   There are five sockets in a row (IC71 - IC75) but IC 75 is empty. IC 71 is an EPROM but the label in missing. IC 72 is a Hitachci PROM marked HN613128PD11 View2-1 Japan (c)ACORNSOFT, IC 73 is an EPROM and is marked DNFS 201666, IC 74 is an EPROM and is marked US BASIC 201667. Behind that row is IC 52, it's marked VI (I THINK, it's stylized and hard to read), then 403 V 2006 VC 2023 201647 (c)ACORN COMPUTER KOREA-AE. I think that's all of the custom ICs.

    Hmm. Sounds like it's not finishing the boot sequence.
