Welcome to schematic lounge, where schematics that have had a hard day at work, drop by to unwind.

This site is a place to access some odd-ball schematics in my collection.  They represent schematics for which I either have an original copy or of which I obtained a copy from a public source.  I don't believe in making money off of dead, departed technical information.  These schematics are provided for your reference.  As I collect more, I'll add them.

If you would like to leave comments, please do so below.

Regards,

The Czesky Fousek

If you'd like to provide commentary, and discuss with others, please do so at the forum below.  If you would like to contact the Czesky Fousek directly, please use the contact form.  I do have the manuals for the T4, the SX-140K, but they were too large to include here.  In the spirit of free info, however, I can send you one if you want.
