Friendlyarm Nanopi Neo2 Starter system.

This is a nice enclosed metal case quad core Allwinner H5 processor.

This is a photo of the unit in visible light, then photos of the unit from various angles in IR with a Flir Pro camera.

This seems to be a 16 bit Basic Four processor set. It's in unusable condition (most likely), and hopefully will yield up the firmware at least.

The possibility it being a 16 bit superset of the 1600 is due to it having 4 74181 ALU chips. It was designed just shy of the advent of the 2901, which I believe was the next step in the Basic Four / MAI designs of CPUs.

There are 4 total boards in the scrap set, one with the firmware (Intel mask roms), the board with the 74181's (probably the Data board) one with a lot of logic, and a final one with two large connectors out the back (maybe a path to control panel)?

Will have to see if anyone has more Basic Four information.

DPS 8 system test attachment. Possibly Multics

This was found in a gold scrap listing, and sadly isn't much more useful than that. However it does have references in the DPS8 manual.

Also on Archive.org with OCR. I didn't find an OCR'd version on bitsavers.

Data General Eclipse front panel

This is a nice buy off of Ebay. It happens to use the same plastic casting as the Nova 3 front panel bezel (of which there are three in stock).

It didn't say which model, but I'm suspecting S-120 or such unless corrected.

Also the seller nicely left the key with it, or didn't notice it, so there is a genuine (I'm guessing) DG key. I had just gotten a replacement Ace for the Nova 1200s, so now have keys for all of the ones with key on / off.
