I'm not able to get into Applesoft BASIC using ctrl-reset. I also tried running BASIC from a system disk. See this video. test.zip Any idea? Pitou!

The Q800's PSU might not be able to handle two PC Cards. I would recap the PSU First. If the PC Cards can do background processing, then maybe it can be done. Like Trash80toHP_Min…

Perfect! I did have M0420 in the list at one point, but could not find a visual example of one for sure. So this helps a bunch!

Byrd.....  Thank you for your post.  If I had a schematic of a Color Classic analog board, I could figure some of this out for my self, but I can not seem to find or buy any docume…

As I said, I've got a couple of Mac Pluses with the model number M0001AP. For interests sake, I also have a couple with the model number M0001A, yet they all have 240v PSU's (which…

That would be great. As long as they are model number on the units themselves and not variations on them. Like the IIcx is M5650 but the model in the serial is M5658 because the ha…

I've had a couple of M0001AP's, they are Mac Pluses with 240v PSU's. I can take a photo if you would like? Also, there is a Macintosh Classic with a different model number which h…

Interesting, they wouldn't be working together/cooperatively like Radius Rockets do under RocketShare. Never tried it, but I'm all but certain two Rockets could not co-exist peacef…

Hmmm... Well I am not sure why anyone would remove the serial and FCC label. The FCC label I can see happening for some reason. But the serial. Its not easy to remove without resi…

Where are the ROMs? I think it's not a prototype. I think it's a machine that has been through too many repairs and parts changes.

I doubt this is a prototype given that all of the stuff that is missing/different wasn't changed between the original and the 512k. It seems like this poor 512 just happens to be m…

Transplanting something like this requires considerably more work and modification than the VGA mod on a CC board.  CCs are not that rare and you could always keep a junker/spare C…

Any other differences from a production unit?

So what I thought was a junker 512k might be a prototype. I started to strip it for parts, but I noticed some weird things. For starters, both the bucket and the bezel stickers a…

Have you considered taking the 575 components and mounting them in a custom case? That way you can make the front flat to mount an LCD? Your woodworking buddy could probably make s…

No clue. Since they are two different brands maybe the driver software won't conflict with each other (if you run one at a time). Any reason you need 2 DOS cards in one machine?

Can it work? I have a Reply card in my Q800's PDS slot and I am seeing Orange DOS card on eBay (nubus) that will fit in my Mac.  Can 2 or more DOS card work together?

the guy who figured out the 640x480 mod, I have no idea how he figured it out. Maybe it came from an internal apple employee, or repair guy. Hard to say. 

@Gorgonops, ok thanks, will try that. I have another question about the ROM chip. it's a 128kx8, so it needs 17 lines of addresses in order to access the entire memory of the rom.…
