Hi.

I'm repairing a couple of 68000 pods at present and it reminded me that I'd always wanted to dig deeper into this.

Does anyone have a 68000 pod running version 6 of the firmware? It's documented in rev 2 of the pod manual, and the code resides on larger 2764 EPROMs to implement the additional QT.

I've owned six 68k pods and I've never seen anything higher than rev 5.

You can get your pod version (on a 9010) by reading F0000012 (after taking the pod out of self-test of course). Output format is hex x0 where x is the major version. Not sure how to do this on a 9100 as it won't process addresses outside of what it knows as the 24bit address space, maybe TL/1.

Hmm, I’m not sure what you mean by taking the pod out of self-test. When I read that address, it selftests in a loop, and I get kicked back to the main prompt after stopping it. On my 9100, "READ SPECIAL" let me select 0xF000 0012. I haven’t opened it to verify, but assuming this is the correct procedure, it looks like I have a v6 pod: https://imgur.com/a/SADEo It has a manufacture date of January 1995. -- Ian _______________________________________________ Techtoolslist mailing list Techtoolslist@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/

I acquired a 68000 pod running V6 firmware and dumped the EPROMS. John kindly uploaded them to ftp://ftp.arcadetech.org/TTL/Test_Equipment/Fluke/9XXX%20Pods/68000pod/Fluke-9000A-68000_V6_ROM/ I was able to upgrade an another 68000 pod (rev B processor board running V5) to V6 using the data. Swapping the EPROMS (and sockets) from 2732 to 2764 is all that was required. I thought I had seen a scanned copy of the Rev B manual online (which documents the additional QT functionality in V6 -- the copy on the ftp site is Rev 1 for V2 thru V5) but I can't seem to find it. Possible I'm mis-remembering. If I find it I'll have John upload it, else I'll scan in my original copy. I hope this is useful to someone. Thanks!

I need to dig deeper into the schematics to see how this is implemented on the hw (and what the upgrade path is). The three 68000 pods I have at present, all have the pads present for the larger 28 pin sockets (on their cpu boards) but only a 24 pin socket installed. The cpu board part# and the U9 PAL part# are the same in both versions of the manual, only the EPROM part#'s differ which is curious as obviously the pin addressing differs between a 2732 and 2764.
