/* Unknown - Poker (morugem

driver by Roberto Zandona'
thanks to Angelo Salese for some precious advice

TO DO:
- check sound

Anno: 1982
Produttore:
N.revisione:

CPU:
1x unknown DIP40 (1ef)(missing)
1x TBA820 (14e)(sound)
1x oscillator 12.000 (2f)

ROMs:
2x TMS2532 (5b,5e)
1x TMS2516 (8b)
1x PROM SN74S288N (8a)
1x RAM MWS5101AEL2 (11e)
4x RAM AM9114EPC (2b,3b,8e,9e)

Note:
1x 22x2 edge connector
1x trimmer (volume)
1x 8x2 switches dip
