A2USB: Apple II USB & Mouse Interface Card Emulation

What does an Apple II VGA Card, a Z80-CPM SoftCard and an USB-Apple II Mouse Interface Card have in common? Well, almost everything. All three are the same card. Same hardware. Just differing software. The magic of software-defined hardware. It can emulate many things. It just depends on software.

I started a project to add USB support to the Apple II - extending the PICO-based Apple2 VGA cards. The cards are based on excellent work by Mark Aikens, David Kuder and others. The hardware is using the surprisingly powerful and flexible PICO microcontroller. The first and most obvious application of the A2USB project is a complete Apple II Mouse Interface Card emulation, supporting a USB mouse.

The first working(-ish) homemade MMU

Back in early march, I dug out my old Apple IIe computer from my parents's garage. That was a fantastic find and I wanted to play again all those games from my childhood. Unfortunately, the computer did not power on. While searching on the internet, I was sidetracked while reading on the MMU and IOU and their lack of replacements. And then I foolishly though that attempting to re-create the MMU and the IOU with a FPGA would be a good idea. Surely, it can't be that hard...

#Apple2 #FujiNet bring-up status report 2022-01-22

Hello, everyone. 

As some of you know, I'm the public face of the #FujiNet project, which is a wireless network adapter that originally was designed for the #Atari8bit systems, and is being brought forward to more systems, including the #Apple2, with the goal of reaching every 8-bit computer and game console by the end of the decade.

It provides:

Apple I Replica

Today is possible to relive the thrills that computer geeks had back in the 70’s, when the only way to own computer was to build one, by hand, literally. One of these computers was the Apple I, the father of all, a great computer designed and hand build by the co-founder of Apple Computer, Steve Wozniak.
