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...

Hi, I am wondering if a 8.2" flexible OLED or TFT display could be used to replace a CRT in a Color Classic Mac. This, since the CC uses a Trinitron cilyndrical screen, the curvature of which could be easily replicated by an appropriately sized display. i see a lot of Takky and/or other very...

hi everyone, ive also found this board together with the Mac II, ive also searched the forum however it may be one of , like, six different NuBus graphics adapters from Supermac. I am trying to positively ID the board and then find out if it works, shere to find drivers and also whether there is...

Hi everyone! I have found my old Mac Quadra 700 (and also some other goodies, namely a LC/475, Apple II/c and a Mac II cx) in my mom's attic. The were left there for the last 20 years or so. I had removed batteries from these ancient machines so no damage! But, I am very wary of powering them...
