- Cartridge: 4KB
- 8048: 1KB (BIOS)
- COP411L: 512bytes
Graphics
- 解像度は150x40
- 垂直方向に赤色LEDが40個並んでいる。（8個×5セット）
- 水平方向の映像は回転式ミラーによる残像を利用して生成している。
  - 450rpm (1秒間に7.5回転)
  - 1回転で2frame生成するので15fpsということになる。

P2.4=0のときにExternal RAMをreadすると、readしたデータが選択中のLED Bankに書き込まれる（らしい）。
External RAMからLEDへの転送はBIOS $03で行われているので通常使用することは無い。
- BIOS $03では、ミラーの回転と同期してかなりシビアなタイミングで転送が行われている。
各bitは0で点灯、1で消灯。
Bank内でのLEDとbitの対応は今のところ不明。

VRAM

External RAMのBank#1~3の$06~$FFをVRAMとして使用する。
- 各バンク250バイト*3 = 150*(40/8)バイト = 750バイト
各bitは0で点灯、1で消灯。
- BIOSで描画する場合は、BIOS内部でnotしているので用意するデータは0で消灯、1で点灯でかまわない。
