[TheHighNibble]

October 2022 Release

https://github.com/thehighnibble/firmware/releases/tag/v1.10.0

This is a minor release that:

• includes firmware for both the IMSAI8080 (imsaisim) and the Cromemco Z-1 (cromemcosim) from Z80PACK
• is based on the development branch on the Z80PACK GitHub repo.
• updates the desktop UI (webfrontend) to a unified codebase that supports both machines
• as this is a minor release this
  • introduces breaking changes
  • requires manual updates to the image on the µSD card for an existing IMSAI8080esp system (updating from v1.9.1)

It is recommended that the IMAGE for this release is loaded on to a new µSD card and any disk images and required configuration is transferred across from the old µSD card

See the release notes for more details.

If upgrading an existing IMSAI 8080 install please read the release notes carefully and follow the directions repeated here:

IMAGE

The IMAGE package is a ZIP file of the complete contents of the microSD card and can simply be unzipped onto a newly formatted (FAT32) microSD card with a capacity of 128MB or greater.

It is recommended that the IMAGE for this release is loaded on to a new µSD card and any disk images and required configuration is transferred across from the old µSD card

If upgrading from an earlier release of the IMSAI8080esp firmware, the following manual changes need to be made to the content on an existing µSD card image to make it compatible with this firmware release v1.10.0. Failure to make these changes may result in a machine that won't boot, or continually reboots

• create a folder /imsai/roms
• create a folder /imsai/tapes
• copy all files /imsai/*.hex to /imsai/roms/
• copy the file /imsai/roms/viofm1.hex from the IMAGE.zip file (...) to the same place on your µSD card.
• edit the file /imsai/conf/system.conf to include the memory configuration sections eg. [MEMORY 1] onwards in the same file from IMAGE.zip (...)
