  • 20230221b -- File Inserting
  • Log     from ROM Disassembly - AlphaSmart Pro
  • Intrigued by the various file-related pointers seen in deleteThisFile_EB9B, I remember that the keyboard scan routine had a final case where the bulk of the keystrokes (the printable ones) are handled, and there was a scan code to ASCII routine before...

  • Inside the TI-86
  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • Random notes, randomly updating, for now ... RAM: https://pdf1.alldatasheet.com/datasheet-pdf/view/47125/SONY/CXK581000ATM.html 128KB, has one NC pin, pin 9, so 256K in the same form-factor might be a thing, though not seen amongst the list of related...

  • Rev1 Voltage Test
  • Log     from Multimeter
  • I did another test with the rev1 prototype, this time only measuring voltage, and bringing it all the way to the maximum voltage of 60V. Again I am doing calibration and comparison to my Fluke 101 Multimeter. This has a problem as the Fluke 101 does...

  • Days 3,4,5: Eureka, sound and images found!
  • Log     from Tsukuyomi
  • 1. Toolchain not found After stepping away few days far from my PC for family reason, I resumed my activities on the Tsykuyomi project.So I started by reading the https://github.com/WHhkwong/SIPI_Bear_playback code and looking for a SNC7001A Toolchain/SDK...

  • muahaha, I cheated :)
  • 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...

  • TI-86 Logic Analysis

  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • whelp... I managed to speed up the sampling rate dramatically... My signal is /supposed/ to toggle (or not) at 8us intervals... My original sampling code took 39T-States per sample, or at 6MHz 6.5us/sample... IF I understand the z80 right... The new...

  • TI-86 LCD interfacing
  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • On the LCD board is a big TQFP that some might think to be the "LCD Controller"... That's not quite the case. That chip is a T6A40, NOT T6K04: the latter is apparently used in TI-83+ and others, and is an entirely different concept. Consider it,...

  • TI-86 Logic Analyzer
  • Log     from Vintage Z80 palmtop compy hackery (TI-86)
  • Ok, so it's gnarly-dusty and that's not real sample-data, but here goes: That's two lines of sample-data, from the link-port, wrapping, to show as much as reasonably-viewable (1024x2 Samples visible). Presently, I think each sample (pixel) is around...
