    Gluten Free Vanilla Sponge tray bake

    This totally isn't to make @Mac84 jealous and hungry, I promise 😂 This wasn't made by me, but by my wife, @boopbox123 So, it's a gluten free sponge, using xanthan gum, cut into squares - each square has the centre cut out, filled with seedless raspberry jam and then the centre put back in...

    Power Macintosh 475

    The mythical beast that is the PPC601 Upgrade card, and the LC475, smashed together! This started life as a Japanese LC475 (no different to any other 475, but it's from Japan and therefore, cooler than yours). It actually came already with a 32MB SIMM in it and 2 x 512kb VRAM SIMM's, but no...

    Unitron (Brazilian 128k Clone) PAL Equations

    http://www.merlintec.com/download/unitron1.pdf http://www.merlintec.com/download/unitron2.pdf I uncovered these a while ago, it may help to reverse engineer the PAL's used on the 128k, 512k and potentially, the Plus. All of this is courtesy of a genius by the name of Jecel Mattos de Assumpcao...

    The PAK68/3 Accelerator - [German]

    Some of you may be aware of the PAK68 line of open source accelerators, originally published in the German C't Magazine in the 1990's. This was intended to be a 'universal' 68000 accelerator, for the Atari ST line, primarily, but with modifications you can make it work in an Amiga or a...

    ATi FireGL X3 256MB - AGP

    Brand new, from Germany! For €30!! This is equivalent to the Radeon X800XT and will work in AGP PowerMac G4's once the EEPROM is flashed with the X800 XT ROM and the requisite pins are masked off on the edge connector. Best part is, the seller has dozens of these - they're ex-HP workstation...

    PowerPC G4's - MPC7410RX500LE

    I literally found these in my parts bin - ideal for upgrading G3 machines, or for 1st gen G4's. These are 500 MHz parts. I honestly don't remember why, or when, I bought them! Anyone want their iMac DV upgraded? 😛

    Formac G3 ZIF carrier - Repair

    So a while back, I bought one of these: a Formac ProG3 400-50 ZIF carrier card. It came with the ZIF G3 daughtercard, but no heatsink. I finally tracked down one from a B&W G3 and mounted it. However, after years of use, this sockets mounting ears have become horribly brittle. Superglue...

    128MB 72-pin SIMMs!

    Thanks to @phipli for these! I have an PowerPC upgraded LC475 with one of these SIMMs names on... 640MB ought to be enough for anyone... Right?

    Quadra 650 logic board

    Finally got my hands on one of these! I have a IIci case, a dremel and a plan...! If anyone has a power mac 7100 logic board, I'll take that off your hands, too. For now, this grotty bastard is going for a wash...!

    Apple Custom ASICs

    Something i've been working on, is a list of all the Apple Custom ASIC's, where they're used, and also the pinouts of the chips in question. I've started with the Compact Macs so far, but i'll be expanding this over time. If anyone has access to internal Apple datasheets for any of these parts...

    Power Macintosh G4 - 733

    Excuse the sink full of washing up! This arrived a week ago but I've not even had a chance to unbox it! I'd like to get a dual cpu upgrade for this, or should I install my Sonnet Encore ST/1800 that I scored off @Bolle a few months ago? I do also have a Radeon 9600XT from a G5, and a Geforce...

    Sonnet Crescendo G4-400MHz

    Bought for a bargain, from US eBay - sold as not working - seller stated it wouldn't boot into the OS, or froze. I have an inkling that it's either the correct extension not being loaded, or there's an issue with the cache. The cache sits on the rear of the card and it looks like a QFP that's...

    Sonnet Tango 2.0 - BNIB

    Look what I found! Brand new, boxed! Hoping that my Power Macintosh 9600 will work with this...

    Flashing an Adaptec AHA-2940UW to Mac

    So, i seem to recall when i was working in the DTP/Pre-press industry about 20 years ago, UW SCSI was the absolute best thing since sliced bread. All those high density 68-pin cables and nice trapezoidal chunky connectors....aaah, those were the days. Anyway - I have before me, an Adaptec...

    5v FPM DIMM's!

    These are getting surprisingly harder to find. Seriously, this haul of 4x64MB and 2 x 32MB DIMM's cost more than a 32GB DDR4 kit... But it'll be worth it! The extra 256MB is destined for my 9600, the other 64MB destined for the 7500. @Zane Kaminski - reckon you could make these with more...

    Macintosh connector part numbers

    As the title states, i'd like to compile a list of all the connectors used in Macs, and to do that, i'd like to ask anyone that has knowledge of a particular part number to add it here. Once i've got a list together, i'll make a sticky post in the relevant section. So far, from @trag we have...

    Sonnet Crescendo G3/400

    Got this for $100! Boxed! It's so wee! 😂 Now it was sold as working but I've yet to test it...

    More Magneto Optical fun! This time, a Panasonic LF-3000E...

    This is part of a haul that included a Macintosh 8100/100AV and a 15" Sony Trinitron Monitor. It came with 5 x 128MB Cartridges, a cleaning cartridge and the manual and original SCSI cable. It's sooooo quiet compared to a ZIP drive, but about the same or slightly slower speed - 33MB took...

    USB Zip 250

    From eBay, as a buy it now, with no less than 22 assorted zip disks, some even still sealed! Not bad for £45! Finally I can use my PC to transfer stuff!
