[sdiy] ASM-1 schematic question

[Aaron McCann]

Hi all,

I noticed that the ASM-1 schematic on the homepage differs slightly with two
that are listed on the site that sells the PCB (ASM-1 & ASM-1a.)  Are these
just newer versions?

I did check the archives before posting, but didn't find anything so I
apologize if this is an old question.

Thanks,
aaron
