I will have to check (and my 4070s)

The Facit 4070 might have been (the first version of the logic board
used DTL I seem to recall) but the N4000 is much later. There's a 6809
microprocessor and a 68701 microcontroller in there.

On the page about the Facit N 4070, (the page is really about the BESK)
is a link to a early computer generated film: 
https://youtu.be/XhNT501DsJI

Using the BESK, the road designers of the motorway between Stockholm
and Nacka was able to simulate driving on the road.

When was your punch made in Åtvidaberg ?

According to Tekniska museet (museum of technology) Stockholm, they
were made between 1968 to 1999.

About 145000 done in total.

Would love to see it, I have such a machine in the queue for restoration.

I would love to see copies of anything you've done Tony. I was unaware you were 
doing this, I am fairly certain I have full docs including service manual on 
the n4000.

tape punch/reader unit. The one that looks like a Facit 4070 with a
tape reader on the front (in fact the punch mechanism is much the same
as that in the 4070).

I have reverse-engineered mine and traced out the schematics. Of
course it's one of my hand-drawn ones but I think it's mostly legible.
If anyone wants it I am happy to send out a copy (but as ever I'd
rather send it out once and have somebody else pass it on)
