Hi all,
I've finally got my Taxan CGA monitor working again and I would like to use it with my Olivetti M24 / AT&T 6300. I did a quick search online and found the instructions for making a converter from the DB25 to VGA, but nothing about a converter for a CGA monitor.
According to the literature; my Taxan CGA monitor should be compatible provided the DIP switches are set correctly (see page 3): http://www.minuszerodegrees.net/man...er Vision IV and 630_640 - Service Manual.pdf
The pinout reference I am using for the M24 is here: http://www.olivettim24.hadesnet.org/docs/video_pinout.pdf
Looking at the pinouts between the M24 DB15 / CGA shows plenty of commonality (R,G,B,VS,HS) however the M24 doesn't seem to have a pin for intensity. The lack of intensity pin tells me that it adheres more to the VGA convention; hence why the VGA adaptor is easily crafted.
Normally when you bought your Taxan monitor you could get a multitude of different cables (as options) however mine only has the usual DB9 for CGA. As such I need to make a cable that goes between the Taxan DIN-8 to the M24's DB25. I assume I just connect the usual R,G,B,VS,HS and GND and see what happens? With the intensity pin left floating is there any danger I could damage my monitor?
I'll most likely just give it a try, but I thought I would seek advice first...
