I'll take one.

It could be a bad power supply, or maybe you just need to adjust the color pot.  A lot more information than you have given would be necessary to make a more informed diagnosis.....

 

computer type, monitor type, only this game or others, did this just star suddenly, how is the monitor connected....composite, svideo, rf...???

On Omnimon, Ill double check the rom I posted, I just dumped the 8k Omnimon last night so Ill be sure to get the correct one posted up.

Hey Curt,

 

Just wondering if you'd ever gotten around to re-dumping that 8k Omnimon EPROM?  It will need to be dumped twice, once with the switch attached to the wire in each position to get the entire 8k.

Finally got around to dumping the ROMS from my RAMROD.  Math pack was the standard Atari chip so I didn't dump it.  The hotkeys seem to be working with this version.

Is there a way on windows to un-ARC these files? I have tried some programs that say they can but report the file is bad.

 

Altirra....You can mount arc files as a disk

[What drive do you have with your ATR8000?]

Mine came with 2 Teac FD-55B-01-U mechs.  I have since swapped one of them out for a DSDD mech from my old PC-XT clone for better compatibility with other Atari drives.  Not sure of the model on that one.

 

As the Doctor says, straight through cabling, correct DS jumpering, and proper termination at both ends of the cable are critical to get these working.

One for now.

[Newell OSN for 400/800]

I did recently (well, over a year ago actually) pick up a Ramrod Board.  I haven't really gotten beyond just verifying that it works.  It does appear to have OSN and Omnimon on EPROMS, but just the standard math pack ROM. I really need to get those dumped.

 

I plan to try the various Newell rom combos on my tf_hh 48K board when I get around to installing it, but I don't see why they wouldn't work.

 

Sigh......too many projects!

I've written before about how the ATR8000 would be capable, and I've already started some preliminary work on the ATR8000, but again, not having one..

I just dusted off my ATR8000 and all appears to still be in good working order.  Happy to test when you have something.

Just trying to understand if the problem is with the DOS 2.5 disk, or if the drive "broke" after you successfully booted the paperclip disk.

[Indus GT Weirdness]

does the paperclip disk still work?

Nice! Looks like you have the Co-Power board in yours too!

I'd try the padded one.

@JR> I am hesitant to do any further flashing of ROMs on my ANTONIA board though because of its apparent sensitivity to the configurator version.  Unless I can get this problem sorted out, I am going to stick to what I currently have installed lest I end up getting truly "stuck" with one OS.

You should really never get "truly stuck".  You can always remove the ROM jumper on the Antonia board to get a clean boot off of a protected OS ROM slot, so that yo can flash ROMs even if everything flashable gets corrupted.

[ANTONIA configuration tool incompatibility question]

Have you tried re-flashing OSb?  I know my roms have become corrupted a couple of times, for unknown reasons.

Here's my 2 AT88-S1PD dumps. Hand written labels. labeled v1.11 1/9/84 and v1.21 5/4/84. Both also have 0073 written on the label.  Both are later DD models with just 1795-PL controllers and half height mechs.

I'm trying to get one of these in my 800 right now, and I'd like to use the onboard monitor connector.  When I cut the connector off the cable, where should each of the wires be soldered? 

To the same pins they go to on the connector you cut off?
