3inONEder for Toshiba portables

Intro

This project started as a continuation of my previous CF adapter for Toshiba portables project. In using those I started to realize that there where more features that I wanted on my Toshiba's, like sound and analog joystick controls. Unfortunately most of the Toshiba models only have one expansion port (except T3200 & T5200 line). So it quickly became clear I had to integrate more features on the same boards.

Features

• Compact Flash adapter, bootable using the XTide BIOS
  • Bootable or as second drive.
  • Reconfigurable XTide BIOS from DOS.
  • Ability to control Internal IDE controllers as well.
• PC Joystick port.
  • Connect one or two joysticks for a total of 4 analog inputs and 4 buttons.
  • Compatible with 4 button joysticks/gamepads like the Gravis Gamepad
• Adlib compatible soundcard
  • Yamaha OPL3 soundchip (YAC512-M+YMF262-M).
  • IO address selectable.

In depth

Because of the fact that this is effectively 3 ISA cards in one I'll split this part up in 3 different sections

CF adapter

Based on Lo-tech's XT-CF cards

This is the same design used in my previous "CF adapter", I will not copy all info over to this page, so for info (and programming) on the CF adapter portion please refer back to that.

Soundcard

The soundcard portion is a copy of Texelec's excellent Resound 2card.

I made some small changes to allow for IO address selection based on "spark2k06" Internal OPL3 board.

Joystick adapter

The joystick portion is schematically the same as IBM's Game Control Adapter. I did only use SMD parts instead of TRH for the board layout to save space.
