Alpha Electronics Dynamic Integrated Digital IC Tester on eBay

I chatted with the seller and he confirms that it does NOT power up. So chances are the battery backed up system ROM has failed. Item 390623172259 He reduced the price on his own from the original asking $59.95 to $19.95. Pity. I was hoping to find a good one to extract the program from to save mine... If someone here buys it and CAN extract the ROM data I'd sure like a copy!

Re: [Techtoolslist] Fluke on Mario Bros.

Looking at the manual for the Z80QT pod and the schematic I think I am getting an expected result. I hooked up the pod and hit BUS to run the bus test. I immediately get back CTL ERR showing 00000010 this is the HALT line. Looking at the schematic it appears HALT and INT are both tied together and pulled high. So the fluke can't exercise that line. Any way to ignore that error and verify the rest of the bus test? Oh and according the manual maximum clock frequency is 8.0 mhz. Does that mean this pod support Z80A/B/C ? From: David Shoemaker [mailto:davids@oz.net] Sent: Wednesday, November 16, 2011 10:38 PM To: 'Technical Tools Mail List' Subject: Fluke on Mario Bros. Anyone know if you can use either the base z80 pod or the z80qt pod on Mario bros? I know it uses the Z80A but I don't know what the pod is rated at.

Fluke 9000A mystery adapter (for me at least ;-)
by John Robertson 20 Feb '18

I have a pod module here called "Z8 I/F ADAPTER" Fluke #9000-200/AB. It has no cable to the base, just a 40 pin CPU cable. Inside is a couple of RAM chips, and some Fluke hybrid interface ICs. Any guesses? John :-#)#

HELP : B&K Precision 560 IC tester firmware upgrade
by Fabrizio Vasile 01 Aug '13

01 Aug '13

Hi all, since I'm going to get a B&K Precision 560 IC tester with a 2.00 firmware onboard, I'm wondering if is it possibile to upgrade it to the latest revision and where to get this update, I knew for sure some units has 2.50 or even 3.00 firmware revision. Any help would be appreciated.Thanks. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Thank you for your post on the 10529a. I've only played with them a couple times. I was hoping they would be helpful but I was loosing hope before your post. I will spend more time using them and learning the quirks.
