Anywhere I should offer them up to? And how can I ID them if they don't list copyright data or have surviving paper labels?
There is something wrong with 'Amstrad 40044-1'.Dumped the HI/LO BIOS chips from my Sinclair PC500 (AKA AMSTRAD PC1512), here they are.
Oh, it's duplicated line-by-line? That's weird! I think that one failed a verify-check.There is something wrong with 'Amstrad 40044-1'.
( I see 40043-1/40044-1 ROM images hosted at [here], but they contain the code repeated four times [27256 in use?] )

Could I trouble you to provide a full list of those that need to be re-dumped? Alternately, I could just re-dump all of them, take a while though.
Edit: Actually, the cirrus-logic chip was read using the 64k and 128k profiles, that's why it's in the file-names. Not sure why they're so small.
Thank you kindly, that's very helpful!I had a quick look through, and these are the ones that appear faulty to me:
I'll check what size that chip is/should be if I can find a datasheet, maybe they just used an over-large chip and filled the unused space with junk?'IWS-4000 REL 2-0 EGA U55' (overdump? - 32K, should probably be 16K; the first 16 are junk)
Why are those two deemed too small? I'll check datasheets on them as well, if I can.'64V 3DX BIOS' (too small)
'Cardex1 VGA BIOS' (too small)
Those ones with the repeating characters just seem to have been programmed that way, maybe for a specific kind of testing?There's also the PC1512 which was already pointed out, and a few others which just contain the same repeating character, but you seem to have noted those in the filenames already ('A4' 'EA' etc).
Oh! That's likely the case, yeah. Guess I'll dump that one with the largest generic profile (for the number of pins) and see how that goes.The sizes would match up if "k" meant bits rather than bytes... just a thought.
