Serial #000000000000000001


Thanks to the folks at OSH Park  the first production prototype has been assembled. It's quite one thing to cut the board yourself and quite another to have something so very purple and gold...

As usual, click to embiggen.


With all the handshaking issues worked out I now have a very fast and solid transfer protocol, able to load a 40K program in 300 milliseconds.

Work is now ongoing to develop the utility ROM to enable two virtual disk drives 2: and 3:. Basic support is done but I'd love to be able to boot from an SD drive. Achieving this will be a challenge if I'm to retain 100% support for the various DOS versions available for this fine machine.

Hi !

I've just acquired a tatung TC-01 :)

Is it possible to get an einSDein ?

I'm also an electronic hobbist, and I can also build one having access to your plans and fw.

Thank youy very much, and many compliments for the project !

Thanks :D

The TC01 is a beautiful machine. You shall be very happy together ;)

I will be making some einSDein boards this year. If you can contact me more directly via the stardot or sinclairzxworld forums we can talk about providing you with a kit or some plans.

Hi,

Great TC-01 addon, I found your blog when I google Tatung Hardware, for my surprise the Tatung looks abandoned :(

Are you thinking making more einSDein and sell?

Best regards
