[net.micro] C64 monitor connection

ABN.AFZA-GA%usc-isid@sri-unix.UUCP (12/14/83)

I have seen (and purchased) the Commodore 5 pin DIN monitor connection
to the three RCA type jacks that  separates  the  signal  into  audio,
chrominance,  and luminance.  When used with the Commodore monitor, it
gives a very sharp color video display.   The  November  83  issue  of
COMPUTE!   discusses the reason why this is so and mentions that for a
very good monochrome display, the  luminance  signal  only  should  be
connected to a monochrome monitor.  I might mention that the cable was
very  expensive  from  the  local  Commodore  dealer  ($15.95)  so  an
alternate source might be advisable (Radio Shack maybe?).

I bought the cable because it separates the signals and will allow  me
to  hook  up  my C64 to my stereo and to a monochrome monitor.  I have
not bought the monochrome monitor yet but I intend to do so to use  in
conjuntion   with  programming,  word  processing,  spreadsheets,  and
anything else involving strictly text.  I plan to just use my  tv  for
anything  involving  color  graphics.   I have seen the Gorrilla amber
monitor at the local computer store for $99.95 but have no  experience
with  it.  I would appreciate any information on it or any inexpensive
monochrome monitors.  I'll post a summary if there is enough interest.
Thanks.

I hacked a direct video injection to a $70 Sanyo b&w tv. Works good
using just the luminance output. I got a 5pin DIN cable from Radio 
Shack for about $5
 
By the way----- does anyone have any idea what the intended use of the
audio in pin on the C-64 plug could be?  I just don't grok what it's
point is.

I have encountered a very wierd behavior on my C64. I stupidly bought
a game on tape just before deciding to buy a disk. I'd like to copy
it to disk but have hit some snags. My main question right now is
this: why does LOAD from tape behave differently in immediate and
program mode? Specifically, I am trying to load from tape with
'LOAD "",1,1'. Typed for immmediate execution it loads some data
(as prescribed by the header), then returns control to me. In a
program, however, it reads data for a much longer time, eventually
stopping with the keyboard hung. I'd ask Commodore for help, but they
never responded to a previous letter.

About the audio in on the DIN plug. The User's Guide somewhere
notes that you can read this input for envelope control on
synthesizer #3 or some such sensible thing. If I had the book
here now I'd look it up. Sorry.
