Eeproms I Found....

Methanoid · 11 June 2019, 18:45

Tidying up and finding all the things I bought and never did projects with and found

27C1024 Eeproms 15F1 (10 of these!) [are these for 512k Kickstarts???]
AMD 27C400 120DC - (2 of these) [these must be single 512k Kickstart use]
27C800 (just one) [pretty sure this is for a dual Kickstart use]

I am wondering if these were for Kickstart (or TOS) switchers or are suitable for just a single use Kickstart (or TOS)

Anyone know? Anyone got a burner?

27c400 is useful for kickstarts.. 27c800 can also be used either as a multi rom or perhaps a 1MB kickstart on some machines.

Thanks... I now need to find someone with a burner.. Any idea why I would have bought the others? Atari ST TOS maybe?

All the TOSes I've burned went on much smaller EPROMS, but I don't claim to have seen every possible Atari computer. :-)

27C400x2 can be used in A4000 as a 512kb, you just have to double the split images. Or use a Romy for a 1MB Kickstart.

I've got a great Wellon programmer. Unfortunately I'm pretty sure I'm also on the other side of the world.
