Datanetics Apple Keyboard Fix Datanetics Apple Keyboard Fix

Datanetics Apple Keyboard Fix.

After a few cold solder joints redone the keyboard works almost perfectly.

Todo:

  • The “V” key is totally dead.
  • The keys are a bit tired, don’t return always in the original position.

Overall is fine.

Datanetics Apple Keyboard *update*

I found a temporary solution for the tired keys they don’t return always in the original position. I have put a small spring (see the picture). Now the keys works correctly.

About the “V” key completely dead, i have desoldered it and i have tried to spray a air into the slots without having any results, so i have tried a extreme thing, i have used the key switch like a whistle. ;-D I have blown inside several times, the result is the key switch now are working again. I have made the same thing for the “right arrow”.

My advice is always to replace all capacitors although at first view does not seem exhausted with acid leakage.

durexForth v1.3 (Forth language for Commodore 64)

April 17th, 2014 No comments

Forth, the Language.

Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.

It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

HermIRES v1.29 C64 hires-bitmap editor

March 18th, 2014 No comments

HermIRES it’s a cross-platform hires bitmap (Art Studio 1 format) editor for the Commodore 64.

The format has some restrictions, here are the rules:

  • The maximal resolution of the picture is 320×200
  • Only 16 fix C64 colours can be used (no gradient either)
  • In a 8×8 pixel-block only 2 colours can used to be displayable by C64 (this is detected in HermIRES, but .hbm files can be saved with clashes too.)
  • On a real C64 the PAL will blur the screen-content a bit, should check on CRT, or at least VICE emulator’s CRT simulation.

Changelog:

  • AFLI caption can be fully disabled (AFLIexe-patch included along with bin2array.exe)
