(MESS) pasogo.c: Added readme. [Guru]
Out of whatsnew: I only fixed the cpu main clock. Changing the 80188 to V30 also requires redoing the address maps.

|
|
||||||
|
VG230 - Vagem VG230 single-chip PC platform. Contains 16 MHz NEC uPD70116H V30HL CPU
|
||||||
|
(which is a high-speed low-power 8086 variation), IBM PC/XT-compatible core
|
||||||
|
logic, LCD controller (CGA/AT&T640x400), keyboard matrix scanner, dual PCMCIA
|
||||||
|
2.1 card controller, EMS 4.0 hardware support for up to 64MB, built-in timer
|
||||||
|
PIC/DMA/UART/RTC controllers. The clock input is 32.2200MHz. An internal divider
|
||||||
|
creates a 16.11MHz clock for the V30HL CPU.
|
||||||
|
HM514800 - Hitachi HM514800 512k x8-bit DRAM
|
||||||
|
MC14071 - Motorola MC14071 Quad 2-input OR gate
|
||||||
|
74HC04 - 74HC04 Hex inverter
|
||||||
|
LM2937 - Texas Instruments LM2937ES-5 voltage regulator (Max 26V input, 5V output at 500mA)
|
||||||
|
CE-0702 - TDK CE-0702 DC-DC converter for LCD in SIP9 package (5V input, -24V output at 25mA)
|
||||||
|
POWER - 9V DC power input from AC/DC adapter
|
||||||
|
VOL - Volume pot
|
||||||
|
CN5 - 5 pin connector for 4-way control pad (up/down/left/right/ground)
|
||||||
|
CN4 - 5 pin connector for on/off switch and 2 buttons
|
||||||
|
CN3 - 2 pin power input from 6x AA-battery compartment (input voltage is 9V DC)
|
||||||
|
CN2 - Flat cable connector for video out to LCD panel. When the LCD is powered on the pixels
|
||||||
|
are blue. The LCD panel PCB has part number 97-44264-8 LMG6912RPFC LMG6910RPGR
|
||||||
|
and contains the following parts.....
|
||||||
|
Matsushita 53008HEB-8
|
||||||
|
Sanyo LA6324N quad operational amplifier
|
||||||
|
Hitachi BD66285BFC LCD controller IC (x3)
|
||||||
|
Hitachi BD66284BFC LCD controller IC (x4)
|
||||||
|
The LCD flat cable has several wires but 2 of them have frequencies which measure
|
||||||
|
69.9161Hz and 16.7798kHz. These are assumed to be VSync and HSync
|
||||||
|
CN1 - Cart slot
|
||||||
|
X1 - Marked 322. Measures 32.21732MHz so this is a common 32.22MHz OSC.
|
||||||
|
X2 - No markings. Measures 32.768kHz and used for the RTC
|
||||||
|
* - These parts are on the other side of the PCB
|
||||||
|
|
||||||
|
|
||||||
|
Carts
|
||||||
|
-----
|
||||||
|
All of the carts are identical. Most have only one surface mounted mask ROM. Either a
|
||||||
|
MX23C8100 (8M) or YRM0442 (4M). Some are populated with additional parts including a 62256
|
||||||
|
32kx8 SRAM, a 3v coin battery and a MM1081N reset chip plus a few resistors/capacitors and
|
||||||
|
a transistor. All parts are surface mounted.

Notes:
|
||||||
|
Carts containing just one mask ROM are KS-1002, KS-1003, KS1004 and KS-1009
|
||||||
|
Carts containing RAM, battery and reset chip are KS-1001 and KS1010
|
||||||
|
Carts KS-1005, KS-1006, KS-1007 and KS-1008 probably exist but are unknown.
