I've been busy porting the recently posted (comp.sources.unix) SC Spreadsheet Calculator to Minix. The port is not yet finished and I'm not sure if I'm ever going to finish it as I only want to see whether it is possible to port it to SparcStation Minix. A few problems showed up. First, SC uses floating point. Minix-SPARC supports floating point on the C level. That means, that you can add, subtract, multiply and divide floats and doubles. I can even convert them to and from integers and print them. Aside from the sin() and cos(), Minix does not provide other FP functions, so I've commented out those special spreadsheet functions, that use them. SC uses curses routines for in/output to the terminal. I used the recently posted curses functions from Bjorn Larsson (posted by Don Cope). Those functions are developed on a PC and that shows! I had to modify quite some functions, which handle screen attributes and ioctl()'s. Currently, SC works under Minix-SPARC (without @exp(), @floor(), etc). The curses functions are still buggy, so they should be polished up. It's quite a nice spreadsheet, not the extensive features of 123 or Excel, but still very usable under a multitasking OS like Minix!

I have a copy of the BSD curses source code.

Unfortunately, I don't have the time to take on anything like that now.
However, I would be curious to see it. Could you perhaps tell me where
in the BSD distribution that source was?? Then when I have the time, I
could look it up on UUNET.
