RS232 and the Tek 1240
by Adam Courchesne 16 Jan '07

16 Jan '07

Playing around with my Tek 1240 and it's RS232 module for the first time. Anyonw know how to dump data from this thing? If I connect it to a terminal and hit "Request Acqmem upload" I can see "Status C0" on the PC but that's it. The Tek also says "No carrier" on the upper right. Anyone have a manual or some experience to shed some light on this? Thanks, -- -Adam =============== www.onecircuit.com =============== _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Fluke 9100 hard disk write errors
by andy 15 Jan '07

15 Jan '07

hi all... again. Well, i've hit another brick wall in my 9100 upgrade and was wondering if anyone else has come across this before. Basically, the 9100 is refusing to write to the hard disk... i'm getting 'write error' every time i try either to copy DR1 to HDR, or even saving a calibration/settings file to HDR... the story so far: It all went wrong when i booted my 9100 from system 6.0 floppies, and copied all three system disks DR1 to HDR... when rebooted, the 9100 failed to load, throwing up a mixture of Error loading OS F7, or OS F4, and then proceeding with ERROR 244 or ERROR 205 and prompting to continue through a mire of root software errors. end result, the machine hung after the last error 'application exited abnormally internal error 102' - if anyone wants a full list of error codes, let me know... So, someone suggested formatting the hard disk, booting from floppies, and copying them over again... so i duly booted from the service disk, and formatted the drive, choosing option 5 - no dma. two options, 4 dma, 5 no dma... wasn't sure what to pick and couldn't find any info in the manuals about this. picked 5, and formatted. After doing a physical format / verification, results were : 74 bad (sectors) - 19.13mb available. I booted the v6.0 floppies and went to copy DR1 to HDR, and immediately got a write error.... So i got bored and I upgraded the roms in my machine (from 27256 V3.0 to 27c512 V5.0) thinking it might help, can't make the problem worse i thought :) I then retried the process again and it still failed.. So i checked if this was a system disk copying problem, or a general hard disk writing problem, i went into 'setup | save system settings in userdisk' and got the very same write error, indicating it must be a global hdisk writing error, not a problem with just the disk copying section. So then i booted to the service disk, and formatted the hard disk once again, but this time took option 4 - dma... same as above, booted in from floppies and i still get the write error. I have the western digital interface and the miniscribe 8254 drive, cannon floppy, and 2mb ram, i have set the config options correctly from the service disk utility, and tried numerous times copying to hard disk, with this write error all the time now.. i even made up a set of old 4.1(b) system disks (this was what my system had on it before) and tried the same things, and still this write error.. I turned on the disk error reporting from the service disk, and when i get the write error now, it shows the address as 00000001 so its the very first write it is failing on each time.. Bearing in mind the drive still appears to format ok, and that i had no previous problems with it, do you think this write error is the drive, or the controller, or the software mis reporting it? any help appreciated, or i'm going to be reduced to manually loading the system software from floppy disks everytime i want to use the damn thing, which will be a real pain as i do use the 9100 almost on a daily basis. ta, Andy. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Fluke 9100 signature analysis?
by andy 14 Jan '07

14 Jan '07

hi all. has anyone come up with a scheme for using the 9100 for standalone signature analysis? ie using a NOP adapter in the cpu socket, and using the probe to read node signatures from the display in UFI mode? I have managed to take stable signatures from a few nodes, but i can't guarantee the accuracy or extent of the test.. This was on a missile commnad, i'm using theta 2 as clk, start is on A15.. [sync probe to ext enable always clock | start | stop count 1000] (clock down arrow, start down arrow) then, place probe on node under test, and hit [probe arm], then [probe show] So basically it generates a CRC from 1000 samples after the falling start edge, which i suppose is a clunky way of sampling a repeating pattern (a nop adapter). But is this really a reliable way of taking signatures? i havn't managed to get the start/stop rising/falling edge combination right to get stable signatures any other way, am i missing something, and what start/stop scheme do you guys use? (if any!) interested to hear back from you..

Fluke 9100 pod recognition after software install
by andy 11 Jan '07

11 Jan '07

hi all. Well, thanks to list members (Al, Corey - thanks!) i got the bits i needed to get my 9100 hard disk replaced... i can now use it again for the most part.. as previously threatened, i have made a page up of the ordeal involved in the hopes it will probably save someone else a whole bunch of time :) http://www.andysarcade.net/personal/tech/fluke9100/index.htm I am however stuck on one fairly major problem... i can't get the 9100 to see my 8080 pod, and i think it stems from not being able to copy master/user disk 1 over.... so here's some background Firstly the 6502 pod wasn't recognised when the system was reset, so i copied master/user disk 2 from dr1 to hdr and then it works fine.... disk 1 would not copy over, but becasue it was working for now i didn't disturb it.... until i went to use my 8080 pod and i get the following error: 'pod name does not match data base name.' (same as the 6502 pod error before) So i set about making new master/user disk 1, thinking it was a disk or transfer error. The fluke error that fails while copying is 'File not accessible' which doesn't sound like a floppy error, but i thought i'd have to give it a go... 5 disks later still no change... So i thought of trying the master/user disks from the v4.1 distribution... same error copying disk 1 again... hmm I decided to install system 4.1 and copy the 4.1 user disks over again and see if the problem was the same... and it at least confirmed what i thought, its not actually a floppy fault, its something on the hard disk. The error this time is reported differently by the 4.1 system software as : 'INTERNAL ERROR 5243: Trying to copy a file over a directory'. So that does at least give a bit more of an idea of what is going on, and that its not a floppy issue, but maybe a pre-existing directory on the hard disk that the disk is trying to copy on top of, and failing... I don't really want to, but it might be worth formatting the hard disk (again) and installing system 6.0 afresh.... Before, i formatted the hard disk, installed v6.0 system software, then copied the programmer disk over, and now i'm trying to copy the master/user disks over... is it feasable that the programmer disk might create a directory that the master/user disk also wants to create and fails becasue its too damn stupid to handle it? i'm thinking it could maybe be a disk installation sequence issue.. any ideas from anyone? thanks Andy _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

What IC is this? what does it do?
by Joseph Magiera 04 Jan '07

04 Jan '07

I know this is a tech-tools list, but I'm hoping someone here can identify a chip for me. 18 pin, NMOS8342-A MS2620F-15 The "6" in the second line could be a "G" I guess, but I really think it's a 6. But it could be MS2G20F-15. I'm guessing the 8342 is the year and week code, but I can't find anything on 2620 (or 2G20). I'm guessing some type of RAM, but that's totally a guess. Also, in rotated text, to the left and perpendicular to the text above, in capital block letters is AEZ. It sure appears this is a manufacturers symbol or abbreviation, but I can't find anything on that either. Anyone have any ideas or clues?

booting 9100 from floppies
by Mark Hooks 28 Dec '06

"just hold down SOFTKEY-F2-F4 " Just to remind those trying this, you must first upgrade the ROMs on the PCB before that command works. I tried it with version 2 ROMs and it wouldn't recognize that series of keystrokes. ------------------------------ Message: 5 Date: Thu, 28 Dec 2006 11:21:05 -0500 From: Corey Stup <Corey(a)Stup.net> Subject: Re: [Techtoolslist] booting 9100 from floppies To: Technical Tools Mail List <techtoolslist(a)flippers.com> Message-ID: <4593EEF1.1080604(a)Stup.net> Content-Type: text/plain; charset=ISO-8859-1; format=flowed > of course, i havn't got even to that stage yet because i can't get my 9100 > to boot from floppy, i had assumed putting the disk in and switching on it > should find the disk and try to run off that, but no luck for me trying > that... > > any thoughts? > Make a set ofthe 6.0 images. The 6.1's can't be trusted. I have a set of 6.1 data, and honestly its minimally different from 6.0. Somewhere I have notes that show which binaries/libraries have any differences at all. Anyway, to boot from floppy, just hold down SOFTKEY-F2-F4 while booting. It will skip the HD and attempt to load from floppy. ------------------------------ _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

booting 9100 from floppies
by andy 28 Dec '06

28 Dec '06

hi all. Well I spent most of yesterday and this morning finding a way to make floppy disk images using Teledisk, boy was that a painful process..... (3 versions of teledisk later, and using a 486dx4-75 laptop to get it working..) so now i have some disks made up, i want to get my 9100 to boot them.. but can i heck. Late last night i'm sure i saw a pdf that had a software install procedure, but i can't for the life of me find it now, i have looked on flippers again for it, but can't find it, forest for the trees... can anyone let us know how to make the 9100 boot from floppy, or remind me of the pdf file that i saw so i can just get on with it myself? this is driving me crackers... ultimately i am going to try to upgrade my system software from 4.1 to 6.0 (i searched TTL and found that the 6.1 disk images are bad - john can you mark these as bad in the ftp? i wasted quite a bit of time before finding this out heh) and also upgrade the feeble 2mb ram to 4mb or whatever i can get to work... i also need to get the videocard that i have installed to work too.... but first things first i want to get the software upgraded.... thanks!
