The DEC Pro 380, including integrated desk unit and color graphics CRT. The CRT can be positioned at any height from 2" to 12" above the desktop by a push of a button. The motorized monitor jack can be installed at either end, or two jacks can be installed. There are two controls embedded in the left side of the desk. The stuff on the desk are a few peripherals and tools lying there, as we had just reassembled the desk and done PM on the LA50 printer, CPU unit, and monitor when our picture-taker showed up.. The system is up and running the menu driven POS operating system, the main menu of which you can see on the CRT. This example is 'loaded', with thickwire ethernet, modem, and expanded memory. The fixed disk is an RD52 and an RX50 dual floppy is present. The unit is in extremely good physical and logical condition with very little wear.
$ SHOW MEM returns: RSX-11M-PLUS 2.1 BL22.(PRO 350) 640K
The DEC Rainbow 100 system includes a monochrome CRT and LA50 printer. A 5 megabyte full-height fixed diak and an RX50 dual FDD provide storage. This unit has expanded memory to 256K and also includes not only the standard CP/M hardware but the optional 8088 allowing it to run DOS as well. This system is running MS-DOS V2.11. It boots DOS or CP/M from the FDD. The HDD is FAT and is accessible by both OS, depending on which you boot. This example sports DBase II, Multiplan, and Wordstar and not a few CP/M programs which we are cautiously investigating as some seem to be disk tools. Although the LOGO badge is shopworn and the unit has obviously processed alot of data, it is is in excellent working order with no errors on the HDD.
The 11/750 is a ruggedized unit preferred by the military. You would not beleive where this thing has been if we could tell you.

This pdp8e needs some repairs to the front panel. We can do it!
Team member bringing in an ASR-33 teletype. "Where do you want it?"
Inside one of the card drawers of a BSL disk memory unit, with a capacity of about 500KBytes on the disk (not shown). An entire rack of these cards, plus power supplies and a large hard disk assembly comprise the entire unit. The unit was not for the purpose of "disk storage", but rather served as a hugely expanded memory array when connected to a pdp8i, which had only 8KBytes of core memory. Yes, this whole rack, full of analog and digital cards, gets you about half a megabyte of random access memory.
The entire BSL rack, and one team member expressing his personal opinion about the technology. Can't blame the gentleman though, as he is spoiled on multiple DEC Alphas, a T1, and other such modern doo-dads.
Two team members conjuring and making incantations to one of the pdp8i's.
Just in case anyone wonders what a typical 'donation' looks like, here is one very generous example, as-given, fresh off a large truck, lined up, and about to be sorted out. There are alot of wonderful books, DECtapes and spare VAX parts in there!
The NCR 399 is a very rare unit indeed. This unit has core memory and booted from cassette tape drives.
This LP26 is an excellent lineprinter!

Another shot of that pdp8i (A big kid with a big toy).
A Sequent 581 machine, with 20 80386 processors, a 9-track, and several Fujitsu Eagle drives. This "low cost supercomputer", or poor man's Cray, ran a unix-like OS called DYNIX and cost only $1,000,000 in 1990.
A Tektronix 4014-1 19" terminal. Quite rare and coveted in any decade.
A DEC TU-80 9-track.
VAX 6510. What a regal machine! 512 megs memory! Not really an antique, but certainly a wonderful classic!
