I don't know if you guys have this same experience, but I haven't touched my 9010a for months. I went to fix my Midway Double Play last night and for some reason now this tester won't work. Just for no reason at all. AUUUGH! Fortunately, I happen to have my Fluke 90 series Z80 tester. I'm hoping someone on this list has had to become familiar with the 9010a service manual. If you feel like giving me a hand, you might want to refer to page 4-32 - 4-35. Here's the testing I've done so far. Symptoms - 9010a powers up but only displays a zero with an 'x' in the middle. The keyboard doesn't work except when toggling the probe pulses high or low. 9010a self test - won't respond to key presses. 90 series uP tests: Bus Test - Pass Ramp Test - Pass Memory Test - C000-FFFF Pass Memory Soak - C000-FFFF Fails - Hmmmmm. Is this normal? I/O verify - writes data to certain I/O addresses and then reads the data to check to see if it comes back the same. The Pod/Probe PIA section passes the I/O verify test (100C0 - 100C3) The Display/Keyboard section Fails the I/O verify test (10080-10081). The Magnetic Tape controller also fails (100A0 - 100A1). What appears to be happening is whatever gets written to the display/keyboard assembly will not get read back correctly. Here's something weird. If I do a write @ 10081 Data=00 (reset command to the display/keyboard) and loop it for a while, then immediately reset the "mainframe" (as they like to call it). For about a second the Normal display comes up and then blanks out. I can also send commands to the magnetic tape controller and it will rewind. So it seems like the 'writes' are all working, the reads are screwy. I'm mainly concerned about the keyboard/display assembly. Does anyone have any advice on this one? Could I have a bad ram chip somewhere? I already tried replacing the Z80 microprocessor. Thanks...

Would anyone care to take a guess on this one? Even if your guess might be wrong, maybe it'll spark some ideas.

Hi Matt, Do you have a second Fluke? (we have four at this time) you could mix and match. With respect to the I/O tests, they are only valid if there is a PIA of some sort as the I/O interface, a TTL latch/buffer won't show up the same. I have one 9010 with a display problem that shows up when it warms up, but if yours is dead from the start, then I suspect cold spray won't help you... Have you tried reading the ROM checksum with the Series 90 and comparing it with an archived set? I can email you a set for comparison, I have found that ROM can knock out a system if it does not release when unselected. John :-#)# At 05:55 PM 10/04/01, you wrote:

I've tried doing checksums and comparing them with the values on page 4-10 in the manual. In the manual they are referred to as signatures and they give the memory address of each rom. I'm not getting the same values, so maybe you can send me what software you have and I'll compare them that way. What type of eproms do these use in case I need to burn a new set? Thanks.

Hello all... Just wanted to get thoughts on using a Variac... I wanted to get one for working on monitors. I would be using it to force linear power supply to run or hopefully to dial in different AC supply voltages for vector monitors. Is is worth finding one with isolation or just run along with a regular isolation transformer? Would 5 amps cover most concievable applications for game work, they sure get expensive fast....

A Variac is a single winding with a movable center tap. It offers NO isolation whatsoever. Use of an isolation transformer, even if you don't need one, would be an excellent idea. You may want to use a couple of isolation transformers, one for the monitor and one (or more) for other outputs. Another great use for the Variac is to supply reduced voltages for such thing as monitors from Nintendo games (100 volt Japanese standard). Some power supplies (like the switcher in Taito's Space Tactics) also use 100 volts. 5 amps is more than enough for most "classic" games. Some of the newer stuff where the seat or entire game moves around probably would need more. Max wrote:
