  • Quick Update 03/10/22
  • Log     from UltraTower
  • Currently, I am checking the new PCB and changing the code. As soon as it's ready I'll publish it. Corrections: There were2 errors on my PCB one on the pin of the DHT22 and one on the 5V pump which consumed too much power for the 2N7000. Everything...

  • 20230219c -- ROM test file
  • Log     from ROM Disassembly - AlphaSmart Pro
  • While whizzing through the code trying to scrounge verified keyboard scan codes and flags, I found some some buried treasure in the form of an undocumented test routine.  It's not that exciting -- it just fills the current file with some sample...

  • 20230213b -- Memory
  • Log     from ROM Disassembly - AlphaSmart Pro
  • I find it vexing that I have not yet figured out the RAM banking scheme.  Some things:at reset, the peripheral configuration registers and internal RAM are mapped at 0000h.  They can be moved elsewhere, but are not.  The RAM at 40-ff is...

  • 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...

  • 20230212d -- LCD Display
  • Log     from ROM Disassembly - AlphaSmart Pro
  • The LCD is a 40x4 character display.  Judging by my friend [Eric]'s@EricHertz photos, this is not the common HD44780 device, but instead a Mitusbish M50530 I did find a datasheet for this device.  If it's not code compatible with the '44780,...
