Notes
RemarksA plug-in memory system for 48K machines and clones. Three modifications were available: 80K, 272K and 528K memory.
Jiri wrote his own ROM called LEC ROM. It fixes some well-known bugs in the original ROM, delivers a better de-tokenized BASIC editor and a few commands for copying data between RAM banks. This ROM is optional, as CP/M and custom format programs work with the original ROM as well.
This add-on came with a software tape ({CP/M 2.2 for the LEC Memory Extension|Jiri Lamac|0023809}).
