Re: 8086 pod for fluke?

Hey, that would be my cue :) All of the M72, M82, M84 games from Irem use a NEC V20 which is a 8086 with some extra instructions. It's also pin compatible so the 8086 pod is usable with it. Of course, there aren't exactly many of these around :) Chris (M72 = RType, Dragon Breed, XMultiply, + others, M82 = RType II, Pound for Pound, M84 = Major Title) ______________________________ Reply Separator _________________________________ Subject: 8086 pod for fluke? Author: Noel Johnson <nej(a)airmail.net> at Internet Date: 1/17/00 12:09 AM Hello All, I am about to obtain an 8086 pod for a fluke 9010. Did any arcade games use the 8086 or am I going to have to trade this puppy away?? Thanks! Noel

Does anyone know if the scripts for the 9010 work on a 9100a?? It may also be of interest to know that someone (presumably Al Kossow) has scanned and pdf'ed a lot of the fluke manuals and uploaded them to www.spies.com/arcade. There's a fluke directory which has some 9010 scripts and the .exe to compile them, and in the TE directory there are manuals for the 9010,9100 and most of the POD's. (I presume Al wrote the scripts) Unfortunately, the user manual for the 9100 isn't there. Sigh...

Cracking the 9010A ROM signature generator
by John Robertson 15 Jun '02

15 Jun '02

I give up, I am way too frustrated by this stupid signature crap so I am going to dive into my 9010 and see if I can figure out how it is doing it. I first have to figure out if it is in the pod or the base unit, when the signature is being generated I see lots of activity on the pod data buss, so I am assuming the process is handled inside the stupid base. I am going to also see if I can figure out mathematically the difference between the fluke signature and the regular checksum by reading a small bit of data and then doing a checksum on the same bit of data, then extrapolating it from there. I suspect that the unit is taking each data line and adding it up, then the next data line...and summing them all together or in series. Gah. digging into it tonight, perhaps I can report out later this evening what I fine. Any suggestions? I am NOT an assembly language person...I can read it a bit, I understand the process, but I have not programmed with the stuff more than a few lines. If someone wants to disassemble the ROM in the base unit, the images are on ftp://www.flippers.com/public and I found a nice Z80 disassemble called DZ80 http://www.inkland.demon.co.uk/dz80/index.htm heh, heh...

Re: Programming the Fluke 9100 - Am I out of luck?

>You should be able to tell if you have the programming option by > looking for the 9 pin D-type connection (like a serial port) on the back. Nope, I don't have it, but for some reason I do have the two 25 pin COM ports - utterly useless! >PS - If anyone understands keyboard interfacing and might be able to figure >out what makes the Fluke keyboard special (and hopefully make an adapter for >normal keyboards), let me know. I have a Fluke keyboard, minus keys, that I >can loan out if someone is serious about the project. I ran across a blurb in the service manual than mentions it uses a 2400 (IIRC) baud serial interface. My plan *was* to use a COM port on a PC to emulate the keyboard (there was also a table listing the key mapping), but there is little point if it won't get me anywhere. Sigh, thanks for your help. Looks like its back to the 9010 for me :-( Alex http://www.elektronforge.com ayeckley(a)elektronforge.com To UNSUBSCRIBE from techtoolslist, send a message with "UNSUBSCRIBE" in the message body to: techtoolslist-request(a)flippers.com.

Re: Fluke - CRC's revisited

You aren't talking about the diagram on page 8-11 of the Service Manual are you? That is the signature generator for the probe. As far as I can figure out the signature is generated in the pod software. The Algorithm is the HP signature one, X(16) + X(12) + X(9) + X(7) + X as I recall. This is the algorithm generated on page 8-11. I have a friend who is trying to create a lookup table algorithm or a way of reverse engineering the data to either generate a signature or checksum from the data or a file on a hard drive (to generate sigs for referral). The data can be read a byte at a time from the pod and added in the base unit, but I don't have the knowledge to do the job at it as I have not found the help file for the Fluke Algorithm program. There are some commands that are not explained, and there should be a way of massaging the data with the base unit... Anyone find some more tapes that they can send in for the group? Any text on using the rksic.exe program?

Fluke - CRC's revisited
by Mike Coates 27 Dec '01

27 Dec '01

well, with the help of a hardware friend, I think we may have discovered why the code for the flukes checksum cannot be discovered easily - it's done using hardware! In the circuit are some NOR gates connected together, these are the feedback for the hardware CRC. We (for this read 'Phillip - the hardware' guy!) can work out what the algorithm is, and hopefully let everyone else share in this information.
