They are good for all 'long boards' (except 250466). See http://personalpages.tds.net/~rcarlsen/ ... c64-ic.txt

Code: Select all

U9 THRU U12 & U21 THRU U24 8 RAM CHIPS (generic 4164 DRAM) note: only 2 4464 RAM chips in later C64C boards Blank screen, no border. Shorted chips will get warmer than the other RAM chips. Partial failure: will sometimes produce "garbage" screen, abnormal number of bytes free or "out of memory" error on startup screen. Top Gerrit4 Posts: 42 Joined: Mon Feb 27, 2017 7:24 pm Age: 57
