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 :-#)#

Fluke 68000 pod version 6 firmware
by Tony Jones 25 Jan '18

25 Jan '18

Hi. I'm repairing a couple of 68000 pods at present and it reminded me that I'd always wanted to dig deeper into this. Does anyone have a 68000 pod running version 6 of the firmware? It's documented in rev 2 of the pod manual, and the code resides on larger 2764 EPROMs to implement the additional QT. I've owned six 68k pods and I've never seen anything higher than rev 5. You can get your pod version (on a 9010) by reading F0000012 (after taking the pod out of self-test of course). Output format is hex x0 where x is the major version. Not sure how to do this on a 9100 as it won't process addresses outside of what it knows as the 24bit address space, maybe TL/1. I need to dig deeper into the schematics to see how this is implemented on the hw (and what the upgrade path is). The three 68000 pods I have at present, all have the pads present for the larger 28 pin sockets (on their cpu boards) but only a 24 pin socket installed. The cpu board part# and the U9 PAL part# are the same in both versions of the manual, only the EPROM part#'s differ which is curious as obviously the pin addressing differs between a 2732 and 2764.

Xeltek Superpro 2000+ repair
by John Robertson 29 Nov '17

29 Nov '17

Anyone using one of these, or has one in a junk drawer? Mine appears to have either a bad 29F040AT-90 or 29F080T-90. Machine gets to Write Memory OK! 7FFFF, in memory test then craps out saying Verify Memory ERROR! 0 0 0 The device programs up to 2MB with no problems, but it gets bad writes on 4MB devices Verifies fine though. My hope is someone else has the sub-memory board (labelled SPABUF) on a used/dead machine or has one or more of these TSOP style chips in their junk box they would sell and ship to me. I am going to get a newer Xeltek (600P) but this old timer (2000+) is nice to have as a spare in case something goes wrong with its replacement.

Assman "Ribbon Cable Tester"
by John Robertson 23 Nov '17

23 Nov '17

Anyone else playing with one of these? It is a ribbon cable tester I found on eBay and you teach it for each cable being tested. It only remembers the current cable under test. Inside it says "Ribbon B2 Hobbes CO." on the main PCB. Doesn't appear to be any town called Hobbes in Colorado...(Calvin & Hobbes pops up of course) This device runs off 9VDC wall wart or has a battery which you can also run it off. My unit drains the battery rather quickly when off and the wall wart is not plugged in. The 9V battery is not used to retain memory, that function is covered with a HM6265WH-70 CMOS RAM which is maintained by a 10Ufd cap that is charged by a diode to the 5VDC buss. That size cap drained from 4.8VDC to 2.6VDC overnight. If you want to store longer, then use a bigger cap. The annoying thing about this tester is the 9V battery drainage means there is always a LOW BATTERY warning on the display. So I have to sketch out the 9V battery circuit and figure out why there are so many jumpers installed from the factory for that battery. I have uploaded manual and photos of the outside and inside of the gizmo in case you are curious to: ftp://ttl.arcadetech.org/TTL/Test_Equipment/Assman We are producing ribbon cables for arcade games and it will be nice to have this working correctly.

FS: Fluke 9100A w/-003 Parallel IO and clock module
by Chris Loggans via Techtoolslist 16 Nov '17

16 Nov '17

I've been going through all of my Fluke equipment recently and have decided to sell off one of my spare 9100A's. This unit has 4MB RAM, version 6.1 OS, a working floppy, and has been converted to a CF hard drive using a CF to SCSI adapter. I'm also including a 9000A clock module and a 9000A-003 Parallel I/O module with a calibration module, a 40pin module, a 14pin module, and a flying lead module. The only thing I don't have is a video card for it. I'm asking $1600 + actual shipping for everything. If you are local to Northern Virginia, you are welcome to pick it up and save the shipping costs. I've also been converting my other 9100's to use the HxC floppy emulator (http://lotharek.pl/product.php?pid=121) For an additional $140 to cover the cost of the unit and an SD card, I'll swap out the standard floppy for the HxC and include and SD card with images of all of the standard 9100 software to eliminate the possibility of the 30+ year old floppy failing on you in the future. Please email me off list if you are interested. Pictures can be found here: https://www.flickr.com/photos/138272997@N04/ (Let me know if you have any problems with the link to the pictures. This is my first time trying flickr.)
