    GCC Technologies FI/30 internal HD for Mac SE

    Yes, yes, yes and I'm not sure what the checksum is off the top of my head.

    GCC Technologies FI/30 internal HD for Mac SE

    Well...the SWIM chip might be a different form factor, but the chip itself inside is identical. I made an adapter, but i've not been able to properly test it. Just adapts a PLCC44 to a DIP28.

    GCC Technologies FI/30 internal HD for Mac SE

    Incorrect. Just need to swap in the chip. The ROMs and IWM/SWIM are socketed.

    How much of the 128K/512K hardware has been reverse engineered?

    The datasheet is for the PLCC20 part (343S0042), but that's identical to the silicon in the DIP8 part (344-0042 or 343-0042). Every other spec there is the same as the DIP-8 part.

    How much of the 128K/512K hardware has been reverse engineered?

    The DS1307 is not the same. PRAM size is too small, for one. Needs to be 256byte at least.

    Voila, the SWIM die shot: https://siliconpr0n.org/map/apple/344s0061-a/single/apple_344s0061-a_mz_mit20x.jpg

    How much of the 128K/512K hardware has been reverse engineered?

    The SWIM chip is totally different from the IWM - however, the SWIM *contains* an IWM, and there's a crossbar switch that selects the relevant hardware inside the chip. The IWM is essentially a consolidated Apple Disk II controller card this is well documented. Anyone that knows CPLD's, such...

    My Weird Dual Floppy Macintosh 512K

    I have to say that lower floppy bay looks very, very cleanly done.

    QuickSANE

    Yes, by it's nature - SANE is what all apple apps use to 'math'. This will redirect all calls to that library and direct them to use the FPU to do the math.

    QuickSANE

    @JDW this would be good to run on that SpeedCard - force the usage of the FPU!

    PocketPro 25S SCSI Enclosures

    Looks reasonably doable - although, the 2.5" scsi disks would be impossible to source - would be better to adapt the design to something like the BlueSCSI instead, then you can simply do a case design - no need for external power, either - if @PotatoFi's mini mac II case for Raspberry Pi's is...

    TinkerDifferent - Gamer Tags & Usernames

    This weekend, I was thinking about the fact we're at 700+ members and some of us might also game, on some platform or another. To this end, i've made a simple spreadsheet here if you want to add yourself and open up your friends list. I've added my name to the pot already :)...

    Will the dos card for 6100 work in IIci?

    Nope - totally incompatible.

    Lessons learned the Hard Way

    For me it was learning when to stop. Both in terms of overall process, but also on an individual job. When you're tired, you make mistakes. All too often i've been soldering something together, or designing a reloaded board, and then missed out something really obvious because my brain was...

    Logic Board - Macintosh SE Reloaded

    That's odd as i didn't change the hole sizes for the maceffects board gerbers - must just have been a manufacturing thing with the blue ones!

    Problem with Total Systems '030 accelerator in Plus

    The location of U1F etc is easily found by looking at the X and Y axis of the board. Along the bottom, numbers. Along the side, letters. Draw an imaginary line to follow the location. So U2C = the IC located where the number 2 intersects with the letter C :) Silkscreen nomenclature is: U =...
