/******************************************************************************************
PC-XT (c) 1987 IBM
(Actually Arcade games running on more or less modified PC-XT HW)
driver by Angelo Salese & Chris Hardy
original tetriunk.c by David Haywood & Tomasz Slanina
Notes:
- The Korean Tetris is a blantant rip-off of the Mirrorsoft/Andromeda Software Tetris PC
version;
TODO:
- 02851: tetriskr: Corrupt game graphics after some time of gameplay, caused by a wrong
reading of the i/o $3c8 bit 1. (seems fixed?)
- Add a proper FDC device.
- Filetto: Add UM5100 sound chip, might be connected to the prototyping card;
- buzzer sound has issues in both games
********************************************************************************************
Filetto HW notes:
The PCB is a un-modified IBM-PC with a CGA adapter & a prototyping card that controls the
interface between the pc and the Jamma connectors.Additionally there's also a UM5100 sound
chip for the sound.
PCB Part Number: S/N 90289764 NOVARXT
PCB Contents:
1x UMC 8923S-UM5100 voice processor (upper board)
1x MMI PAL16L8ACN-940CRK9 (upper board)
1x AMD AMPAL16R8APC-8804DM (upper board)
1x AMD P8088-1 main processor 8.000MHz (lower board)
1x Proton PT8010AF PLCC 28.636MHz (lower board)
1x UMC 8928LP-UM8272A floppy disk controller (lower board)
1x UMC 8935CS-UM82C11 Printer Adapter Interface (lower board)
1x UMC 8936CS-UM8250B Programmable asynchronous communications element (lower board)
There isn't any keyboard found connected to the pcb.
********************************************************************************************
Filetto SW notes:
The software of this game can be extracted with a normal Windows program extractor.
The files names are:
-command.com (1)
-ibmbio.com (1)
-ibmdos.com (1)
-ansi.sys (1)
-config.sys (2)
-autoexec.bat (3)
-x.exe (4)
(1)This is an old Italian version of MS-DOS (v3.30 18th March 1987).
(2)Contains "device=ansi.sys",it's an hook-up for the graphics used by the BIOS.
(3)It has an Echo off (as you can notice from the game itself) and then the loading of the
main program (x.exe).
(4)The main program,done in plain Basic with several Italian comments in it.The date of
the main program is 9th October 1990.
