I happen to have an old AST SixPakPlus card, and a joystick.
My son wants to use that joystick, but AST card needs two chips,
"16-pin IC (No. 558CP) and a 20-pin IC (No. 74LS244)" according
the manual.
I found the last one, but in those electronic stores I tried, 
they could not help me with 558CP, because the manufacturer
was not mentioned. I even phoned to local AST representative,
but they were no better. So: can anyone tell or guess, what 
does 558CP do and who has done it... 
Yes, I know: it had been easier to byu totally new joystic adapter
card...
