Well what do you know. I hacked up the cable headend OS and software last night, so it runs over the local interface instead of Ethernet. This morning it's still online.
I guess 3C509 issues? I need another Ethernet card to try. #analogcable #InteractiveUnix #Unix -
Back on the #AnalogCable #ANIC repair tonight. I figured - this thing is a PC, right? The top board has a UART at COM1? Why not try Ruud's diagnostic ROM [1]?
Turns out Version 4.7, programmed into a 27C256, booted far enough to print out these checkpoint codes:
33 0 2 3 4 6 8 9 A t8ABoot, port detect, video init (there isn't any). 0A is "detecting video RAM" (which is used for stack to test the main RAM) ... and 8A is "no video RAM, test halted".
Good start!

Wild question, does anyone know of a 65C02 variant -- and the reset vector at FFFE/FFFF?
I'm poking around in the General Instrument MVP scrambler firmware and the code seems to be vaguely passable if fed through a 6502 disassembler, aside from some instructions which are undefined on the WDC 65C02S.

Second CFT2100 #cablebox #analogcable arrived for #ReverseEngineering. Sadly this one hadn't been packed very well - broken plastic, and the OSD menus don't work :(
