Ive been attempting to create a pinout of that 68K. I’m pretty sure what I’ve got so far is accurate although I make no promises as it does get a bit confusing sometimes. If you can shed any light on the pinout of this chip I would be grateful.

—CUSTOM 68K—
pin 7 = A1
pin 8 = A2
pin 9 = A3
pin 10 = A4
pin 11 = A5
pin 12 = A6
pin 13 = A7
pin 14 = A8
pin 15 = A9
pin 16 = A10
pin 17 = A11
pin 18 = A12
pin 19 = A13
pin 20 = A14
pin 21 = A15
pin 22 = A16
pin 23 = A17
pin 24 = A18
pin 25 = A19
pin 26 = A20
pin 28 = A21

pin 27 = VCC
pin 54 = VCC
pin 55 = VCC
pin 56 = VCC
pin 64 = VCC

pin 31 = GND
pin 58 = GND

pin 32 = D7
pin 33 = D6
pin 34 = D5
pin 35 = D4
pin 36 = D3
pin 37 = D2
pin 38 = D1
pin 39 = D0
pin 40 = D15
pin 41 = D14
pin 42 = D13
pin 43 = D12
pin 44 = D11
pin 45 = D10
pin 46 = D9
pin 47 = D8

pin 48 = AS
pin 49 = UDS
pin 50 = LDS
pin 51 = R/W
pin 52 = DTACK

pin 57 = CLK

This post will be updated with any new information if/when I get it.
