  • What to do... Hmmm?

  • I sat around thinking about what I useful thing I could build in one square inch of PCB, I decided on something with blinky lights or a display. Further refining the idea, I settled on a minimalist display for a Raspberry Pi.Hmmm, this might just work....
  • 16-bit Dividing

  • I've been programming furiously.  I have 16-bit functions going - Add, Subtract, and Divide.  And I have 8-bit multiply going.  I've changed from putting the operands on the stack to having a dedicated memory location for them.  I...
  • Gradatim Ferociter

  • Step by step...I'm quite advanced now with the soldering of the boards. However I'd like to test the multiplexing of them.First I start to think how mount everything on the screen back :It fits very sharp on the diagonal.I decided to switch to a smaller...
  • single FPGA slice (without routing)

  • I felt like building an FPGA slice, so I did.Based somewhat upon Nick's Blog entry here.Sorry for the bad photo, my phone has issues.  Essentially the bottom three ICs are 74hc595 (CMOS logic levels) for allowing an arduino to program...
  • A ZX81 in TTL chips

  • One can add slow mode hardware to a ZX80, but I decided to buy a board with this designed in already. 2023-08-19 I bought these boards on eBay. The logic board has some nice features. The bus signals are available on a holes for a header,  allowing...
  • Internet

  • This was always a stretch goal, but it looks very doable now the design is complete... and it wouldn't be the first TTL Computer on the Internet. What is the scope of Internet-enabled? Connectivity is via the RS232 port. This provides an ancient but...
  • Connecting GPS sensor to Pi Zero

  • There are many tutorials on connecting GPS to a Raspberry Pi available online so I followed some of them to connect a GPS sensor I had laying around to the Pi Zero. The best resource I found for this was https://learn.adafruit.com/adafruit-ultimate-gps-on-the-raspberry-pi...
  • Research

  • One of the first parts in technical papers is a survey of existing works.  Z8000 board (the Trump Card) by Steve Ciarcia in Byte magazine Hardware: A full-length ISA board as a slave to the PC. Most of it is a massive array of sixty-four 4164 DRAM...
  • The Microcontroller

  • The hardware is rather simplistic. It consists mainly of 4 LEDs and tactile switches surrounding the MCU. Lets have a look at the chip itself. The chip itself is part of chinese STCmicro line of 8051 derivative MCUs. It sports a 1T architecture compared...
  • USB

  • One of the final things missing from the Yellow MSX series of kits for the RC2014, is the ability to access typical MSX storage devices (floppy and cassette). Without storage such as this, its hard to claim that we have achieved full MSX compatibility....
