[sdiy] Sequential Six-Trak or Max schematics ?

[jbv]

Hi guys,

Do you know where (on the web) I can find schematics
of a Six-trak or a Max to download ?
I've already found a couple, but very poor quality scans,
and quite unusable...
I'd like to check what's available for free before ordering
some original paper schematics.

Thanks,
JB
