Looking for Manuals and Software for ESVD + PSM7 EMC Setup

[Astralix]

Hi!

Im currently collecting information for my ESVD + PSM EMV project. While I do have all needed manuals for the ESVD and, besides the batteries, the unit I have still performs fine, I miss a lot of stuff for connecting the PSM7.
The PSM7 is an 486 based industrial control PC also made by R&S. It features things like LCD monitor, menu keys under the monitor, additional optional numeric keyboard and 2-line LCD on the front and other stuff.

But it starts with the PSM7 failing to boot as soon as I add any additional ISA card. Also I managed to get original R&S IEEE488 cards and the HDD still running with the former IEEE, AH1542 and Ethernet adapter settings clearly readable in CONFIG.SYS and AUTOEXEC.BAT, the BIOS will not even get to init the VGA card as soon as I add a single additional card. I changed all caps on the bus board, used a different PSU and already changed all bus drivers on the original 486 PC ISA Card. No success.

Unfortunately, there is a lot of stuff going on on the bus board. Besides the 10 ISA Slots there is some MCS51 based stuff that may be for system management and TTL / Analog I/O. There are TWO Super-IO Chips featuring support for 4 HDD, 4 Floppy, 4 COM ports and 2 parallel ports. And then there are two large CPLDs of unknown reason, CF card reader and whats not on the Bus board.

While I have all documentation for the PSA series I cannot find a single doc for the PSM series. Also I was told that there are copies of the old DOS and may be early Windows Software out there, but I cannot find any.

And to round things up, I wonder if someone could hand me a copy of the ES-K1 disks what will combine the PSM7 with the ESVD to a good old EMC measurement setup. Just for fun and to show off to the kids to have them pressing buttons and learn something.
Still, I need to find out, why the unit stops working as soon as any kind of additional ISA card is plugged in.

Thanks in advance!
