It is possible to replace all the batteries with modern cells, for example here are AA rechargeable batteries place in the original casing by the previous owner of the machine:

Hard Drive

The original T1200XE contained 20MB JVC HDD, which configuration was hard coded in BIOS. This HDD comes from T1200XE-40 version, that was upgraded to 40MB JDE2850P30-2 HDD. I noticed two versions of the BIOS (written on EPROM). Version 083A seems to support 20MB drive and version 083B supports 40MB drive.

The drive can be replaced with a modern Compact Flash to IDE adapter. I have not tried to make it boot, it probably requires installation of a solution like ANYDRIVE.

Floppy Disk Drive

2MB Matsushita ZA0856P01 EME263-TL. It is a really problematic drive with its rubber belt propelling the disk rotation. The belt dissolves with time. It can be replaced with a new belt, I fortunately had some belt that just fit, but I don’t know the exact parameters needed.

Power Supply

Briefcase

I am not sure if this bag is 100% accurate for this model, but it is Toshiba, it is retro and works well and look great here.

  1. Did this machine have the blinking red LED issue ? I see the caps on the power board are all new and modern and not the original caps.

  2. I’ve not had sucess recapping the power boards on these, of the 2 I’ve attempted to recap they still had the blinking red led problem. Not sure if those small caps the bottom main logic board also need replacing, as I usually skip the smaller ones.
    The power board was soaked in old electrolite and stunk my house out, smelt awful for weeks 🙂

    1. I think I remember that I powered it on by connecting regulated power supply to the battery terminals. Possibly there were problems with powering it on through the normal PSU and I didn’t know if it was because of missing battery. But I don’t remember if it was the red led blinking.

  3. Thanks for all the info and photos! I’m in the process of dissasembling a 1200XE at the moment with the help of your excellent photos. How did you remove the small plastic cover over the screen hinge with TOSHIBA logo stamped on it ?
    I don’t want to break anything and it looks like it should just clip off to access the the screws behind it.

  4. This was the first laptop I ever owned. It was old and mostly obsolete by then, but I did a lot of work with it and it changed my life. Nice little machine for its time.

  5. I have a working T1200HB en route to me this week it seems to be somewhat different to the XE. Do you know anything about the memory expansions for these devices? I have spent days searching but can’t find anything more than part numbers.
