Is there someone having experiences

*  using ultra-cheap programmers (like David Tait's, Henk Schaer's
  or LUDIPIPO)

*  on FAST PC's (P133...)

*  under OS/2 WARP

I already *KNOW* David's PIC84FAQ and some hints he gave there,
and the various delays in the PP.C program varieties,
and I have seen once a programmer circuit layout showing an additional
555-Timer to produce an independent timing (Steve Marchant July 96).

The use of a small timing source on the programmer sounds to me like a
good idea. Why not using one "extra" PIC for managing the programming ?
Any experiences ?

Of course, I am aware of the multi-tasking environment.

*  So, is there anyone having a kind of "PIC84 for OS2", preferably in C
  (for example using the emx compiler) and with a reliable timing
  resource on that programmer ?

Tom

The 555 is used in a voltage doubler circuit, to get over the problem
with some serial ports of a low voltage, insufficient to meet the PIC's
programming spec. It's nothing to do with the timing.
