This is another Z80 luggable machine from the 1980's. Its less powerful but essentially similar sibling is the more common Kontron PSI80. Both machines are expandable through ECB cards, the PSI98 has six slots.

The basic characteristics are a Z80 CPU at 4 or 6 MHz, 256K RAM on board in four 64K banks, 4 or 8K PROM, Memory manager for 16MB, Z80 DMA, 64Kx10 Video refresh memory, 2 CTCs (8 counter/timer channels), 16bit PIO, 2 serial channels via SIO, parallel keyboard, RTC, SASI connector (expects an MFM harddisk connected via an Adaptec ACB-4000 SASI=>MFM board), MC6845 video chip, character generator for 256 or 512 characters, alphanumeric and 512x256 pixel graphical display.

Here are the links for photos, manuals, ROMs and disk images, I've uploaded them to the FTP as well.

The machine consists of three boards:

My machine must have been used in some kind of process control setting - it contains some extra ECB cards:

Two memory cards

One I/O card

One card with lots of relays

The disk images and manuals in the archive come from this site

http://oldcomputers.dyndns.org/public/pub/rechner/kontron/images/index.html

My machines boots KOS and a disk made from the CP/M image, although it's clearly marked for the PSI80 - according to the documentation however, the PSI80 doesn't have the right disk drives for that endeavour.

The disk format is a somewhat strange 5,25" DS DD 77 tracks, 16 sectors per track, 256 bytes per sector.

The machine has a SASI interface, but connecting an old SCSI-1 disk didn't work out of the box. The utilities are expecting an MFM harddisk connected via an Adaptec ACB-4000 SASI=>MFM board.

Ok, implemented an initial version of the memory and gfx system, this gives us:

At this point it tries to boot from floppy (not hooked up yet).

Do you have any idea what the CPU in the keyboard is?

Looking good! That's just the message you get on the real thing:

The keyboard MCU is an 8031

Seriously, I'd love to know the function of it. That DIN key is intriguing, too.
