3inONEder for Toshiba portables

File:3inONEder T3100sx.jpg

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?

Unfortunately all expansion cards are sold out at the moment. More will be listed soon on my eBay account.

Update: Due to the global pandemic I am having trouble sourcing all of the components. A small batch of about 35 card will be listed on my eBay page on Friday 02/09/22.

Compatible Toshiba models

This card is compatible with every Toshiba model that has the Toshiba expansion slot, or as it is named in the official Toshiba documentation "Toshiba proprietary expansion slot - "A" form factor". The expansion slot is located on the back of the machine, only the T1600 has it on the left side.

• T1100 PLUS  (not T1100)
• T1200
• T1600
• T2100 from 1986 (not the later "satellite T2100")
• T3100 (E)(sx)
• T3200sx(c)   (not T3200)
• T5100
• T5200(c)

Some of the Japanese models J-3100… have the same expansion slot and should work as well, not sure. I have not been able to test this yet however.

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.

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.
