This is a long shot, but: I got a bare H9273 backplane (9-slot Qbus, 18-bit) off a fellow list member. It's been languishing in my parts area for a while while I try to figure out what to do with it. If someone happens to have a bare card cage that fits it (I think it's mechanically identical, or at least compatible, to the H9276), I'd be much obliged and would pay a reasonable sum of money for it. I don't need a full H9273 backplane/cage assembly, since my entire intent is to make use of the backplane I have. Otherwise, if anyone has any experience designing and fabricating card cages on the cheap, I'd be interested. I initially considered doing something out of wood, since I don't have much in the way of metalworking tools, but that presents some obvious airflow issues. It's still looking like the best option for me if I just cut the sides away aside from some columns for mounting the plastic card guides. - Dave
