Hallo Gábor, > I've tried to use SRAM module, which is much easy, since you > haven't need refresh :) 1) The largest SRAM I know of is 512 KB. And for 16 MB you still need 32 of them.... 2) I have loads of DRAM modules laying around and only one 512 KB SRAM. > Is it a very crazy idea, or can it be done at least? In fact, I already built one but it had problems . But that one was and a new one will be a lot of work ie. will cost a lot of time and _that_ is where the problem lays. But I dreamed up a very simple circuit (compared to my previous ones) that I want to build before November the 24th (HCC dagen in Jaarbeurs Utrecht). This design can only run at the original clockspeed but the idea is that, if it works, we have a solid base far a more faster design. I'll keep you informed about this one.  The design was an interface between the 6510 socket and an existing 65816 card made by Elektuur/Elektor. The problem was that the C64 froose a few seconds after start-up. Inserting a FC3 kept it running but the graphics looked quite weird. Some friends suspected one or more bad points of soldering. I also suspected the distance between the 65816 and the socket (about 20 cm). -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org =====DISCLAIMER================================================================= De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
