it's now dead.it spontaneously reset, then crashed after boot with a software failure message (red box flashing on back background with hex codes in side), clicking the mouse button to reboot then popped up the screen attached, and now (even after unplugging everything including the internal RAM expansion) on power on it just displays a black screen (signal is present) and the power light, but nothing happening, no "insert disk" screen, no clicking drive, nothing
dismantled my #amiga #a500plus to find out that the clock battery has leaked and caused some corrosion near the Gary chip, very similar to https://hackaday.com/2019/01/25/resurrecting-an-amiga-500/
I don't have the tools to repair it, unfortunately :(
It booted to the purple-background insert disk animation! Joy.
But then I got over-excited and plugged in the GVP HD8+ external hard drive and RAM expansion, back to the red bad ROM screen upthread. Then after unplugging it again the A500+ is now back to blank black screen (not no signal), no drive clicks. Back to where I was April 22nd.
So I guess the expansion is faulty in some way that (hopefully temporarily) messes up the state of the A500+ and makes it broke. Won't be plugging it in again any time soon.
