Hallo Patryk, > Has anyone of you had some experience .... Not at all, but I put one of my two brain cells in overgear. If the _RFSH line was meant to be connected to GND or +5V only, the designers could have done it inside the IC. IMHO it is meant to tell the IC it can do a refresh without fear that it will be accessed during that moment. If I was using it in a VIC-20 as RAM expansion, then I would connect it to PHI2, knowing that nothing will access it at the moment PH2 = (L). Question out of curiousity: why using a 4168 and going through that much trouble? -- Kind regards / Met vriendelijke groet, Ruud Baltissen www.Baltissen.org Message was sent through the cbm-hackers mailing listReceived on 2013-06-29 07:00:05
