|

Olympia Olytext 20 Screen-Typing System
|
||||
Made in Germany
|
||||
|
||||
Major Chips: Z80A, Z80PIO x2, Z80SCC, WD1772, National Semiconductor NS405-B18N
|
||||
Crystals: 16.000, 18.000
|
||||
Piezo-Beeper
|
||||
RAM: 128k dynamic (16x 4164), 8k static (4x MB8128-10)
|
||||
Keyboard: 3870 with 4.000 crystal, 3 dipswitches
|
||||
|
||||
The NS405 is a Terminal Management Processor which provides complete video functionality.
|
||||
It is modelled on the 8048, and requires an external rom. All other functions (cpu, timing,
|
||||
character generation, uart, dma, crtc, etc) are internal. Data is sent to it in parallel
|
||||
from the pio, something like a printer, but there's no handshake. Apparently the TMP is
|
||||
fast enough to accept all data as it arrives.
