KiwiSinceBirth has updated his compilable source for the Model I. It is compilable with Telemark Assembler includes v1.2, v1.3, and EACA (selectable by #DEFINES). The following customizations are included:
- Enables the FreHD auto boot feature, i.e. the Auto boot ROM.
- Disable the use of memory mapped hardware at 37Exh, Floppy disk, Printer, etc. for machines where these peripherals are not needed (e.g. in a FreHD only system) and allows the use of the 2kb memory 3000h – 37FFh
- Set NMI (reset) as always perform a hard reset instead of returning to READY on non-DOS systems
- Disable Alpha character translation of letters A-Z,a-z to the values on range 00h to 1Fh. This is useful when a lower case mod is installed, but an alternate video driver has not been installed, or where the font rom on the machine has the alternate characters in the 00h 1Fh range (0471h)
