I tryed to use an Pentium 1, 133MHz to progrm the GP300 radio with, but when I shall read the codeplug I get error 2, its working whit older maskins like 286 but not whit my Pentium 133MHz! Can somone help me?

A P133 is in all probability too fast for a DOS-based Motorola RSS. Stick with a 486 or, even better, nothing faster than an old 386 for your GP300 programming. Another problem could be that you THINK you're running DOS but you're actually running a "fake" DOS which runs under Windows; that type of DOS will NOT work properly with your RSS either, so you may have two problems actually, one involving the speed and the other involving the improper DOS running under Windows.

Use a 286, or 386 and you will have no problems. Even an 8086 or 8088 will work, but they take forever to execute.

Tom is right..A pentium/586 is too fast! The big "M" like too keep up there minefield!

I use a Pentium 166 to programm GP300's with out any problems..BUT I make sure I am in REAL DOS not the "dam---" Windows' crap so called DOS. If in doubt, boot to DOS 6,xx from a floppy disk and try the RSS. This is the most often RSS failure.
Another problem is some newer computers have FIFO buffers on the serial port that some versions of RSS does not like. Sometimes you can turn off the FIFO in the computers' setup.
Here again as the newer versions of the RSS are updated, (read pirate proffed) they are made to deal with the timing problems of serial ports on the faster computers.

We've found that running cheap (as opposed to "inexpensive") pentiums with VERY slow buss speeds is a key point. Our primary PC is a 233MHz, but the buss is probably 50MHz (now you know why Packard Bell/NEC is out of the PC business).

Under all circumstances, as everyone else has stated, you must run in real DOS.

I regularly use a 150 Pentium with no problems. Once in a blue moon, I use my 533 desktop and it works just fine on the GP300s.
Boot up with DOS floppies.
