ITXPlus

ITXPlus is a ITX sized Macintosh Plus clone that can be built with no original parts 

 ITXPlus is mostly a squished down SMT clone of the original board with a few differences:

A full 4MB of RAM is soldered to the board (8x 1Mx4 ICs)

Onboard VGA, PS2 for keyboard / mouse and a internal 50pin SCSI connector

ATX power connector

IWM removed (so no floppy support by default) and replaced with a pldSCHWIM

Sony Sound chip has been replaced with DosFox's replacement design.

ITXPlus was only made possible Thanks to the work of others, it uses:

DosFox's Sony Sound replacement design (https://github.com/DosFox1/Sony-SND-THT-Replacement)

pldSCHWIM - my implimentation of DosFox's SCHWIM in a single 16V8 PLD (Original design: https://github.com/DosFox1/Shim-IWM) (My design: https://github.com/max234252/pldSCHWIM)
