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.

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 a bug that caused the emulator to crash on startup on some machines.
• VirtualC64 supports OS X Lion.
• Preference panels are now tight to their individual virtual machines.
• CIA debug panel has been redesigned.
• Deprecated CoreAudio API calls have been removed.
• Fixed a bug in the BCD to binary conversion routine.
• Fixed a bug that caused the TOD to wake up too early after reading the tenth of a second register.
• Thumbnail images are now rendered properly when switching from PAL to NTSC and vice versa (issue #107)
• Fixed a bug that caused keyboard events to be rejected when the main window got focus (issue #110)
• Fixed a bug that caused a discolored line to appear at the right border of the screen texture.
• Yet another startup animation.

from Wikipedia:

The KC 85 (‘KC’ meaning “Kleincomputer”, or “small computer”) were models of microcomputers built in East Germany, first in 1984 by Robotron (the KC 85/1) and later by VEB Mikroelektronik “Wilhelm Pieck” Mühlhausen (KC 85/2, KC 85/3 and KC 85/4).

Due to huge demand by industrial, educational as well as military institutions, KC 85 systems were virtually unavailable for sale to smaller customers. They were based on the U880 CPU (an East German clone of the Z80), with clock speeds of 1.75 and 2 MHz.

There were two main lines in the KC 85 series, the KC 85/2 (project name HC 900) to /4 and the KC 85/1 (project name Z 9001) by Robotron, which was a different system (only the CPU and the name were the same, but later the format of saving the programs on tape cassettes and the BASIC were also made compatible). In 1989, VEB Mikroelektronik Mühlhausen came up with the KC compact, but due to the GDR collapse very few units got actually produced and sold and — being a CPC clone — it was a KC in name only; thus it is usually not counted among the KC family.

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.
