You can set VASYL (that's how we named the chip in question) to take care of the whole raster, including some dynamic actions while the CPU is free once VASYL does the heavy lifting. There's even an already working BASIC extension, which allows programming VASYL directly from BASIC. Meaning you can have pure BASIC programs incorporating nifty visual effects at no cost ;-) > From description I would think you went completely other way of implementation. My solution was to run the cpu ath 2Mhz but slow down with VIC or SID access, I went so far that t have replaceable cpu with 12 Mhz wdc65c02 but CPU clock had to be slow down for io :( but required removal of ram and cpu and costed too much :) Overall not very practical and not cheap. So my question would be what does it take to implement VASYL on stock C64, does it works on C128 and how much does it cost :) Regards, ZoranReceived on 2020-05-29 23:28:38
