  • Log     from Fluke 8060a Custom LCD
  • Dave at eevblog posted an excellent video series on designing custom LCDs, so I watched those a number of times.  I also found another eevblog user who posted a great writeup of a replacement LCD he designed for his Tandy/Radio Shack TRS-80...

  • 20230214a -- Memory, cont.
  • Log     from ROM Disassembly - AlphaSmart Pro
  • Operating under the current assumption that RAM is 32 KiB banked at address 0000-7fff, with the first 256 bytes masked off by special function registers and internal SRAM, some other code sections of interest were found.  E.g.:ED00 loc_ED00: ED00...

  • OPS ENUMERATED - Draft
  • Log     from TIS-100 (Geiger)
  • This represents a complete OPCODE list with 14 Constants (int values) available and 10 Labels (byte values) available for creating subroutines. Constants were favored over Labels, but this is up for evaluation. NOP and HCF were both added to the official...

  • Details     from YGREC8
  • After the explorations with #YGREC-РЭС15-bis, I reached several limits and I decided to scale it down as much as possible. And this one will be implemented both with relays and VHDL, since the YGREC8 is a great replacement for Microchip's PICs....
