You think this looks like the bastard child of a Siemens machine, the ITT3030 and the NCC1701? HELL, you're right ... and it's hell of Linotype-Hell fame.
They took the TA P2U as a basis for their typesetting system, put it in a late 70s fugly plastic case, combined it with a stock keyboard from their mother company and mixed and matched with other components from the SKS grab bag. The disk drives look familiar, as does the CPU card, although the christmas sticker is a nice touch
Lots of extra keys on the keyboard which is appropriate for a typesetting machine. The keyboards uses a different connection than the P2 series, it needs is read via the INT7.5
helwie44 was with the Hell company, and he's sent me his files which I've put on the FTP but can also be found here.
What really sets the DS2069 apart from the Alphatronic line is that it's missing a character generator. The usual Video RAM is stacked four banks deep, and the machine initially comes blank, you have to blindly type in "B" to boot and then load a character set using the "LF" command. The blank lines are a feature, the characters are 16x16 pixels.
This mechanism allows to use four character sets concurrently.
The archive contains the MOS and keyboard proms and some disks as well as the photos of the cards and lots of documentation.
