Fluke 9110FT SPECTRUM-TX diskettes imaged
by Martin Olsson 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...

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!

And another weird test result
by John Robertson 28 May '21

28 May '21

I don't know if you folks are interested in my headaches, but here is my latest one. Working on an Atari Superman pinball board. ROM, RAM tests are good, board boots, issue is the feature lamps flicker when turned off. However I am getting something odd on address 1800-18FFh, it displays what appears to be the last data bit in the EPROM located at 3800-3FFFh. I plugged a different EPROM in and got its last data bit too. What is odd is the EPROM, when reading 1800h shows the Address lines all as low, but there is the tiniest pulse on /CE(pin 20). I've tried stretching it out, but it appears to be the smallest resolution of my Tek 100mhz, 2230 storage scope - which I am still learning how to use. At this point I figure it is a timing issue so will dig further, but I just thought is was most curious that it didn't matter which address location 1800-18FFh was chosen, I got what appears to be the last byte in the EPROM! I have no explanation on how that can happen. I will now test that by burning a couple of 2716 with only the last byte set, will try AA and 55 and see what happens...

6502 POD and 65C02s - not playing always happily when exchanged internal CPU
by John Robertson via Techtoolslist 08 May '21

Well, I installed a 65SC02 in my 6502 pod, for a Gottlieb System 3 game I was servicing and figured that I could just leave it in my 6502 pod and then I could test either family without cracking the case open.. Not so! One game (Allied Leisure pinball MPUs) give weird errors when doing some tests with the 65SC02 CPUed pod. This pod had been happy with Gottlieb 6502 MPUs and it took me a little while to suspect the 65SC02 CPU. Replace it with the default 6502 and the ALI MPU was perfectly happy. So, just a word of warning about mucking with substitute CPUs - go back to default if odd things are happening...

Anyone done this? If so how did you control the rom banking to do rom tests? Mame driver isn't the most clear on how that works.
