The model should be printed somewhere around the outer perimeter of the main board and/or on the neck board.
My 2914f boards are tan and my 2938f is green actually. Hard to say which yours is without some identifier though.
I believe the 2938f is a multisync like the 2914f ones but I'm not sure yet myself.
Like you, I can't find definitive documentation anywhere and I haven't had any free time to stuff it in a functional cabinet yet to see what it can do.
All of my Kortek boards have an on board plug for a VGA connector. Hopefully yours does too because then it gets a lot easier.
Maybe someone with more experience/knowledge than me will see this and chime in.
What I CAN say is that CRTemudriver and GroovyMame on a PC are the way to go (once you can get it all configured happily.)
Get yourself a PC with a PCIe slot, an AMD card that Calamity's masterful work flashes to properly and have at it.
EVERY setup appears to be different from the next, but stick with it. The results are astounding.

I just have gotten lucky a few times with a lot of help from folks here.
