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!

9100FT Programmer’s Keyboard
by Ian Eure 08 Oct '18

08 Oct '18

I finally tracked down a Programmer’s Keyboard for my 9100. I don’t know how widely it’s known, but there were two different versions of the keyboard. The only photos I’ve seen are the earlier model, which meant that I almost let this one slip away. It was on eBay, new old stock, for $36 shipped! All the info is in the manuals, if you look. I had always wondered why the keyboard illustrations in the Programmer’s Manual didn’t match the photos of the keyboard I’d seen. It’s because I read scans of a later (1991) printing, which has illustrations of the later revision of the keyboard. I haven’t seen a 1988 printing, but I bet it shows the earlier keyboard layout. The various 9100 service manuals list different part numbers: 9100A Supplemental Parts List (May 1988), fig. 5-21, p. 5-53 ---- Lists p/n 5-64995-131. This seems to be the more common version of the keyboard. It has a block of (mostly) 2u keys on the far right, angled RETURN key, and arrows by the SHIFT and RETURN keys. Photo: https://i.imgur.com/undefined.png The Service Manual which this is a supplement to (9100A Service Manual p/n 809210, May 1988) only lists the Fluke stock number, 757120, in fig. 5-20 on p. 5-50. 9100FT Service Manual (p/n 910476, November 1991), fig. 5-18, p. 5-49 ---- This has new stock and parts numbers. s/n 887216, p/n E04008051. The later revision more closely resembles a 1990s 101-key PC keyboard, with separate numpad and arrow keys. It seems to work fine on a 9100A. Since this an uncommon keyboard, I naturally tore it apart and took some photos of the inside before even plugging it in. These are available on https://www.dropbox.com/s/sa34h6252476012/9100FT-Keyboard.zip?dl=0, and probably ought to go into the TTL FTP. It seems to be second-sourced from KeyTronics, which might explain the lack of documentation (schematics, etc) in the Fluke service manuals. Even though it looks like a PC keyboard, it uses uncommon capacative (hybrid mechanical) switches mounted on a metal plate, and feels much sturdier than the 1990s rubber dome board I was expecting. The controller is an 8031, with the program in a 2764 EPROM. I’m going to see if I can dump it, though it’s soldered in and I’d prefer not to remove it. There are two DIP switches which are accessible via a panel on the bottom. I have no idea what (if anything) they do. I’ve built a few keyboards from kits, so I was hoping that with a good look inside, it might be possible build a reproduction with the same microcontroller and program. While the 8031/2764 is excellent news for this, the rest is a downer. There’s an Exar 22-00958-000 IC which handles the capacitive keyswitches and provides keypress data to the 8031. It looks like the switches and controller are hard to come by, which renders the program on the EPROM useless. Still, maybe someone could adapt another KeyTronics board, as they seem to be fairly similar. Here’s a couple pages I found that have info on KeyTronics keyboards, and might be useful. http://www.vcfed.org/forum/showthread.php?58612-Key-Tronic-KB3270-Plus-ROM-… http://www.seasip.info/VintagePC/kb3270.html https://geekhack.org/index.php?topic=37968.0 -- 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/

Re: [Techtoolslist] Fluke on Mario Bros.
by David Shoemaker 20 Apr '18

20 Apr '18

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 :-#)#

I've owned this for about 18 months. All functions work correctly. The only negative is a small tear in the surface of the membrane keyboard (pictured). All keys work correctly and have done for the time I've owned the unit. Price: $235 for the main unit ONLY. $280 for the main unit plus the 3 out-of-circuit test leads (16, 20 and 24 pin; each 3' length). Shipping extra. I charge just what Fedex charges me. No charge for packing materials. Payment terms: Paypal gift, USPS Money Order, Paypal purchase (buyer covers Paypal fees). Trades: always open to trades for other test equipment but I can't think of anything I need at present. FYI I have also listed the item is also listed on the KLOV forum. link to pics/videos: https://drive.google.com/open?id=0B4f6QpD8ItHybWNDZWZiMERiQTQ thanks! _______________________________________________ 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/

Fluke Compiler Wrapper
by IAN EURE 11 Oct '17

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/

FA: Fluke 80188 pod (and 80286 question)
by Tony Jones 09 Oct '17

09 Oct '17

I just listed it on eBay. I doubt it's going to rock anyone's world but it passes self test and is in nice shape. Includes manual. http://www.ebay.com/itm/182819058155. $50 reserve + shipping. I have a 80286H pod + manual that I should hopefully have fixed soon if anyone is interested, I was surprised at the $152.50 + shipping the recent non-working one sold for. I noticed it was a standard 80286 (all the one's I've seen are the hyper/H version). Anyone know the specifics? _______________________________________________ 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/
