  • ALU and Instruction Set

  • Hardware testing is complete on all the jump and branch instructions. So that's the first 8 out of 256 instructions tested! The next 24 are loading operands. These should work fine since the jump/branch instructions are also loading operands in order...
  • Multi-boot Multicomp (Part 2)

  • I've got the BIOS loading for Multi-boot Multicomp. It boots up to the Multi-boot prompt. > Available Commands: :ccxxxxiibbbbbb Load Intel-Hex file record Rxxxx Run from address xxxx Sddd System boot Iddd Init: Format directory Pddd[,xxxx] PutSys: write...
  • The Keyboard

  • Before I start this log on the keyboard I should mention that I'm in the process of putting all of my writings and software on the Video Writer on a small website. The following is an almost direct copy of what will be the article about the keyboard......
  • 10/8/23 Update

  • Here are some "Quickstart" instructions for the Menu, BASIC, VTL2, and Visual/02 programs in Mike Riley's alternate program ROM. They're not a full manual yet, but will get you started and give you a "taste" of vintage programs and languages. A Quickstart...
  • 20230221b -- File Inserting

  • 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...
  • Cyrillic alphabets in Terminal-BASIC output

  • My friend Dylan Brophy inspired me to investigate the ability to output the cyrillic text using different output devices, supported by Terminal-BASIC. 1. Using symbols others then capital latin in identifiers not possible and unnecessary. 2. USART output....
  • ACPI is working now

  • At last, I found a bit in EC RAM that is used to enable EC ACPI, so ACPI is working now. I copied the ASL code from vendor DSDT, and now battery, AC, and lid status change can be detected by OS now.https://review.coreboot.org/#/c/19072/
  • 20230214a -- Memory, cont.

  • 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...
  • Peak Performance

  • Below is a picture of a patch that gates the input to the ADC so that it is only looking at the value from the EC probe at the end of the square wave pulse, after the initial transient has settled out. It works really well, dutifully recording the voltage...
  • B1+B2 completed. Also, facing my first real problems.

  • Finally, B1 and B2 are completed and they.... kinda work... Although I'm going to have to check quite a few things.Remember how B0 performed flawlessly, both when connected via the expansion port, and when replacing CIA#2? Well, that's no longer true....
