Clone IOU / MMU Chip

["Bryan Parkoff" <nospam@nospam.com>]

Hello,

    Would you like to clone IOU / MMU chips?  You have a better 
understanding information from "Understanding the Apple //e" manual.  You 
have the information about the timing and logic circuit already.  You will 
need Logic Anaylzer to capture pulse stream from some or all IOU / MMU's 
pins.  Fill the gaps using Jim Sather's schematic and/or yours.  Build new 
custom chip.  Use Logic Anaylzer to capture pulse stream from custom chip's 
pins.  Compare pulse stream data from both IOU / MMU chip and custom chip. 
If they are identical, but schematic is different on both chips, you are 
ready to install custom chip on the MMU / IOU socket of Apple //e's 
motherboard.
    Do you expect it to work?
