Hi Gerrit, I have two 6569R4s, 6569R4 3585 and 6569R4 4285. I will check this, but I think every 6569R4 and 6569R5 I have (that still works) has the colour $F light grey 2 pixel dots. Recently I went to the trouble of documenting all my C64 board revisions, SID types and VIC-II types. From the info I obtained, it looks like MOS only made 6569R4s briefly in 1985, and then went back to making 6569R3s for a bit before switching to 6569R5s. There is a 6569R3 0586 that I think was a part fitted by a repair outfit, because it was in a machine with 1983 parts except for that and a 906114-01 3086 PLA. I would be interested to see if there are other chips out there that are consistent with, or contradict, this hypothesis. Here are the VIC-IIs in date code order, NTSC then PAL. I have moved a few chips around a few machines so they are not necessarily in the machine they originally came in. Also, some of my machines have obvious signs of being repaired and having had chips replaced before I obtained them. I use the terminology 'C64' for a breadbox machine, either tall case or short case. '64C' for the 250466 12V 65xx-containing machines and 'C64C' for 250469 9V 85xx machines. 6567R56A 0383 Box 6567R8 3283 C64 NTSC P5767904 6567R8 3384 Box 6567R8 3584 Box 6567R8 0786 C64 NTSC P2495705 8562R4 4388 C64C NTSC HB 1020855 8562R4 4589 C64C NTSC HB 1078700 6569R1 3482 Box (originally in WG B 0693) 6569R1 4882 C64 WG B 11759 6569R1 0983 C64 UKB 112421 6569R1 1183 C64 WG C 33994 6569R1 1983 C64 UKB 142386 6569R1 2083 Box6569R1 2083 C64 UKB 102186 6569R1 2183 C64 UKB 300649 6569R1 2283 Box6569R1 2283 C64 UKB 161064 6569R1 2283 C64 SECAM WG C 35678 6569R1 2283 C64 WG B 14573 6569R1 2283 C64 WG B 0693 6569R1 2683 C64 UKB 2163411 6569R1 2783 C64 WG B 12356 6569R3 ceramic 3183 C64 UKB 331096 6569R3 ceramic 3383 C64 UKB 213407 6569R3 ceramic 3383 C64 UKB 1652216 6569R3 4083 Box6569R3 4383 Box6569R3 2184 C64 UKB 1941010 6569R3 2384 C64 UKB 968153 6569R3 3684 C64 UKB 1413593 6569R3 3784 C64 UKB 1906995 6569R3 4284 C64 UKB 1912138 6569R3 0785 C64 UKB 2313234 6569R3 1985 C64 in Micro Accessories case 6569R4 3585 C64 UKB 496433 6569R4 4285 C64 UKB 2394132 6569R3 0586 C64 UKB 275453 6569R5 1886 C64 UKB 1656468 6569R5 1886 C64 UKB 2354218 6569R5 2186 C64 UKB 485294 6569R5 3786 64C DA5 012957 B1 6569R5 4286 64C DA5 018855 B1 8565R2 1087 C64 Aldi WG A 437658 8565R2 1488 C64G DA4 137935 8565R2 2088 C64G DA4 235599 8565R2 2888 C64C HB5 311175 E 8565R2 4288 C64C HB5 347927 E 8565R2 4288 C64C HB5 351691 E 8565R2 2989 C64C HB5 228528 E 8565R2 3789 C64G DA4 334645 8565R2 3789 C64C Ser No 548743 8565R2 4589 C64C HB5 436306 E 8565R2 0590 C64C Ser No 646870 8565R2 1190 C64G DA4 344288 8565R2 1190 C64C HB5 465243 E 8565R2 2990 C64C HB5 523083 E 8565R2 3090 C64GS DA4 002213 E 8565R2 3090 C64GS DA5 016341 E 8565R2 4490 C64C HB5 085372 E 8565R2 4890 C64C HB5 109771 E 8565R2 2991 C64C DA4 - B1 8565R2 3091 C64C HB5 131759 E 8565R2 3691 C64C HB5 155187 E -------------------------------------------------- From: "Gerrit Heitsch" <gerrit@laosinh.s.bawue.de> Sent: Saturday, November 19, 2011 5:43 PM To: <cbm-hackers@musoftware.de> Subject: Re: Blurry picture > On 11/19/2011 03:37 PM, Richard Atkinson wrote: >> Pasi, I'd love to know what the chip numbers and date codes are on these >> VIC-Is that exhibit the effect.
