Anders ( http://www.pdp-9.net/) designed a modern replacement for the G888. I tested it in my TC11 + TU56 and it mostly worked fine, except for in the far end of the tape where it performed worse than an original G888. It worked fine for booting RT-11 and XXDP but when you run the TC11 diagnostics it will give some errors while the original is error free. Anders is in the process of setting up a TU56 together with a TD8E right now to continue with this work to design a new card. I think all this is quite official since Anders has posted this thread on vcfed.org: http://www.vcfed.org/forum/showthread.php?63589-DEC-power-supply-725-going-hot-in-TU56H /Mattis > Noel >
