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

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.

Fluke demo trainer
by Marc Desfossés 12 Aug '20

Hi, Has anyone in this group ever tried the Fluke 9000a-010 demo trainer unit ? It seems like a good way to learn the 9100 functionalities. I'd be curious to get your feedback. Thanks !

Fluke 9100ft + Keyboard + Monitor + Probe + Vector I/O Module
by Steve Larkins 07 Aug '20

Hey list I hope you are all well. I thought I would offer this up on here before I put it online. What I could do with is a valuation on this bundle and see if there is any interest. I am in the UK but I can box this up into 3 parcels and ship internationally if needed. 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/

Gotek w/ FlashFloppy and github service disk problems
by Tim Matthews 22 Jul '20

22 Jul '20

Hi all, I am trying to resurrect a 9100 with dead HD and switch it to SCSI-CF. I have no way of creating a real system floppy so have installed a gotek, flashed it to FlashFloppy 2.14. Using info from Porchy's site and Tony Jones' post to this list, I've got an FF.CFG set to shugart, jumper on D0 and nowhere else. I took the kryo stream from 9100A-USAF/SERVICE-V1.4 and using HxCFloppyemulator tool imported the stream and re-exported as both hfe and img. With both of those files on USB booting softkeys+F2+F4 gets the 9100 trying to boot, but it fails. The gotek shows cylinder reads 0-3, lower side only, for less than a second. Switching the gotek to the second image and rebooting the 9100 has the same result. I installed the logging gotek FW and can show the gotek is seeing/mounting the images and serving (log excerpt below [0]). I have also tried an FF.CFG with host set to fluke, but the results are identical. I've hooked the gotek to a PC and used it to boot dos floppy images so I know the device, fw and cabling is good (had a different FF.CFG for the pc, but only the interface value). My converted image details are: service.hfe: 2,213,376 bytes sha1 f9c6dbf07ab84b3cecaa52a2563b315ffe338beb service.img 655,360 bytes sha1 0dca7b164fcfadfd5cf7eb9be99888318b510408 I am pretty certain the hardware setup is ok, so I think the issue is with the images. If anybody has an hfe or img of the service disk they can point me to I would be incredibly appreciative :D All advice is very welcome! thanks, [0] flashfloppy log excerpt Name: 'service-stream' Type: hfe Attr: 20 Clus: 000000be Size: 2213376 Fast Seek: 1 frags Cache 29 items Cache 105 items Before: After: Current slot: 1/1 Name: 'service-stream' Type: img Attr: 20 Clus: 0000032a Size: 655360 Fast Seek: 1 frags Cache 34 items Cache 105 items _______________________________________________ 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/

Parting out lot of Tektronix scopes 7704 vintage
by Art 16 Jul '20

16 Jul '20

First let me apologize for this likely being in the wrong place or otherwise somehow mis-posted. Those who remember me from the arcade game newsgroups may well remember that I never had a very good grip on posting procedures and protocols. That said - I acquired 2 Tek 7704s, a 7834, 7704A, a pair of the 3 slot versions of the 7704, model number escapes me at the moment, 7623, 7633, and a 5103. At the moment none of them work properly. The 7704A and the 7834 both worked properly until I used them to test a batch of plugins and each was damaged by bad 7A26 vertical amps. I checked the power supplies on both and they are ok. I don't have the understanding of scope operating theory, the patience, and most of all, the desire, to fix these. In addition I do not wish to ship working scopes of that weight and bulk; getting to be an old fart now and don't want to haul a packed 45 pound scope up my cellar stairs to the porch for UPS. So - all but one of the 7704s worked to the extent of being able to verify that HV was present and the CRT had usable brightness; most had either vertical or horizontal deflection. The 7834 was working, the storage buttons produced various changes in the phosphor. All I believe have decent complete knob sets except for one of the 7704s. Holler if you need anything and we can work something out on price. If you are willing to pay the extra shipping I will sell the 7704s if I can ship them in 2 pieces, separating the display from the acquisition unit. Hope this finds you all safe and healthy - stay that way :) Art - From NY _______________________________________________ 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/
