NORD-10/S serial 619 is a survivor, it's seen some tough times

This is how it looks today.

The power supply was replaced years ago and only parts of the original supply hangs in the wires. The card crates might not have the cards in the right positions or even being complete. I will do some study of other systems that still exist and try to rebuild it into a running state. I will also try to find out more about it's history.

Status

In need of serious repair. Not in a running state.

Configuration

The two card crates are half filled with cards. It has not been documented yet which cards or where they are. It is very possible that cards are in the wrong position.

  • Power supply is just a mess, replaced with a PC power supply.
  • Front panel in good shape.
  • CPU-crate with unknown content.
  • I/O crate with unknown content.

CPU crate

This list reflects the configuration when I got the machine as well as the current one. There might be errors in the original configuration.

There is markings on the backside of the crate that shows what type of card should be in respective slot. This should be checked before trying to power up the CPU.

The CPU crate above and the I/O crate below.
Backside of the CPU crate, colored cables going up is to the front panel, downwards is the I/O bus extension to the lower crate, white is power and the green ones... beats me.

I/O crate

This list reflects the configuration when I got the machine as well as the current one. There might be errors in the original configuration.

It should be checked that there are only I/O cards in this crate. The back plane also needs to be investigated. It consists of two parts but it isn't totally clear where the split is made, probably in a 16+8 block. It also looks like the IRQ chain is jumping over certain positions (yellow wire wrap at the back plane), allowing thicker cards to be installed.

Backside of the I/O crate, colored cables connecting the I/O rack with the surrounding devices and the CPU. The backplane is split in two parts with the bus bridged with white cables in connectors.

Position 25 to 32 is taken up by the NORD-10 HAWK Disk Controller. According to the manual, the disk controller should have a cable connected between position 2 (1022 Bus control) to position 27 (1014 DMA Registers). The connection to the disk is made via three cables attached to position 30-32. [1] A pretty safe guess is that the 1122 Bus control card can be used instead of the 1022. The manual is published March 1976 and the NORD-10/S wasn't really on the market yet.

History

  • Original owner not known.
  • Part of the computer park of the FUN (Forskarföreningen Umeå Naturvetare) society around 1985-1995.
  • Previous owner tried to get it running by replacing the power supply 10-15 years ago. It never started.
  • It's been in my care since around 2003 when the previous owner put it in my workshop and tried to get it running. It's been with me through two moves since then. Last move was in 2017 and hopefully it was the last one in a long time.

Future plans

  • To begin with just check if the system is complete enough to get into a running state. The old power supply is obviously beyond repair, but a modern PC power supply should be able to power the system.
  • Test if it will do anything close to running and why not.

Extras

There are some documentation that I haven't received yet.

Location

The system is in the care of Göran Axelsson and is located in a storage close to Umeå, Sweden.
