26-09-92 The following will explain to you how to use the extra joysticks
and how to build them yourselves. You might be able to find some people
selling these things complete.
The 2 extra joysticks that plug into the centronics printer port, also
known as a paralell joystic interface. N.B. this adaptor may also be used
with games such as Leatherneck, Gauntlet 2, and Projectyle to access those
extra players. The file PAR_JOY.ASC contains the STOS basic sourcecode on
how to use this adaptor in your own games. As it is in ASCII, it can easilly
be adapted for other basics, or even machuine code. This method of reading
the joysticks has, for some strange reason, the habit of screwing up both
diskdrives, so make sure all your data is loaded before you use it, and also
when testing, make sure you have saved your program first. The diskdrives
are restored to normal when you reboot the computer.
Parts required : 1 x 25-pin male D type plug
2 x 9-pin male D type plug
Enough wire for 12 connections.
Optionally, you can get covers for the adaptor.
The pin numbers are sometimes written on the back, if they are not there,
then the numbers are if you are looking at the inside of the plug. Connect
the wires up in the way shown. When the wires cross (÷) they do not connect.

Have you ever stared at the left side of your STE, and wondered what the
hell you are meant to do with those two unusuall ports at the side? Well,
you can stop staying up all night and wonder, and instead, build this
adaptor to allow you to plug normal joysticks in them and play any game
that uses the STE's extra ports for joysticks. I have included a STOS basic
listing (STE_JOY.ASC) which can be examined, used in your own programs, and
it can easily be converted to machine code. If you have the STE extension
for STOS by Asa Burrows, then it has some commands for reading the STE's
extra joysticks, making STE_JOY.ASC unnescersary.
N.B. this shows how to make one adaptor for two joysticks. Do exactly the
same for the second one. Also, the listing does not affect the diskdrives
like the previous one did.
Parts required : 1 x 15 pin D plug
2 x 9 pin D plug
Enough wire for 14 connections.
N.B. the pin numbers are printed on the plugs in most cases.
