Yesterday I picked up the PDP11/04 that Jay mentioned a few days ago.
Less than 15 miles from home !
The machine spend its early days as a processor in chemical analysis apparatus, and was subsequently bought by the employee using it.
Before he could make use of it better, more powerful, easier to use machines came along and the -11 spend the next 30 years in a garage.
The -04 is an entry level machine, and the cards inside match this :
M7263 KD11 CPU
2 x M7264 16K DRAM cards
M7856 DL11 SLU/RTC
M7846 RX01 controller
2 x M7814 DZ11-F
and of course the M9301, M9302 and M9202.
Alas it has just the simple 2-switch frontpanel.
The machine also had the battery backup option, and the lead/acid batteries will celebrate their 40th birthday next year !
Better not try to charge them....
Overall the machine is in very good condition, both CPU and RX01, and it is packed in a very nice half-height rack with the red PDP11 bezel at the top.
Pictures next week when the machine is cleaned and reassembled, restoration is to start next winter, after a house move which will nearly double working area for the hobby.
Many thanks to Roland for preserving the machine, and to Jay for acting as an interface !
