Douglas's boards are good quality, but IMO their edge connector socket is inappropriate for DEC boards. It's not deep enough, it does make contact but on e.g. the extender cards, it doesn't provide enough mechanical support for the boards, like the old DEC extenders do. I suppose it's what we're stuck with for now, though. It'd probably be OK in a backplane with card guides. Their prototyping boards are also solid, I've ordered from them on several different projects. We now have our own DEC pattern quad height prototyping board, too: https://www.tindie.com/products/glitchwrks/gw-dec-1-prototyping-board-for-p… It's pad-per-hole, no edge connector pinning is assumed, so that it can be used on anything that takes DEC connectors (the need that prompted it was work on a VT05). The only annoyance with the Douglas protoboards is that some of them assume what's going to be power and ground, and you end up having to cut traces. Ours can also be sheared in half down the middle to make two dual-height cards. Thanks, Jonathan On Thu, Aug 13, 2020 at 10:33 AM Glen Slick via cctalk < cctalk at classiccmp.org> wrote:
