Hi @Mitsuru Yamada! Thank you for liking my #Modular Handheld Retro Computer project :)

Your PERSEUS retro computers are awesome and very stylish!

  Are you sure? yes | no

Mitsuru Yamada wrote 08/28/2023 at 03:29 • point

You're welcome. Like you, I'm also interested in a programming scale of a few KB. In the direction of the latest computer technology, it is common to generate code of megabytes or more, but I think that a single person can grasp the whole world in bits of a few KB. I want to shed light on this area that seems to have been forgotten.

  Are you sure? yes | no

Wow, you make extremely beautiful machines. Thanks for following my humble masking tape plotter project. 

  Are you sure? yes | no

Mitsuru Yamada wrote 05/13/2022 at 00:49 • point

Thanks for looking at my project too. I also like simple mechanisms. I have not written an article, but I have tried to make my own drive controller for an astronomical telescope by driving a stepper motor in microstepping, but it did not good work due to microvibrations.

Thank you for liking my project "The Talking Microtronic Computer System Emulator"!

You're welcome. I looked up the original computer training kit 'Microtronic' on a German website. In my case, the first training kit I used was Hitachi, H68/TR.

You're welcome. I'm also enjoying assembler programs on the 6502！

Wonderful!!! I would like to get any advice or suggestions from you about my project! I'm an hobbist who loves digital electronics and I have a lot to learn! Thank you also for following!

Those are beautiful projects ! Nice to see the 74141 in your Nixie Clock.

  Are you sure? yes | no

Mitsuru Yamada wrote 11/19/2021 at 14:32 • point

Thanks! SN74141 is still available, which was a big help. By the way, I used SN74142 (counter + driver) for following frequency counter in 1975.

Very nice. I inherited a bunch of 74141 produced around 1975 by Siemens and they work like a charm.

  Are you sure? yes | no
