Overclocked TI Silent 703 at 1200 bauds?

[William Sudbrink]

I just checked my 3 703's... all are switch 4 unused and functioning at 300 baud.  If you would like to trade one in order to have the classic 300 baud experience...

Yes, I tried switch #4 and that did not do it. I opened it up, no other obvious jumpers. The processor doesn’t even say TMS 7041, it’s a custom numbered part. Not that I am complaining, I am fine with my blazing fast gamer’s TI 703 with overdrive. I’m just surprised they did not label it anywhere on the machine or even change the product naming. Like TI 703 Turbo or something!
