    Anyone here handy with a disassembler like IDA Pro?

    Specifically, i'm trying to run Macintosh ROM's through it. While it can decode snippets of functions - it dumps a lot of 'data' it thinks - it can't determine what's code and what's not. Also, the references, while they line up, seem to be scattered around, and the visual graph looks like...

    1987 Macintosh Plus (Platinum)

    Well, this just fell into my lap! Literally never really thought about getting a Plus before as it seemed kinda pointless with me having an SE...well, a few/eight SE's and SE/30's in various states of being broken... However, I told myself that if i ever found one for a non-silly price, with...

    MOS CPU Replacer for C64

    Came across this today - would be ideal for anyone looking to resurrect a dead machine without having to resort to cannibalising the ever decreasing number of working machines out there. https://monotech.fwscart.com/MOS_CPU_Replacer_(65108501)/p6083514_21591072.aspx Technically it'll replace...

    Macintosh SE - PLCC ADB Adapter board

    This will allow the use of the PLCC ADB Transceiver in the Macintosh SE, which is the only model that uses a DIP18 part. There's not much to it other than that! @Branchus has used one of these, successfully, in a troublesome SE, iirc. The github page to the project and the gerbers, is here...

    Macintosh SE - Discrete logic GLU replacement

    After Porchy from Jammaarcade got us across the finish line with reverse engineering the original HAL16L8, i thought the functions might be possible to replicate using discrete logic. This would of course be to benefit those that are making an SE Reloaded board, who don't want to, or can't...

    Everything you wanted to know about the BBU, but were afraid to ask...

    What differentiates the Macintosh SE from the rest of it's forebears? Well, the fact that the PAL's of the earlier 128K, 512K & Plus machines have gone away and been replaced by a single custom ASIC. The original Macintosh was designed around a single ASIC called the IBM or 'Integrated Burrell...

    Fitting a Magneto Optical drive into a Power Macintosh G4

    While you may know that Power Macintosh G3 & G4 machines came with ZIP drives installed (as a CTO option), you can use any other ATAPI 3.5" device in that bay - it doesn't have to be a ZIP drive. In this instance, i'm going to install a Fujitsu MCE3130AP 1.3GB ATAPI Magneto Optical drive in it...

    Confit Garlic

    If you like Garlic, seriously, try this. I've seen lots of recipes lately that use a whole bulb of garlic, where you slice the top off, add a little olive oil and salt, wrap in foil and roast it in the oven. You get an amazing flavour, quite quickly. However, the garlic can start to caramelise...

    Apple Cinema Display - 20" Polycarbonate ADC

    I've technically had this since last year, but I didn't have the time to even unbox it. Today being the first weekend in seemingly forever where I'm not ill or in pain, I'm actually digging into my mac pile! Still looks stunning, 20 years later! This will be going along with my...

    Big stack of logic boards...

    So I took a punt on an auction that included three SE/30 logic boards, two were really really badly recapped, one was battery bombed. However, these will all be donors for a Bolle SE/30 Reloaded board run! As a bonus, I got a half stripped colour classic board (although the customs are all...

Once assembled, you...

    Amiga Square 5-pin DIN Power Adapter Replacement

    So, most 'wedge' Amiga's use a wierd variant of the 5-pin DIN, in that it's SQUARE. These plugs, and sockets are wayyyyyy out of production and almost all new-old-stock stuff has been used up. This was originally flagged on the Retro Tinkering Discord, and reposted on our TinkerDifferent...

    Doom 3 BFG Edition

    The Mac community seems to get the bum end of the deal when it comes to AAA gaming - in some cases for good reason, Apple seems to make it as hard as possible to develop them on the platform by refusing to support industry standards, instead preferring to go it's own way. However, thanks to...

    Tomeviewer

    in case this has been forgotten to the annals of time, Tomeviewer is useful to be able to poke around inside and extract files from Apple installation tomes. Luckily, some enterprising sod has put this up on Macintosh Garden: https://macintoshgarden.org/apps/tomeviewer
