1) congratulations!

2) Working means what? responds to front panel? runs ROM monitor on=20
terminal? DC power good?

3) hinged lid is NOT steel, no response to magnet.

4) lid and cabinet have matching square clips on side corners. Examine=20
carefully and you'll find them. Also there's nylon clips under the case=20
to provide force (see your private discussion, Sid, with me). Nylon=20
clips are shown on my 4/40 Web page.

5) Photos of new fans on PSU would be appreciated.

Gotta run, congrats again! - regards Herb
