| 10 | Uses Texas Instruments parts and similar to other TI computers. |
| 11 | It was designed by TI engineers, so it may perhaps be a clone |
| 12 | of another TI or the Geneve. |

| 14 | Video chip is TMS9928 or TMS9929. |
| 15 | |
| 16 | 64K RAM. |
| 17 | I saw somewhere that the roms are copied into ram at startup. |
