A500 8MB IDE2

Very compact 8MB Fast RAM and BSC-AT-Bus IDE controller for Amiga 500 and Amiga 500+.

The device is based on the design by Oleg Mishin https://github.com/OlegMishin/A500_8MB_ide2. Please refer for this link for more information (manuals, downloads).

Features: (changes introduced in this version by Lotharek are in bold)

• Bootable IDE, no need for a patched scsi.device to be present in Kickstart ROM for autoboot.
• Works with Kickstart from 1.3 and above.
• Able to boot Workbench 1.3 and higher from HDD. 8MB RAM also detected in WB 1.3.
• Motorola CPU present at board in SMD package (PLCC).
• Different CPLD used, thus firmware has been reworked.
• Rotated IDE connector by 180 degrees. If SD ir CF adapter is used, it will be hanging over the expansion.
• Hybrid SMD/THT bottom socket
• Flash ROM contains BSC Oktopussy ROM and can be re-flashed on-board. 
• Works with A500 and A500+.
• The device does not work with CDTV due to DMAC on board (this can change with future firmware).
• PCB is 4 layers, HID board (high integration device) to squeeze a CPU with the PCB footprint of the original device.

Please check related products for suitable cables and adapters.

IN THE BOX

• Fully tested and assembled device.
• Please note that IDE to CF/SD adapter is not included.

Installation

• Desolder CPU from motherboard if not socketed. Solder the socket first and then install the device in it.
• if CPU is socketed, just remove the CPU and insert A500 8MB IDE2 instead.
• In both cases pay attention to pin orientation, pin 1 is at the bottom. Inserting it wrongly can damage the CPLD.
• Partition the IDE device according to manual in Downloads section above.
• Ready!
