In 2021, [Neil Cohen](/indiv/neil-cohen/)
 sent a few TS 2068 computers in various states of repair. One computer had a home-brew RGB converter built inside and around the composite video output jack. Here’s what it looked like when I opened the case.

RGB converter built in to the TS 2068 with a DIN plug for output.I extracted the board, disconnected it and traced the circuit as best I could. Here are some more photos and the schematic.

 As you can see, there are three integrated circuits and a few discrete parts.

In mid-2022, [Tim Swenson](/tag/timothy-swenson/)
 scanned issues of [CATS](/periodical/cats-newsletter/)
, the newsletter of the [Capital Area Timex Sinclair User Group](/usergroup/capital-area-timex-sinclair-users-group/)
.

Among those issues was an article about several club members who took it upon themselves to design and build their own RGB converter. [Herb Schaaf](/tag/herb-schaaf/)
 wrote up the results, which appeared in two separate issues.

The first article, “[Retrace Lines: 2068 and RGB Monitor](/article/retrace-lines-2068-and-rgb-monitor/)
,” described their effort and the circuit.

The actual schematics were published a few months later in “[The Art Gallery.](/article/the-art-gallery/)
“

As you might have guessed, the circuit those user group members designed is the same one built into the TS2068 I received from Neil Cohen.

### About The Author

[David Anderson](/author/david/)
I'm a big fan of the Timex/Sinclair computers: my first was the TS 1000. I love building things for my TS 2068 and sharing them with others on this site and andertone.com.
