New beta firmware v.28 beta2 released

v.28-beta2 is a maintenance release with some improvements.

1. EPROM programming: file extensions can be in upper case
2. Changed “Logic Menu #1”: Instead sorting DS/DM logic ICs in blocks of
DS8xxx, DS9xxx, DM8xxx, DM8xxx, the sorting is now 8xxx, 9xxx without
any prefix


3. Comparison list: selected ICs from Motorola MC800-, MC900, MC2000,
MC3000-series added (equal to SN15800-, SN15900-series)

A few exotic memory ICs have been added (custom definitions):
– SY2158A, SY2158B (1k x 8 – SRAM)
– DM87S201, DM87S202, DM87S221, DM87S222 (256 x 8 – ROM)
– DM8595, DM8596 (512 x 8 – ROM)
– 74F410 (16 x 4 – SRAM)
