Datum MDP/1-MPU

Front panel for Datum mini computer.  Seems to have been microprogrammed, judging by the front panel display / switch to examine or display control store.

16 bits, has a switch for selecting display or examine of 4 registers.

Also, nicely, it has hexadecimal display with the switches grouped by 4 bits.

Flowers

There are bushes that are pretty much useless green blobs all year, but which now have nice blooms on them

Boeing B-52G Load Adjuster

I bought a load adjuster "case" today, which happened to have a B-52G Adjuster in it.  It was not listed by the aircraft type, but by the case part number. 

It is so new it still has a "leather" smell, and the slide rule is perfect.

Manuals which came with two Data General Nova 4 systems.  Drawings will require a B size scanner.

A604F Flip Chip Module DEC 2 Bit D-A Converter

The A604 revision F is a 2 bit D-A converter

Difference from Revision E on Vince Slyngstad's site is a date of 2/68, and a bit of trace going off the edge of the board from what is probably one of the grounds.

Will verify the components and etch and update.
