Assman "Ribbon Cable Tester"
Anyone else playing with one of these? It is a ribbon cable tester I found on eBay and you teach it for each cable being tested. It only remembers the current cable under test. Inside it says "Ribbon B2 Hobbes CO." on the main PCB. Doesn't appear to be any town called Hobbes in Colorado...(Calvin & Hobbes pops up of course) This device runs off 9VDC wall wart or has a battery which you can also run it off. My unit drains the battery rather quickly when off and the wall wart is not plugged in. The 9V battery is not used to retain memory, that function is covered with a HM6265WH-70 CMOS RAM which is maintained by a 10Ufd cap that is charged by a diode to the 5VDC buss. That size cap drained from 4.8VDC to 2.6VDC overnight. If you want to store longer, then use a bigger cap. The annoying thing about this tester is the 9V battery drainage means there is always a LOW BATTERY warning on the display. So I have to sketch out the 9V battery circuit and figure out why there are so many jumpers installed from the factory for that battery. I have uploaded manual and photos of the outside and inside of the gizmo in case you are curious to: ftp://ttl.arcadetech.org/TTL/Test_Equipment/Assman We are producing ribbon cables for arcade games and it will be nice to have this working correctly.

Im trying to figure out where the 'Assman' prefix came from? I was expecting some sort of Seinfeld reference. 😊 -----Original Message----- From: Techtoolslist [mailto:techtoolslist-bounces@flippers.com] On Behalf Of John Robertson Sent: Thursday, November 16, 2017 1:08 PM To: techtoolslist@flippers.com Subject: [Techtoolslist] Assman "Ribbon Cable Tester" Anyone else playing with one of these?

Assman WSW Components used to sell these devices: https://www.digikey.ca/product-detail/en/assmann-wsw-components/ACT-PC-SO/AE... No longer supported (I asked). They have no info on outdated tools. The CPU is a Toshiba TMP47P400VN whatever that is (digging). My problem appears to be with the op-amp battery level comparator, either it is defective or the various jumper wires were done incorrectly. My rough drawing caught the error with a jumpered power connection to the LM358 that accounted for the rapid 9V battery drain even when off. John :-#)# On 2017/11/16 12:49 PM, Jess Askey wrote:

The Toshiba TMP47P400VN is a CMOS CPU with onboard RAM/ROM. looks like it can be read as a 2764 with appropriate jumpers, etc. Guess I better carefully back it up soon! http://pdf1.alldatasheet.com/datasheet-pdf/view/104802/TOSHIBA/TMP47P400VN.h...

Obligatory Rodney Dangerfield quote - "People always ask me if I'm a leg man, a breast man or an ass man. I figure I must be an ass man. People yell at me all the time - YOU'RE AN ASS MAN!" As for the company name I'd bet it is a contraction of Assembly and Manufacturing. Sorry to disappoint everyone.

Sounds more like this is due to the last name of the founder (Dieter Assmann, German), not a contraction at all. https://www.assmann.com/en/about-assmann/ <https://www.assmann.com/en/about-assmann/> http://www.assmann-wsw.com/us/en/the-company/usa/ <http://www.assmann-wsw.com/us/en/the-company/usa/> David
