Fluke 9110FT SPECTRUM-TX diskettes imaged
by Martin Olsson 10 May '23

10 May '23

Hi all! I bought a Fluke 9110FT setup and with that setup came the SPECTRUM-TX diskettes which I now have imaged and uploaded to the "/TTL/Test_Equipment/Fluke/9100 Series" folder on John's FTP site. Inside the ZIP archive is a ReadMe with more details about the images etc. I haven't tested the images myself but I think they should probably work as the original diskettes was error free. Enjoy! /Martin! _______________________________________________ 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/

ftp site is down...
by John Robertson 23 Dec '22

23 Dec '22

Does anyone know Tim Matthews (in the UK) and can ask him if he is aware his web site arcadetech.org is down? He is hosting the TTL library (I have a complete archive of course) and I noticed it was down when I tried to upload some files yesterday. I sent him an email but did not hear back. The domain is listed as active until 2020 so it must be a server thing... Thanks!

ADDR ERROR @ XXXXh - LOOP?
by John Robertson 24 Mar '21

24 Mar '21

And here is a new one for me, don't recall seeing that error message before, nor can I find reference to it in the 9010A Operator Manual. Pressing the MORE key gives me "ADDR BITS 0100 - LOOP?" so I assumed this was some sort of a decode issue and will proceed accordingly. Just thought I would post it here in case anyone else runs across this rare error message which I assume was added to the 3A ROMs in the 9010, but not to the manual - at least the copy I have... (later) It was indeed a problem with some address lines. For only A7 and A8 when loop reading @ 0000 (easiest - all should be Low) with the 9010 probe (set to Address) the Low light was flickering, not steady Low. Turned out to be a 74LS367 that had two inputs that were somehow pulling the lines slightly high. This did not show up when doing a ROM or BUSS test - only in either of the RAM tests.

searching for Fluke TK80A Rev C schematic and Fluke TestWriter software
by Gonzalo Fernandez 29 Feb '20

29 Feb '20

Hello: I´m searching for the schematic of the Fluke TK80 trainer board: I have the Fluke TK80A Rev C trainer board, this board has a foil keypad (has no keyboard keys), but all the documentation in the ftp site is for the first release of Fluke TK80 board (keyboard with keys), someone has the schematic of the TK80A Rev C board I have? The Fluke TK80A board is based on 8080 processor and is a trainer board to be used in conjunction with the Fluke 9010A tester. Also I´m searching for the Fluke TestWriter software (option 9020A-925) This software enables you to use the PC as a datalogger, controller,..with the Fluke 9010A attached to the PC serial port (if the Fluke 9010A has the GF option installed) I have searched the ftp site but no luck. I have been able to find the utilities program tape programs, such programs are posted (side A and side B of tape) in ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9010%20Series/9010A%20Tap… 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/

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!

I just added sortable columns to my KK page in the hopes you can hunt (or at least I) for the right card more easily... https://flippers.com/kurzkasc.html John :-#)# -- How to subscribe or unsubscribe from TTL http://seven.pairlist.net/mailman/listinfo/techtoolslist _______________________________________________ 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/

ADCOM PRO-2 EPROM Emulator
by John Robertson 15 Oct '19

15 Oct '19

Any one have information on these tools? I'm looking for replacement emulator for my shop (lost mine during the move in 2017 as far as I can tell) and I see these ADCOMs around. Problem is I can't find any info on them at all. Bitsavers has nothing, Archive.org, nada... So, if you have the floppy and info sheets I'd be interested! Certainly host them on TTL. Thanks, John :-#)# -- How to subscribe or unsubscribe from TTL http://seven.pairlist.net/mailman/listinfo/techtoolslist _______________________________________________ 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/

EPROM Emulator Questions
by Jess Askey 14 Oct '19

14 Oct '19

John's AdCOM question got me thinking a little bit.... So I have an old Itasca Systems NoROM Eprom emulator, it is sorta a genius little device because it is literally a small black 'Extended 32-Pin DIP' and it only sticks up about 1.5 Inches. It has a Serial Port built in with an RJ-12 (6/8Pin?) so the cable is lightweight. They stopped making it in 2000 or so and I really just want to make more of them (functionally). Some improvements would be... 1. Switch to USB + daisy chain so you can literally have dozens of these on a PCB if really needed. 2. An improved interface for sending data to the device(s) 3. Nice in place debugging and sniffing Anyone interested in working on a project like this with me? I can do the software side but Im not really there on the FPGA end. I have good details on the packaging of the ITASCA one and I can post pics if you want. They no longer make it or are in existence so I don't want to duplicate it per se, just build something with core functionality in the same form factor. Email me if interested.... jess(a)askey.org _______________________________________________ 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/

Tek 1240/1241 Mainframe Card Compatability?
by Brad Gass 03 Oct '19

03 Oct '19

Hoping there might be a Tek guru out there that can answer this off the top of their head... Are the basic mainframe modules/boards compatible between the 1241 and 1240 (excluding the video card, obviously)? I can't find my paper service manuals right off to research, and PDF manuals are a pain to skim for me anyway. I have a bad "Control Processor" board in my 1241 (long story, yes, it's definitely toast, physically damaged) and am wondering if they are the same between the 1240 and 1241 (sans probably different firmware in the EPROM's). If they are the same, I'd just pick up a cheap locally available 1240 donor on eBay and go from there. Thanks for any insight anyone can give! --Brad _______________________________________________ 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/
