If you send me a picture of the backplane part of the box (without the outer shroud), I might be able to help. I think I have some 4x4 Qbus backplanes, which are likely to be Q16 or Q18 not Q22 that have no box but may be the former contents of a BA11-M. I know they aren't part of a BA11-N, because I have 2 of those that I use with RLV11s. The paper tag on the backplane says "LSI-11" (the type of tag that might say DD11-CK or DD11-DK when applied to those backplanes). > If so, does anyone have spare MSV11-DD 64kb memory and DLV11 type serial > cards for sale/trade? I think those cards are easy to find. Among the most common Qbus cards. I have some, as do others on this list. -ethan
