OK, I'll bite. Coldstart and warmstart are easy enough to do with a couple of SysEvals (#26775h and #267E5h respectively) but how do you set the contrast programmatically? By storing a value in a specific nibble?

To be honest, all of my 50g units are set to a perfectly acceptable contrast value after a coldstart so this is just for my personal erudition Smile FWIW I've looked through the various SysRPL and ASM documents that I have and not found anything relevant.
