Pending a company move, the whole setup was now set away for a few weeks. In the new lab I set about reassembling the stack. Which is when disaster struck ... The new magnifying glass setup was unstable and landed where it could cause maximal damage : the coremat itself, with around 40 cores broken........ Major major bummer, and really only myself to blame. Not only was the stack now lost, but I also now cannot produce evidence that the core repair worked.

The Fabritek has two known good coremat-pcb's, the Dataram has two potentially good coremat PCB's. I have spent rather too much time on this, and am open to offers on these stacks, in the condition described above. If someone wants to sell their known-defective 8L / 8I Dataram/Fabritek corestacks, I would also be interested. Jos Dreesen
