@Brett B. - Very true. With a bit of patience and luck you can build your past days dream machine for almost nothing - as long as you are not behind things like an original 128k or a Lisa, or a 20th Anniversary Mac etc. I've had this 630 for almost 20 years, when it was thrown out of a...

Thanks again @davidg5678 - I will do as you recommended. First replace all suspicious parts and only then try to turn up the voltage. The AB I recapped was not looking too bad and was working (albeit wobbly) before. The caps were leaking just a bit from their underside and the goo was only...

Any more Information about how much you turned it up? I have not yet measured the 5 and 12 Voltage rails but I will do that when I have read up about how to do that - hopefully tomorow. Somewhere I read that one has to be very, very careful to not fry anything permanently when increasing the...

Wow, 196 MB sounds impressive, If I can find SIMMs that big. There remains the question what software to install that needs that amount of RAM on System 7.5.5 :-) It would probably easier to fill up RAM while using MacOS 8.1 - Only I never could get the DOS card running under that system...

Thanks @davidg5678 for confirming the placement of the Optocoupler and also Links to the part numbers! I know enough electronics to know what diodes and optocouplers do, but I'm not confident enough to be sure with what to replace them with if I don't have an exact part number. Now I can order...

OK I see. The thing is, I have another board from a 110 V Classic, that looks a bit different (Its number is 630-0525). The flyback transformer looks different and capacitor values are also not the same. I take it, this is just the other revision I have read about. How can I tell that, and what...

Yess! - This sounds encouraging as hell :) - I'm not sure if I include another Fan, besides the Power Supply, but I will definitely add a heatsink. The 486 has one already, the 68LC040 does not. I've read something about the RAM limits not being that strict already. I found the 32 MB Sticks...

Hi! I have a Performa 630 DOS Compatible that I want to "spec to the maximum" - at least as far as possible. It came with the DOS Card and a Comm-Slot Ethernet card. I increased the RAM to the maximum, replaced the HD with a CF card and was given an AV-card and tuner for it. Now i secured a...

Hi! I have a Mac Classic that is working fine but has a wobbly screen. The "wobblyness" is more apparent at the top and can be linked to Harddrive activity. Moving e.g. a white window in front of a dark background does not skew or wobble the screen! I'm in the process of completely...

The connector is called Mini-DIN-4 and you can also get it new if you don't have any old S-Video stuff lying around. https://en.wikipedia.org/wiki/Mini-DIN_connector

Nice to hear. Just make sure the device node is writable of course. I think it should be obvious by now, but I somehow edited out the fact that I did this under Linux in the first post. Now I can't find where to edit that post, so here you have it ;-)

Well, you should be able to use "Go to" from the Finder. I'm not too experienced with current OS X tough, and there have been some changes about where the filesystem is mounted when the machine is running, so /dev/ might or might not be the correct place. Regarding Commandline arguments to...

I forgot to add - I'd like to hear if this is also somehow possible from modern OS X? I have no hope for Windows tough ;)

Hi! Maybe this is old news for everyone, but I just discovered how to directly access a floppy disk from minivmac without any of the usual detours using disk images and the like. Using an external USB Floppy Drive, it is possible to directly drag and drop the /dev/sd* device file on the...

I would snip off the legs and then desolder them. Then attach wires to a separate battery holder that can be attached somewhere as far away from the board as possible.

Hi! Just writing to tell you that you are not alone. I have a Classic opened and waiting to be recapped for a few months now (Logic and Analog board). I could have used the cosole5 link a bit eralier, since I had to check all caps myself. Well at least I have something to compare notes :) I...

Thank you indeed. This is not mentioned anywhere but I can easily confirm it by looking closely at provided pictures. In fact I was not even aware hat AGP Pro existed until now - which I am a tiny bit ashamed of ;-) So I'll get a Radeon 9600 instead altough I discovered in the meantime that...

Hi! I have a 2004 G4 MDD - Apple's last machine capable of booting OS9. It has its standard Radeon 9000 installed which is fine for OS9, but does not support Core Image on OS X. Not that I really need it, but I could get a nice 256 MB Radeon 9800 XT from a PowerMac G5 :) Now there is my...

When the OS X support for PowerMacs was waning, I switched to Debian Linux and used said PowerBook as my main machine up to about 2009 - So my experiences are a bit dated. I'm a Debian guy and that's what I used. Power and temperature management were working fine, but only after I discovered...

I used a 2005 1.5 Ghz 12" Powerbook for many years, first with OS X (10.4 and 10.5) and then with Linux. It always got uncomfortably hot when used for things like video compression. I still remember the quite common jokes about not using it on your lap if you still planned to have children ;-)...
