- hmm. i haven't tried but i would suggest just using the 200 Hz timer
- counter (_hz_200) and doing calculations elsewhere... because the 200 Hz
- interrupt runs at level 6 and the longer you run at levels >= 5 (6) the
- easier you lose characters on serial ports. (receiver overrun...)
-
- just a thought :)

- PS: same goes for evnt_timer, and the keyboard/mouse/midi interrupts, etc.
- btw could this also be the cause for Thierrys modem1 devices problems?
- i think it does a few things in etv_timer too...
-
- I had the same comment. Update the counter in the 200hz interrupt, read and
- calculate during vbl, in the sleep routine, etc. I thought, way back in the
- mists of time, that I saw MiNT saving the clock value at startup, but I no
- longer see anything like that in the 1.09 or 1.10 sources. Oh well, no
- matter...
