It's been some time since I tried those (and it was not in the '466 either) but I didn't notice anything striking. The R1 with its luma levels makes a noticeable difference but the later ones? http://www.breadbox64.com/blog/the-lumafix64-mod/ "On the positive side, images produced by the MOS 6569R5 graphics chip left the rest of the test chips in the dust! This chip showed far less vertical stripes, less smearing and checkered patterns. " Also the DRAM timing was fixed for the C128 and then the R5 VIC2 came out after that, earlier revisions required production to add random capacitors until it appeared to work good enough (until it got warm). https://youtu.be/cwr8tTFGZtI?t=1526 I can't find the video when Bil Herd said that everyone at commodore was stealing the VIC2 out of his prototype (which may have been the prototype C16 or C128 which both used a VIC2 tower) & he left a tube of them on his desk. I have a vague feeling these were R5's. Message was sent through the cbm-hackers mailing listReceived on 2017-02-19 20:03:09
