbo BASIC / FROST BASIC for those
800 owners who are eagerly awaiting it. Since we are THIS close to a way
of posting it, however, I would like to urge someone to find a version of
SHRINK or an equivalent program, test it, and e-mail it to me or post it.
Better yet, uuencode it, uudecode it using my UUDECODE.BAS, and test the
decoded version. If THAT works, then send me the uuencoded version and
there is a fighting chance it will work at my end. If that fails, maybe
we should ftp it?
Heeeelllllpppp!

There seems to be (based on the 16 bit traffic) plenty of reasons to be less
than satisfied with some aspects of ATARI, but the cost of the 65XE compared
to the C64 and the 130XE compared to the C128 is not one of them.
When my old 800 began to bite the dust (~$900) I definitely went for the
extra memory in the 130XE (~$125!). Ramdisks are very nice on the ATARI.
You can use the extra memory for program/data space, but my guess would be
that most use of the memory is for ramdisk.
