I’m continuing work on the daisy chain adapter concept for Floppy Emu, and I’ve run into a problem. There’s a pulldown resistor on the Floppy Emu board that’s too weak (resistor value is too large) to reliably pull the voltage…
Today I’m thrilled to announce the newest member of BMOW’s Floppy Emu disk emulator family – the Model C. Floppy Emu is a floppy and hard disk emulator for classic Apple II, Macintosh, and Lisa computers. The new Model C…
I often obsess over little details of my circuit designs, and the daisy-chain adapter for Floppy Emu is no exception. The design needs a small CPLD for the daisy-chaining logic, and for various reasons I have narrowed the choices to…
Some Apple II computers can daisy-chain disk drives: connect multiple disks, one after another in a single chain. I’m exploring options for the BMOW Floppy Emu disk emulator to support daisy-chaining more flexibly than it does now. I’d love your…
All good things must come to an end, and today it’s the end of the Macintosh ROM-inator II SIMM and SIMM programmer. The DIY ROM-inator I kit was discontinued a year ago, and now the ROM-inator II is also being…
Happy birthday and merry Christmas, Apple II collectors! I’ve decided to make a gift of my design for an FPGA-based disk controller card, and release it under a Creative Commons – BY-SA license. This means anyone else is welcome to…
