I'm bootstrapping my Apple IIC (x2) machines with ADTPro running on M2 MacBook Air via an FTDI adapter - and while I can transfer data, I can't successfully write out disks. The problem is hit whenever I try to write an image via the ADTPro software running on the IIC. Whilst the transfer is...

Having figured out the first of two Macintosh 128 boards I acquired (https://68kmla.org/bb/index.php?threads/macintosh-128k-board-with-custom-512kb-upgrade.48789/), I'm now trying to repair the second. I'll add pictures shortly, but it appears to be an 128KB board upgraded to 512KB, which...

I recently purchased a Mac II that had been upgraded to a IIfx - it has the original case but an upgraded motherboard, and both an 800K and 1.44MB drive - and have been trying to get it running again: - Firstly, I installed new batteries and turned it on to get a chime - However, I was using a...

I bought a Mac 512 on eBay recently which had a spare upgraded 128 board thrown in - complete with new sockets, chips, and a hand-wired PCB in the corner. Basic testing shows that it appears to boot to the floppy OK, albeit I haven't actually tested the memory - but does anyone recognize the...

I might be a glutton for punishment, but I have a Mac 512 with a cracked case which I'd like to repair. I *suspect* it may ultimately need painting, but I'm trying to glue it back together as a first step - given that the cracks disappear with the right pressure applied. Can anyone recommend a...

My SE/30's display is shifted over too far to the right, and I want to center it. I've searched through the forums, and I understand that I need to adjust the rings on the back on the display. As much as I'm wary of doing this due to personal risk, I also can't identify exactly what to tweak -...

I've been fixing up an SE/30 and got to the point of repairing the floppy drive. Having replaced the eject gear and lubricated the mechanism, I now find that, from the moment I turn the power on, the drive motors spins up without ceasing while the eject mechanism repeats endlessly - until I turn...

I'm trying to rescue an M5126 portable which formerly wouldn't start up at all - and so the first thing I did was recap. I've tried to avoid reassembling in full until I'm sure things are working, so I've carefully reconnected (with layers of insulation!) the battery holder on top of the PCB...

If I have an SE/30 with an internal SCSI drive, then the drive should have termination enabled. However, if I then add an external drive - do I have to disable the internal drive's termination and add it externally (replacing it with a terminator when the external drive is not connected), or...

I have a Mac Portable M5120 with 2MB RAM, and I'm curious to know what options there are for RAM expansion at this point. MacEffects used to sell an 8MB card (which I believe Techknight designed?) which is now out of stock, but I also think there may have been schematics on this site before the...

I have an SE30 that I'm resurrecting, but it won't format floppy disks successfully - the format goes through, but verification fails more or less immediately. However, I have another SE/30 MLB - and if I swap it in, the floppy formats fine every time. I've replaced RP10 with no change - am I...

I have 8 x 16MB OWC 30-pin SIMMS I'd like to use with my SE/30. Unfortunately, even though they're lower in height than the ROM SIMM it came with, I find that the last SIMM snags consistently on the metal lip of the cage above it as I insert the motherboard and comes loose. Questions: - Is...

So (and I apologize - this isn't strictly a Compact Mac question, but I figured the colors were shared): I have an Apple 5.25" drive in Platinum, and it's been extremely aged and yellowed by the sun. I figure I have three options to restore the color: - Retrobrite. This has mainly worked for...

So I have a: - SE/30 with a recapped power supply - Set of Bolle's boards, including the Turbo 040 and combined network card / IICI slot adapter - Radius Two Page Display card I'm not... totally convinced that the Two Page Display card is a worthwhile addition to this combo, but was amused to...

After resolving the power supply issue with a bad switch (https://68kmla.org/bb/index.php?threads/dead-se-30-power-supply-no-fan-no-voltages-at-floppy-connector.39895/#post-430859), I then booted the Mac to be greeted by a working fan and... a continual but quiet ticking sound with no chime and...

I grabbed an SE/30 from Craigslist tonight which was sold as dead. Returning home, I found a couple of things: - The motherboard was actually in good shape, with no obvious major battery or capacitor leakage. That said, one of the vias by the battery (just one!) was green and corroded, although...

I have an SE/30 with a soldered CPU, and found a Daystar Digital 40Mhz accelerator - which obviously needs a socket! I'm comfortable with re-working PCBs, and have a desoldering gun that should make short work of removing the existing 68030 from the board - along with a new Mill-Max socket...

So I dug out a Mac Plus and SE/30 that had been sat in storage for a while, and apart from a failing hard drive in the SE/30 they booted fine - while, more importantly, there was no evidence of battery leakage (that said, the SMT caps were leaking and needed a cleanup - I'll get around to...
