ZX81/TS1000 8K ROM Upgrade

Glenn Read reviews Thomas J. Bent’s 8K ROM upgrade for the ZX81 operating system, which comes with a new 8K ROM chip and thorough documentation. New features include faster power-up initialization, automatic FAST mode for command-line entries, faster scrolling and CLS, improved tape error recovery, support for larger arrays, and tidied character set glyphs. Known bugs (LPRINT, DIVIDE) are also fixed.
