I've been going through trying to determine the state of a few of my machines recently (all have recapped logic boards), and I've noticed a sporadic oddity when shutting down, and I don't know if it's related to a logic board issue, something to do with the aged HDD or even the PSU. If you look at the attached photo, you'll see that the 'safe to shutdown' screen is missing a bunch of letters. It doesn't happen every time I shut down, but it is relatively frequent. Any idea what could be causing this? Faulting ROM chips? RAM? VRAM? It's just a bit of a mystery to me. It's happened on both an LC III and my one (sort of) working 475. Mind you, I was swapping the HDD between them, and I will be testing a new PSU later today (mAcTX for LC with Pico PSU) and swapping in a SCSI2SD drive solution tomorrow.
