> Meaning that every C64 was like very other C64, so you knew what you had to work with on the hardware side. Well, other than: 1) PAL vs NTSC systems. True compatibility breaker. 2) Two different versions of SID sound chips (and every SID being more or less unique) 3) Different VIC-II versions (or at least some chips where VSP (variable screen positioning, a fast method for horizontal scrolling) works and some where it doesn't)). |
