Hi! What do you guys could tell about the BK 560 ic tester? Is it a good in-circuit ic tester? I have one ICT-101 and i have mixed feelings about it. Thanks JL _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

I never do component level work in the field other than Williams ram. -----Original Message----- From: "John Robertson" <jrr(a)flippers.com> Sent: ‎6/‎12/‎2013 4:46 PM To: "techtoolslist(a)flippers.com" <techtoolslist(a)flippers.com> Subject: Re: [Techtoolslist] Interesting stuff on eBay...

Don't think my manual had schematics. I never saw any schematics for this device, other than what I made up to convert another one I had to Z80. These can work well as long as the board designer followed the Z80 manufacturers specs and used pull-up resistors on Bus Request and a few others. There are at least four CPUs covered in the series, Z80, 8085, 6809 and another...and it is interesting to watch the device in action, testing RAM while the game is running in attract mode is quite amusing! However I must confess these all sit on the shelf as giant dust bunnies as I use the 9010 instead on the few game boards I still service. However for field work they would be great, so (quick poll) how many of us fix 8-bit CPU based devices in the field??

HP 1980b replacement thyristor...
by Andrew Welburn 04 Jun '13

04 Jun '13

hi all.. I have a HP 1980b oscilloscope that has a shorted thyristor, marked 1884-0217.. after looking online and getting two quotes for a replacement ($777.77 and $600 each!) i decided to hunt a replacement. I managed to pick up a service manual for this thing, and helpfully HP lists the 1884-0217 with a manufacturer number of MAC10-2 I can't find any of those either just yet, but wondered if a replacement MAC10-3 might be ok as i can get one of those.. http://www.datasheetarchive.com/MAC10-2-datasheet.html The MAC10-2 has a maximum repetitve peak voltage of 50v, the MAC10-3 is 100v... Its used in the LVPS (pcb A1 refdes A1Q2), would having a higher maximum repetitve peak voltage cause problems when replacing a Triac/Thyristor? any advice appreciated! -- Andrew Welburn http://www.andys-arcade.com _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
