-U2 Video chip with heatsink stuck on top, TMS9929
-U3 SN76489AN
-U4 2764 bios rom
-U5 uPD4016C-2 (assumed to be equivalent of 6116 2K x 8bit static RAM)
-U6 74LS04

-
-SD-BASIC usage:
-All commands must be in uppercase, which is the default at boot.
-The 'capslock' is done by pressing Shift and Esc together, and the
-cursor will change to a checkerboard pattern.
-
-The above key combination is not available to natural keyboard, so
-press ~ instead. Natural keyboard & Paste assume this has been done,
-to enable lowercase.
-
-
-MEMORY MAP
-0000-1FFF bios rom
-2000-5FFF available for expansion
-6000-7FFF static RAM (2K mirrored)
-8000-FFFF cart slot
-
-The 16k dynamic RAM holds the BASIC program and the video/gfx etc
-but is banked out of view of a BASIC program.

-ToDo:
-- Joysticks (no info)
