1st step:
Use 1mm drill bit to widen the plastic case of IDC connector.
But very carefully with gentle force inorder not to damage the inner metal clamp of IDC
.
2nd step:
Push the spring connector pins one by one straightly against a semi hard surface (wood, etc) one by one.
The inner clamp is not designed for 1mm,
İt will clamp the pin tightly, no chance to pull back the pin again!
Must be done correctly at first try!

You ought to be able to program 8k bytes in just over a quarter of a second (8k bytes of flash x 4 bytes per programming instruction x 8 bits per byte x 1us per bit). Doing and undoing a clamp will be much slower than that.
I have realised that I have a jumper on my USBasp ( http://msx-elektronika.pl/en/usb... ) and it is on "slow", however, I remember putting it on due to the fact that it did not work on "fast", does any of you know what could be the problem?
Is this the problem of having an internal CLK on 1Mhz / 8Mhz, is this the source of a problem for programming at higher speed?
What's the secret?

True for second step!

TopI do not why, but it takes me around 30sec to program good 4kb via usbasp...
Best.
Bravo!!!
