A nice trip from Frankfurt (Germany) to Luzerne (Switzerland) to pick up an RK07, a Dec Writer IV and a huge amount of Unibus Cards.







I have bought all via ricardo.ch but missed a PDP11/24 with many devices placed in two H960 Racks for !!20.- CHF!!, which was sold from this seller some weeks before. 🙁

But, …

A complete RK611 Backplane and Controller was included, also a near complete 11/70 Board-Set.

Initially it was planned to sleep in a small hotel in the near of Lucerne but one day before they cancelled the booking and told us that they have no room for travellers with a so big dog.

As we have not found any other hotel, we have decided to order some camping equipment and enjoy the nature. Thanks Amazon Prime, as the order and delivery was near in-time.

Here we are! It is a small private ground where you can stay, > after you have paid some bucks. 😉
