What CPU do you have in it ? I've not found the 6809E to be that reliable, try swopping a known good CPU into the socket and make sure the dips are set for the correct type. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

GPIB
by Ness and Steve 12 Apr '07

12 Apr '07

Hello all, I have a few questions relating to PC interface cards: 1> I have an old dataman omnipro2 programmer which uses a custom ISA card. Has anyone run something like this on a P3 motherboard running at 1Ghz? - I am currently running it on a 486DX2-66 but it ill only run when I set the BIOS to run in CGA/EGA graphics mode. 2>I was wondering if anybody has any advice when looking for a suitable GPIB controller for this same PC. I intend to use it with my HP54120 18Ghz scope via Agilent VEE. I have never used VEE and never used GPIB. Many thanks Steve _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

manual for Bugtrap 8000?
by Joe Magiera 07 Apr '07

07 Apr '07

Does anyone know where an online copy of the manual for a Bugtrap Dynamic Ram Tester Model 8000 might be? Hans got it off ebay: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ih=013&sspagename=STRK%3AMEWA% 3AIT&viewitem=&item=230102520160&rd=1&rd=1 If anyone has this and be willing to scan or copy, it would be much appreciated. Looks pretty straightforward, but always nice to have a reference manual.

Re: [Techtoolslist] Huntron Tracker 200

> Not as far as I could ever tell. The only advantage was you > did not have to set up a kludge to the front of your 'scope. Kinda depends on what you're doing with it... I have a Huntron Protrack 1 and it does have some handy capabilities depending on what kind of stuff you're working with. (ie, adjustable frequency, source resistance and Clay I've used a Huntron since 1978, 1st one was #596 and find it one of the most valuable test instruments I have ever encountered. Phil Hopkins from APC.... Worked for DEC for 21 years voltage drive to get more detailed images depending on what value components are in the circuit-- plus a computer interface.) I've never really used it much as a repair tool for a single unit, but it's very handy when comparing a 'gold board' signature against multiple production units without the need to power anything on. With a computer attached you can automate things as well. (Better to find a backwards tantalum cap before even powering it up, or even worse-- incorrect parts loaded in an adjustable power supply that'll smoke a bunch of expensive actives if powered. ;-) I did use it to repair on a bunch of GO7 monitor chassis boards a couple years back. I took a 'NOS' board I had to make signatures and then just tested all the 'unknown' boards against the "known good" to find shorted transistors, bad caps, etc. without having to apply power to any of the units under test. One of the external Huntron boxes (I think the current model is the 210?) can be used with something like a Tektronix DSO that has an onscreen pass/fail mask capabilitiy. (So you can make a mask that basically says "any signal inside this boundary is a pass, anything outside is a fail" and you can have less skilled technicians still pass/fail test a board with high confidence and no PC required...) I suppose you could do the same with a paper cutout 'mask' for a less fancy o-scope too. ;-) -Clay _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

9010a Script for Pokeys
by Matt Rossiter 14 Mar '07

14 Mar '07

I wrote a test script that allows you to do audio tests on Atari Boards with Pokeys. I borrowed some ideas from other scripts. I'm not really sure what other interesting tests you can do, because I'm not really familiar with how to generated different tones on this Atari Chip, but perhaps some of you can look at my script and offer some suggestions. Right now it's pretty basic. http://games.rossiters.com/manuals/Pokey-Data-Blaster Matt _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Unipak 2B adaptor query
by Phil Morris 09 Mar '07

09 Mar '07

I have a Data I/O 29B EPROM programmer with a Unipak 2B and need to get hold of an adaptor for it, specifically adaptor no: 351B068 Does anyone either have one of these or know what it consists of please? Does it perhaps just re-route a few pins, or is there more to it than that? Thanks, Phil _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

I got a booklet and videotape a few years ago on how to build a "poor man's Huntron" using an X-Y oscilloscope, a small transformer, and a couple other odds-n-ends. I haven't built it yet to try it out. Does the Huntron do much more than what you could achieve with a simple homebrew kit? --------------------------------- Access over 1 million songs - Yahoo!
