comparison 3rdparty/utils/dladd/slow.asm @ 3206:c544854608cf
Added a couple more utilities to my utils section as well as a README.md
Added source for fast.asm and slow.asm
The fast binary strobes address $FFD9 to enable 1.79MHz mode.
This is useful for returning the system back to full speed mode after using
the slow utility.
The slow binary strobes address $FFD8 to enable 0.89MHz mode.
This utility is handy for the cases of testing some older programs for timing
that were from L1.
