Cartidge ESE-SCC SRAM 4MB. builded based in original design made by K.Tsujikawa, features:
- Pure SRAM 55 ns., (not Pseudo-RAM designed in original circuit)
- Logic build made with HC types
- Works with MSX enhanced Turbo machines (8Mhz tested!, maybe can reach more speed)
- To avoid problems in sound SCC with Turbo speeds, a 3.58Mhz oscilator is installed inside cartidge at CLK signal= Perfect sound SCC with Turbo Speeds and no need to use the cartidge with 3.58Mhz slowdown slots in Turbo modified machines.
- Battery Switch ON-OFF: 1F Goldcap inside, long capacity capacitor to mantain for a long time games or anothers inside Sram meanwhile Battery Switch will be set in ON position
- Audio Out by Jack Pseudo-stereo, in Switch position OFF we can ear only SCC Sound, with ON position we can ear PSG+SCC sound towards jack stereo out.
- To get PSG only sound towards jack stereo out, according msx machines, PSG should be redirect inside MSX machine to allow goes to cartidge slot like IN and no OUT(msx machines default, ask about this i have a basic diagram to follow for redirection)
- Dedicated sticker.
