Fluke 9020A troubleshooter - swapping ieee488 i/f for rs232 i/f
by andysmout＠bigpond.com 23 Mar '15

23 Mar '15

hello all! i just acquired a Fluke 9020A troubleshooter with option 002 ieee488 interface at a good price, and i have an operators manual and service manual on the way. does anyone know if i need to change roms if i swap the gpib interface for an rs232 interface ?

Speaking of Leland Off Road.. Do these actually suicide?

I'll look for it Tuesday and report back here... I can take a few pictures of it. (I might even have a Track Pack boardset and could just read the PROM in here. I don't remember what's our machine in storage. I'll look. If nothing else, if our PCB is the original one just reading and duplicating that would serve as a proof of concept.) OE&CE can just be disconnected. Looking at the schematics all the outputs are going to be push/pull (no tristate), so nothing 'special' required to brute-force the dump.

Re: [Techtoolslist] Fluke 9020a - need replacement "low pulse" key switch
by Brent Walker 17 Mar '15

17 Mar '15

Andy, I had a similar issue on a 9010a I picked up several months ago - the key would stick down and not want to come back up, or wouldn’t lock down at all. I unsoldered the switch from the keyboard, at which point it’s not too hard work on. I suspect the little wire piece that flips back and forth got bent, and you’ll need to gently get it bent back into position - not necessarily an easy task. You may need some light lubrication in it as well (I used a bit of silicon spray). If you’re handy with that type of thing, it can definitely be done; I spent about 30 to 45 minutes tweaking mine until I was happy with it. It clicks back and forth consistently about 90% of the time, which was good enough for me, and much better than it was. Either way, these switches aren’t too common, so fixing it is your best shot I suspect - good luck!

9020A via IEEE-488?
by Nigel Williams 17 Mar '15

17 Mar '15

I recently acquired a 9020A with a IEEE-488 interface and wondering if anyone has documents for using this configuration. I found the 9010A vs 9020A differences document from Fluke, but I'm not sure what software was used to control the 9020A via the 488 bus. I would be interested in the service manual and operating manual for the 9020A if anyone has spares too please. 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/

Changing mains voltage for power supply PSU on the Fluke 9020A
by Nigel Williams 17 Mar '15

17 Mar '15

In the interest of saving someone else a little time, if you need to change the line-voltage on the Fluke 9020A micro-tester then refer to the following pictures: http://imgur.com/a/Im6bF#0 In the final picture are two slide switches in the lower middle, on the PCB there is an indication of the voltage options and you can adjust the switches, for 240V I swapped them from how they appear in the picture (which was how they were set for 110V). Safety-first, don't try this at home without supervision etc unless you know what you're doing. _______________________________________________ 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/

Do you have a pinout of how you did it Did you go from pin one to pin one Did it matter what address line or data line went to what pin on eprom The 2716 starts at address 7 on pin 1 And data lines are split >From side to side What did you do with /oe or /ce Thanks tony -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of Clay Cowgill Sent: Monday, March 16, 2015 4:20 PM To: 'Technical Tools Mail List' Subject: Re: [Techtoolslist] leland off road pal dump needed u85 Since it's an 16L8 (and not an 'R' or 'V') you don't have to worry about any hidden internal states. Back around ~2003, Tim Lindquist and I reverse engineered the Capcom CPS2 B board PALs. I made a little wiring adapter for the 16L8 to be read as a 2716 EPROM. (Connect all the inputs to the 'address' lines and the outputs to the 'data' lines.) Reading the "2716" produced a binary file of all the possible input/output combinations. I extracted that as text and formatted it in to ABEL table format like: PAL CONVERTER ; Converting: cap_caw.bin... [ 0,0,0,0,0,0,0,0,0,0,0,0,0,0 ] -> [ 0,1,0,1 ]; [ 1,0,0,0,0,0,0,0,0,0,0,0,0,0 ] -> [ 0,1,0,1 ]; [ 0,1,0,0,0,0,0,0,0,0,0,0,0,0 ] -> [ 0,1,0,1 ]; [ 1,1,0,0,0,0,0,0,0,0,0,0,0,0 ] -> [ 0,1,0,1 ]; ...

A pretty much automatic process that didn't really require any special 'pal cracking' capable hardware. The ABEL compiler also produced the intermediate equations which were much more compact than the big tables-- for example, ~2000 lines of the above stuff cooked down to: Y8 = (I4 & !I3 # I8 & !I4 & I10 # I4 & !I10 # !I8 & I4 # I7 # I6 # I5 # I2 # I1); Y6 = (I4 & I3 & I10 # I4 & !I3 & !I10 # I9 & I4 & I10 # !I8 & !I4 & !I10 # !I9 & !I8 & !I4 # I8 & I4 # !I7 # I6 # I5 # I2 # I1); Y4 = (I9 & I4 & !I3 # I4 & !I3 & !I10 # !I8 & I4 & I3 & I10 # !I7 & I4 & !I3 # !I7 & I4 & !I10 # I8 & I7 & I4 # I8 & !I7 & !I4 & I10 # !I8 & I7 & !I4 & !I10 # !I9 & !I8 & I7 & !I4 # I6 # I5 # I2 # I1); Y1 = (!I1); -Clay -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of Tony htbs Sent: Monday, March 16, 2015 12:23 PM To: 'Technical Tools Mail List' Subject: Re: [Techtoolslist] leland off road pal dump needed u85 U85 is the chip location I have the 2-22 u85 non track pac can you dump it if I get it to you Or can I dump it or get you a file I have several programmers I can get a 2-25 u85 trac pac but I need to get it back Where are you located Let me know thanks tony For Ivan Stewarts off road > > The track pac should be 2-25 > > And non should be the 02-22 > > Pal16l8 is the chip -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of Fabrizio Vasile Sent: Monday, March 16, 2015 2:02 PM To: Technical Tools Mail List Subject: Re: [Techtoolslist] leland off road pal dump needed u85 Hi, sadly there no available dump of these PAL around.I'm a contributor of this PAL database: www.jammarcade.net and we haven't them too.If someone could provide us the chip we would be happy to dump them P.S.
