RTC ISA 8 bits (Very Low Profile)

I wanted to store the date and time on the IBM XT 5160, and thus i stumbled upon a great project on Tindie.

For a small card it's a fun thing to solder together and get working. But it needs some explaination if you want to use it on a XT.

Take a look onto the github page of spark2k06 the creator of the card.

The software i use you can find here: RTC.zip

I'm using the following in the Autoexec.bat:

c:\rtc\get_rtc 576

Where as the 576 stands for: port 240h
