RFI: 9000A-Z80 Pod EPROM
by Fish, David 25 May '00

25 May '00

Hi Folks, Has anyone archived the EPROMS inside the 9010A pods? I need someone to verify the checksum of mine or send me the image of thier EPROM. I've disassembled the code in order to understand the communication between the pods and mainframe but there are several instructions that just don't make sense. The EPROMS should all be archived anyway, they're getting to/at that age where the bits start to evaporate. The STANDARD checksum that I get is: 785E Thanks in advance.

Problems with mail server
by John Robertson 24 May '00

24 May '00

Hi Folks! Sorry, but I inadvertently ran out of storage space at my web host (50 megs) and they automatically shut off mail...sigh. So I now have 100 megs of storage, and all should be working fine now. If you had sent any messages to the mail lists, they should work now if you resend. Sorry about that!

Info on the 9010a/9100 Pod communication protocol?
by Fish, David 11 May '00

Does anyone have any information on the communication protocol/method that's used between the 9010A (or 9100) and the processor pods? Any info would be appreciated.

Hi John, I've been a little slow with this one, since it doesn't apply to a Fluke 9100a system, but the checksum calculation is interesting :) Can you email me a copy of the rom dump so I can have a look at it Cheers Chris To UNSUBSCRIBE from techtoolslist, send a message with "UNSUBSCRIBE" in the message body to: techtoolslist-request(a)flippers.com.

Damn.. Another case of the "forgot to check the To field". That was obviously meant for John Roberts.. > Maybe RomIdent should just be updated to use either > checksums. That way all fluke systems would be useful for > identifying the roms. Of course, all of the roms would have > to be fed into it to populate the database. > > Jon This assumes that you know the rom layout in memory and that Theirry would add the database. Of course, just running a program on your "spare romset from another board" (ie convenient backup from the net) would give the same results.

RE: Fluke 9010A Checksum Hack

Of course, now that the fluke checksum method is known, it should be pretty simple to knock up a program to perform and display a checksum for a rom image..

Fluke 9010A Checksum Hack
by Fish, David 08 May '00

08 May '00

Hi Folks, Since there seems to be renewed interest in this project I might as well 'let the cat out of the bag'. I've been working on this project for about a month so far in my spare time and I'm close to completing it. I've already emailed Jess and John to let them know, but I don't think John got his email, our system went down due to the virus and it may not have made it out. Anyway, so far I've got the code disassembled, all the message and look-up tables mapped out and the I/O routines located. I got my emulator hooked up to a 9010A and it finally functional (forgot to disconnect the two watchdog traces). On Saturday, I located the Checksum routine. The 9010A seems to perform an accumulating XOR Checksum calculation. I'm not sure what type of calculation PROM programmers use but I'm guessing it's just addition. Any know for sure? I'll let you all know when I've got the hack completed. David Fish "We want...Information.

DRAM tester...
by John Robertson 05 May '00

05 May '00

I just bought a nice little DRAM tester from Robert Doerr for only $65US, looks nice, just needs a box. Can be modified to test 4116s! I suspect it can test more RAM with a bit of tweaking, and the speed and voltage is adjustable to find the fall-out parts. (not up to spec) His email is rdoerr(a)home.com John :-#)# John's Jukes Ltd. 2343 Main St., Vancouver, BC, Canada V5T 3C9 Call (604)872-5757 or Fax 872-2010 (Pinballs, Jukes, Video Games) http://www.flippers.com "Old pinballers never die, they just flip out."
