Updating - W-G 6100 Vector Monitor FAQ & Guide V1.1
by John Robertson via Techtoolslist 06 Dec '23

06 Dec '23

Who is maintaining this? I ask because on page 8 there is a typo - that I've only just realized when I was going through trying to update my WG monitors as we have a pair of SWs that are running WGs (with the LV2000 kits). It says "R701 (1.3K) changed from +/-2%, 1/4W to +/-1%, *5*W.(*)" That can't be right, I am certain it should instead say: "R701 (1.3K) changed from +/-2%, 1/4W to +/-1%, *_0._5*W.(*)" and it would be clearer with: "R701 (1.3K) changed from +/-2%, 1/4W to +/-1%, _*1/2*_W.(*)" It makes no sense otherwise. There simply can't be enough current for a 5W resistor as this is ground biasing the base of a small signal transistor. Then there is the question of Q604/Q704 (MPSU07) transistors upgraded to TO-202 (NTE-49) which looks like another problem as there is no NTE-49 and hasn't been for decades. That was the same as the ECG-49, which was a NPN-Si, 125Vcbo, 2A, Gen Purpose TO-202. Anyone have a workable replacement to save me the lookup time? I'm thinking a Rv1.2 is overdue...

email forwarding and Gmail
by John Robertson via Techtoolslist 05 Dec '23

05 Dec '23

Hi Folks, I've had some bounces lately and Pair Tech Support has figured it out: ---------(quote)----------- The Yahoo IPs are getting in the headers and bounce messages due to forwards. The headers you provided show this line: X-Yahoo-Forwarded: From somebody(a)verizon.net To someboy(a)gmail.com Verizon sub-contracts Yahoo to host their @verizon.net. It seems that you havesomebody(a)verizon.net on your PairList mailing list, and the user of that address has it set to forward to his Gmail address. Gmail is rejecting the forward from the Yahoo server due to your DMARC setup and the SPF record you have in place. There is no way to force Gmail to accept the forwarded mail, and no way to force Yahoo to do a better job forwarding mail. The only real solution is to replace thesomebody(a)verizon.net address on your PairList with that person's real e-mail address, which appears to besomebody(a)gmail.com. Doing this would prevent it from being forwarded through Yahoo services. I suspect you will over time get similar bounces from others who forward through Yahoo as well. In each case you would need to read through the bounce message and see which address it was sent to (which will be the address that is forwarding the mail), and which address is listed as the address it bounced from (which is where the mail was being forwarded to), then update your mailing list accordingly. ---------(end tech quote)---------- So, if you are forwarding emails then gmail has a surprise in store for you!

They are different, and mostly everyone uses the crc32 script on the 9100. I don't think anybody EVER figured out the Fluke 9100 signature math.

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.

Noise…
by John Robertson via Techtoolslist 09 Oct '23

09 Oct '23

I was trying to sort out a Rottendog System 9TO11 MPU that would work with some EPROMs - sometimes - but not others. So pulled out the 9010 and 6802 pod and did some signatures. Sure enough the signatures were not the same ones twice. Made a simple RAM test for verifying the Data and lower Address lines at the EPROM positions - used a 6265 RAM and tied the /WE line to pin 27 of the CMOS RAM (R/W). And the 9010 RAM tests worked just fine so I was sure the Data lines and lower Address lines (A0-A12) were good. Scope on A13 and A14 were inconclusive. Pulled out my 6802 NOP CPU (hard wired to NOP) and scoped A13 - lots of noise on the bottom half of the cycle! Replaced the 74HCT244 buffer and the board is again a happy camper! I do like my NOPs for checking Address lines! I made them years ago for the common 8-bit CPUs and use them periodically on weird problems that the Fluke 9010 can’t nail down. Just bend the CPU’s Data leads up and tie them as needed to produce the NOP code.

Data I/O Unisite - Issues
by Steve Larkins 24 Jul '23

24 Jul '23

Hey all I am hoping someone can help me with my Dat I/O Unisite. I have had this for a really long time but got it on the bench a month or so back to use it and it would not pass the self test. I ended up getting a fatal error reported on the com port via telnet and based on someone else's suggestion I tried replacing the floppy controller. This worked and got the system to the point where it reported a boot disk fail. I used a gotek with flash floppy and copied over a boot disk which then allowed me to get the system to boot but with a mass storage unit failure. I replace the original PCMCIA hard drive with a PCMCIA Flash adapter (Added a jumper to the adapter to allow it to work) and got it to pass a self test. I am now trying to transfer the system software via the \configure system\Mass Storage\Install new version of software and it fails at Algorithm set 3 disk. I have successfully transferred the 9.4 software disk, alg#1 disk, alg#2 disk but when it prompts me for alg#3 disk it tries to read from drive 0 rather than drive 1 like it did for the other alg disks. I have tried to switch disk 0 to alg#3 but it stops responding to the "enter" on the terminal and I have to press "^Z" to abort which it does. Even after this process off transferring the system software I cannot boot from the mass storage unit and it asks for a valid boot disk. Has the installation not completed caused this? Can anyone help?

Williams System 7 test ROM

I have an original Williams System 3-7 test rig, but I only have the original ROM image, that deals with System 3-6 (fits on a 2516). Can anyone point me at a copy of the later 2532 image that includes the System 7 tests?

FS: NOS Fluke 9100A/AF manual set
by Justin 28 Jun '23

28 Jun '23

Hi - I snagged this set a few years ago and never ended up using it. There’s also a NOS test / diags board as well. Some of the manuals have some minor wear from being shipped (creases on edge and scuffs), but nothing major. Asking $265 shipped unless you can do local pickup in Tacoma, WA.
