Title: Commodore 1960 monitor
Post by: Blacklord on March 17, 2007, 10:52 AM
Got an opportunity to pick one of these up for a reasonable price. Has two connectors (one being the standard Amiga 15 pin one) & a 9 pin connector as follows :

  Pin 1: Ground
  Pin 2: Red Prime
  Pin 3: Red Video
  Pin 4: Green Video
  Pin 5: Blue Video
  Pin 6: Green Prime
  Pin 7: Blue Prime
  Pin 8: Horizontal Sync
  Pin 9: Vertical Sync

The question is, is the 9 pin connector going to work with the 128's RGBi output ?

The monitor will scan between 15 kHz to 38 kHz Horizontal & 50 Hz to 87 Hz Vertical

cheers,

Lance

According to this URL some 1960 monitors may or may not have the digital RGBi (TTL) switch.

Is there any way you can check on the back of the monitor before you buy it?

I can't say for certain, but at least the common signals match, pin-wise. The other three:

- Red Prime (2) will be grounded
- Green prime (6) will map to Intensity (sounds logical)
- Blue Prime (7) will map to monochrome/compoite

Maybe that helps?

Well, the monitor will still be useful for the A1200, so I guess I'll try plugging the 128 in - will report back with the results.
