100uF 20V Wet Tantalum Substitute?
by Bill Karkula 28 Apr '09

28 Apr '09

I acquired an HP1740A scope and all is well except this one capacitor described as 100uF 20V +/- 10% wet tantalum which has leaked and the electrolyte crystallized located on the timebase board. Do I need to replace it exactly or is there a newer type of capacitor that can be used as a substitute with better than or equal to characteristics of a wet tantalum? I looked around and the wet tantalums are very pricey. I know capacitor technology has come a long way and maybe someone can help save me the research.

Repairing Fluke 9010a Tape Decks
by Matthew Rossiter 23 Apr '09

23 Apr '09

Has anyone ever seriously gone through and tried repairing these? There seems to be two main problems. 1) The Playwheel gets dented as a result of being pressed next to the capstan for years. Thanks to Art Mallet, I was able to get one replacement playwheel. I'm trying to figure out if there's a way to replace the rubber ring since replacement playwheels are no longer available. I might try some O-rings from here http://www.mcmaster.com/#as568a-o-rings/=1koq0o unless someone knows a tape cassette specialist that carries something similar to the Fluke 9010a Tape deck. Question: Has anyone ever tried a workaround for the bad playwheel problem? 2) The second problem seems to be the LED / Phototransistor sensor pair that signals the end of tape (Clear Leader). In both tape decks I have, I've had to replace the 2n3906 transistor at Q5 that turns the Clear Leader signal on and off. I've replaced the phototransistor and the IR LED, but it still isn't signalling the end of tape properly. Question: Has anyone ever replaced the LED and Phototransistor and gotten it to work? I know they need to be matched. What part numbers did you get? I have a bunch of video game related tapes I want to record to a file and share. Thanks! Matt PS. Here is a condensed version of the Fluke 9010a Service manual that deals primarily with the Tape Deck. http://games.rossiters.com/manuals/fluke/Fluke-9010a-Tape-Deck.pdf _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Building a Fluke 9010A RAM test for 5101s
by John Robertson 17 Apr '09

17 Apr '09

Random ramblings... Has anyone created a test for these CMOS RAMs? I am not very good at programming and it would be useful to have this. The only other way I can think to make a valid test is to make an adapter that holds a second 5101 that fits onthe5101 under test and run all the lines except the data in parallel - have a jumper that takes the extra 4 data lines over to a Eprom/ROM using a glomper clip. However a proper software test would be more elegant...yet the glomper easier to make up! If I can find a 22 pin version that is, or simply bend out the data lines and wedge the5101 onto the one on the board...hmm, that does sound easier, then one can use the built-in Fluke RAM test. I'll let you know if the glomper test gizmo works - have a couple of irritating Williams boards to try this on.

Fluke 9010a and Sega G80 boards
by Matt Rossiter 16 Apr '09

16 Apr '09

Has anyone tried reading ROM signatures on the Sega G80 boardsets using the Fluke 9010a? I'm getting inconsistent signatures each time I tried to read each rom. I'm able to successfully read/write to the CPU and Vector Rams though. The boards all work fine with a normal Z80 processor installed, but I can't run the game with a Z-80 pod connected to it. Just wondering if anyone else has had the same problem.

PAT-9001 (UK version Pat-9000), seeking info
by electronicamuse＠aol.com 17 Mar '09

17 Mar '09

I think that I have one of these units, but no labels anywhere. I read an old RGVAC posting that somebody in the UK found some and they were reported to be like a boiled-down version of the PAT-9000. I'd love to get any info on it. It's not quite like the PAT-9000, so I am not sure how to hook up a vector monitor. Included in my purchase is some spare ITT Cannon housings, etc. I might be up for some trades. thanks Dave _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/
