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 some 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 sound chip (YAC512-M+YMF262-M).
- IO address selectable.
Where to buy?
In depth
Because this is effectively 3 ISA cards on one board 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 page.
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.
Schematic
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.
