    Reverse Engineering the Macintosh Plus PCB

    There is someone (and I apologise that I can't remember your name) working on a replacement SE analog board for driving a LCD rather than the original CRT, something like this could be done for the 128K -> Plus however as @Johnnya101 says making 1:1 replacement boards would be hard as there just...

    Reverse Engineering the Macintosh IIsi Logic Board

    So I actually acquired one of these a while back with the intention of reverse engineering it, However it is a 6 layer board so the "trace it in Sprint" method that @Kai Robinson and me have used before would not work for this one so this would need to more advanced "reverse a schematic first...

    Help to make IIsi PSU work for LC

    The LC dose not require -5v to work, as @cheesestraws says it is only used for serial The LC will actually often work with just +5v connected, however you have to be a little carefull testing like this as the EGRET derives it's supply from the 12v rail so stability is not garanteed like this (5v...

    Reverse Engineering the Macintosh LC Logicboard

    So the LC board currently has no schematics available, I thought it's about time that changes! This is going to take ages.... I have got used to how easy it is to work in sprint, going back to using KiCad is kind of painful. That single simple page took a few hours to draw (And I just noticed I...

    Introducing (and interest check) AirTalk: Wireless plug-and-play LocalTalk dongles

    I know that feeling! I'm sitting here refreshing JLCPCB's order page to see if my order has shipped yet.....

    Reverse Engineering the Macintosh Plus PCB

    Not currently, The board is a just a tracing of the original, this makes modifying the board fun! Drawing a schematic of the board (along with the LC boards) in a modern CAD program is a long term goal, but not someting I have had the time to do yet The board design is not currently open...

    Reverse engineering the LC II Logicboard

    V1.0 has been completed and is now with JLCPCB for manufacture :) Boards will hopefully be here within a week or two

    Reverse Engineering the Macintosh Plus PCB

    Not immediately as I brought a non working (Possibly battery damaged) board cheap on ebay a couple of months ago with this project in mind I'll update here once I have the boards :)

    Reverse Engineering the Macintosh Plus PCB

    After a long wait i have finally sent the ROM-inated design off for manufacture, I might have got slightly distracted with the LC boards...... (And wanted to get these boards in before i get distracted with my next board! :) ) Hopefully I should have the boards in the next week or two

    Performa 630 DOS - No Audio

    I can proably spare a DFAC II, Let me have a look through my pile of scrap boards and see what I have

    Will this SCSI terminator work plugged into the logic board?

    Yeah that wouldn't take long, the the IIfx one passthrough or not?
