Things have taken a turn for the better thanks to my pals at MNE. They fixed the problem, a faulty power brick, in no time. Thanks Jordan and Stefano!
Time hasn’t been very kind to the A1200’s internal HDD. The drive is kaput – most likely a problem with the controller. Source code and assets from later projects are now gone, including my last big project on the Amiga: a Street Fighter 2 clone. Fortunately, Blaze was pre-A1200, so I still have all the stuff on floppies. Patrick, our go to guy from IT Services, has kindly offered to replace the faulty HDD with a 2GB one he had salvaged from a dead laptop. The new HDD will save me tons of diskette swapping, so thanks Pat!
