In Topic: SpartaDOS X date & time

Yesterday, 12:04 PM

What you need is described in section 6.8 of the current SDX User Manual (Page Seven "Kernel" Values).
 

date $77B see below (3 bytes)
time $77E see below (3 bytes)

The 'kernel' routine is called by doing a jump subroutine (JSR) to address $703 with the
desired command in the 6502 Y register and the desired device number previously
stored in the memory location 'device'. For example, with a $10 in device, a value of 100
in the Y-register will cause the current time and date to be placed in the variables 'time'
and 'date'. A 101 will cause the current time to be set to the values contained in the
variables 'time' and 'date'.

kd_gettd 100 get current time and date
kd_settd 101 set time and date

@flashjazzcat decided to try his hand at a pair of replacement routines for mul0625 (for X) and mul0375 (for Y), which do the coordinate transformations to and from PLATO space, and it looks better! :)
 
Thanks, Jon!
 
So I've attached a build here:

Wow... That was quick! Glad it works.

Yep: the manner in which the all-knowing one imparts his wisdom leaves much to be desired.

Works, and the awful pop-up window has disappeared as well.

another dose of disinformation :-)


My apologies. I must have imagined the amount of hassle which surrounded it at the time.

All's good, then. :)
