Video Controller Circuit
(1) CPU
block
CPU(#33) MB86832-100 manufactured by Fujitsu
RISC chip
Clock speed: 33.1768 Mhz (3 times faster than the base clock)
Appearance: 178-pin QFP
Voltage: 3V
(2)
ASIC/Gate Array Block
•
#19 MB87F1611(Fujitsu) - 240-pin QFP
Controls the address decoder, timers and interfaces (Centronics and RS-232C).
•
Controls HRC(High Resolution Control), GSC(Gray Scale Control) and
economy mode, drivened by 3V.
•
#2 µPD65632GC - 100-pin QFP
Controls the I/O ports and others.
(3)
Font Card Block
•
Font Card (option)
The font card has a 64MB memory area and is controlled by the 16-bit bus.
The card is supplied with 12V power in the slot 2 because the PCMCIA card
requires 12V power supply when writing or erasing data.
The address bus is buffered by LS245 and the data bus, is buffered by
LCX245.
(4)
Centronics/RS-232C interface block
•
Centronics parallel interface
Data transmission and reception are controlled by the MB87F1611 (#19).
•
RS-232C
Data transmission and reception are controlled by the MB87F1611 (#19).
The ADM202JRN (#35) serves as driver/receiver.
(5) SIMM
block
•
SIMM (Single-Inline-Memory-Module) allows memory extension up to 72MB
•
2 SIMM sockets are available.
•
SIMM should be of 72-pin type and its access time should be less than 70 ns.
•
12 types of SIMM (1MB, 2MB, 4MB, 8MB, 16MB and 32MB) can be combined:
1MB MH25632BJ-7 (MITSUBISHI), HB56D25632B-7A (HITACHI)
2MB MH51232BJ-7 (MITSUBISHI), HB56D51232B-7A (HITACHI)
4MB MH1M32EJ-7 (MITSUBISHI), HB56A132BT-7A (HITACHI)
8MB MH2M32EJ-7 (MITSUBISHI), HB56A232BT-7A (HITACHI)
16MB THM324000BSG-60, -70, -80 (TOSHIBA)
32MB THM328020BSG-60, -70, -80 (TOSHIBA)
Note:
Fast page type and EDO type can be used together although it is not
recommended.
1) The SIMMs have its printed marking on the PCB by silk screen: SLOT1 and
SLOT2, respectively.
2) The attached Printer SIMM map shows the memory map for 4 SIMMs combined.
