Atari XE 1MB XE SuperCart
Belcher Jul 18,2021
XE 1M Cart Instructions (Rev A)by Bryan EdewaardThis board is designed to fit into the new Mq/Sikor shell and provide up to 1MB of ROM space via bank-switching. It can also be configured for a non bank-switched 16K ROM.The switching scheme is based on the XE cartridges produced by Atari. Any access within 8000-9FFF will read from the selected 8K bank, and any access within A000-BFFF will read from a fixed bank (the topmost 8K in the ROM). A write to the D5 page (D500-D5FF) sets the current bank....

Atari Jaguar to Genesis 2 AV cable adapter
Solder Jun 02,2021
IntroductionI wanted to use my Atari Jaguar on my television set, but it only came with an RF cable.
