These boards were obtained from a warehouse clearance along with a DG MV/2000 and other Data General hardware. These boards appear to have been stored as spares. According to documentation obtained with the boards, the company used a Nova 2 and Nova 3 before the MV/2000.
This particular board is labeled "MK8018". This board was made by Mostek as a compatible part for Data General and other minicomputers. Here is some information on the board from an old edition of Computerworld: "Th...ink of the added confidence that on-board ECC and diagnostics can give you. For NOVA 4/X & 4/S minicomputers, our fully compatible MK8018 memory system features an on-board single-bit error correction option complemented by an 8 LED error log display. With it, you can troubleshoot to the individual RAM level. Using industry-standard Mostek dynamic RAMs, memory configurations for the MK8018 range from 32K x 16/21 up to 128K x 16/21."
The boards measure about 15" x 15". There is no sign of cracking, rust, or knocked-off components. There is a small amount of coppery corrosion on the gold of the card edge, but it is not deep. The boards come with the plastic "spacer" cards that go between the cards when installed, as well as the small metal handles for installation and removal.
I am open to performing tests at your instruction (I have equipment), taking additional photos, or anything else that can help you determine if these are the boards you need for your Data General Nova restoration.

Legal Disclaimers: Vintage and legacy computer hardware is intended for purchase and use by qualified users and hobbyists who are aware of the inherent risks of the hobby. Most vintage hardware is past its designed lifespan and therefore may have leaking capacitors, rotten electrical insulation, failing plasticizers, breached CRTs, high-voltage shorts, and other potentially life-threatening hazards. Additionally, some hardware for sale is UL listed (or similar test agency) as commercial or industrial classed, and therefore is not intended for operation in a residential area. Some devices will require freight shipping. Always inspect internal cables and capacitors before turning a device on, including a tested device that has been recently shipped. Always plug vintage hardware devices into a quality surge protector or if using a three-phase system, use one with appropriate line filtering. Hard drives will be shipped separately for large servers. We will require insured shipment of any device with a CRT due to their extreme sensitivity to rough handling. Disk drives and other magnetic media will also have increased shipping costs since they will need to be marked as sensitive to magnetic fields and x-rays. Local pickup at our location in downtown Los Angeles is suggested for sensitive items, if practical.
