Meanwhile, the #PERQ has broken once again. A problem somewhere on the EIO board again, affecting floppy and hard drive both, but only after some data have been loaded from them. DDS=157 or 158 on HDD or FDD boots of POS respectively. PERQs gonna PERQ...
Handy: it looks like it works fine to replace a PAL16R8 with a GAL16V8 (at least a GAL16V8D, -15) as the DCD2 chip on a #PERQ 2T2's DIB.
I was able to reuse the old, singed DCD2 label from the original PAL... which I might have plugged in backwards one day...
