Tandy 25-1024 sync

[Cruo]

Im still new to this. My Tandy RGB monitor has pins for both horizontal and vertical sync. It seems most game systems have a composited sync pin.

How should I go about creating an adaptor. Do I route the composite sync to the horizontal or vert sync, leave it disconnected, or do I split the wire and route it to both syncs?

The signal connector is a 9 pin, Sub-D type.

PIN           SIGNAL

1            Ground
2            Ground
3            R (Red Video)
4            G (Green Video)
5            B (Blue Video)
6            Intensity
7            N/C
8            Horizontal Sync
9            Vertical Sync

That RGB monitor is no good. Pin 6 (intensity) means that this is a digital RGB moinitor and not an analog monitor.

Do yourself a huge favor and track down a Commodore 1084, these monitors work great.

Thanks.

Thanks for the information.

Commodores are suprisingly hard to track down, you really have to fight for one on ebay.

I found the Tandy in a pawn shop and thought I would give it a try.



Is the commodore 1702 any good?

The Commodore 1702 is a composite display, no RGB. Keep looking for a 1084 their out there, or bid like mad for one on Ebay.

Thanks.
