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 :-)
