;-------------------------------------------------------------------------------------------------------- ;- ;- Name: tzfs_variales.asm ;- Created: September 2019 ;- Author(s): Philip Smart ;- Description: Sharp MZ series tzfs (tranZPUter Filing System). ;- This assembly language program is a branch from the original RFS written for the ;- MZ80A_RFS upgrade board. It is adapted to work within the similar yet different ;- environment of the tranZPUter SW which has a large RAM capacity (512K) and an ;- I/O processor in the K64F/ZPU. ;- ;- This file holds the TZFS variable definitions. ;- ;- Credits: ;- Copyright: (c) 2018-2023 Philip Smart ;- ;- History: May 2020 - Branch taken from RFS v2.0 and adapted for the tranZPUter SW. ;- July 2020 - Updates to accommodate v2.1 of the tranZPUter board. ;- Feb 2023 - TZFS now running on FusionX. Small changes to ensure compatibility. ;- ;-------------------------------------------------------------------------------------------------------- ;- This source file is free software: you can redistribute it and-or modify ;- it under the terms of the GNU General Public License as published ;- by the Free Software Foundation, either version 3 of the License, or ;- (at your option) any later version. ;- ;- This source file is distributed in the hope that it will be useful, ;- but WITHOUT ANY WARRANTY; without even the implied warranty of ;- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
