Hmmmm I might  drop it down a slot in that case and try again. I was getting a fair bit of wierdness all round after I put it in so that is likely the answer... the more you know!

Sad to hear the demise of such a machine. Q: Cant the U3 memory controller desoldered, the pads cleaned up and fixed and the chip soldered back on?

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…

Bummer they are nice machines. I have the original 1.6 single CPU machine and it works great, but slower then my other DC 2.0GHZ PCIE models. So many decent motherboards end up dea…

Well thanks for the information. Figured I will still pull out the multimeter tomorrow and check the power supply but if that's not the problem then I guess see what I can throw in…

They all had the memory controller issue, excepting the final multicore machines which have the far superior U4 memory controller. Let me put it this way; your model here had a 40%…

I thought these only had the ram slot problems after the board had been over flexed. This still has the stock amount of ram512mb.

It's probably dead. Not kidding. That was the model I owned; absolute heat pig. I'd start with the PSU, you can also check the caps on the board. Most likely is that the U3 memor…

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…

Pitou said: @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 …

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.

So found this computer in the neighbors garbage today only thing missing is hdd. However when I plug it in and press power button I get nothing. This is my first time touching one…

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…
