Tony, All John meant was that (you, me, anybody) considering buying a Fluke cpu pod might want to check the Fluke 90 series as an alternative to the ridiculous prices people want for the Fluke pods. End of story. Tim -----Original Message-----

John. Who is the "you" here? Me? Kevin? Both of us have 6809 pods so I'm not understanding why we would want the 90? Can you elaborate? On Mar 17, 2016 2:47 PM, "John Robertson" <jrr@flippers.com> wrote:

Man those things have gone up in price. I bought 2 about 3 years ago for $350 total.
This was a very good deal 3 years ago. Last one to sell on eBay (untested/as-is) went for $500.
You may want to keep an eye out for the Fluke 90 series portable MPU analyzers...

oic. I know nothing about the 90, what are the functional differences if any? The display seems very small (prior ebay link). don't really want to touch the 'ridiculous' bit with a 10' pole ;-) thanks!

The 90 series was designed in Canada (Edmonton, Alberta) and worked fairly well as a clip-over the CPU type of exorcisor. I've got pretty much the complete set and they can be handy at times, especially if you don't have the pod for your 9010/9100. I have all the pods so these basically sit on a shelf. These only work with CPUs that can support having their address and data lines floated when you select a particular CPU pin, AND that pin MUST have a pullup resistor on the UUT PCB. In some cases that pin was simply wired to Vcc, and then to able to use the 90 you have to cut the Vcc trace and add a 10K pullup. The 90 works by cycle stealing, it runs when the CPU is on the opposite cycle. Rather cute in fact - the game can be running and you can run a RAM, ROM and I/O test at the same time! It has a RS-232 port as I recall and if more folks on the list had these then I probably would have played more with mine and we may have made some use of it here. Perhaps a show of hands of folks with the Z80 or 9809 Series 90? If there is interest perhaps I can contact the designer and see if he is any more interested in sharing info on the unit than he was the last time I asked about six years ago...what I'd like him to do is write the story of the 90 series device, and what the heck, I will try contacting him again in any case. It would be nice to get the story out!

thanks for posting this technical info John, much appreciated! _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
I have a Z80 Fluke 90 that I bought about 20 years ago. Since then I've also stumbled across a 9010 and two pods (Z80 and 8085). Is the Z80 Fluke 90 hardware the same as the 6809? It would be nice to mod a Fluke 90 to support both or maybe even the 6502. Anyone have a firmware dump for the 6809 Fluke 90?

Fluke 90 Series dumps are on the FTP site. I have the 6809. I don't know if it can be rewired, I was able to modify a spare 8085 to become a Z80...and then I found a Z80 Series 90. Gah. John :-#)#
