From: "Philip Pemberton" <philpem(a)dsl.pipex.com Right - thanks for the suggestions Peter (and Dwight). I've printed off your suggestions and I'll have a look through them tomorrow. The RAMs are soldered in, though, so it'll be very difficult to swap them. Plus the holes and pads on the board are *extremely* tiny. Guess I was jumping to conclusions a bit... Just out of interest, has anyone got a spare pair of 2732s and an EPROM burner capable of burning them? Just in case it turns out the ROMs (TI branded - getting quite warm, same as the CPU) are frazzled, too. Earliest I'll be able to get my sticky mitts on an EPROM programmer and some 2732s will be around the 25th (think about it)... *sigh* Thanks. -- Phil. philpem(a)dsl.pipex.com http://www.philpem.dsl.pipex.com/
