Re: PC-to-Apple ][ File Transfer
I plugged the original chip back in (carefully saved all these years -
I'm a "saver"), oriented as the others in the RAM bank (pimple towards
keyboard). When rebooted with the system master in drive 1, the drive
reads for a very short time (too short), Apple ][ appears on the
screen, then everything freezes -- almost as though there were no
autostart ROM chip on the mother board, which there should be, and I
was reading a non-system disk. Reset produces either nothing after the
beep, or a flop into the monitor (which does not respond properly), or
a random character at a random position on the screen. (Granted,
nothing is truly random here.) Reinstalling the language card
corrected everything.
I've been very careful with the game port pins. Originally sticking
the wires in, which was sloppy and laborious, but then using a 16-pin
dip socket into which the wires had been secured ahead of time. The
numbering on the game port socket matches the numbering in the ap2222pc
documentation -- though the pin orientation in the (after-market)
"Using the Apple ][" book I have has the pin banks mirror-imaged, as
though looking at the pins on the controller connector. I followed the
ap2222pc documentation and game port labels.
