Hi All,

How long will it take us to get micro lisp up and running on RetroBSD and LiteBSD?

Take a look at ulisp dot com.

Pretty cool.

Lots of fun :).

LiteBSD already has a TinyScheme package:

Hi Brian,

Good point.

Actually what I was wondering was how easy is it to take some piece of code and get in running on our system. Just for fun.

I thought ulisp sounded like it might be fun and is a pretty small piece of self contained code.

I hope things are going well for you these days.

Sure--you mostly just have to write a bmake-compatible Makefile for the code and generate a control file for it (after building).

You can use any of the other ports as a template. I should write a more proper porting guide.

Hi Brian,

From where I look it seems to me that making our system easy to modify and add to is the big deal, so it can be used to do "none of the above".

I am using it to compile my stuff. Seems to work well :).

Which brings up the question of loadable kernel modules and drivers. From what I can tell that feature is not in LiteBSD? Unless I have missed something?

And does the MMU also allow the kernel space to also be 2Gbytes?

Lots of fun :).
