I have the same problems with a blizzard PPC@240/040@25. No boot, only a black screen, no access to the floppy, nor boot from HD.The HD led is permanet light on and the power led is on but with less light that normally.i try it without memory (could be that the problem?).I try it with a "naked" a1200 and on a tower 1200 with HD, cdrom, pixel64 gfx card and nothing.It´s also dead my blizzardPPC?? it´s a phase5 card
