for the 8008 in this application?
As far as I know only the 2640 and 2644 used the 8008.
Some HP p/n from those Terminals:
1820-1219 TR 1602 B USART
1820-1221 D 8008-1
1820-1288 MMH 0026 CL two phase MOS Clock Driver
1816-0612 MMI : Char. Gen. Roman upCase [24] Terminal 2644 A
1816-0613 MMI : Char. Gen. Roman loCase [24] Terminal 2644 A
Firmware ROMs
1818-0157 EA 4900 masked Terminal 2644A
1818-0158 EA 4900 masked Terminal 2644A
1818-0159 EA 4900 masked Terminal 2644A
1818-0160 EA 4900 masked Terminal 2644A
1818-0161 EA 4900 masked Terminal 2644A
1818-0162 EA 4900 masked Terminal 2644A
1818-0176 EA 4900 masked Terminal 2644A
Those numbers come from my own terminals. Other 2644 may have newer
firmware ROMs with other partnumbers. There were also different
interface cards with maybe different USARTs.
Also I don't know, if for example ROMs of same types and maskrevisions
but different manufacturers (EA, Mostek, MMI) had different partnumbers.
