Adding a keyboard (and other upgrades) to the Bally Professional Arcade in Gunstar's Blogs A blog by Gunstar in General Posted March 22, 2022 On the Astrocade discussion group you asked for feedback here. I don't see any corrections that need to be made, but here are some clarifications: 1) The 64K RAM board in the 1980s could bank-switch RAM in the 1980s. It could even bank-switch out the internal 8K ROM. The manual is here: https://ballyalley.com/documentation/misc_hardware_docs/full_size/64k_ram_board.pdf 2) The Lil' White RAM is called that because it was designed by Ken Lill and Mike White. Nice pictures and nice work! Adam 1
