| 10 | * The Prose 2000 card is an IEEE 796 Multibus card, with additional connectors to facilitate power and serial input other than via multibus. |
| 11 | * There are two hardware versions of the card: |
| 12 | * - The 1981 Telesensory Systems Inc copyrighted version |
| 13 | * (lacks U82, has some rework on the power input to add a bypass capacitor and an extra power line to the 8086) |
| 14 | * - The 1986 Speech Plus copyrighted version |
| 15 | * (adds U82 as an extra buffer for status (not sure)? integrates the greenwire fixes from the above board, minor reorganizations of passives) |
| 16 | * Both versions encountered have been in non-multibus enclosures: |
| 17 | * - The 1981 Version appeared on a 'Voice V4' Speech board scrapped from a "Kurzweil Reading Machine" Talking Scanner (predecessor to the TSI/Kurzweil/Xerox 'Reading Edge' scanner which is SPARC based) [I'm very sorry I didn't get the OCR computing guts of the scanner itself too :( ] |
| 18 | * - The 1986 Version appeared in a 'Prose 2020' under-monitor RS232 speech unit. |

|---|
| 57 | 45 | * 8259 PIC: figure out where IR4-7 come from, if anywhere. |
| 58 | 46 | * UPD7720 and 8259: hook up p0 and p1 as outputs, and figure out how 8259 IR0 is masked from 7720 p0. |
| 59 | 47 | * Add other dipswitches and jumpers (these may actually just control clock dividers for the two 8251s) |
| 48 | * Older v1.1 set gets stuck forever waiting for upd7720 status port to equal 0x20, which never happens. |
| 60 | 49 | * Everything else |
| 61 | 50 | * |
| 62 | 51 | * Notes: |
| r32191 | r32192 | |

| 80 | 69 | * When the unit is idle, leds 5 and 3 are on and upd7720 reset is low (write of 0b?1?0101?. |
| 81 | 70 | * On all character writes from i8251, bit 8 is unset, then set again, possibly to avoid interrupt clashes? |
| 82 | 71 | * |
| 83 | | * Bootup notes: |
| 72 | * Bootup notes v3.4.1: |
| 84 | 73 | * D3109: checks if 0x80 (S4-8) is set: if set, continue, else jump to D3123 |
| 85 | 74 | * D3123: write 0x1C (0 0 0 [1 1 1 0] 0) to 3401 |
| 86 | 75 | * then jump to D32B0 |
