+
+ Computer kindly donated for MAME by Ian Farquhar.
+
+ Accessories:
+ - PEN-216 : 16k RAM expansion
+ - PEN-264 : 64k RAM expansion
+ - PEN-511 : Data Cassette Recorder
+ - ??? : Printer
+ - ??? : Floppy Disk Drive (5.25)
+ - ??? : Floppy Disk Controller
+ - ??? : RS-232C Serial Interface
+ - ??? : Coleco Adapter*
+ - PEN-8xx : Various software on Cassette or Floppy Disk
+ - ??? : Game Controller (joystick and 14 buttons)
+ - PEN-7xx : Various software in Cartridge format
+ - PEN-430 : Modem
+ - PEN-902 : Computer power supply
+ - PEN-962 : Monitor cable
+
+ * The cart slot is the same as that found on the Colecovision console. By plugging the

+
+Information found by looking inside the computer

+Main Board PEN-002 11-50332-10
+
+J1 Expansion slot
+J2 Cart slot
+J3 Memory expansion slot
+J4 Printer slot
+J5,J6 Joystick ports
+
+XTAL 10.738 MHz
+
+Output is to a TV on Australian Channel 1.

+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.
