512kb expansion for the Amiga 500 Classic

Historic 512kb expansion for the Amiga 500 Classic which brings it to 1MB RAM in total (512k chip + 512k fast). Compatible with the latest revisions of the motherboard with Agnus 8372A with addressing up to 1MB RAM chip by removing the jumper on the expansion. Two versions available: without and with RTC (Real Time Clock) + alkaline backup battery The RTC chip is an Epson RTC62421A (or alternatively RTC62423A SOP28) perfectly compatible with the original OKI MSM6242 but unlike the latter, the Epson chip is much more accurate. The board is supplied fully assembled and ready for use. Easy installation through the lower door (trapdoor). There is no need to open the computer.
