Ah nice, i did not know this exists.
Intresting.
Jan Audio:
This thing has 19 adress inputs :

Anyone know how these work ?
thanks

These are the simplest things ever. Tie the chip and output enables low. Drive an address. The word stored in that address appears on the data bus.

So i can use all 19 pins from 0 to -1 ?
Then i can dump it into SD card, and done.

Rig up something that can drive the addresses in sequence from 0x00000 to 0x7FFFF and capture each word. If you have an FPGA or microcontroller board lying around this is trivial. Design a serial port that transmits the address and the corresponding data back to your computer where it can be stored in a file or whatever.
