Alpha Electronics Dynamic Integrated Digital IC Tester on eBay
by John Robertson 17 Feb '20

17 Feb '20

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

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 :-#)#

Fluke Compiler Wrapper
by IAN EURE 11 Oct '17

I hacked up a tool that will run 9LC.EXE inside DOSBox, so scripts can be more easily compiled on non-Windows and/or non-x86 platforms. From the host OS, it runs just like 9LC does, warts and all. It’s public domain, and should run on most UNIX type systems. https://github.com/ieure/fcw — Ian _______________________________________________ Techtoolslist mailing list Techtoolslist(a)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/

WTB: Clock module
by Ian Eure 29 Sep '17

I’m looking for a cheap clock module for parts. 9000 or 9100, working or not. Let me know if you have one you’d part with. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)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/

Slowing down a Fluke Z80 pod?
by David Gersic 19 Sep '17

19 Sep '17

This is going to seem like a strange thing to want, but is it possible to slow down a Z80 pod? I have a 9010 and the Z80 pod for it. As far as I know, both are working fine. I don't have anything with a Z80 in it to test to prove that. What I picked these up for is to use with a Signetics 2650 adapter (http://www.arcades.plus.com/s2650_fluke_adapter.htm) on Zaccaria boards. It seems like this should work, but in practice it's very unreliable. Test reading data from ROM on a known working board, sometimes I get correct data, most of the time I get random garbage. If I read a byte from the same address 10 times, maybe one time will be correct. Test RAM, it'll go a few bytes in to the test, then "fail". If I loop on that, it'll eventually pass, then fail a byte or two later. This seems to be essentially the same symptom as displayed by the ROM reading test. The adapter board is based on the old Fluke "Troubleshooter" article from 1983. As far as I can see, the board is doing what it's supposed to do, moving signals from the Z80 to where the 2650 expects them to be. So what I'm thinking is that the Z80, running at a faster clock speed than the 2650, is just over-running what a board designed for a slower processor can deliver. Is it possible to slow down the clock speed on the Z80 pod? _______________________________________________ Techtoolslist mailing list Techtoolslist(a)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/

Check you clock signal on a scope, does the board have a two speed clock when access slow ram? Everything I have random read issues it's always a buggured clock.. it maybe good enough for the 2650 but not for the z80 On Sep 17, 2017 10:47 PM, "Rodger Boots" <rlboots2(a)gmail.com> wrote: It may be easier to speed up the board....cool the memory you're trying to test. Might just give you enough timing-wise to see where the hard failures are.

If this is someone's here: http://www.ebay.com/itm/192309556789? they need to take new pictures as it looks like the display is fading out on the ends - won't help the chances of selling it!

Fluke pods on eBay
by Andrew Welburn 15 Sep '17

15 Sep '17

hi all, I am raising funds for another project right now and have decided to let my spare Fluke CPU pods go to the highest bidder on ebay, its the fairest way to do it (but i curse their fees!) Please take a look at my auctions: https://www.ebay.com/sch/andys-arcade/m.html Also of interest to this group will be an Atari CTF-1 test rig that i think might have to go on ebay this week, i am fixing it up as we speak, its not listed yet. Enquire off-list if you are interested. thanks, and sorry for spamming up your inbox, but these auctions are quite pertinent to the readership i feel ;) -- Andrew Welburn andys-arcade _______________________________________________ Techtoolslist mailing list Techtoolslist(a)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/
