- ebay - bare PCB $8
- Arrived in a couple of days
Build Notes
- An Easy to Build Real Homemade Computer: Z80-MBC2! - Instructable was helpful
- Hackaday project with files
- Used mostly junk box parts
- Purchased alternate SRAM
- Forgot to buy SIP resistors - made my own
- Ref des are not top-bottom or left-right
- PDF Assembly drawing text is not searchable
- Struggled to find some of the resistors
- KiCad Gerbers
Programming THE ATMEGA32
- Was able to use ATProgHead running Arduino as ISP to burn bootloader but not program the code
- Could not use any of my FTDI cards fir serial programming since the have RTS/CTS but not DTR
- Most programmer setups in Arduino work just fine for serial, but not the
- Used TL866ii to program ATMEGA32 fuses
- Reference: Setting AVR Fuse Bits
- If you use the programmer defaults it sets the clock to 1 MHz which gives a serial port rate of 600 baud (told me I needed to fix the fuses).
