Sonnet L2 Cache Card 300/512k - upgrade cache to 1m?
Posted by: Trekintosh on 2025-02-09 21:12:40 Hey gang, I just won the above upgrade card on eBay for my pimptastic 5500, and I was wondering if I could upgrade the cache by adding the missing chips to the board, or if there’s a ROM or similar on the board that will prevent this. Also, could someone upload a pic of the backside of one of these cards with a fully populated cache(and if you’re super generous the front side under the heat sink) so I can find out which chips I need? P.S. I know I have 3 threads up on this subforum now. I’m trying to keep my main question topics separated so people of the future (probably me when I get old and forget let’s be real) can find them on Google.
