Howdy-
I put on eBay a Vectrex with a pause button mod that I installed:

I also fully tested this Vectrex w/ Test Cart rev 4 (running on the 72-in-1 multicart), & the monitor is adjusted & its controller is tested good.
I have 2-3 more Vectrexes on which I'll perform the same mod then sell. Let's see how this eBay auction goes, and, if anybody else here has interest, we can probably strike up a deal.
I could also perform the mod on somebody's Vectrex, but the cost of shipping it to me & back is probably prohibitive. I'm in the Los Angeles area, if any locals want to discuss a pause button mod deal.
Thanks,
-Jason
