# WRx16 Version 2

Тһе WRX16 core that we published in 4:2 works fine with the usual 16К RAMpack on a ZХ81/TS1000. It also works, with two restrictions, on most 64K packs. The first is that the dynamic RAM should preferably be switchable in the 8-16К region. This restriction still exists on the new version; we can’t do much about that. However, even some RAMs that can‘t be switched out here, will work in spite of the apparent conflict.
