Fluke Z80AA won't run Midway Boards
by Mark Hooks 01 Nov '08

01 Nov '08

My Pod Passes self test, yet it won't run a fully working Pac man board. I've tried it using the run UUT defaults. Am I missing something on the setup, or do I have a pod error? I notice it doesn't pass the buss test either. I get numerous data bit tied low errors. When I loop them, it flips back and forth between Tied Low and OK.

Looking for info on OLD HP 1600A Logic State Analyzer
by kevin spears 01 Nov '08

01 Nov '08

I know this is an ancient boat anchor and probably not worth fooling with, but I couldn't pass it up for $15. It came with (only) one 6-bit input module, but thankfully it appears that the pods are cheap and plentiful for these. (The lack of which was the main reason I gave up on the Tek DAS9100 I've had for many years!) I'm not having much luck finding any documentation for it, however. I've found a few application notes on the agilent site and an advertising announcement on an HP user's site, but that's about it. I know this is a longshot, but would anyone happen to know of a scanned manual for this beast? _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Electrohome G08 pattern generator
by Joe Magiera 15 Oct '08

15 Oct '08

In the back of the Electrohome monitor manuals (both raster and vector) the manual mentions and shows a picture of an Electrohome monitor pattern generator. I have the Wico raster version, and a buddy of mine has the Wico vector version, but does anyone have (or ever seen or know of) the Electrohome version? If so, I'd be interested to hear how useful you find it, and how easy it works. Does it supply it's own power to the monitor, or do you need to supply external power?

Fluke 9100/6800pod and bally mpu help needed.
by mail＠nessandsteve.plus.com 11 Oct '08

11 Oct '08

Hello all, I am hoping someone can help me out. Let me start by describing what has lead me to this: I receive a Bally MPU board P# r2518-35 (Star Trek) that needs repairing. I hook up the fluke and boot it up and get a bad clock error. I notice someone has replaced the 74s37 with a 74LS00, so replcing it restores the clock. I "Run UUT" and the status LED stays on. I check the jumpers and find that 2 are wired incorrectly so I set them right and and I still get nothing. After much head scratching and checking various things with a scope I couldn't see a problem. I replace the cpu and its socket with a spare and it starts the self test process. I continue on and it gets snagged on each step so replacing the sockets on the RAM and PIA at U8 and U11 gets me to the second to last test which failed due to a broken lead on c16. Replacing restored it to fully working. So the MPU board is now completetly working on the bench but if I use my fluke it will not start the self test process. I have tried starting the "Run UUT" from address $1000 and $5000 as I believe this to be the address for each ROM but still nothing. Just to be sure it was not a pod failure I tried a NOS one from the shelf and got the same effect. (Both pods pass self test) Can someone point out something really obvious?

Star Wars Signatures...
by John Robertson 10 Oct '08

10 Oct '08

Checking my files, I find that the "Supplement to STARWARS" #CO-225-02 (1st Printing) has the last two pages on Signature updates. The schematics do not exactly show how to get INTO the Signature state, but I suspect if one reviews Tempest and others that one can be successful. I have not had to service a SW in years and did not need signature analysis at the either, so that is the limit to my knowledge on the matter, but the schematics set and CO-225-02 should help! Atari was expecting you to use the CAT BOX to run these tests...

WTB/WTT: NAMCO Pole Position schematics SP-219
by John Robertson 10 Oct '08

10 Oct '08

I need a copy of these - does anyone have them in their files? Prefer 11 X 17 in. copies. I have the CTS-1 cable for the board and can power it up, but there is a weird RAM select issue that I can't resolve using the Atari SP-218 schematics as they do not document everything! They miss the connection between the Sound CPU and the Data Buss DB0 - DB15. It turns out that DB0 - DB7 is hardwired to SD0 - SD7, but how the Sound CPU access DB8 - DB15 is not shown and yet the ram associated with those data lines ARE available to the Sound CPU. Must be some sort of latch hiding there somewhere! Thanks!

Ram Diagnosis Help Needed
by Mark Hooks 30 Sep '08

30 Sep '08

I'm trying to learn more about how to interpret RAM read/write test results on Atari 6502 based games. Can someone recommend a good text book where I can learn more about how to sort out high from low bits ? The Atari Cat Box manual assumes you have this basic knowledge.... which I don't. I've searched the archives and the FTP site to no avail.

Fluke 9010a issue with pod self test
by Colin Davies 24 Sep '08

24 Sep '08

I just tried my new fluke 9010a with RS-232... passes self test... but when I plug a known working 6502 pod in and do a bus test it reports 6502 pod error 00 (iirc).... Is this a relatively easy fix or should I bite the bullet and move the rs-232 module over to my working unit ? ( Is that all I have to do ? or are there other modifications required to the base unit to accept it ?) I'd rather fix the faulty unit to be honest, as the worker is in really really great condition so I'd like to keep it as a spare and use the other new arrival for now..... Thanks for your help, Regards, Colin _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment
