Atari Portfolio Terminal

Serial Terminal on Atari Portfolio and Atari Card Drive HPC-301

In order to access the Low-Level Test of Philips CD-i players or debug other units with a serial port, you will always need a VT100 compatible terminal. An old laptop with Windows 98 and HyperTerminal works fine, but I was looking for something more portable. The Atari Portfolio with Serial Interface add-on is a good portable choice. Update: …until I found the Psion 5mx Pro.

First of all, we need to transfer the terminal software ACOM to the Portfolio. This is possible via the serial port, but I had to back up some data from the old memory cards too, so I hooked up the Atari Card Drive HPC-301:

The interface card needs an old PC with an ISA slot and DOS. Windows 9x isn’t reliable enough to access the card reader, but the DOS mode works fine. The driver can be found here, and here is some more information. I had less trouble accessing the card reader after loading the driver without parameters, e.g. DEVICE=C:\CD.SYS.

Before starting the terminal software on the Portfolio (command line: ACOM T), it is important to initialize the serial port in the system menu.

This is the Low-Level Test of the Philips CDI660. As you can see, the Portfolio’s screen is limited and doesn’t show the whole menu:

And this is OS-9 saying hi on the DVS VE-200:

  1. I’m searching for a HPC 301 bee card reader pinout or a solution to connect that card reader to a PC, maybe via parallel port, but without using the ISA Card, because unfortunately I doesn’t have such a card, but the reader, memory cards and of cause a Portfolio. I would be happy about any hint or idea. Thanks in advance.

    1. I didn’t experiment with my Portfolio hardware for a while and am not aware if the card reader interface has been documented yet. For data transfer, you could also leave the card in the Portfolio and connect the Parallel Interface to an old PC.
