ReActiveMicro Drive/Turbo – II, II+, and IIe Firmware
This is the II, II+, and IIe firmware for the MicroDrive/Turbo IDE Controller. It can work with a 6502 or 65C02 CPU, enhanced or unenhanced IIe.
You will need a special tool (or paperclip/small screwdriver) to remove the ROM (upper right on the pic). Although possible to use the II firmware in both the II’s and IIgs we would recommend a separate Turbo for each (discount available for more than one board) as the IIgs firmware is MUCH faster. The II firmware however allows for more flexibility – if needed.
NOTE: If you bought your MicroDrive/Turbo or firmware upgrade BEFORE September, 2019 then you can benefit from this update if you want to use your card in a II, II+, or unenhanced IIe. If you have access to an IC Programmer you can also burn your own ROM. Visit the RM Wiki page for the new firmware file.
