Home Page Forums MAME MAME Triumph-Adler alphatronic P3 (+ P1, P2 and P4)

helwie44's spent countless hours on mapping the keyboard. I'm especially surprised that he managed to find an equivalent for the P3's "SM" (Schreibmaschine) key. It's mapped to F11 and controls the shift mode of the keyboard.
I got a P30 today, a P3 with a graphics extension and a 8088 coprocessor card with its dedicated 128K of RAM. The 8088 card ROM and the 8085 MOS were a direct match of what we had from another German user, I added the correct ROM label for the 8088 ROM, verified the char ROM and dumped the keyboard controller.



This picture was taken before I moved the rightmost card one slot left, this got it booting. The rightmost slot carries additional signals for I/O cards.

The P30 is using a different floppy controller card than the P3's built around a WD2797



The three extra cards are tied together with ribbon cable:



They're the 8088 CPU card, 128K RAM card and a 32K Graphics extension that provides 640x288 pixels in 8 colours.





The heatsink hides a memory controller



This is the graphics extension:



The files are already on the FTP and you can find them here.

Unfortunately the current state of emulation doesn't like the addition of the new keyboard controller - it prints "w#" and dies



If you boot a disk on the 8085 side, it again dies after printing "w" you need a hard reset to get it out of that state.
