Commodore Free Magazine, Issue 95 - Part 4

, is going to ported to MiST
FPGA (unofficial news)

The website says

A cycle exact FPGA core for the MOS 7360/8360 TED chip written in verilog.

The final goal is to have an fpga core that could be used as a drop in
replacement for the MOS 8360 chip which is the heart of the Commodore 264
series 8 bit computers, namely the Commodore 16, Commodore Plus 4 and
Commodore 116.  This core can be the basis of a complete C16 or Plus 4 SoC
implementation

More news from Chris Syntichakis

Hi commodorefree

core only can load/run .PRG files, no support for D64/tape images

The dev site says:

FPGATED is a cycle exact FPGA core for the MOS 7360/8360 TED chip written
in verilog language.  MOS 7360/8360 is complex chip providing graphic,
sound, bus and memory control for the Commodore 264 series 8 bit computers,
namely the Commodore Plus4, Commodore 16 and Commodore 116.

From: Christian Krenner
To: Commodore Free

Hi Nigel,

just a quick update.  You can see the latest reincarnation of Space Chase
here (played on a real CBM II machine):  youtu.be/Ixvac1yw_5M

There are only a few bugs left, I am still planning to release 1.0 in a few
weeks.

Regards
Christian

         AISS 4.21 AVAILABLE
*************************************

The Amiga Image Storage System (AISS) offers a photo-illustrative icon
style for toolbar images - it approaches the realism of photography but
uses the features of illustrations to convey a lot of information in a
small image.  AISS is an environment to store, access and maintain this
toolbar images.  For more information about AISS please have a look at the
documentation.

The new release features more than 8,700 images in the AmigaOS 4 icon
design and for compatibility reasons all pictures and animations of the
previous releases.

         COMMODORE SID CHIP
*************************************

Although the SID chip itself doesn't need any sort of introduction, I will
do one anyway for the purpose of educating the people who don't know.

SID is an acronym for Sound Interface Device.  The chip was Developed by
Bob Yannes, who worked for MOS Technology.  He wanted to create a real
subtractive synthesis chip, so it would stand out from the usual music
chips of the time.  The chip is a combination of both analogue and digital
circuitry, because of this, many people say the sound is impossible to
emulate with 100% accuracy The first Commodore 64 or breadbin uses the 6581
chip while The Commodore 64 mark II and Commodore 128 use the newer 8580
chip.

SID AT A GLANCE

* 3 voices,
* 4 waveforms (sawtooth, triangle, rectangle pulse width modulation, (white)
  noise
* 3 amplitude modulator,
* 3 envelope generators
* Synchronization of the oscillators
* Ring modulation
* Programmable filters (low pass, bandpass, high pass)
* Master volume control
* 2 A/D-converter (8 bit, low frequency, used for reading paddle input)
* Random generator
* Audio input

There are a number of differences between the two versions one being the
filters, many SID musicians prefer the errors in the original 6581 chip,
Yannes worked and corrected many of these for the newer 8580 chip.  Speech
sounds better on the first chip, while the second sounds muffled in
comparison.

EMULATIONS

Unfortunately for the SID chip, many of these devices produced between 1982
and 1993 reach the end of their life span.  It is getting harder to get a
replacement parts, although some seemed to find their way onto ebay they
were thought to be rejected by Commodore and someone returned them to the
market, with faulty filters and even sound chalnnels.  Thus, it was deemed
that we need a proper substitute.  And as the website says this is what the
FPGASID project is all about!

The project was started to overcome not only the shortage of replacement
chips, but try to produce a more stable substitute, and in the emulation
this is said to reach close to 100% emulation, or as the site states " it
aims for a better SID than any SID has ever been before..."

THE MISSION

* Create a pin compatible drop-in replacement for the MOS6581 device
  as well as for its successor, the MOS8580.

THE TARGETS

* To-the-cycle exact reproduction of all digital parts including sound
  and envelope generation and paddle readouts.

* Exact modeling of the analog parts leading to a result that is almost
  indistinguishable from the original.

* Making it configurable to easily switch between various SID variants

* Adding extra features like wavetables, stereo sound, more
  voices, etc., while keeping full compatibility.

THE MEANS

* Use of FPGA technology. It is more suitable than software related
  emulation.
