Shiny New Computer Setup
Upgrading to a new computer is exciting, but can also be a pain. Last week I replaced my primary desktop computer with a new laptop, and the setup has involved some bumps in the road. Read on for my take…
Explaining 4K 60Hz Video Through USB-C Hub
USB-C offers exciting new capabilities, including external monitors connected through the USB port. USB-C converters to DisplayPort or HDMI are common and inexpensive. USB-C hubs with external monitor support are also common, but understanding their capabilities and limitations can be…
Floppy Emu May Feature Update
New features are blooming like May flowers for the Floppy Emu disk emulator. This firmware update has something for everyone! Lisa The emulated rotation speed of Lisa floppy disks can now be manually adjusted within a range of +/- 6…
More AVR ICSP Footprints
I’m continuing to research options for alternative programming headers for AVR microcontrollers, building on the ideas I discussed earlier. For one-time programming purposes, the standard 3 x 2 pin 0.1 inch header is just… too big. I’m on the hunt…
Take a Tour of BMOW Labs
They say you can tell a lot about a person by looking at his work-space. I thought it would be fun to take a break from stuffing boxes today, and make a short video tour of the BMOW Lair. I’ve…
Alternative AVR Programming Header Ideas
That ubiquitous six pin header for in-circuit programming of Atmel AVR microcontrollers – it’s the standard, but it’s not a great standard where size and cost are a concern. Can I do better? Programming most AVRs requires a six wire…
Daisy Chainer Testing
Good news: the Daisy Chainer for Floppy Emu is finished, and working nicely in all my tests. With the Daisy Chainer, a mix of real and emulated disk drives can be combined into a single Apple II daisy chain for…
Floppy Emu Firmware Update: Smartport Unit 2 Mode
Celebrate Friday with a firmware update for the Floppy Emu disk emulator! This firmware adds a handy new disk emulation mode for Apple IIGS computers called Smartport Unit 2 mode. It’s what I called “chameleon mode” in an earlier post,…
Floppy Emu Chameleon Firmware
Here’s a fun party trick: firmware for the Floppy Emu disk emulator that emulates a 5.25 inch floppy drive, but then reconfigures on the fly as a Smartport hard disk emulator. Why is this useful? It’s not obvious at first,…
