I'm getting rid of a Chamtec PM21 if anyone needs one cheap.
Not the best condition; its pretty beat up.
I've powered it up and had green + blue shapes out of it; not sure if the lack of red is down to the cable or the unit. Haven't really got time to fiddle with it, so sold as is.

All offers welcome.
