JOY81 - Programmable Joystick Interface for ZX81
Posted: Tue Apr 30, 2013 9:01 pm
Hi there,
I developed a Programmable Joystick Controller (the JOY81) and I'm thinking of producing a small amount of it and would like to know if anyone here would be interested in purchasing a unit.
The controller is compatible with one or two buttons Atari joysticks and programming it is as simple as set the BASIC commands
LET J$="QAOPXL"
RAND USR 16514
or even better, if you have a ZXpand interface. In this case, the programming is done automatically by ZXpand Commander from configuration file JOYCFG.TXT stored in the root directory. Set an entry for your game in the JOYCFG.TXT once and whenever you load it by Commander, the joystick will be magically configured. Play any game with the joystick, do not have to worry about changing the game code for it anymore.
The controller was developed in format of slot card for use with the ZeXtender, an extender board similar to the Maplin Extender. See the prototypes:
Estimated price to produce an amount of 30 units of ZeXtender + JOY81 is 30 GPB and shipping from Brazil to EU is about 12 GPB.
So what do you think? Do you have interest in these things?
Thanks,
Kelly Murta
