C ROM
Up to 8x 32Mbit ROMs (27C322) can be used for a maximum of 256Mbit C ROM. 27C800/27C160 can also be used depending on jumper config. Size of largest ROM is selected using a pair of jumpers. The rest should be left unconnected.
| ROM size | Jumper A | Jumper B |
|---|---|---|
| 8Mbit | J5 | J6 |
| 16Mbit | J7 | J8 |
| 32Mbit | J9 | J10 |
Pinouts
A NEO-273 and a LS74 are used to address C ROM. LS74 provides the 2 most significant bits. LS139 enables one of four pairs of C ROMs using 2 address inputs depending on which 2 jumpers are connected.
| Jumper | LS139 | LS74 | NEO-273 |
|---|---|---|---|
| J5 | 2(1A) | N/A | 45(A19) |
| J6 | 3(1B) | N/A | 46(A20) |
| J7 | 2(1A) | N/A | 46(A20) |
| J8 | 3(1B) | 9(Q2) | N/A |
| J9 | 2(1A) | 9(Q2) | N/A |
