Hi all,

I've been scouring the internet since I ended up with a Toshiba T-100. It's a pretty nice little machine, really, but there's not a lot of usable information online about it. Maybe it didn't sell well here in the USA?

Anyway, I'm looking for information - programming manuals (especially T-BASIC 1.1), owners manuals, anything really about the T-100. I've found some info on the Pasopia, but translating computer commands and uses isn't working out well.

I only have the base unit, no dual disk drive box, or any cables. I'm using the B&W RCA composite out for now, which is fine. I've found some pinouts as well - for the Pasopia - which has different connectors on the back.

I'm using an emulator to try and get the hang of things, but I can't seem to get the disk drive options to work correctly. Seems that OA-BASIC has a 'disk' version and so does T-BASIC.
Somehow the emulator doesn't see the drive as connected, and it's the same on the actual machine as far as errors go. Maybe there's a hardware connection when the drives are plugged in to show that they're present.

I'm also including the best picture I could find of a complete setup. I'm not particularly worried about the monitor, but the drive box would be nice!

Any help would be great!

Thanks!

I'm also considering dumping the ROMS in it, but I've never done that before - so any tips there would be appreciated!

These chips look like 64kbit roms (the 64 in the part number). So i would try to read them as for example a "AM27C64" chip in my software.
I use one of those "tl866ii plus" programmers.
Factory ROMS often have strange partnumbers but work pretty much like a regular EPROM if you want to read them.
In the end you should have 4 8kbyte .bin files. Give the dumps proper names so you know wich content belongs to wich rom.

Thats all the tips i have 😁 . Maybe it helps.

Edit: To see if your read content is good, you can write a EPROM (27c64 type) with your content and see if it still works...

Thanks! That's the kind of info I'm looking for!

There's also another ROM in there, TMM334P, same amount of pins.

I'll look into the programmer and see what I can come up with!

Thats a 2kbyte (16kbit) ROM. That should be a 27c16 type.
I had to look up this type but i found a nice PDF with the sizes and types some Toshiba Mask Roms.
https://datasheet.datasheetarchive.com/origin … 12010006539.pdf

My programmer offers me for example a Fairchild Part (NM27c16) ... That should work to read your MASKROM.

I've just uploaded the English T-100 Owner's Manual with Floppy instructions, and the Programmer's Reference Manual to the Internet Archive:

Happy computing!

There is another Owner's Manual posted with a section for the monitor with some good info like monitor pinout conversion to IBM, etc.

There's a Technical Reference Manual:

And also a maintenance manual:

Now there seems to be a decent amount of information online!
