Missile command signatures?
by David Shoemaker 07 Nov '11

07 Nov '11

I want to try signature analysis on this board but can't find the docs that list them for this board. Anyone? _______________________________________________ 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/

Logic levels question 6502A (Missile command)
by David Shoemaker 06 Nov '11

06 Nov '11

I am trying to trouble shoot a board. I am getting some odd responses reading the roms. I noticed that the address lines coming from the 6502 seem to be going high at 3.5 - 3.7 vdc. I suspect this is causing some of the ttl to not latch high. This is checked through a meter using the fluke to read a particular address on a loop and using my scope for the same and while running the game. Is this a normal value? I don't see any pull-ups on the address lines on the schematic.

The +5v line is nice and clean. This is an old school ttl board so should be +5 for logic high I thought _______________________________________________ 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/

I see on the http://www.quarterarcade.com/tech/CodeGenerator/ page that it mentions importing a mame driver to generate the script. But for the life of me I can't figure out how J Anyone?

Inverter was definitely bad. Light was working fine but a component on the PCB was getting red hot. Sadly the PCB is now chargrilled :( ----- Reply message ----- From: "Rodger Boots" <rlboots2(a)gmail.com> To: "Technical Tools Mail List" <techtoolslist(a)flippers.com> Subject: [Techtoolslist] ABI Boardmaster 4000 part needed Date: Tue, Nov 1, 2011 16:30 Funny thing, inverters. If the backlights are bad the inverter won't run and if the inverter is bad the backlights won't run, so it's hard to tell which is bad without replacing one or the other. You might try finding an equivalent display at DigiKey and see what converter they sell for it .

ABI Boardmaster 4000 part needed

Hi all, I don't suppose anyone is breaking an ABI Boardmaster 4000 are they? The inverter PCB for the display is shot in the one I have here and I think it's beyond repair. The machine is still usable but as it's only on loan from someone I really need to get the backlight working again before returning the unit. Typical that these things always go up in smoke the minute you borrow something!! Thanks, Martin.

Reading 9100 floppies...
by John Robertson 27 Oct '11

27 Oct '11

Has anyone lately tried to archive floppies from the 9100 series machines? I found a program called OmniFlop that works on most PC platforms including XP and it supports something like 250 odd floppy formats. http://www.shlock.co.uk/Utils/OmniFlop/OmniFlop.htm You see I am currently selling a 68030 adapter and found when I opened the package that there was a 720 DS floppy and wanted to archive it for the gang here (scanned the manual as well) - the OmniFlop program gave two formats - one being Acorn ADFS L, the other being Gravograph. My original 9100 archive setup is packed away, and I can't recall the name of the floppy reader software... So the question is, are either of my archives going to be valid? I made two archives using each of the two formats. I've put the two images up on the FTP site - ftp://ftp.flippers.com/TTL/TestEquipment/Fluke/68030-Adapter John :-#)# -- How to subscribe or unsubscribe from TTL http://seven.pairlist.net/mailman/listinfo/techtoolslist FTP site is: ftp://ftp.flippers.com/TTL/TestEquipment _______________________________________________ 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/

Tru using dd command in Linux, it create a raw image of disk dd if=/dev/floppy of=NameofImage.bin Oct 19, 2011 10:00:58 PM, jrr(a)flippers.com wrote: =========================================== David Shoemaker wrote: > Not sure what I am missing but why don't you use the tool to make a > disk from the image and see if it reads in the 9100? > > I would also then archive the copied disk and diff the two image > files. If all went right they should match. (don't think this hit the mail list) True, if I had a working 9100 at this time - which I don't! I could use the 9100 to duplicate the disc as well. I haven't had time to put together a working 9100 system for a while, too many other business pressures, hence my trying to solve this by finding a simple archiving utility. I now suspect that the XP computer (or its 3-1/2 drive) I am using is not compatible with the requirements of the OmniFlop as it does not show this 68030 support disc as OS9 even though it supposedly recognizes OS9. Will try to resurrect my older portable machine that did work (at one time) for archiving/copying OS9 discs with a universal copy program...that darn boot/copy floppy is here somewhere...

Not sure what I am missing but why don't you use the tool to make a disk from the image and see if it reads in the 9100? I would also then archive the copied disk and diff the two image files. If all went right they should match.
