Apple's ASIC's
Apple's Application Specific Integrated Circuits, Programmable Array Logic's and Read Only Memories
The original Apple II did not contain any Application Specific Integrated Circuits (or ASICs) as part of its design, making it a fairly straightforward task to not only copy but also to bring into the FPGA's domain. However, other Apple models did use ASIC's, as well as ROM's and PROM's for logic conditions. Capturing these correctly is paramount in ensuring the design is faithfully implemented into the FPGA design space. To aid the process of capturing these devices, each of the ASIC devices used in the various Apple designs are identified as follows, listed according to model with data and device location for each of the respective logic boards.

The keyboard ROMs for the IIe are not specific to enhanced or non-enhanced (the enhancement kit only replaced the CD/EF firmware,the Video CG ROM and the CPU) but there are at least two differentkeyboard layouts that only differ in the numeric keypad part of the lookup table. Either will work in a beige IIe but the Platinum IIe needs the correct one to match the on-board numeric keypad.
