+    If you want to "own" this, go ahead, it's yours.
+
+    Olympia Olytext 20 Screen-Typing System
+    Made in Germany
+
+    Major Chips: Z80A, Z80PIO x2, Z80SCC, WD1772, National Semiconductor NS405-B18N
+    Crystals: 16.000, 18.000
+    Piezo-Beeper
+    RAM: 128k dynamic (16x 4164), 8k static (4x MB8128-10)
+    Keyboard: 3870 with 4.000 crystal, 3 dipswitches
+
+    The NS405 is a Terminal Management Processor which provides complete video functionality.
+    It is modelled on the 8048, and requires an external rom. All other functions (cpu, timing,
+    character generation, uart, dma, crtc, etc) are internal. Data is sent to it in parallel
+    from the pio, something like a printer, but there's no handshake. Apparently the TMP is
+    fast enough to accept all data as it arrives.
