| 188 | 188 | *Devices of interest: |
| 189 | 189 | J1: breakout of joystick, serial/rs232, hex-keypad, parallel port, and forth switch (and maybe cassette?) pins |
| 190 | Jx: 4 pin on top side, 6 pin on bottom side edge ?debug? connector (may have been intended to be J2, doesn't actually have a J number at all) |
| 191 | J3: Floppy Connector (standard 34 pin shugart) |
| 190 | 192 | J4: keyboard ribbon cable |
| 193 | J5: Berg type socket for supplying power (5v gnd gnd 12v) to the floppy drive |
| 194 | J6: Phone connector, rj11 jack |
| 195 | J7: Line connector, rj11 jack |
| 196 | J8: Video out/power in |
| 197 | J9: solder points for a rom expansion/replacement daughterboard, not populated |
| 198 | E1: jumper, unknown purpose |
| 199 | E2: jumper, unknown purpose |
| 200 | D13: LED |
| 191 | 201 | R6522P (upper): parallel port via |
| 192 | 202 | R6522P (lower): keyboard via |

| 203 | 213 | 4N37 (marked on silkscreen "4N35") |
| 204 | 214 | 74F153 (marked on silkscreen "74ALS153") |
| 215 | 74HCT259 is socketed, possibly intended that the rom expansion daughterboard will fit in its socket and in place of the 2 roms, if populated |
