Who needs a logic analyzer? You do! If you enjoy working with electronics, a good logic analyzer is an indispensable tool. It lets you examine exactly what’s happening with your data signals, so you can troubleshoot problems quickly or reverse-engineer unknown protocols. Developing digital electronics without a logic analyzer
Remember the Pippin, Apple’s ill-fated attempt to enter the video game market? The hardware was effectively a modified Macintosh, running a customized version of System 7.5. The Pippin lacks any standard floppy disk connector (internal or external), but it does have a proprietary PCI-based docking connector for expansion. 20
Here’s an exciting new feature for the ADB-USB Wombat input adapter: custom key mappings.
With firmware version 0.3.0 or later, you can replace the built-in mappings between USB and ADB scan codes, and create your own customized key mapping tables. Change which keys behave as Command and Option, reassign
I’m searching for a couple of guinea pigs who are interested in buying a BMOW Floppy Emu disk emulator or other BMOW hardware, and paying with Bitcoins. As an incentive, I’m offering a temporary 5% discount for anybody who pays via Bitcoin. This is an experiment into digital currency,
I’ve updated the BMOW Floppy Emu disk emulator firmware, adding new Unidisk and Smartport features for the Apple II family. After some quality hacking time with a Unidisk 3.5 drive and a logic analyzer, the hardware secrets were finally revealed! Thanks to Roger Shimada for providing the Unidisk to
The Unidisk 3.5 is an 800K floppy drive for Apple II computers, using the Smartport protocol to communicate with the Apple II. The BMOW Floppy Emu disk emulator is also capable of emulating a Smartport disk, so in theory it should be possible to plug the Emu into the
Great news for owners of the Apple II Liron disk controller card: the latest Floppy Emu disk emulator firmware adds Liron support. This means that for the first time, it’s now possible to emulate 32 MB hard disks on an Apple II+ or IIe with the Floppy Emu!
Here’s a test rig for the ADB-USB Wombat board: my first-ever project whose sole purpose is to facilitate testing of another project. It uses spring-loaded pogo pins to create a bed of nails that fit into test points on the Wombat board. I can drop a new Wombat board
The ESP8266 has exploded in popularity since its introduction a few years ago. With easy to use Arduino-compatible modules like the Wemos D1 Mini, it’s like having an Arduino that’s 5-10x faster, has 128x more memory, and has built-in WiFi, all for the ridiculously cheap price of $4. It’s
