I LOVE Retroshields!

Typical transputer reference designs use IMS C011 (or IMS C012) link adapter chips (from INMOS) to connect the transputer to a HOST (PC) where the iserver application downloads the boot code and afterwards provides storage/console services over the link.

Let me tell you why I did RetroShield.

If you don’t need the additional GPIO’s on Arduino Mega, you can instead use Teensy adapter for more memory and faster speeds.

8031, 8085A and 1802 RetroShields are alive now.

If you don’t need the additional GPIO’s on Arduino Mega, you can instead use Teensy adapter for more memory and faster speeds.

Well, look what I got. 3 new RetroShields for 1802, 8031, and 8085.

Once in a while, I truly come across saying great minds think a like.

Interesting article at digikey about 8-bit microcontrollers: https://www.digikey.com/en/blog/the-8-bit-microcontroller-is-still-a-great-option-for-low-power-and-ease-of-use

Updated if opengl is disabled in VcXsrv, then pcb-gtk & pcb-rnd seem to work fine.

As a use request, I brought up KIM-1 on RetroShield 6502.

Ok, this article is for those people who want to write and assemble their own assembly code, and then run it on the RetroShield.

I used many schematic capture tools but the one that always stuck with me was Concept from Cadence back in 1999-2006 (aka Allegro HDL Design Entry, example).

I don’t expect to make a living from RetroShield but this Sunday I had an unusual surge of orders.

I had a dilemna when I designed RetroShield.

At the time I was thinking about RetroShield, I read other people trying RPI as their main computer.

I’m excited to announce a very cool project for retromaniacs: A real 8 bit microprocessor connected to Arduino or Teensy Build your 8-bit microprocessor project as simple as writing Arduino Code.

6809 (Sixty-Eight-Oh-Nine) 6809 has a special place in my heart because once you read the specs, you start drooling immediately.

Ok, we connect an 8-bit microprocessor to Arduino Mega, but how does it really work?

Simon6809-Turbo is an improved version of Simon6809, so I can run FLEX 6809 operating system.

SiMon6809 is a 6809 based educational computer.
