+Novag Super Sensor IV (model 812)
Novag Constellation (model 831)
+Novag Super Constellation (model 844)
-Hardware notes (1st version):
+The chess engine is by David Kittinger, Super Sensor IV is his first one
+working under Novag. The Constellation engine is completely different.
+
+Hardware notes:
+
+They are all on very similar hardware.
+The more expensive chesscomputers have battery-backed RAM and support for
+printer and chessclock peripherals.
+
+Constellation:
- MOS MPS6502A @ 2MHz
- 2KB RAM (daughterboard with 4*2114), 2*8KB ROM
- TTL, buzzer, 24 LEDs, 8*8 chessboard buttons
-3.6MHz version:
+Constellation 3.6MHz:
- G65SC02P-3 @ 3.6MHz (7.2MHz XTAL)
- 2KB RAM (TC5516AP), 16KB ROM (custom label, assumed TMM23128)
- PCB supports "Memory Save", but components aren't installed
+Super Sensor IV:
+- MOS MPS6502A @ 2MHz
+- 1KB battery-backed RAM (2*TC5514AP-3)
+- 8KB ROM (TMM2364P)
+- 2 ROM sockets unpopulated
+
+Sensor Dynamic's ROM is identical to Super Sensor IV, the hardware is basically
+a low-budget version of it with peripheral ports removed.
+
+Super Constellation:
+- UMC UM6502C @ 4 MHz (8MHz XTAL)
+- 4KB battery-backed RAM (2*TC5516APL-2)
+- 2*32KB ROM custom label
+
TODO:
-- add Quattro version, another small update, this time 4MHz
+- ssensor4 nvram doesn't work, at boot it always starts a new game
+- is Dynamic S a program update of ssensor4 or identical?
+- add Constellation Quattro version, another small update, this time 4MHz
