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.

Scope question - Tektronix 2230 & XY
by John Robertson via Techtoolslist 30 Mar '20

30 Mar '20

Anyone have a 2230 and can run a quick test for me? My unit seems to work just fine except in XY mode. I can adjust the CH2 position normally up/down, however CH1 Position control is reversed for XY and only does a small range just to the right of center. In normal mode the CH1 Position adjust works as expected. Pretty sure that result is wrong but the schematics I have are not so clear, even though they are from the Tek download files area, and hard to follow as a result. Thanks!

De Vry Instiutute Bell and Howell courses
by John Robertson via Techtoolslist 30 Mar '20

30 Mar '20

When I bought the remains of a store, Main Electronics that was a major TV parts supplier here in Canada, included were some DeVry Institute stuff, A model 34 scope and a TVTM along with various test materials - some of which I have just scanned and uploaded to the FTP site. One of these is large (29mb) as I had to redact the student's name and address for privacy reasons and I didn't get around to compressing it. What I have also uploaded are sample 1976 FCC tests, and some tests for a few of the DeVry courses and two letters. ftp://ttl.arcadetech.org/TTL/Test_Equipment_/DeVry_ If someone wants to purge the answers from the scans let me know! These were scanned with Adobe -10. I have more of these tests, but no time to scan as some are smaller format so the autofeed on my Toshiba won't work... Enjoy!

Using Fluke 9010 with ethernet / Wi-Fi (solution)
by davids＠oz.net 30 Mar '20

30 Mar '20

I have seen a few ways of doing this in the past and wanted to share the one I have been using for less than $20. I connected a HLK-RM04 serial -> Ethernet / Wi-Fi module to the fluke. Then configured it for a fixed address on ethernet. Then I run HW Virtual Serial Port software to route the com port on my desktop machine (running FIDE) to the address of the RM04. For this I use the HW VSP3 Single software. Works a treat, bi directional and over wired and wireless no dropouts or errors. More reliable than a serial cable has been for me in the past. 9600 baud, Even Parity, 1 stop, 8 data https://www.ebay.com/itm/Hi-link-HLK-RM04-Serial-Wifi-Ethernet-Wifi-Module-R S232-RS485-Module/253225173923?hash=item3af56583a3:m:mmzCM_wQDHUjy1_NCBrQFvw https://www.hw-group.com/software/hw-vsp3-virtual-serial-port This solution also works from within a Hyper-V Virtual Machine. I created one running Windows 7 32 bit to support the FIDE software. But I also verified today that running a Win 10 32 bit VM also works with FIDE and the VSP software (has to be 32 bit or the FIDE software and compilers won't work).

Sencore VA48 schematic sheets (finally!)
by John Robertson via Techtoolslist 25 Mar '20

25 Mar '20

I found I actually had an original VA48 manual hiding in one of my filing cabinets and so I just scanned the 3 large double sided schematic sheets for archive purposes and uploaded them to the FTP site under Sencore/VA48/... Enjoy! Now I can decide if I want to fix my machine...

Xeltek Universal Programmer Superpro interface?
by davids＠oz.net 24 Mar '20

24 Mar '20

Have one of these that has been on the shelf for years never figured out how to hook it up. Has a DB 25 connector on the side of it but I don't know if that is a dedicated card cable interface (IE Needhams PB10) or a parallel cable interface. Anyone know? It is similar to the one on ebay (not mine): https://www.ebay.com/itm/XELTEK-SUPERPRO-Universal-Programmer/112865734595 And if it is parallel what software supports it? I have an XP box which I should be able to run it on.

part sourcing help - edge connectors, hook leads
by Joe Magiera 23 Mar '20

23 Mar '20

Anyone have a good source for edge connectors of various sizes? I don't know what to call what I'm looking for, so it makes it hard to search for. Trying to build up my test area environment. I have a good JAMMA set up, but I'd like to expand to test non-JAMMA (and build some of the more common PCB adapters to JAMMA). I'm looking for connectors that on one side is the female side, i.e., a flat male side edge connector would plug into it. On the other side of the connector would be two rows of pins. I looked at a couple of ones that I have and while I have the female side, the two rows of pins aren't the pins I'm looking for. They just have a pin. I'd like to get pins that are flat and have a small hole in them so I can easily use hook leads. I'd also like to get an assortment of different sizes (number of pins). I hope this made sense and maybe someone can tell me the correct/proper names for these so I can search myself. And while I'm at it, anyone have a source for decent priced hook leads? The one's I've found are ridiculously expensive. $9.95 (plus shipping & tax) for a one foot piece of wire with a cheap hook on each end. Yikes. I guess I'm not very good at searching.

Hi, I am looking for the 9132A sync module and some 9132A-100 ram modules. Has someone ever tried to make a repro of the RAM modules ?
