Hallo Ruud, I also read this article and I remember it very well. It is a very straightforward and, if you like, brute-force approach to get the HIRAM status to the external cartridge. I liked that idea :-) In the times when Commodore was still alive, spare parts were not that expensive. I remember buying CIA chips always in the range from DM 25 to DM 40, so I think the CPU will be in the same range, probably even cheaper. Just study some old ads of Rat&Tat in 64'er and RUN. Another thing that I always wanted to try, but never got around to do it, is that they say that the cartridge works without the 6510 if a C128 is being used! This would mean that on a C128 somehow the signals on the expansion port are different according to the state of the internal HIRAM signal. I always wondered what that difference was. Anyone an idea?
