General

  • Added a popup window when loading a binary file and at the same time an address is specified in the 'load' field. The popup will give the option to select either a load at the specified address or at 0.
  • Fixed a bug in loading of binary files for computer emulations that used the extended load GUI
  • Corrected handling of 'illegal instruction' 68 in CPU 1802 mode; i.e. as an INP 0
  • Added menu item 'Settings/Startup Value' to define initial CPU Register, RAM and Video RAM values. Options for CPU Register are zero or random, for RAM/Video RAM zero, random and dynamic. Dynamic is mimicking the COMX dynamic RAM pattern
  • Fixed support for Windows 2000 (use XP package)
  • Fixed crash on 'Function and Hot Keys'

Debugger

  • Added support for Memory Dump of intel 8275 Video RAM and 1870 Colour RAM
  • Added support for COMX SB Eprom Bank switching in Memory Dump
  • Fixed a bug in the direct assembler which caused some Chip 8 code to show up on machines not actually running chip 8.
  • Corrected updates of Direct Assembler data fields if changed in real time by the emulated computer

Help

  • Updated / corrected help for all added features

Video Terminal

  • Correct bug in timing VT
  • For Cosmac Elf, Netronics Elf II, Quest Super Elf: Added VT 'Ajust baud rate' option which should be selected when using Mini and Super Gold Monitor programs as they use slighly different VT timing
  • Corrected saving of VT speed in configuration for Cosmicos
  • Correct bug when setting default configuration where VT speed was not shown correctly
  • Corrected bug when using 7 bits
  • Corrected bug when using parity bit
  • Corrected bug in setting VT configuration correctly after use of VT Setup.
  • Added option to select bell frequency or wav file

Cosmac Elf, Netronics Elf II, Quest Super Elf

  • Added RCABug.hex file in the package
  • Corrected mapping / ghosting when using giantboard

Netronics Elf II

  • Corrected RAM mapping / ghosting, i.e. only when 256 bytes RAM option is used

Membership Card

  • Added support for Chuck's monitor program including binary and hex files for version 1.5
  • Chuck's monitor set as default
  • Correct bug in loading non-volitile RAM
  • Changed led output to OUT 4
  • Changed switch input to INP 4
  • Added 2 memory configurations to handle 32K ROM - 32K RAM and 32K RAM - 32K ROM (i.e. either ROM/RAM starting at 0 or at @8000)
  • Added possibility to save and load filed from/to the VT (for use in L, S, I and C commands of Chuck's monitor
  • Corrected I/O handling (INP/OUT 4, 5, 6 and 7 the same and 1, 2, 3 input 69h, 6Ah and 6Bh)
  • Added I/O selection on N0, N1 or N2 with N2 being the default setting
  • Added support for red/green Q led
  • Added configuration and files for Richard's Bascomm3
