[R-390] R-390A Info

[Perry Sandeen]

List,
 
Another somewhat obscure source gem of information
is the Hollow State News re-posts on line.  Most subjects covered were articles on the R-390A, R-392 (including a SS
IC audio output circuit) and SP 600 receivers. Many of the posts are still relevant
today.
 
Articles range from short posts to extensive and
enjoyable tutorials by Dallas Lankford.
 
From its origins the first Y2K manual was
produced. 
 
Considering that most of the issues were
typewritten and there was only snail mail available it was a truly magnificent technological
accomplishment.
 
It’s a good read from a historical point of view just
to see how far we’ve come.
 
Regards,
 
Perrier
