Exomizer is a program that compresses files in a way that tries to be as efficient as possible but still allows them to be decompressed in environments where CPU speed and RAM are limited. For some popular 8-bit computers using 6502 compatible CPUs it can also generate executable files that decompress themselves in memory when run.

• 2011-08-19: Exomizer v2.0.2 released

Changes since the 2.0.1 release:

• Added 6809-decruncher contributed by Edouard Forler.
• Fix language errors in the documentation. Thanks to Csabo/LOD.
• Remove bogus printout about the default decrunch effect when using a custom decrunch effect. Bug reported by Csabo/LOD.
• Fix bug that prevented the correct error message from showing when trying to combine a basic start and a non rom config for the sfx command. Bug reported by iAN CooG.

A complete changelog is included in the zip file.

VirtualC64 emulates a Commodore 64 personal computer on your Intel Macintosh OSx > 10.6.

I wrote the software with two major goals in mind. First, I wanted to create an emulator that can be used as a demonstrator program in a first year or second year course on computer engineering.

To achieve this goal, I have integrated various debugging capabilities that let you peek inside the CPU, RAM, ROM, or one of the custom chips. Second, I tried to make the emulator as user friendly as it can get.

In short: VirtualC64 tries to combine the ongoing fascination of the ancient Commodore computers with the great user experience of today’s Macs.

Bug fixes and enhancements:

• Fixed another bug that caused the emulator to crash on some lion machines.

Kick Assembler is the combination of an assembler for doing 6510 machine code and a high level script language.

Kick Assembler comes with an exe file so you don’t need to install java. The jar file is still distributed – we will keep supporting all java compatible platforms (Linux/Osx).

8/8-2011 : New beta release (v3.19) – The LCP Release:

• You can now use the questionmark if notation in expressions. Eg. .var x = a
• Added a fillbyte option that sets the byte used to fill the space between memoryblocks in the prg file. Usefull for writing a eprom or flash (I’m told, hope you can use it Alex :-)
• You can now cast values to a numbers or strings by using the .number() or .string() function. Eg x= 1234.string().charAt(2) – sets x to 3
• Chars now have the same functions as numbers (+,-,*,,
• Made a quick reformatting of the manual since my new version of word had thrashed the layout.

C64 Studio is a .NET based IDE written by Georg Rottensteiner. This app supports project based C64 assembly.

The internal assembler is using the ACME syntax. In connection with Vice the IDE allows you to debug through your code and watch variables/memory locations, registers and memory.

Any other emulator can be set up as well if it’s startable via runtime arguments. C64 Studio allows you to compile to raw binary, .prg, .t64 or cartridge format (.bin and .crt for 8k and 16k). Additionally to this C64 Studio comes with a charset and sprite editor.

Version history:

16.08.2011 – 1.6:

• Fixed parse bug, things like LDA #’H’ can now be parsed.
• Complete rewrote GDI handling for sprite and charset editor (no more resource leaks)
• Added Pre/Custom/Post Build events per configuration (useful for exomizing)
• Fixed some crash bugs.

Digital Audio Concepts has released a new version of the program Stereo Sid-Player originally written by Mark A. Dickenson.

The latest version released by Mark was the v10.3.

Changes since v10.3:

• Added second-SID addressing for $D100-$D3E0, $D500-$D7E0, and $DE00-$DFE0 ranges.  The second SID can be placed at any $20 byte increment within these areas.
• Fixed the hard-coded device 8 for the config file loader/saver – now the program expect to find/put this file on whatever device you booted from.
• Fixed the hard-coded device 8 default for the music loader – now the program will load music from whatever device you booted from when no config file is found, unless you change it and save a new config file.
• Deprecated one byte and added two new bytes to the config file, to handle the new method of storing the second-SID address (now uses program’s internal indexes instead of a page number, so it can be looked up easily on load).
• Renamed config file to avoid confusion with the old version.
• Disabled the intro tune (it broke during the update – will fix later).

petSD is the name of the new AVR-based hardware. It’s a modern mass storage solution for Commodore PET/CBM computers with IEEE 488bus using SD cards as floppy or hard disc replacement.

If you know the SD2IEC or µIEC: the petSD is just the same but for the older parallel IEEE 488 bus instead of the newer serial IEC bus.

Site update:

Nils Eilers has made a new layout with some bugs fixed and has ordered a first batch of PCBs.

from OldComputers:

The Atari 520ST was introduced at the Winter CES in January of 1985, 6 months before the Commodore Amiga. Atari did take some shortcuts, though, as the Operating System did not yet exist in ROM, and had to be loaded from floppy-disk when powered on (but then again, so did the Amiga). The 520ST also had no internal floppy drive, but later versions included it.

Bundled with an external 360K single sided 3.5 inch floppy drive, mouse and monochrome monitor, it costs $799. Both Amiga and 520ST are based on the Motorola 68000 CPU, which has a 16-bit external bus, and 32-bit internal, thus the 520′ST’ means ‘sixteen / thirty two’. The Operating System is ‘TOS’, or ‘Tramiel Operating System’.

The 520ST (and Amiga) have a graphical operating system, or GUI, similar to the Apple Macintosh, which was released one year earlier. The 520ST utilized Digital Research’s GEM GUI, although it is not nearly as nice as the Macintosh or Amiga.

One thing that IS very nice is the built-in VT52 emulation. The 520ST can act as a dumb terminal, communicating through its serial port to another system. There was a huge rivalry between Amiga and Atari users, each positive that their computer system was superior, or at least hoping it was.

In addition to the 520ST, Atari release the 1040ST, with built-in floppy drive, and 1Meg of RAM (the 520ST has 512K). Four years later in 1989, the portable ST computer appeared, the Stacy.
