Developer: PIOS
Announcement: 1997
During the dark days of 1996 the Amiga sunk to an all-time low. Escom had entered liquidation, cancelling any development plans that were underway. To keep the Amiga spirit alive, a new company was created by the former employees of Amiga Technologies. Under the name, PIOS systems and led by Dave Haynie, one of the Amigas engineers during the Commodore era, they set about creating an Amiga style computer using the latest hardware. Rather than making the mistake of completely redesigning the entire system from the ground up, they combined some of the movers in the hardware and software industry to create a powerful machine with a great deal of software support.
The TransAM was the Amiga-oriented version of the PIOS One (unlike the Maxxtrem and Keenya that were aimed at the Mac market). Its name reflected the machines ideology, it was a TRANSitional Amiga system that would move the Amiga market onto the PowerPC without the baggage of legacy hardware.
The company released an initial specification list during 1997, but this was replaced by an updated version in February 1998.
Early PIOS One Specification List
Soon after the PIOS One's announcement, PIOS provided a brief description of the system hardware.

TransAM-200
Several news articles indicated that PIOS would also release a 200MHz model. This would be shipped with:
CPU 603p 200 MHz
RAM 16 MB
Graphics PCI 2 Mb SVGA card
L2 Cache 512 KB
Drives EIDE Harddisk, 2.5 GB
12x ATAPI CD-ROM
HD floppy disk
Software pOS
BeOS
Linux
MetroWerks Codewarrior Lite for BeOS
An Office software package
Expected price £978
Hardware
The hardware schematics and feature list were in a constant state of flux. The final feature list, dated February 1998, provides a detailed diagram and additional information on the board:
PIOS One System

Hardware Hardware Notes
CPU PowerPC 603 & 604
G3 & G4 expected to be used at a later date
Support for mult-processing using compatible operating systems.
This would allow the use of two older processors for maximum efficiency.
Flash ROM Up to 1MB of flash ROM
RAM 168-pin unbuffered 64-bit DIMM modules
Sound Aureal AU8820 on the PCI Bus The AU8820 offers multichannel music synthesis based on samples stored in main memory, MIDI, game port, and
digital I/O expansion.
The Aureal chip is an audio processor, which generates sounds using an industry-standard AC97 CODEC.
Interfaces 5 PCI (two 64-bit slots, three 32-bit)
Two ISA slots (absent in Maxxtrem system)
Two port USB
EIDE/ATA-2 controller
SCSI-2
SCC Interface (two ports)
ADB Interface
Digital Audio I/O port (DAI/O)
'Macintosh-compatible' RS-422 Serial
Standard RS-422 The Hydra chip, designed by Apple for the PowerPC Platform, adds support for SCSI-2 host adaptor integration, as well as CHRP compatibility and additional serial interfaces.
The Macintosh-compatible serial connector, based on the RS-422 standard, is a 9-pin mini-DIN socket.
The faster RS-422 ports can be used for some kinds of printers, multichannel MIDI devices, modems, and
cheap networking.
Each of the serial ports has individual read and write DMA channels, to offload the CPU and avoid any latency problems.
Keyboard interface PS/2, USB, or ADB keyboards
Operating System
Rather than creating their own operating system as Phase 5 had promised with the A\Box, PIOS decided to link into the momentum of alternative operating systems that were available at the time (BeOS, MacOS, and Linux). The desire to build upon the remains of the Amiga market was quite strong, given the companies Amiga background, resulting in discussions with Viscorp to create an AmigaOS PPC. However, the delay in Escom's liquidation resulted in the cancellation of this idea and the adoption of pOS.
TransAM 2001
Since the specifications for the TransAM were released during 1996 the computer marketplace has changed quite considerably. However, the PIOS One design was bought back into the limelight in April 2001 for a final time. At this point in time it was used as an example of Amiga Inc's current plans for AmigaOS 4 and the AmigaOne. Amiga sought to educate Amiga users on the alternative solutions that they can provide and demonstrate the requirements for a contemporary platform. The TransAM could be considered to be the spiritual ancestor of the AmigaOne.
