Amiga 500 memory expansion battery. The latter is a bit of a concern as everybody on YouTube almost begs to remove and or replace the battery. This product is manufactured by Amiga Kit offering high quality upgrades for your Amiga computer at good value, low prices. System RAM will be increased from the standard 0. The chip is an Epson RTC72421A or RTC72421B. I am the proud owner of three Amiga's 2x 1200 and a 500. This is the perfect complement to our Terrible Fire 534 Accelerator for Amiga 500. After dissembling the Amiga I would suggest using a pair of side cutters to snip the foot posts from each side of the battery where it meets the motherboard. It doubles Amiga 500 memory from 0. Untested, Battery Removed We do offer combined shipping. It has a memory board and a Gary adapter (for extra address signals). 1hu gwokx 1uvcp vc3 kjtl8 h1wolh igj wpqqic6r ghsovf qyi
