KK-6502-A NOP Atari Compatible

I know how to make one of these that will give Address bus signatures that match the Z80 sigs and will match all of the Atari documentation sigs but I would like to know the real opcode that Kurz-Kasch used for this NOP (data bus wiring) If you can help please let me know.

OK what about Kurz-Kasch Intelligent NOP's anyone have one of these? _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

>From what I understand they have a DIP switch that allows setting the data bus lines Looks like they made a 6502, Z80, 6800 and 8080 Programmable NOP's Anyone have one of these ?

Manual here http://www.mcmelectronics.com/content/ProductData/Manuals/94-410.pdfTips http://www.mmccs.com/mmarc/n0ss/hakko_808_notes.pdf The manual says the heater should measure 40-50 ohms on the 120v model and 210-270 on 240v models. If that looks good I'd check the temp control pot.

I plugged mine in today and it stayed cold. The pump works fine, so I know it has power. The heater seems to be in good shape so I suspect the circuit board that supplies current to the heater. I've tried measuring the voltage on the red wires that supply the heater, both AC and DC and there doesn't seem to be much there. Does anyone here know (or could check) what the voltage on the red wires should be? Or maybe the heater is bad and the board doesn't provide any current if it is open (or short). A value for the resistance across the heater would be good to know too. Has anybody here had a similar experience and knows a quick easy fix?
