Host Invaders (c) 1998 The Game Room
driver by Angelo Salese & Grull Osgo
Hardware is known as "AUSCOM System 1" hardware.
Other games known to be on this hardware (if ever finished):
- Agro (c) The Game Room
- Tiger Odds (c) The Game Room
- one other unnamed/unfinished game
Notes:
- calchase: type boot to load game
TODO:
- get Win 98 to boot (most of Windows 98 copy is damaged inside current HDD dump);
- Various graphics bugs (title screen uses ROZ?);
- fix 129 Hz refresh rate bug;
- inputs (is there a service mode?)
I/O Memo (http://bochs.sourceforge.net/techspec/PORTS.LST):
46E8 ---- 8514/A and compatible video cards (e.g. ATI Graphics Ultra)
46E8 w ROM page select
83C0-83CF ---- Compaq QVision - Line Draw Engine
83C4 ---- Compaq Qvision EISA - Virtual Controller Select
83C6-83C9 ---- Compaq Qvision EISA - DAC color registers
43c4 is a 83c4 mirror?
=====================================================================================
California Chase
The Game Room, 1999
This is a rip off of Chase HQ running on PC hardware
and standard 15kHz arcade monitor
Main board is a cheap Taiwanese one made by SOYO.
Model SY-5EAS
Major main board chips are....
Cyrix 686MX-PR200 CPU
1M BIOS (Winbond 29C011)
64M RAM (2x 32M 72 pin SIMMs)
ETEQ EQ82C6617'97 MB817A0AG12 (QFP100, x2)
UT6164C32Q-6 (QFP100, x2)
ETEQ 82C6619'97 MB13J15001 (QFP208)
ETEQ 82C6618'97 MB14B10971 (QFP208)
UM61256
PLL52C61
SMC FD37C669QF (QFP100)
3V coin battery
3x PCI slots
4x 16-bit ISA slots
4x 72 pin RAM slots
connectors for COM1, COM2, LPT1, IDE0, IDE1, floppy etc
uses standard AT PSU
Video card is Trident TGUI9680 with 512k on-board VRAM
Card is branded "Union UTD73" - these are all over eBay, for instance
RAM is AS4C256K16EO-50JC (x2)
Trident BIOS V5.5 (DIP28). Actual size unknown, dumped as 64k, 128k, 256k and 512k (can only be one of these sizes)
6.5536MHz xtal
Custom JAMMA I/O board plugs into one ISA slot
Major components are...
XILINX XC3042
Dallas DS1220Y NVRAM (dumped)
MACH210 (protected)
16MHz OSC
VGA connector (tied to VGA card with a cable)
2x 4-pin connectors for controls
AD7547
ULN2803
LM324 (op amp)
TDA1552 (power amp)
ST TS272 (dual op amp)
2 volume pots
power input connector (from AT PSU)
JAMMA edge connector
ISA edge connector
HDD is WD Caviar 2170. C/H/S = 1010/6/55. Capacity = 170.6MB
The HDD is DOS-readable and in fact the OS is just Windows 98 DOS and can
be easily copied. Tested with another HDD.... formatted with DOS, copied
all files across to new HDD, boots up fine.
Host Invaders is the same motherboard and video card as above, but instead of an HDD,
there is a CD-ROM drive.

/*
Grull Osgo - Improvements
-Changes about BIOS memory management so ROM Shadow now works properly.
The changes are:
Rom Memory Map remmapped to 128K size map(0xfffe0000, 0xffffffff).rom().region("bios", 0);
-Changes in mtxc write handler and bios_ram write handler. Now The internal register access are
compatible with chipset VIA.
(this motherboard has VIA Apollo VXPro chipset. It is not compatible with Intel i430).
With this changes now BIOS Shadow ram works fine, BIOS can relocate and decompress the full code
necesary to run the Extended Bios, POST and Boot). No more BIOS Checksum error.
- Suppressed all video related items wich will be replaced with VGA driver.
- Temporarily added a VGA driver that is working based on original IBM VGA BIOS.(From MESS)
(This VGA driver doesn't work yet with TRIDENT VGA BIOS as I can see).
- Added the flag READONLY to the calchase imagen rom load function, to avoid
"DIFF CHD ERROR".
- Minor changes and NOPS into address maps for debugging purposes.
- Now Bios is looking for the disk (BIOS Auto detection). It seems all works fine but must be there
something wrong in the disk geometry reported by calchase.chd (20,255,63) since BIOS does not accept
255 heads as parameter. Perhaps a bad dump?
TODO: A lot of work to do yet!!!
- update by peter ferrie:
- corrected memory map to 64kb blocks
- corrected access to PAM register
