CALL -1370. Re-boots disk system.
|
|
|
|
Want to omit the pause when you issue
|
|
the CATALOG command and you have
|
|
more than a screenful of programs?
|
|
It's easy! Enter the monitor and
|
|
type... AE34:60 ...(DOS 3.3)
|
|
|
|
PEEK(-18070) If 150 is returned then
|
|
you are using DOS 3.3. This PEEK
|
|
works for both Applesoft & Integer.
|
|
|
|
Here's a 16/13 sector hardware mod:
|
|
(Allows you to switch between DOS
|
|
3.2 & 3.3 without Basics Disk by
|
|
simply flipping a switch).
|
|
Remove P5A chip from P5 socket.
|
|
Get the original P5 (DOS 3.2) chip.
|
|
Bend out pin 20 on both chips and
|
|
place the P5 chip on top of the P5A
|
|
chip (piggyback). Solder pins 1-19
|
|
of P5 chip to pins 1-19 of P5A chip.
|
|
Insert one end of a wire into pin
|
|
20 of the P5 socket and solder the
|
|
other end to the common (center)
|
|
connector of a SPDT switch. Insert
|
|
the 2 piggyback chips into the
|
|
P5 socket (pins 20 of both chips
|
|
should not be inserted into the
|
|
socket or connected to anything at
|
|
this time). Solder pin 20 of P5 chip
|
|
to one of the 2 free connectors on
|
|
the SPDT switch. Solder pin 20 of
|
|
P5A to other switch connector. Be
|
|
sure there are no shorts, that you
|
|
followed directions before turning
|
|
on power. Flipping switch in one
|
|
direction or the other selects be-
|
|
tween either DOS when booting.
|
|
|
|
NOTE: This will definitely VOID your
|
|
warranty. If you make this mod
|
|
you do so at YOUR OWN RISK. Had to
|
|
say that so I don't get sued (but
|
|
the mod WORKS).
|
|
|
|
|
|
For Language/Memory Card users: If you
|
|
are tired of DOS 3.3 dumping whatever
|
|
language is on your card every time you
|
|
re-boot with a PR#6, here's the fix:
|
|
Using Dan's Disk Utility or some
|
|
other similar program, read track 0,
|
|
sector $09, byte $CC (should be $81)
|
|
and change it to $10. Now when you
|
|
do a PR#6 whatever is in the
|
|
language card will still be there.
|
|
|
|
Here's 4 good POKES I'm sure you'll
|
|
find a use for. They will turn your
|
|
disk drive(s) on & off without
|
|
reading or writing. You can use
|
|
these to run the dri
