This repository contains circuit diagrams, PCB data, and documentation for a power supply adapter that allows a Corsair SF450 SFX unit to be used with the FM TOWNS II HR. The adapter includes a control circuit (NE555 + 74HC132 + 74HC74) so that the original power and off switches

This repository contains circuit diagrams, PCB data, and documentation for a power supply adapter that allows a Corsair SF450 SFX unit to be used with the FM TOWNS II HR. The adapter includes a control circuit (NE555 + 74HC132 + 74HC74) so that the original power and off switches on the FM TOWNS II HR continue to work via PS_ON# control.

このリポジトリは、Corsair SF450 SFX 電源ユニットを FM TOWNS II HR に流用するための 変換アダプタの回路図・PCB データ・ドキュメントをまとめたものです。 NE555 + 74HC132 + 74HC74 による制御回路を搭載し、FM TOWNS II HR 本体の 電源スイッチ・OFF スイッチを PS_ON# 制御で引き続き使えるようにしています。
