As promised, some more pictures.
First, the disassembly of the main unit. Inside, dust and even more dust.
Giant power supply, and a very tiny main board, compared to it.
Power supply opened for cleaning and inspection - what a beauty!
Ports, as seen from the outside:
Connecting all hardware together - despite all connectors being different sizes, there are clear markings both on the machine and the connector itself, with numbers, which connector goes to which port. Nice!
Finally, the test run - all the way to *11* - which means system is waiting for a bootable floppy, which I do not have. The disk drive is spinning, but making squeaking noises - might need cleaning and lubrication, if possible. This will be the next task, to open the giant and extremely heavy floppy drive.
The keyboard - it is an early version of IBM model F, with lots of dust, dirt, broken fingernails and all things you can imagine could fall into it. Time for a cleaning!
Now comes the first issue - keyboard cable looks to be damaged. In fact, the damage to the cable seems to be a strange one, the wires look cut rather than broken. Did someone manage to replace original beamspring keyboard with this one in a brutal way? Any ideas?
Now, the keyboard with top cover removed. One wire has been disconnected, the question is - should it go to upper two pins or lower two pins - there is no where else I can connect it to.
The other side of the keyboard - all metal, in fact, the keyboard is an extremely heavy one, compared to the ones we use today, but feels extremely solid as well.
No other tests can be performed before I get a bootable 8 inch floppy for this computer. The keyboard issue makes me worried, however, given the fact that system diagnostics does not show anything unusual, it might as well be working. (I get three error codes when starting the Displaywriter with the keyboard disconnected).
