Krypton Regency (model 933)
6+
Krypton Challenge (model 5T-938)
77
88
It was manufactured by Timorite, Ltd. (Eric White's company), the chess engine is
99
by Gyula Horváth, similar to the one in CXG Sphinx Legend.

Hardware notes (Systema Challenge fitted with Regency MCU):
14-
- PCB label: LCD CHESS 938, JAN.1994, REV.1, EB-093801-01
15-
- Hitachi H8/3256 MCU, 20MHz XTAL
16-
- LCD with 5 7segs and custom segments
17-
- piezo, 16 LEDs (optional), button sensors chessboard
18-

A26 MCU was used in:
20-
- Krypton Regency (with or without LEDs)
21-
- Excalibur Avenger (suspected, Excalibur brand Comet, with newer MCU)
22-
- Excalibur Legend III (suspected, Excalibur brand Regency)
23-
- Systema Challenge (1996 version)

TODO:
2614
- CXG Sphinx Legend may be on the same hardware? if so, move driver to cxg folder
2715
- is Krypton a product brand, or a company alias for the Chinese factory behind it?
2816
- it does a cold boot at every reset, so nvram won't work properly unless MAME
2917
adds some kind of auxillary autosave state feature at power-off

Systema Challenge:
22+
- PCB label: LCD CHESS 938, JAN.1994, REV.1, EB-093801-01
23+
- Hitachi H8/325 or H8/3256 MCU, 20MHz XTAL
24+

25+
- piezo, 16 LEDs, button sensors chessboard
26+
27+
Krypton Regency (1995 version):
28+
- no main PCB label, LED PCB: TW933-E2, 996
29+
- Hitachi H8/325 MCU, 20MHz XTAL
30+
- rest is same as Challenge
31+
32+

The H8/3256 MCU has Krypton Regency's model number (933) on the label, though
39+
it was also used in Challenge.
