I was very out of my comfort zone doing this, but I did fix this Quicktake 150 😊

Waking up for work: tired
Waking up to see a nice article on my last project: wired 🙂

#RetroComputing #AppleII #Quicktake

Tonight I got a message from a fellow #appleII nerd, who got a #Quicktake for Christmas, tried it with his Apple II and had everything work perfect from start.
If fills me with joy, both on the software side and on the documentation side (custom cable building required! )

This week-end's release of #Quicktake for Apple II brings another 30-plus-second improvement on the Quicktake 200 decoder, down from 103 to 68 !

I am starting to be very happy with the performance of all three decoders.

I managed to get a "for parts" #Quicktake 150 for 15 euros, it only needed 15 minutes of work to "fix it" (the Trash button was stuck down). Here's its first picture!

This week-end's release of #Quicktake for Apple II brings the decoding speed to under 60 seconds for Quicktake 150 pictures.

6502 optimisation challenge anyone?
This is one of the two longest functions in my #Quicktake 150 decoder, it's called 110k times, takes 7.9M cycles.
The vars are in zero-page already.

The function reads bits from a buffer to get the next valid Huffman code out of the buffer and return its value.

I'm out of ideas :)

Edit: Reading multiple bits using a lookup table will not be better, as it requires a 16-bits buffer which is extremely slower to asl/rol. It was the previous implementation.

The function:
