I've made a comparison of the opcodes of the 8048 vs. NS405 (based on the names in mcs48.cpp and the NS405 datasheet). You can find the table here. I've marked where opcodes are shifted to different positions, have names similar enough to be the same and have identified a possi...

Working on C64 support for samdisk... The same GCR encoding and similar zoned format was used later on Victor 9000. Also found and hopefully fixed a bug in HxC's GCR encoder - this should let me write d64 images via SCP card. Code [A Dolphin's Rune [Index].scp] 35 Cyls Head ...
