-
-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?)
-- tetriskr can store inputs read during the timer irq. If ds is 0x40 when the irq is taken
- it will corrupt the BIOS data area which can lead to corrupt graphics
-- Add a proper FDC device.
-- 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)
-1x UMC 8937NS-UM82C8167 Real Time Clock (lower board)
-1x Yamaha V6363 CMDC QFP (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.
