Designing a 9010 replacement LED display?
by John Robertson via Techtoolslist 09 Feb '24

09 Feb '24

I was looking at my 9005 and grumbling because the tube is missing, then I pulled out the 9010a service manual and you know, it looks like it would be a pretty easy fix to replace the tube with 32 digit alpha-numeric LEDs of the correct size on a small PCB and all that would be needed is to replace the UDN6118 fluorescent drivers with suitable LED drivers and find a place to grab 5V and ground and then mount the new display to the board... Maybe it would work? Anyone interested in poking at the KiCAD layout? I have no free time, but I know there are folks out there looking for a solution to bad or weak tubes...

Fluke 9010 ram test for 4 bits? Or any non 8 bit wide memory?
by davids＠oz.net 04 Dec '23

04 Dec '23

Have a suspect bad pallet ram on Missile Command, and I see that it is on the CPU memory map so I should be able to get to it from the fluke. Now it is only 4 bits wide (and only uses 8 addresses) so I can just do it manually but I have seen this on other boards before and never could find a way to use the fluke to test these 4 bit rams. Would also assume it could be a problem for 68000 based boards which use 16bit wide memory.

Logic analysis and the Atari Test connector?
by davids＠oz.net 25 May '23

25 May '23

I have a missile command board which using the fluke 9010 passes all memory and rom tests perfectly. Also can exercise the pokey with no problem. But when I try to go to UUT the game just starts to make an explosionish sound and then watchdogs. Game mode and test mode. Verified the WD is working correctly. So my next thought was to connect the 16702B to the CPU address and data lines and see if I could figure out where the startup goes off the rails. Not supper excited about having to use the test clips on 16 bits of address, 8 bits of data and misc other signals. Realizing there is that nice juicy edge connector right next to the CPU I was thinking about having an adapter board made that would have and edge card and then a set of pod connectors that I could just plug the pod cables into directly. Am I reinventing the wheel here? Anyone done this and have any gotchas to mention? Or am I over thinking this and should just get a 40 pin glomper clip and attach to the top of the CPU? And connect to that?

Hp/agilent/keysight 16702b
by David Shoemaker 24 May '23

Picked one of these up on ebay for $200. Bad hard drive (scsi), have a scsi2sd adapter on the way to bring it back k to life. Mostly got it because it came with the 16522 pattern generator board. Had the full set of cables but only 1 pod, but was able to get a set of 5 more for $20 each. Have visions of doing bench testing of the mcr2 video boards completely stand alone. Move my 16550 timing / state card from my 16500b (which also had a hard drive fail).

Kurz-Kasch Logi Probe manuals...
by John Robertson via Techtoolslist 20 May '23

20 May '23

I'm looking through my files and see I am missing a few documents - never had them I'm sure. Kurz-Kasch LP-670 and LP-710 logic probes. Logic probes are still handy around our shop. If anyone has any paper on those I'd appreciate a scan and I'll upload them to TTL's FTP site. Thanks!

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/

9100 LEARN?
by John Robertson via Techtoolslist 09 May '23

09 May '23

I’ve been hunting the 9100 documents but I can’t find so far the equivalent LEARN feature as found in the 9010. It is almost as if they assumed you would have written the UUT test procedures in advance of servicing a CPU based board! I’m trying to troubleshoot a module and was hoping the Learn function would steer me to what the CPU is seeing on a development board, but can’t seem to do this with the 9100. So, time to bring a 9010 home for the weekend to get to the bottom of the addressing issues for my ALI 6530 sub-board. Something I did wrong - as the prototype worked - but the first generation PCBs aren’t yet. Anyone have a work-around for Learn on the 9100? Thanks!

Not sure I sent this correctly, apologies in advance if I have mucked it up. Do you have any 167xG acquisition cards, scope or logic generator option cards (and possibly the option backplates, etc)? Trying to find a working 1670G acquisition card for a faulty unit and the options cards to upgrade the machine.
