ROM checksum code
Log from Re-UD-80 - a larger display for Epson PX-4 / PX-8
The 5.21E ROM works file with the current board, but the 7.11A ROM uses a different pin for the vertical sync signal. This can be fixed, but then the 5.21E ROM results in no display. Rather than fixing the hardware (with a jumper to be changed when the...

Log from Game Boy Cartridge plus Programmer
So since the Teensy++ 2.0 bootloader is not available and I'm not feeling comfortable to learn all the bells and whistles of USB communications I was looking for other options. Googling "at90usb1287 arduino" I found this https://github.com/mattairtech/ArduinoCore-avr...

Micro-coded controller deep-dive
Log from Custom circuit testing using Intel HEX files
In this project, instead of using a standard embedded processor and programming it to execute 3 tasks at hand (parsing HEX character stream, generating HEX character stream, and writing character stream to video RAM driving VGA), I created 3 independent...

We Have Blinkenlights!
Log from 2:5 Scale KENBAK-1 Personal Computer Reproduction
With the wiring complete I wrote a small program in Python to test the lights, buttons, and switches on the front panel. To be clear this is NOT the KENBAK-2/5 emulator running a program (yet). As it turns out I did have to replace one of the LEDs...

The Great Resistor
Details from The Great Resistor
This idea was born when i saw this project years ago: https://hackaday.io/project/170961-resistor-color-code-clock-v10 NOTE: There is a bug showing resistor values under 100 since gold nor silver can be displayed. AND the multiplier seems to be...

side quest: temperature measurement
Log from automated gardening - reservoir infrastructure
I must confess I haven't spent much time looking at NTC curves before. My prior knowledge was that they are somewhat ill-defined and can only deliver reliable measurements when calibrated individually. source: https://support.belimo.us/Documentation/Standards-Compliance/957165601/What-is-the-difference-between-NTC-10K-Type-2-and-Type-3-sensors.htm...

Building a CP/M System Disk
Log from My CP/M Single Board Computer
Building a CP/M System Disk To avoid rewriting the assembler codes for ccp, bdos and cbios so that they can co-exist in the same file. I can append the i8hex files and remove the "end of file markers". To make the hex file more readable I have changed...

I might be missing a few connections yet which I'll correct as I come across them, but here is the pinout of the XC3S250E FPGA on the control board. Note that the SRAM and the Flash share an interface bus. Also note that the JTAG interface...
