I noticed someone on rgvac posted one FA recently. I'm not planning on getting one quite yet, but was wondering how many people use this as opposed to just using the usual tools (DMM, Logic Comparator, etc). Is there a significant advantage in using this?

Help request: 16500B LA ROM images needed
by David Fish 16 Feb '07

16 Feb '07

Could someone with access to an HP 16500B Logic Analyzer do me a big favor and read the ROM images off the CPU card? The devices are AMD 27H256 PROMS in a 32-pin PLCC package. If that's not possible could you verify that all four 32-pin PLCC sockets are populated? I'd really appreciate the help. Thanks, Dave _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

HP 16510B programming info
by Adam Courchesne 15 Feb '07

15 Feb '07

I'm looking to make an app that will convert HP16510B timing info into a VCD (value change dump) format. I can get the data from the HP16500A, but I need the 16510B programming manual to know what the block data format is. Does anyone have one that can scan that section for me? Manuals are like $30+ on ebay and I can't justify that for this simple project.

Looking for 24-pin IDC flat cable plug
by Matt Rossiter 14 Feb '07

14 Feb '07

I'm trying to find a source for a 24-pin IDC flat cable plug that is .600 inch wide (like a standard eprom). Mouser has part number 151-2P24 - but it's only .300 inch wide (like a standard 74 series ttl chip). I found this part here --> http://tinyurl.com/3aqqy6 - but I don't think I can order directly from this company. I sent them an email though. Anyway, I want to build a connector that allows me to separate the Sega XY timing and control boards far apart, but I seem to be having a hard time locating this plug. http://games.rossiters.com/24p-connector.jpg Just wondering if anyone knows a good source. Matt PS - Action Electronics is a good source if you want to make your own Cinematronics connectors. http://www.action-electronics.com/computerconnectors.htm _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Manual for the Fluke Z80 pod...
by Chris Hardy 13 Feb '07

13 Feb '07

I was curious about the physical differences between the Z80 and the Z80QT pod but there only seems to be a scan of the Z80QT manual. (would be nice to convert a std z80 pod to a qt one) Does anyone have a scan of the standard Z80 manual? I've looked in my old spies TE archive and it's not there or on the TTL ftp Thanks Chris Hardy _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Re: [Techtoolslist] O-scope Z-Channel Question
by Dave M 11 Feb '07

11 Feb '07

Taken from the 475 manual, the Z-Axis has the following characteristics: Sensitivity: Positive-going signal from ground decreases intensity 5 V P-P signal causes noticeable modulation at normal intensity Maximum Input Voltage: 100 V (DC plus peak AC) 100 V P-P AC at 1 kHz or less Useable Frequency Range: DC to 50 MHz. I take the sensitivity spec to mean that you need AT LEAST 5Vp-p to see any intensity modulation. To completely blank the trace, you need more than 5Vp-p. I haven't used the Z-Axis on my 575 in recent memory, but it makes sense that you will need to (A) check the amplitude and polarity of the signal you're feeding to the Z-Axis, (B) amplify it to an amplitude that will give you the needed blanking level, and (C) invert it if necessary to give a positive-going pulse with ground reference. Getting sufficient amplitude to completely blank the trace will likely require some experimentation, but shouldn't be difficult. If I were doing this, I'd start with an amplifier with a gain of 2x to maybe 5x and see how that works. My guess is that it will take a pulse of around +10V to give complete blanking. Cheers!!

O-scope Z-Channel Question
by Matt Rossiter 10 Feb '07

10 Feb '07

I'm using a Tektronix 475 Oscilloscope and, of course, I use XY mode for testing to see if the X and Y signals look good on the screen. There is an external Z axis channel in the back, but I've never gotten it completely to work. Someone once told me that I need to use an inverter to invert the signal into the probe - which sort of works, but I still see the vector retrace lines. Is it possible to completely blank out the Z signals so that the picture looks the way it's supposed to? Thanks Matt _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

9100 TL/1 reference manual
by andy 27 Jan '07

27 Jan '07

hi all.. well, after getting my 9100 all running for programming i find myself scratching around for the TL/1 reference manual, i can't find it on flippers, but i hear reference in the ttl archives that James Bright did scan it in 2003.... or am i just being blind? TL/1 is a quirky godamn language thats for sure :) Andy ps - i will be updating my page with how to run the video output to a regular low-res arcade monitor when i get 5 mins. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
