After four years, the Color Classic LCD Project con be finally! be considered complete. I initially posted about this project here: LCD Color Classic, where you can also read about the philosophy and why I had started the project in the first place. TLDR – I had a problem in one of my CC due to...

So first off, I did try to search for this particular problem and I could not find, it so if i missed it i apologize! I've also looked at all jmacz threads but they are way over my paygrade. I have an identical card to the one I posted a pic of. A Supermac Spectrum PDQ with firmware 1.27 - just...

So I started looking at older PCB from the 70s, all the way to early 90s... and there are PCB materials that look fantastic. I do not understand why no one offer these materials, and I do not mean the traces such as gold (yes pure gold and not enig) like some of the early HP lab stuff, but the...

I took a g4/350 zif from a working Yikes machine (I had it on for a few hours to check - it had to be recycled and the HD destroyed) and i wanted to put it in my Beige G3/300 to upgrade it. I had great care of the CPU. So today I open the machine, remove the original G3 and place the G4. Remove...

So as the going says “no one woe will befall you as it will always have friends silently following ” I have problems in also flashing a 7000 card I replaced the FW chip - and these I am absolutely sure are sourced thru Mouser. checked the solder and it looks good even under microscope. Tested...

So I am trying to figure out what are the supported resolutions of the color classic LB with an external monitor in place of the original 10“ CRT. The schematic attests that it is possible to drive a 640x480 monitor from the CC frame buffer - this could allow i.e. to drive the 640x480 AB...

As in the title, what are -12v and -5v rails in classic 68k macs - and also 601 and 603e PowerPC, used for ? Why is it so important? This would help in rebuilding/replacing the PSU in many vinta machines, especially when using modern ATX/SFX psu.

So I am building an LCD Color Classic and therefore completely disassembled the thing. I noticed that the lower grilled portion between the feet of the CC, that is usually considered- looking at many posts here - as merely a useless air aperture, was the original placement for the loudspeaker...

So, what the title says. I have a so-so working Color Classic, that has been upgraded in a lot of ways. It uses a 575 board, with 64MB RAM, an Apple CS1 network card, full 040, Defor's ColorFusion LC PDS video card, BlueSCSI v2, and floppy gear upgrade. The Analog board was modded to display...

OK, I got a sort of defect happening every now and then in the CRT of my CC. I always observed it, sicne I got it. The screen seems to waver every now and then, with the color washing out a bit. It happened before I recapped the AB, after I did it, and after I ddi the 640 mod. Flyback? It is...

well, the question is rather what software (7.5 thru 8.6) would I need to use these, since I don’t see any change in the Apple profiler or anywhere else if I install them in my Franken6200 with 6500 LB....

Well, the title says all, I was wondering if there's some super floppy that is considered the best drive out there. I am interested in both the manual injection models and the Superdrives... of course, in regards to the 2mb/1.44mb capacity drives.

So, I have found a small batch of IBM hard drives that I had purchased back in the day from a folding computer shop. They catered to business clients and had both the low end stuff and high end Server stuff. Anyway, I got maybe 8 of these drives, all of which are 4.5Gb, except one that is 9Gb...

So I have started restoring my Macintosh IIfx. it is a nice machine, sure there are sone in better conditions out there, mine is in what I’d presently would describe as B+. Well, maybe even A-. in any case, waiting for the gears to replace both ruined ones in the floppy eject modules. The...

Hello, I apologize if this has been already asked, however I salvaged some chips from a bombed 6200 and I wanted to know if they could be used to repair other Macs and which. One should be an EGRET chip, the other a sound chip and the last is an oscillator. The small one just floated off when I...

Hello, so I have a weird problem coming up and I have no idea how to solve it. I have a 6500 board - actually I have two boards, virtually identical, both 603ev 275MHz/512K cache, 64MB ram, with a CS II Slot. I purchased two identical Apple CSII Ethernet cards, with DIGITAL chips. I install one...

Hi! So, I am seeing a LOT of ebay sellers offering a plastic package, QFP, 33MHz 68040 from Freescale or Motorola at ridicolous prices (like this one: 68040 cpu) and I was wondering, are they real/fake? Are they compatible with a standard 68K? ...and if they are, how difficult / expensive would...

Well, I owned looong ago a Color Classic and I distinctly remember that I had it set all the time at 560x384 resolution. I needed that since Word 5.1 otherwise would display only partially the page and icons, I foggily recall, and therefore using those additional pixels helped immensely. I...

Hi everyone, I was wondering, since I have both, if it could be possible or feasible to remove with a hot air station the 8MB DRAM chips of a 5400 logic board to solder them onto the pads of a 5500 board - or, removing the chips from an old memory stick (in this case, which SIMM/DIMM should I...

H! I have found a Quadra 650 cheap on a local online classified. Too bad it was crazy dirty and the seller said it started for a second and turned off. The battery was depleted but did not release acid, and the dirt was mostly... dirt (dust, Nicotine, hairs yuck and stuff). So I cleaned...
