Without the MAF, the engine will be unable to adapt to the conditions the sensors sense and will have to run on defaults. Sometimes rich, sometimes lean. Running for a short time to diagnose the MAF is common but I wouldn't do it for long as you risk the expensive cats. I'd presume you have checked for air leaks and pulled the codes to see what the ECU thinks are the problems.

Is it OK to drive my 1999 Boxster with MAF cable disconnected. It ws misfiring a lot. Stopped completely when I disconnected.

Is your check engine light flashing?

If yes, then you should not drive the car until the problem is fixed. Continuing to drive the car with a flashing CEL WILL damage the catalytic converters.
