BK makes some, I have the 550. But not cheap, about $300. The one to look for IMHO is an ICT 101. Most if you didn't know require a good chip in the same family (LS, S, HC, etc.) to compare it to for best results. The ICT has a library so it knows what the chip is supposed to do. Very hard to find though. It is my opinion that they will 'lie' to you, and you also have to know when they are telling the truth. For instance if a pin is tied low by accident on the PCB, and the same pin of the chip in the comparator goes high, it will show as a fault. But it is because the two chips aren't tied directly together. So, really the chip in the PCB is good, but you have a problem on the board itself for example a bent over pin touching ground or another pin. -----Original Message----- 1.

Yep I use one of those on the ICE2, really easy to interface using the direct Dll's provided by FTDI. FTDI has dropped the price of the module to £12 with the eeprom fitted so I'm pigsick that I spent nearly £30 on mine 2 years ago.

Yeah once the emulator's done I should be able to documment all commands types that the 9010A sends to the pods.. then with the USB adapter you could make any software you want to talk to the pods and go hogwild with features. One such app I had envisioned was one that would alow you to run custom code on a given system. Say you wanted to create your own multipac for example.. you could write it in Z80 ASM or even C for that matter, and this app would point to 3rd party compilers and assemblers specific to a given CPU and store the resulting machine code in memory. Then, instead of running the machine code from on-board ROM, it would run yours but it would execute it on the board itself. An ICE (In circuit Emulator) of sorts, which would allow you to perform on-the fly real-time firmware development. -Adam On Apr 7, 2005 7:26 AM, James Bright <james(a)quarterarcade.com> wrote: > When you get to that point, let me know.

Jump start on USB to Fluke pod adapter
by Adam Courchesne 06 Apr '05

I'm taking a graduate course in Real Time Embedded systems and for my final project, am developing a USB to Fluke POD adapter for use with my Fluke 9010A emulator. So not only do I get to tinker with what interests me but I end up getting credit for it. :-) -Adam _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

computing a checksum?
by joemagiera 05 Apr '05

05 Apr '05

Another one of my endless ideas (that I never seem to get around to actually doing). I believe I have access to a full PINMAME ROMset. I'd like to create a checksum file to incorporate into ROMIDENT. Except I don't know how to do that. Is there any easy and straightforward way to create a checksum from a ROM binary file? The only way I know is reading a ROM on my EPROM reader/burner and then having the burner compute it. (Sorry to show my ignorance on all this!). Any guidance/help much appreciated. Thanks, Joe _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Thank you John !!! Hey, you still remember... I'm fighting with Visual Basic to write one software to control te LPT1 port... I'm trying to write one code in VB to run only on win98 machines, because Microsoft decide to complicate the LPT1 access on XP... Any help will be very wellcome !

No, LS is what's used all over the Pac board and it's what was there. I don't think it uses any other family. I did buy some new sync buss cards that the guy used HC/HCT ships which is neat. The game worked slightly better with those chips but as that isn't the proble, rather the inputs to the sync buss card, that's where I'll focus. I hesitate to do 'non standard' mods, because the next guy down the line may not know what it's for. -------- You didn't use the wrong family by any chance? 74C has the worst output _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

No, new chip. Replaced a lot of the chips in the timeing circuit and socketed them with double wipe sockets. -----Original Message----- The legs of the chip in question aren't rusty by any chance are they?
