Intro

This project started off with my Toshiba collection, Many of these early Toshiba T-Series have an expansion slot in the back. Looking through the maintenance manual's for these Toshiba's I found out that they just used the ISA bus with a different connector and formfactor for the expansion slot.

I already had some of Lo-tech's XT-CF cards and wanted something similar for the Toshiba slot. Therefore this card is based entirely on Lo-tech's design, I used the schematics on his website with some small changes, Of course I asked James if he was cool with that.

Features

The card has an easily accessible CF card slot. which allows you to expand upgrade or replace the storage of your Toshiba portable up to 8.2GB.

The XT-ide BIOS on the card allows booting from the CF card.

On Toshiba portables with an internal IDE controller the BIOS on this card can also be configured to control the internal IDE controller. This allows you to both use the CF card slot and/or replace the internal drive with any standard IDE drive.

Compatible Toshiba models

This card is compatible with every Toshiba model that has the expansion slot, or as it is named in the official Toshiba documentation "Toshiba proprietary expansion slot - "A" form factor".

  • 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.
