Thanks to the Enterpress publication, now I know that
Támas Kiss, the creator of the very professional Hungarian keyboard membrane(I own two of them), is also selling moulded copies of the joystick cap.
I have just bought four from him...
But he is also interested on reproducing other parts of the computer, the expansion connector cap, the heat-sink cover, and most interesting.....cartridge halves.
But he needs perfect originals to do it, he lacks the expansion cap and his cartridge is crackled.
Surely some of you can lend him a nearly new cartridge and connector cap to make the moulds.
He writes me this:
"Unfortunately the parts in question are missing from my EP, so i don't have a sample to reproduce them. I have a cartridge, but there are cracks on it, so it is not good for replication.
I will try to get a good cartridge and expansion cap next week and make some tests for the "mass" production. I will contact you soon."
Please, hurry, contact him.
