Using Fluke 9010a with Oscilliscope
by Matt Rossiter - Verio Southern California 12 Apr '00

12 Apr '00

Has anyone successfully been able to use the trigger output on this tester? I'm using a 465M oscilliscope and I've got it to listen to the Fluke troubleshooter, but I'm not seeing an signal coming from the probe tip. I'm just wondering what the secret is.

Thanks for the info. The seller didn't know the range. One of the reasons I didn't buy it. I might get the kit from weedtech.com though.

It will probably be udpated in the future. But 20 Mhz will cover me for now (Pac Man has 6 Mhz signals). One warning don't try to use an OPTIX 16x1 display as they are actually a 8x2 so now I'm stuck rewritting code.... What is the freq of that counter on E-bay?

Yehaw! I got a 5400a
by FBowen＠checkfree.com 31 Mar '00

31 Mar '00

and it passes self test! I bought it off e-bay with a description reading: The front panel lost a battle of wills with our famous Arizona sun and is much curvier than HP ever planned for it to be, and the carrying handle is broken, leaving a handle "stub" on each side. I didn't think much of it until I opened it up and realized the front panel is METAL! Holy cow, somedbody must have dropped it (explains the broken handle too) or really wacked it good. Fortunately the only damage seems to be the unstable signature LED is broken or even just a disconnect between the LED and the trace. I'm definitely getting a signal to the trace. Just looking forward to doing more repairs... To UNSUBSCRIBE from techtoolslist, send a message with "UNSUBSCRIBE" in the message body to: techtoolslist-request(a)flippers.com.

Re: Wico XY Pattern Generator Schematics?
by John Robertson 30 Mar '00

30 Mar '00

Have you tried asking WICO? 1-800-FOR-WICO. I would like a copy too. I have the Electrohome XY Vecotr test generator (borrowed, must return someday) but it is not a nice layout inside...single side circuit board with dozens of jumper wires...I would be willing to take a couple of hi-res pictures if someone wants to try and work out the schematic, there are no traces under the IC's...just time consuming.

Wico XY Pattern Generator Schematics?

Does anyone have copies of the manual or schematics for the Wico XY pattern generator? Mine has some noise in the output and having the schematics would be nice when I start working on it.

9010A - mods to pods...
by John Robertson 27 Mar '00

27 Mar '00

Well, technically speaking it is not a pod mod, but I did make an adapter for the 6502 pod to enable me to use that for checking out 6504 based processors. The main difference between the 6502 and 6504 is the 6504 has only 12 address lines, and it is packed in a 28 pin package. I used a junk circuit board that had originally a 6802 and 6821 side by side, cut away the remnants of the rest of the board, and by adding a ZIF on the underside of the board in the 6821 mount after setting it to straddle the data pins correctly, and cutting the other traces. Then jumped the address, power and a few signal paths. Took about 1 hour start to finish, and it seems to work just fine. So now I can service my Allied Leisure MPU boards better. Need to build an I/O map next...the RAM and ROM test fine, but LOTS of I/O ports need to be figured out...

Re: ISO: Frequency counter, Pace MBT solder and extractor
by John Robertson 23 Mar '00

I don't know how much use a frequency counter is for you, I use mine about every four or five months to check if an interrupt generator on Bally/Stern MPUs is working, but nothing else these days. Older silver age videos (B&W non microprocessor based) were the biggest user of this tool, good for following the clock divider...Often a frequency counter is built into other test items-scopes, multimeters, etc, that is the route I would go to reduce shop clutter... As for the Pace, well, the tool is not that inexpensive. I'll buy the station from you if you want to get rid of it, I have a shop use for the toy...

ISO: Frequency counter, Pace MBT solder and extractor

Is this an adequate frequency counter for videogame repair purposes: Heathkit Frequency Counter Model IM-4100 http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=289956727 If not, what would be a good brand/model to get that is available and cheap? Also looking for the solder gun and extractor for a Pace MBT-200 at a reasonable price. I bought one of Clay's stations a few months back but haven't had much luck finding these at a decent price.

The Heathkit counters are ok; I have one I love. But... A) This is one of the cheap ones (not a major issue) B) They never specified its maximum frequency C) They never said it worked D) They never said if it was originally a kit or sold pre-assembled E) If it was a kit, depending on who made it, will determine a lot as far as how reliable or repairable it will be F) I've never used a counter on a video game... for anything. I'm not sure what you're going to use it for. I'd spend my money on a good DMM, scope, transistor tester, cap meter, signature analyzer or beer, before getting a counter for use in VG repair. -Mark To UNSUBSCRIBE from techtoolslist, send a message with "UNSUBSCRIBE" in the message body to: techtoolslist-request(a)flippers.com.

Some of the universal eprom programmers also test many devices.
