Personalia
An Apple Enthousiast since 1983 when we first obtained a bare Apple II logic board for which we (me and my dad) created a custom case. At the top of my collection I had several Apple ]['s and ///'s, a whole bunch of interface cards, several ProFiles and meters of software. Unfortunately this has been given to others in the past.
Currently I have a few (obtained a few years back) IIgs's, 3 working //c's and a Macintosh Colour Classic.
Right now I am working at a school in The Netherlands as ICT Coordinator.
Projects
The Apple II is a renewed hobby of mine and I have set my self to the following projects
Apple ][ Slot connector symbol and footprints I designed for Kicad and Eagle

- I created these as I started my first projects with designing some boards for the Apple

Apple ][ Multi Media Card (MMC) Mass Storage card
Status
- active
Description
- Board - Preliminary board design is done and a few bare boards have been ordered.
- CPLD - CPLD implementation is incomplete, I still lack some knowledge of VHDL to get some basic signals to work. The CPLD I use, is the Xilinx XC9572XL, as that is a 3.3V CPLD, but with 5V tolerant inputs.
- ROM - A basic ROM has been had working with a breadboard like environment.
My goal is to create an expansion card which uses the Multi Media Card SPI interface, based on the SPI65/B by André Fachat
(which in turn is a VHDL reimplementation of Daryl Rictor's 65SPI) as a (raw) mass storage device.
Current Issues
- The biggest issue I still encounter is that I can't get the basic control signals from the slot put into the correct VHDL code in my CPLD project. These signals I have to process are e.g. /IOSEL, /DEVSEL and /IOSTROBE.
- I will try to add the schematic representation to this page when I have it recreated.

- On hold
Description
- At the moment this project has halted as I am trying to understand how to make "shell-like" models/objects this small using the 3D-printers we have at our school.
