Title: A4000 custom 1M kickstart eproms
Post by: AltRN8 on June 07, 2016, 03:04:55 AM

I'm trying to get a definitive answer to which eproms I can use to build a custom kickstart for an A4000 I am currently working on. I've googled a lot but most of what I've found indicates building our 512k kickstarts. If anyone can give me the specific model of eprom I need I'd be immensely grateful.

P.S. Yes I own legitimate 3.1 roms, OS 3.5, 3.9 and even 4 and 4.1 final edition (but no PPC accelerator, yet!)

It's been a really long time but I think an A4000 1M kickstart will fit in a pair of 27C400 eproms.

Do you also have a romy or other address decoding patch installed in your A4000?

If not, then no 1MB ROMs for you, the motherboard does not support it natively.
