DIP Implementation

There are three base projects for all DIP chips in the ARP, including (but not limited to) Skinny Agnus, Denise and Paula. These come in three footprints: 48-pin, 40-pin and 28-pin and all are based on the iCE40-HX8 FPGA. The DIP-48 and DIP-40 boards both have both SPI Flash as well as SPI pseudo-SRAM enabling various memory expansion options. The DIP-28 presently do not as there's no room left.

The DIP-48 is presently our most developed board and may lead the other two in terms of features. These should all be considered a WIP, however, and there may be errors in the schematics or design we've not yet found.

All of these chips are "flip chip" so that the top-side is simply a bare PCB to look as much like regular chips as possible.
