Adds an 8 MHz-or-faster Z80, 64 KB of onboard memory, and a beta CP/M environment through a 1090XL expansion slot.

The page reported one card in stock on 2026-07-27. CP/M customization and utilities remain late beta. The card is sold with or without a Z80; a user-supplied CPU must be rated for at least 8 MHz.

The exact page names only the 1090XL, so confirm 1091XL compatibility before using it in that implementation.
