This is a little pamphlet that tells you how to use the NASTY connection
for transferring files and other fun stuff.



0. CAVEATS

OK. This is not the product of any commercial enterprise, that actually
tries to make money with this, so I the lowly hacker just stopped when
it was good enough for me. If I find the time, these bugs will be fixed
sometime, but for now I will just tell you what they are so that you can
circumvent them.

A) The connection may be succeptible to outside interference. I have a
   refrigerator that creates an interrupt everytime it starts cooling.
   Be sure that your connection is shielded as much as possible, and
   your co-inhabitants aren't blowdrying in the same room. (har har)

B) The server software on the ST is designed to be multitasking. But
   it doesn't. Don't do file accesses from the ST, while using the
   connection. If you don't use the connection, you can use the ST
   as usual. On TOS 1.2 it multitasks a bit, but then again it hangs
   on occasion.

C) Just very occasionally the connection might hang. Press RESET on
   the 8Bit to try to resync the two computers. If this fails press
   RESET on the ST and reload NASTY.PRG. Then press RESET on the 8Bit.
   If that fails power down both and retry.

D) Nasty installs itself after DOS at MEMLO, this is inconvenient when
   using anything else than SpartaDOS, since DUP.SYS overwrites
   that space.

E) Since most DOSes make some stupid assumptions about what handlers
   other than D: should behave like, using N: is often not as con-
   venient as using D:. The best DOS so far seems to be SpartaDOS 2.3

F) SpartaDOS X cartridge uses a custom handler scheme, which I haven't
   been able to crack (yet). You can still use NASTY from within other
   programs, but the X cart. command line interpreter, won't recognize
   N:.

G) Many programs make some false assumptions about filenames (all
   beginning with D: f.i.), which need to be patched if they are to
   work with NASTY. Some programs which load data files from disk
   also need to be patched.

H) At start up NASTY on the ST sets its default path to G:\NASTY\.
   Patch if you want something else, or do a CWD N:A:\ first if
   you don't have a partition G: on the ST.
   
I) May/Will probably not work on the TT.



1. BASIC USAGE

Connect everything. The joystick connectors into PORT A i.e.
the first two joystick ports (right order!!), SIO cable 1 into the 8Bit
computer, SIO cable 2 into your disc drive, the 25 pin plug into your ST.

Start up the ST and load NASTY.PRG there. NASTY.PRG should be the last
program in your AUTO folder, if you elect to start it there.

Start up the 8Bit with SpartaDOS 2.3 and load NASTY.COM

That's it. Now you can use N: like any other CIO device.

In GEMDOS the delimiter for subdirectories is '\' in SpartaDOS
it is '>' and in UNIX it is '/'. You can use any of these in NASTY.
'<' will be expanded to approximately the same as .. (meaning one
up in the hierarchy.



2. SUPPORTED XIO COMMANDS

   CWD  ERASE  CREDIR  BLOAD  NOTE   PROTECT
   ?DIR RENAME DELDIR  BSAVE  POINT  UNPROTECT


RENAME    - 32/$20   e.g. XIO 32,#1,0,0,"N:FOOBLE.BAS LEOPOLD.BAS"
ERASE     - 33/$21   e.g. XIO 33,#1,0,0,"N:C:/BILBO/FROBOZZ.DAT"
PROTECT   - 35/$23   e.g. XIO 35,#1,0,0,"N:C:/METAL/METALLICA"
UNPROTECT - 36/$24   e.g. XIO 36,#1,0,0,"N:C:/METAL/VAN_HALEN"
POINT     - 37/$25
NOTE      - 38/$26
BLOAD     - 40/$28
BSAVE     - 41/$29
CREDIR    - 42/$2A   e.g. XIO 42,#1,0,0,"N:C:/METAL/THRASH"
DELDIR    - 43/$2B   e.g. XIO 43,#1,0,0,"N:C:/METAL/THRASH"
CWD       - 44/$2C   e.g. XIO 44,#1,0,0,"N:C:/METAL"
?DIR      - 48/$30

Look up your SpartaDOS manual for more information. NASTY works exactly
like SpartaDOS in this respect.



3. EXAMPLES

Assuming you have a disk in drive A: with some BASIC programs on it
in folder BASIC.8BIT called A.BAS and D.BAS you can load them with

Ready
LOAD "N:A:/BASIC.8BIT\A.BAS"

or
Ready
XIO 44,#1,0,0,"N:A:>BASIC.8BIT": REM change default directory

Ready
LOAD "N:D.BAS"


Under SpartaDOS 2.3:

D1:N:

N:COPY D1:*.* N:F:/TMP

copies all files from the root of D1: into F:\TMP of the ST. This
doesn't work backwards unfortunately, because SpartaDOS can't imagine
that N: might be a file system as well.

N:ERASE FOO

N:PROTECT FUBAR

N:CREDIR  TMP

N:CWD TMP

N:?DIR
G:\TMP

N:
et.c.
