  • Building a CP/M System Disk

  • 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...
  • Eight X Beef

  • In the latest news on the BeefyDuino frontier, my friend Ryan who is the founder of elequa, the company I am helping to start, assembled eight BeefyDuino prototypes (with a little help from his friends including me). He did this because he was going...
  • 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...
  • MIKBUG Commands

  • MIKBUG (Smithbug) has the following case-sensitive commands. ; V VIEW MEMORY; E CHANGE MEMORY; M MOVE MEMORY; I FILL MEMORY; F FIND  ; D DISASSEMBLE CODE; & S1 LOAD PROGRAMME; G GO TO PROGRAM; J JUMP TO TARGET PROGRAM ; T TRACE PROGRAM; K CONTINUE...
  • E2 Emulator

  • Sometimes, I get burned out by the hardware aspect of the project.  When this happens, I often wonder to myself, "Man, if only I had the Kestrel *finished*, then I can work on the software."  I reached that point not too long ago.So, I worked...
  • Connecting to the Arduino Pro Mini A4 and A5 I2C Pins

  • I needed to use I2C on a project with an Arduino Pro Mini, but on this model the A4 and A5 pins are 0.5in shifted and so wouldn't easily fit on a bread board without some gymnastics. I found a good way to bring them out, but it's only useful if you don't...
  • [E2][X] Plotting finger movements

  • So I spent maybe 2 hours setting up the groundwork of this excel spreadsheet and then maybe 15 minutes actually puttinging in some values. This spreadsheet assumes I'm using #Tetrescent [gd0150] and in a mirrored (aka vertical) mode where for both...
  • 20230216b -- "Files"

  • The gist of this unit is that you type text into a discrete 'file' and then you can edit and later transfer to a separate computer via the keyboard emulation.  While whizzing through the code doing other things, various strings caught my eye, such...
  • On coordinate transformations

  • The unusual geometry of plotbot means that one has to find a way to map the Cartesian coordinates of what shall be drawn to the coordinates of the steppers in a way that the tip of the triangle that is formed by the arms will follow the Cartesian coordinates...
  • 20230219c -- ROM test file

  • 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...
