Bought MTX512, but it turned out to be MTX500 in MTX512 case! Came with manual including PALASM source for the MTX PAL chips, which helped me improve memory map logic in MEMU.

Uploaded PALASM. Added description of memory decoding. Added suggested MTX500 to MTX512 upgrade path.

Got scans of the source code of the SDX ROM. Working to reconstruct useable source files.

SDX ROM disassembled, source reconstructed, and alternative version prepared for use in REMEMOTECH, which works fine.
