Hallo allemaal, FYI: I decided to start with a version without any DMA. The main purpose of this design is to have a solid base and then we can add DMA. Rereading the "Speed" part at the beginning I realised that I have been so foccused on the C64 that I completely forgot that the C128 has much more free memory ranges due to the bankswitching. In this case I am particulary interested in those ranges which do run at 2 MHz. The range used by the free socket (U36 ?) comes in mind. But I must admit that I'm not familiar with the C128-mode of the C128, particular the behaviour of some lines of the expansion slot (EXROM and GAME can become outputs IIRC?). So I would like to ask: - which ranges are free at 2 MHz? - (how) are they accessible using a cartridge?
