Q&A from previous buyers:

Question: I owned 2 ltk's and was wondering if this new dos is like the original lt. kernal dos?
Answer: The RA v7.3 DOS commands are nearly identical with very few exceptions.  There are many improvements and additional functions that have been added.

Question: Can I use my turbo-232 interface with the system? Will this also work with a link-232, a cartridge expander, etc.?
Answer: The Rear Admiral Host Adaptor is equipped with an I/O port configuration jumper. You may select I/O Port 1 ($DE00-$DEFF) or I/O Port 2 ($DF00-$DFFF). This will allow compatibility with those external peripherals. The default configuration is I/O Port 2 and usually does not have to be changed unless using CP/M mode.
