Following my mishap with the IWM chip in my trusty IIc, I sourced another one to have a backup before attempting a repair. Now cleaning it up! It's in very good state both externally and internally. It's an A2S4100 with ALPS keyboard!

I updated my #vccc2025 entry so that the binary is the bootsector, no need for ProDOS. This loads much faster ! (And also provides you reader a spoiler, you can now guess that my code is less than 512 bytes - which is a very low bar, given that the pattern to […]

I broke my Apple IIc with a "quick test just to check something". I don't know what I did wrong but probably a short or static.
Now my IWM chip thinks WRPROT is always low, which makes for a fully write-protected Apple IIc, both internal and […]

J'ai découvert hier qu'il y a une asso de commerçants dans le quartier pas loin de chez moi, et donc sachez que cette asso des commerçants des avenues de l'URSS et Crampel s'appelle le Comité des Commerçants et Commerces de Proximité, c'est à dire CCCP 😅

Two other pictures from yesterday's Insert Coin 3 retrogaming event. In these pictures it's easy to guess who just scored a point against their opponent!

Then I proceeded to do the same on W2, and... immediately ripped off the chip-side pad and broke the trace 😭
After pondering my options, I decided to drill a little hole at the place where the pad was, after verifying I would drill into another trace on the other […]

But I want to make it easily reversible, so I planned on soldering jumpers on the pads. I cut open W1 and soldered a jumper. Neat, working.

Apparemment dimanche 16 novembre je vais aller à l' Insert Coin 3, un petit évènement #retrogaming, à Canals (82), et je vais y amener mon Apple IIc, Glider et Shufflepuck! Ça devrait être sympa !

- handle mouse detection
- handle VBL
- play sound

The left is the image data. The grey band is left alone by the JPEG decoder, but used by the final scaler afterwards (which uses 256x16 bytes), so has to be left alone.
The red band contains data tables, which by chance were exactly the 64 bytes left at each end […]

The original Quicktake 200 images are 640x480 JPEGs, as seen in the first picture of this post.
My decoder first scales it down to 320x240 and drops color (second picture).
The final picture size is 256x192 (nearest neighbor), which is the one that then gets […]

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 !
https://www.colino.net/wordpress/en/quicktake-for-apple-ii/
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!

Well well it seems I still had two ideas for these 87040 divisions. The function even disappeared from the top 30.
As every final pixel value is computed using a division with a divisor that is identical for four rows at a time, a second, dynamic division lookup […]
