========= OS =========
Chips: unknown 28-pin EPROMs (dumped assuming AMD AM27512)


========= SOUND ROM's =========

As a bonus, desoldered the sound ROM's exclusive to the ProtoLogic expansion (not the standard Proteus 1 samples mainly because those are still legally available anyway), and converted into a 16-bit little-endian WAV sample as well.

Chips: 8 512kB Mask ROMs (AKN62314BP series, see included datasheet)
Pinout: 27C040 / 27C4001 compatible (dumped with AM27C040 settings)
