I actually carefully looked at the PCB lit from behind before installing anything (WOW! I actually followed the instructions! :-) and didn't notice any problems. I'll check it again and look for any solder shorts. I found it impossible to construct w/o referring to all three images (picture!!!, schematic, and layout with part numbers) so I worry that something was installed incorrectly. Thanks!

ESR meter construction question
by FBowen＠checkfree.com 21 Jan '00

I finally built my ESR meter kit from John and it "works" (it powers up, displays "EA" and then "- ") but when the measurement leads are tied together in order to zero them out the value just keeps fluctuating wildly. The fluctuation is large and happens a few times a second. If I press the button to zero them out it turns the meter off. I'm doing this with the ends of the wires off the PCB (the PCB has not been installed in the case yet) clamped together. Any ideas?

I bought one of those, so did Alex Yeckley. I haven't used it yet, but I did read the manuals and watch the video tape that came with it. I would say they are definitely worth the money. They are brand new, in the box with all the accessories. It is kind of a scaled down version of the 9010, ram, rom and i/o tests as well as a few unique tests like a memory soak and a trace function to identify processor lines. Unlike the 9010 it doesn't replace the mpu, it actually piggybacks it and steals cycles using the dma line. I think I paid $50 + shipping for the whole thing, so it's kind of hard to go wrong for that money. All of the ones for sale on Fleabay were for the Z80, don't know if they exist for other processors or not.

Fluke Model 90 µP Microprocessor Board Tester Showed up on e-gay recently. The description talks about in circuit testing, but does not specify the cpu type. Wonder if it is usefull. Any comments? Mike Text of auction reads: The Fluke Model 90 µP Board Tester is a hand-held, easy-to-operate, tester used to diagnose faults in microprocessor-based devices. The tester is a Direct Memory Access (DMA) device emulator that connects to the microprocessor in the UUT (Unit Under Test). The microprocessor does not have to be removed from the circuit. The tester forces the DMA and WAIT lines on the UUT bus, taking control of the bus from the UUT's microprocessor. Power is supplied by either the +5 volt line at the UUT microprocessor or by and (optional[not included]) external power supply. No connection is required to the UUT other than the microprocessor clip. The Fluke 90 performs the following: Bus Test to determine if any bus line is stuck high or low, or shorted to other bus lines. Memory Test to determine if RAM can be written and read and if ROM contains the proper bit pattern. I/O Test to determine if I/O addresses can be written and read. QuickTrace(tm) to identify the signal name of an address, data, or control signal line and allows the type of signal line to be tracked in the UUT. Detect selected events on the UUT bus by setting and enabling Break-Point, Frame-Point, and SYNC/Trigger Interface functions. Loads the UUT memory over the Remote Communications Interface. Dumps the contents of the UUT memory to a remote terminal or computer via the Remote Communications Interface. > -----Original Message----- > From: James Marous [SMTP:JMarous@midmark.com] > Sent: Friday, January 14, 2000 12:53 PM > To: 'TechToolsList(a)flippers.com' > Subject: RE: Signature Analyzers > > On the subject of KK units....

8086 pod for fluke?
by Noel Johnson 17 Jan '00

Hello All, I am about to obtain an 8086 pod for a fluke 9010. Did any arcade games use the 8086 or am I going to have to trade this puppy away?? Thanks! Noel
