Galaga Won't Run on the 9010A
by Mark Hooks 10 Sep '06

10 Sep '06

I attempted using a new Galaga test script on my 9010A and found I can't even get the Z-80AA pod to run the UUT. This is a known working board and all I get is a white screen when I enter the command to run UUT @ 0. This is the Namco version board with the pod plugged into the 4M slot. I tried resetting the board but get the same result. Has anyone figured out a way to resolve this?

HP 10529A Logic Comparator Question
by Matt Rossiter 30 Aug '06

30 Aug '06

I've been using this device for years. Today I came across an idea that I hadn't thought about. Normally I set the TTL outputs with the two dipswitches, put in a "known to be good" TTL chip and compare with the one on the board. If any of the outputs are bad, the corresponding LED(s) will light up. What about just setting TTL outputs, but not actually putting in a chip to compare with? So, for example, I am looking at a 74LS32 chip on the board, the outputs are pins 3, 6, 8, 11. Without a chip in the Logic Comparator, the 3, 6, 8, 11 LED's should all light up. But today I noticed that only 3, 6, and 8 lit up. I've been suspecting that the output on pin 11 was bad, but when comparing with a good 74LS32 it didn't light up either (indicating it was good). So it turns out that the output on pin 11 *was* bad, but the comparator didn't catch it with the good chip inserted. Without a chip inserted, it was the only output that *didn't* light up. Has anyone else tried this "reverse" method before? (and yes, all my LED's on the comparator are working fine. I tested other chips just to make sure).

9010A Code Generator Question
by Matt Rossiter 30 Aug '06

30 Aug '06

This is a very handy tool to work with when you want to do some quick tests. I love it. I have just one itty bitty suggestion, unless I'm just doing something wrong. When you generate a test script for a game, say Tempest, the ROM Program names it automatically creates are generally "illegal" when they are compiled through FIDE. I guess it has to be a certain length? So, I just have to edit each ROM program name so that it can compile the script and send it to the troubleshooter. For example, I would normally take a generated name like 136002123 and manually change it to ROM123. http://tech.quarterarcade.com/Tech/CodeGenerator/Default.aspx?g=3057&set=te… James, would it be possible to add an optional function that could automatically truncate the ROM Program names? Maybe have something where it adds "rom" to the beginning and the last 3 or 4 characters of the rom name to the end? I don't mind doing it manually, or maybe come up with a script of my own, but that would be super cool.

Obsolete parts source
by Rodger Boots 21 Jul '06

21 Jul '06

Ran across this by accident (oh, alright---got an email from them), here is an interesting site selling obsolete parts---could be useful. http://www.americanmicrosemi.com/home/ They actually stock the first microprocessor, the 4004, and the supposedly unobtainable 6118A display drivers the Gottlieb system 1 pinballs used. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
