The user instructions of the monitor (in German) are here:
|
||||
http://www.jens-mueller.org/jkcemu/llc1.html
|
||||
|
||||
LLC2:
|
||||
The BEL character plays a short tune.
|
||||
In the monitor, it is case sensitive, most commands are uppercase,
|
||||
but some are lowercase.
|
||||
To start Basic, the command is b. To quit basic, use BYE.
|
||||
Inside Basic, it is not case-sensitive.
|
||||
|
||||
ToDo:
|
||||
- LLC1: Get good dump of monitor rom, has a number of bad bytes
|
||||
- LLC1: In Basic, pressing enter several times causes the start
|
||||
of the line to be shifted 1 or 2 characters to the right.
|
||||
- LLC1: Go command crashes
|
||||
- LLC2: Keyboard is incomplete
|
||||
- Lots of other things

LLC driver by Miodrag Milanovic
|
||||
|
||||
17/04/2009 Preliminary driver.
|
||||
|
||||
July 2012, updates by Robbbert
|
||||
|
||||
Very little info available on these computers.
|
||||
|
||||
LLC2:
|
||||
The BEL character plays a short tune.
|
||||
In the monitor, it is case sensitive, most commands are uppercase,
|
||||
but some are lowercase.
|
||||
To start Basic, the command is b. To quit basic, use BYE.
|
||||
Inside Basic, it is not case-sensitive.
|
||||
|
||||
ToDo:
|
||||
- LLC2: Keyboard is incomplete
|
||||
- Lots of other things
|
||||
