There are three test programs for\nthe lower half - `Tlower3` (runs in mode 3), `Tlower4` (runs in mode\n4) and `Tlower7` (runs in mode 7) - and three for the upper half,\nsimilarly: `Tupper3`, `Tupper4` and `Tupper7`.\n\nThe test process continues indefinitely until an error is found or you\npress BREAK. For all except `Tlower7`, you'll see stuff happening on\nscreen as the testing process proceeds.\n\n(In principle, the memory ought to behave the same regardless of mode!\nBut if your Beeb seems unreliable in some mode-dependent fashion, as\nmine does, this might help narrow things down...)\n\n# how to build\n\n## POSIX\n\nPrerequisites: Python 2.x on PATH,\n[64tass](https://sourceforge.net/projects/tass64/) on PATH\n\nRun `make` from the terminal. (To manually provide path to Python\nand/or 64tass, supply `PYTHON=xxx` and/or TASS=xxx` on the make\ncommand line.)\n\nThe output is placed in a\n[BeebLink](https://github.com/tom-seddon/beeblink) volume, `beeb/` in\nthe working copy. The output files are stored in drive 1.\n\nRun `make ssd` to produce `beeb_memory_tester.ssd`, suitable for\nwriting to a disk.\n\n# licence\n\nThe BBC Micro memory tester is free software: you can redistribute it\nand/or modify it under the terms of the GNU General Public License as\npublished by the Free Software Foundation, either version 3 of the\nLicense, or (at your option) any later version.\n\nThis program is distributed in the hope that it will be useful, but\nWITHOUT ANY WARRANTY; without even the implied warranty of\nMERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
