SYM-1 power connector? - test-drb@ccmp.vtda.org

29 May 2002

Hi Dan
 The power connector you need is the 12 pin one at the center.
I was wrong about the 44 pins. The 44 pin ones are for expansion.
Here is a list of the connectors:

 The RAM sockets can be filled with 2114's. I think Jameco still
has these. The RS-232 will drive +5 to 0 if the other end will
take it, otherwise, you'll need a -12V connected to the -VN pins.
You then change the jumper GG to 40.
 Data for the basic ROM's and parts of manual can be had at:

 If you need other things, let me know.

   Also, check to see if you need to have the BASIC
ROM's. These
boards normally only came with the monitor ROM and minimum
RAM. One usually added the parts for the serial as well ( some
transistors and resistors ). 
Looks like I need to add some parts.  I've put up some pictures of
the SYM-1 at

   http://www.decodesystems.com/sym-1.html

The board appears to be minimally populated.  Besides the power
connector, specifications and instructions for adding the BASIC ROMs
and the serial interface would be appreciated.  Thanks!
