SOUPER Memory Mapper 2015-3-30 (SOUPER), 2017-4-10 (SUBPAR), 2017-3-13 (SUBLET) SOUPER is a family of memory mappers for Atari's ProSystem which support up to 512KB of ROM, 32KB of RAM, and optional graphic fetch redirection. An 8-Bit output port is also present for interfacing with an audio coprocessor. All programming files below were created using Altera MAX+plus II 10.2. Support for this mapper with BupChip audio expansion is included in BupSystem.

SOUPER Verilog + POF for an Altera EPM7096LC68. SUBPAR Verilog + POF for an Altera EPM7064LC68, compared to SOUPER... A8, A9, A10, and A11 passthroughs have been removed. audReq_n pin is now a normal output instead of open drain. SUBLET Verilog + POF for an Altera EPM7064LC44, compared to SOUPER... A8, A9, A10, and A11 passthroughs have been removed. audReq_n pin is now a normal output instead of open drain. audCom has been replaced with an external 74HC573. Support for Flash ROM programming has been added through new registers at $808x and the romWrite_n pin. Equates Written for use with DASM - includes documentation and application tips.

ProNES Adapter 2015-5-18 Allows the use of unmodified Nintendo Entertainment System controllers with not only the ProSystem, but also the VCS. ProLine or CX-40 emulation is chosen by pressing [SELECT]. Uses a PIC16C5x to perform the conversion which can be clocked down to 32KHz, allowing the use of super cheap tuning fork oscillators. The supplied gerbers and software below are intended for the small 18-pin flavors of these PICs (x54 and x56). ProLine Mode : [B] = Left Trigger, [A] = Right Trigger, [START] = Both Triggers CX-40 Mode : [B], [A], or [START] = VCS Trigger

ProSMS Adapter 2019-7-7 Allows the use of either Sega Master System or Genesis controllers with the ProSystem and VCS. The switch at its center selects between ProLine and CX-40 emulation like the ProNES. ProLine Mode : [B] = Left Trigger, [C] = Right Trigger CX-40 Mode : [B] or [C] = VCS Trigger

Atari Y/C ProVideo Board 2017-5-23 An S-Video and audio output board which can be mounted directly above the analog section of an NTSC ProSystem. Its circuit is based upon Saundby's with additional buffering. The two potentiometers RV1 and RV2 adjust the Luma and Chroma amplitudes, while the Chroma Delay can be shifted up to three gate propagations.
