1 month ago Hi There,
Nice to hear you like the project and would like to build one. This makes me really happy! As for your questions;
- IDE support will work on a regular A500 - that is what I have. You need to create a custom kickstart, checkout the guide I just posted called KICKSTART.md in the repo root. This should help with creating one for yourself.
- Check out this issue - https://github.com/PR77/A500_ACCEL_RAM_IDE-Rev-2/issues/4#issue-833610784. The SPI EEPROM is not needed for the card to function.
- You can use other SRAM chips, just make sure there are at least 55ns or faster. This will ensure best performance.
Hi there!
I'm looking to build one of these :)
Few questions please:
Will IDE support work on the regular (non plus) A500? Should kickstart be updated, and if so to which version?
I would like to understand if the U104 flash EEPROM needs to be populated on the board? I believe there is a sentence in readme saying support for kickstart roms? Was support for this implemented in v2? if so, what exact chip size / model should I be using?
For SRAM_512Ko ICs, I believe in another post you recommended AS6C4008-55PCN? Are there any other alternatives to use for RAM chips?
Thank you :)
