Anyone of you have some documentation about the Disk/File system format for Motorola M68000 EXORMACS?
I found this pdf: https://bitsavers.org/pdf/motorola/versados/M68KVSF_D7_VERSAdosSysFacilities_Oct85.pdf
it has an example first sector on page 346 (pdf) / page number 336 but not much explanation of, or I couldn't find it because it's not searchable
Anyone want to help figure out the Lisa A-trap dispatcher? I put a disassembly in a gist: https://gist.github.com/eschaton/2c9cdcddccd3dde177005872ddd6e946

This new 68000 bears an original-looking Motorola logo.
Does NXP (or whoever licensed the #m68k IP) still labels them like this, or did they send me a vintage MC68000P8 part?
I soldered a new 64-pin socket on my #Amiga 500+ board under restoration and plugged in the #m68k.
It's still too early to tell if it works, but I've seen it toggle the R/W signal a few times at power on.
To make further progress, I need to find a Gary, the gate array which controls chip selects and various bus signals.
I ordered a single #m68k from the YUXINYUAN store on AliExpress for ¥150 + ¥300 for international shipping from Shenzhen ($2.87 total).
It arrived here in Tokyo in just 4 days. Yes, wow.
