| 4 | Game probably programmed by same people behind some Kyugo/Orca/Komax games (see hiscore table, Gyrodine pinout, clocks etc.) |
| 5 | |
| 6 | Upper board marked DVL/A-V |
| 7 | Bottom Bord DVL/B-V |
| 8 | |
| 9 | The pcb seems a bootleg/prototype: |
| 10 | On the upper board there are some pads for jumpers , some empty spaces left unpopulated for additional TTLs and an XTAL. |
| 11 | All 5 sockets for 2732 eproms were modified to accept 2764 eproms. |
| 12 | The AY8910 pin 26 (TEST 2) is grounded with a flying wire |
| 13 | |
| 14 | Upper board chips: |
| 15 | 5x 2764 eproms |
| 16 | 1x 2128 static ram (2k ram) |
| 17 | 2x z80B |
| 18 | 1x AY8910 |
| 19 | 2x 8 positions dipswitches |
| 20 | |
| 21 | Bottom Board chips: |
| 22 | 5x 2764 eproms |
| 23 | 2x 2128 static ram (2kx8 ram) |
| 24 | 4x 93422 DRAM (256x4 dram) |
| 25 | 1x 6301 PROM (probably used for background ?) |
| 26 | 3x 82s129 Colour PROMS (connected to resistors) |
| 27 | |
| 28 | Clocks measured: |
| 29 | |
| 30 | Main XTAL 18.432mhz |
| 31 | 2x z80 : 18.432 / 6 |
| 32 | AY8910 : 18.432 / 12 |
| 33 | Vsync : 60.58hz |
