Chuck really has the right answer here. UART chips aren't going to patch over that. KJ

11/04 Project

> From: William Degnan > 1) the console rom does not go in any of the 4 bootstrap slots, these > should be empty for now. There is a special console rom slot. Just to clarify, by "slot", you don't mean 'backplane slot', you mean 'socket (on the card)', right? Also, note that the console/diagnostic ROM is a different size (bit-wise; I'm not sure about the physical package) from the bootstrap ROMs. > 6) possibly the only switch to worry about now is the power on auto > jump to console switch. I'd leave that, too, until we get the software console to run when started manually - at the moment, the ROM's not working, so that switch is irrelevant. Noel

by cclist＠sydex.com

Anyone looking for these old WD controllers? I've got a mixed tube of the WD37C65-02 parts and the SMC FDC37C65B equivalents. $10+shipping takes the lot. --Chuck

ISC Intecolor 8300 terminal

by arcadeshopper＠gmail.com

I recently picked this up from shopgoodwill and it has an older power plug. It is NOT a standard plug as shown in the picture below that is too tall and pins are smaller etc.. Anyone know the name of this 'standard' so I can find a cable? Or possibly have one around I can get from you?
