Commodore 1551 disk drive CPU & TRI-port replacer 6510T 6523
MCes Oct 17,2026
This plug board fit into the CPU 6510T and TRIPORT 6523A (or 6525A) sockets replacing their functions inside the 1551 drive.It can be very useful if one of this very rare and expensive chip is not working.(The other original chip can be sold to save a part of the cost..... )The new CPU and VIAs are generic chips (not custom) and they are more common and more cheap than original,so if you will have the necessity to replace them it will be simple and not expensive.https://www.amibay.com/threads/co...

Amiga Floppy to PC Floppy Drive Adapter
Sep 16,2026
The AmigaPCDriveAdapter is a small two-layer interface board that sits between an ordinary PC 3.5" floppy drive and an Amiga's original floppy cable, translating the signals the Amiga expects. It mounts internally, directly onto the drive's 34-pin header, so no case modification is needed. The design is built around a single 74LS38 open-collector quad NAND plus a handful of passives — no firmware, no programmable logic, nothing to flash.This is simply a share of an existing open-source project. ...
