The A500 IDE / 8MB Fast RAM Module is the perfect addition to any Amiga 500. This module provides your Motorola 68K with 8MB of Fast RAM while at the same time allowing you to also add a hard drive so that you can install and boot from WorkBench.
Features:
- IDE Controller – Mini IDE to support compact flash and SD to IDE adapters
- 8MB Fast RAM
- Compact All-in-One design
- 4 Layer Board
- Hand Solderable 1206 component sizes
- Support for ATF1508 / ATF1504 TQFP100 CPLD’s
- Tag Connect JTAG for easy Firmware loading
Some things to note:
- To boot via IDE, you’ll need to either patch your Kickstart ROM or use a Kickstart ROM that has the required SCSI drivers such as Kickstart 3.1
- 2 points at the expansion port will need to be soldered /OVR and /INT2. Documentation is available below
- Due to the limited I/O on the ATF1504, CFGIN / CFGOUT is not implemented
This project was inspired by Oleg Mishin. You can find the original project here.

Where can I get the source files for this hardware?
The original hardware was GPL 3.0 so this modified version should be covered by the same principles.

Sure, not much was changed, just enough to adapt it to work with the 1504AS.
This is the source for the CPLD
