  • Vision2 - a VT100, VT102, VT220, and VT320 terminal emulator. The main reason I embarked on this project.

  • SpellMaster Spell-Master - a companion to PipeDream which would be very useful to have available at all times, without having to dedicate an entire card to it.

...

Vision's code binds its ROM banks using static addressing which fails when not running from a 32KB Eprom. Furthermore it can only run in card slots 2 or 3. It needed to have this fixed prior to inclusion in this ROM image:Vision2 Fix Patch

Likewise SpellMaster Spell-Master has two banks of ROM code but it somewhat unconventionally pages in six more banks of dictionary data. It uses static bank addressing (relative only to the current card slot) which also needed to be converted to fully relative addressing prior to inclusion: SpellMaster Spell-Master Fix Patches

XY-Modem was able to fit within some unused space in the top bank of SpellMasterSpell-Master, but it needed to be recompiled with a new org address to achieve this.

Flashing the ROM

Note

This ROM image is intended for an internal 512KB flash memory modification. It is confirmed working on a real Z88. Proceed at own risk!

ROM image for OZvm emulator:

5.0

4.7.1

Index ◇ U P D

The screen may occasionally stay off after the write to flash and the Z88 may not reset automatically.
If that happens, leave for 5 minutes to be sure it has completed, then reset manually.

< 4.7.1

RUN"ROMUPDATE.BAS" from BASIC

(the Z88 application version of RomUpdate does not work here)

Copy both romupdate.bas and romupdate.crc to RAM.
The screen will corrupt as the flash process begins. One row will blink. This is normal. Wait until complete.
