Rhotron
Niemieckia firma RHOTHRON specjalizujaca sie informatyką HiTech dla wielkich firm używających komputerów falcon. Samochody MERCEDES, OPEL i produkty firmy SIEMENS były opracowywane na komputerach Falcon. Dlaczego akurat Falcon? Dzieki DSP 56001 umożliwiającym mieszanie źródeł analogowych i numerycznych.
Wykonane projekty:
- automatyczny/kontroler czyli Falcon 030 z 11 toma szynami VME nazwany RHO-PROCESS
- Le RHO-TRANSIENT PLUS czujnik frekwencji
- RHO-DATENLOGGER II, czujnik numeryczny używający DSP
FX-1/Sparrow
W roku 1991 Atari postanowiło zastąpić stare ST/E nową maszyną.
They realized then the "Sparrow Card", which was a development card plugged into the 68000 slot of an Atari 1040 STe.
The "Sparrow Card" had one of the main feature of the future FX-1 / Falcon 030 computers : it was a dual CPU board. It used a Motorola MC68030 and a Motorola DSP 56K.
The "Sparrow Card" used a 16 MHz 68030, a 16 MHz 68882 (arithmetic coprocessor) and a 32 MHz DSP 56K with 24 KB of static RAM.
Later, when Atari made the first fully functionnal computer from this prototype board, they planned to name it "FX-1", they eventually name it "Falcon".
The Atari FX-1, or "Sparrow", is also a prototype machine. Actually, it is almost a Falcon030. It has all its features except its true color mode (not fully implemented in the FX-1) and the PCM sound channels (12 bit instead of 16 in the Falcon).
These computers used the Atari Mega STe TOS (2.06) slightly modified to cope with the new graphic modes. This TOS version had the number 2.07 and was replaced in the last Sparrow models with the TOS 4.0 (The Falcon used TOS 4.01 in the earlier models, then the 4.04 and finally the 4.92 (never released)).
Atari produced less than 100 of these machines. They were built with sample spare parts and were used by developpers to write software for the future Atari Falcon.
Curl Vendel says : Originally, the Sparrow/FX-1 had a better graphics processor, but it was incompatible with most software. A newer processor was built that was more compatible (yet slightly crippled) with ST/e software.
Anfang 1992 wurde der Prototyp des Atari Falcon einigen Entwicklern präsentiert. Etwa 150 Vorserienmodelle wurden dann Mitte des selben Jahres an europäische Entwickler ausgeliefert. Einige dieser Rechner trugen das Label FX-1 wärend auf anderen der Name Sparrow prangte. Der Festplattentreiber des Prototyps meldete sich beim Booten mit "Sparrow" und benutzte den Blitterchip für den Datentransfer zur IDE Festplatte. Auf dem Board wurde ein TOS 4.00 in 2 Megabit großen DIL Eproms als Betriebssystem eingesetzt. In einer frühen Entwicklungsstufe war es sogar ein TOS 2.07, welches die VDI Routinen für die Bildschirmausgabe von Platte nachlud.

Karty graficzne
Die "Crazy Dots 2" Grafikkarte der Firma TKR für die Rechner der Mega ST-, Mega STE- und TT 030 - Serie ermöglichte eine Bildauflösung bis zu 1280 x 800 Pixel in 256 Farben und bis zu 1664 x 1200 Pixel in 16 Farben aus einer Farbpalette von 16,7 Millionen Farben. Zusätzlich gab es noch ein 32K-Erweiterungsmodul, mit dem 32.768 Farben gleichzeitig auf dem Bildschirm angezeigt werden konnten. Als Grafikchip kam ein TSENG ET4000 auf der Grafikkarte zum Einsatz. Mit Hilfe eines komfortabler Videomode-Generator war es möglich, beliebige, auch virtuelle Auflösungen zu erstellen. Oben im Bild sieht man die Mega STE bzw. TT Version (VME Slot) der Grafikkarte. Außerdem NVDI ET4000, welches alternativ als Grafikkartentreiber und GDOS Ersatz verwendet werden konnte. Die Crazy Dots Grafikkarte kostete Anfang 1992 etwa 998,- DM. Die Version mit 32K-Erweiterungsmodul wurde für etwa 1198,- DM vertrieben.

can I enjoy enhanced graphics on my ST?
For stock STs, JRI makes a chip which allows a 4096 color palette. There is also a public domain enhancement that allows 32768 colors on older STs. This can be found as 32kcolor.lzh on some archives.
There are a number of graphics boards on the market. Here is a first pass at listing some of them. The information is based on postings by Ben Gilbert and Jari Lehto.
C32 board by Matrix Datensystem (Germany)
* 800x608, 256 colors
* all ST/TT models
* 256k, 512k and 1meg versions
C75Z board by Matrix Datensystem (Germany)

* Mega ST or STe, TT VME Buss
(Matrix GmbH has over 15, maybe over 20 with all versions, different graphics boards available, from hobbyist to professional, from CAD to GenLock and digitizing.)
ISAC board by Dover Research Company (U.S.)
