Issues with the 9010A
by John Robertson 26 Mar '03

I was tinkering around with a sick Bally MPU board today (a rewired -17 monster for Grand Products 301), and was trying to figure out why the 6810 was not being selected...So I set the probe to DATA, and set a WRITE @ 0000 = 55, and then tried checking with the probe for results. Curiously enough, the probe showed nothing at all for A7 - Tri-state as far as it was concerned. I though maybe the 6800 pod was defective and pulled out another one, same result. A regular logic probe shows everything active. Now, I haven't experimented much with the probe sync, and this might be a flaw - or am I missing something obvious. I did only get four hours sleep last night due to some idiot breaking my shop window at 1AM and had to hang around till 4 for the glass folks...so - let's say I'm not at my sharpest today. Suggestions?

TK-80A NEC computer trainer for Fluke 9000 series
by John Robertson 12 Mar '03

I was never able to find one of these 8080 based test computers, but did win on Ebay a suitcase 8080 test computer made by INTEGRATED COMPUTER SYSTEMS. It looks like it is a 'clone' of the NEC as it has almost exactly the same parts, same memory size, same RAM size, same keyboard, displays, tape in/out, etc. It came with a learning audio tape (no idea what it is yet) but no manuals. It does interface to a S100 buss and it also has a built-in extra board for experiments, including a cute motor with a chopper disc (infra-red). So I am eventually going to finish testing it (mine had a cracked -5 regulator solder pin - easily fixed) and then see if it helps my apprentices learn how to use the 9010A WITHOUT my having to help them. The process in the Fluke 9000 Series Micro-System Troubleshooter Introductory Training manual is self directed after all... So keep an eye out for these suitcases - they might be handy for your shop! Also if anyone has paper on this I'd like a copy either scanned or photocopy. Thanks!
