[net.micro.atari8] RAMDisks and SpartaDOS

hyc@UMIX.CC.UMICH.EDU (Howard Chu) (09/16/86)

Hello,
	I got most of my other problems worked out. I'm now happily tele-
computing at 1200 baud on a UltraSpeed 1050 drive, using SpartaDOS 3.2c.
The problem I reported before with the modem was really the fault of using
the wrong R: handler. Getting the right one was trivial.
	My question now is - how many of you have installed the Newell 256K
RAM upgrade to your 800XLs, and how many of *you* use SpartaDOS? Do you have
a RAMDisk driver that supports the Newell upgrade? The RD programs that come
with SpartaDOS only support the RAMBO XL upgrade and one by Claus BuchHolz
which was printed up in Byte magazine. Naturally ICD, the people who
created/publish SpartaDOS, and who manufacture/distribute RAMBO, don't seem
too enthusiastic about supporting a competing upgrade. Anyone gotten around
this difficulty?
	Thanks in advance for any suggestions...

Both Newell and I support the Rambo XL with our software.  MYDOS, which
comes with the 256KXL, is flexible enough to support it, the 256KXL, and
AXLON compatible ram upgrades.  The same is true of my OmniWriter.
Since the differences between these upgrades are very small for ramdisk
applications, there is no reason not to support them all except if you
need a marketing gimmick to help sell an inferior product.

Just this week Gord Spielmann of Oshawa, Ontario wrote to me with a
patch that is supposed to do the trick. He writes:

For the SpartaDos RD.COM file, the changes are on sector 148.  The
original file contains the following byte sequence:

60 64 68 6C 20 24 28 2C ...

For the 256KXL this has been changed to:

60 64 68 6C 40 44 48 4C 00 04 08 0C 20 24 28 2C ...


I don't know if this patch works since I have not tried it.  Let me
know if anybody has a problem with it.

By the way, OmniCom, my VT100/Kermit/XMODEM package, is almost ready for
distribution to the net.  I will be putting it on a <DUMMY> directory on
our host that anyone can access via FTP without a password.  The only
requirement is OMNIVIEW for the 80 column output.  Send me your mailing
address is you need more info on OMNIVIEW.  I will let everyone know
when OmniCom is ready to be fetched.

Thanks very much for the info, the patch works. Fixing the files was
a breeze using OmniMon! I don't need to use it every day, but when I
need it, I'm glad it's there...

AMEN to your comments on OmniMon.  It sure makes life easier when it's code
patching (or disk patching) time!
