Thanks to > achim@boinx.com - who sent them to jpf3@po.cwru.edu. The schematic quality is good enough, they are readable. For an Apple I replica there are a few parts that are difficult to obtain: The 4096 4k RAMs, the 2513 char generator, the 2519 (is this a latch???) and the 2504 ccd delay lines. However, an Apple I clone (with slightly modified circuitry) could easily be build. The 4096 could be substituted with 4116, instead of the 2513 a 2716 can be used. Next month I will try to build one as a wire-wrap prototype :-) Patrick
