Apple ][ QuickTake 150 hack!

This looks pretty cool!

Optimizing A QuickTake Image Decoder For The Apple II’s 6502

The idea of using the Apple II home computer for digital photography purposes may seem somewhat daft considering that this is not a purpose that they were ever designed for, yet this is the goal th…

I'm a bit surprised he seemingly wanted to take QT image files and then convert those rather than take serial input from the QT150. And I thought that the serial data format for the QT series had been reverse engineered. Am I wrong here?

Seemingly not. The same person also reverse engineered the QT100 serial format, which works for a 150 and 200.

Quicktake for Apple II

Quicktake for Apple II is a program to fetch and view your Quicktake pictures on your Apple II. Reject planned obsolescence!

A third document documents the protocol itself:

Finally, a Java app which can talk to a QuickTake camera:

Hi! Author here
Well, the serial input gives us QTK image files, so both are necessary. First get the QTK image from the camera over serial, then decode it.

And I thought that the serial data format for the QT series had been reverse engineered. Am I wrong here?

It has been indeed

Seemingly not. The same person also reverse engineered the QT100 serial format, which works for a 150 and 200.

To be precise, the 100 and 150 share the same serial protocol, the 200 is a different one. I reverse engineered the 1x0 protocol, but for the 200, someone else (Pierre Dandumont) had already done it.

Great to hear from the author!

I have a QT150. I think either @cheesestraws or @Durosity do too, because they were recapping one recently. Interestingly, the inside of a QT150 is bigger than the outside.

I wonder how easy it is to interface it to an Archimedes 3020? BBC Micro and Amstrad CPC are also potential targets from a 8-bit Brit viewpoint.

I think you're thinking of @croissantking maybe? Or @Hollie. Can't remember who has which.

It was @croissantking , who created a beautiful recapping guide for the QT! I do have one too.. really must recap it soon!

This looks really cool. I don’t have a QuickTake, but want to get one now to try this.
