- Specifications for the GoldenGate II Bridgecard
-
- SUMMARY
- -------
- The GoldenGate II bridgecard lets you lets you use AT-compatible IBM plug-
- in cards in your Amiga PC slots as Amiga devices, controlled by Amiga
- software. Software support currently includes drivers for PC serial and
- printer ports, with more exotic cards supported through the software emulator
- CrossPC (available with CrossDOS 5.0 from Consultron).
-
-
- PC HARDWARE SUPPORT
- -------------------
- The GoldenGate II bridgecard will support almost all non-DMA PC plug in
- boards which are "AT-compatible", i.e. can support 8 MHz bus accesses.
- This includes such popular items as internal modems, multi-IO
- boards, non-DMA ethernet boards, VGA boards, A/D boards, etc. Access
- to the PC cards is at full Amiga Zorro II bus speed unless wait state
- support is turned on.
-
- The following IBM AT bus signals are supported:
-
- IO address space from hex $0000 to $7FFF (first 32K)
- Memory address space from hex $90000 to $FFFFF (448K)
- 16 bit data bus
- All AT bus interrupts
- Wait states (IOCHRDY signal) for both IO and memory access
- 14.31818 MHz clock (OSC signal) from on-board crystal oscillator
- 7.2 MHz processor clock (CLK signal)
- BALE signal
-
-
- AMIGA HARDWARE DETAILS
- ----------------------
- The GoldenGate II bridgecard AUTOCONFIGs as a Zorro II card, and it
- can be "shut up" off the bus. The autoconfig size is 1 Meg to correctly
- map all of the PC memory locations. All address and data lines to the
- PC bus are buffered to avoid loading.
-
-
- ON-BOARD REGISTERS
- ------------------
- The GoldenGate II bridgecard includes 3 software accessable registers.
-
- Register 1 is read-only, and reports the status of all the interrupt
- lines, the master interrupt enable, and the wait-state control. This is
- a 16 bit register.
-
- Register 2 is read/write; when read, disables the master interrupt
- enable and returns the same 16 bit value as register 1. When register
- 2 is written to, it sets the master interrupt enable.
-
- Register 3 is read/write, and it toggles the support for wait states.
- When wait-states are enabled, a default of one wait state (one Amiga
- clock cycle) is inserted into each bus read or write to maintain IBM
- bus cycle wait state compatibility.
-
-
- SOFTWARE DRIVER SUPPORT
- -----------------------
- Due to a lack of standards in the IBM community, there is simply no way
- to provide Amiga software support for all possible plug-in cards.
-
- A small number of standards DO exist, however, and we will provide drivers
- for some of these, with more coming out whenever possible. The basic
- software package (compatible with the previous GoldenGate board) is for
- serial and parallel ports:
-
- ibmser.device a replacement serial device for internal modems and
- multi-IO cards. Includes automatic use of the 16550
- FIFO buffer when available. Support for up to 4
- serial ports at once, equivalent of COM1-4.
-
- SerPrefs set and save the intial settings of the IBM serial
- ports.
-
- ShowSerial prints out what serial chip is hooked to each IBM port
-
- ibmprint.device a new parallel output-only driver for printing through
- IBM LPT compatible parallel ports on multi-IO cards.
- Support for up to 3 printers at once, equivalent of
- LPT1-3.
-
- IOWedge a wedge program that allows redirection of serial and
- parallel port information to the IBM ports even from
- programs that do not alternate alternate device drivers.
-
- NewPortHandler this handler lets you use the new IBM ports directly
- from the CLI, by creating a mountlist entry. For
- example, you can mount IBMPRT: and then issue a
- CLI command to copy a file to the IBMPRT: device.
-
- Wait this is a small program to toggle wait state support
- on and off.
-
- All programs require AmigaDOS 2.0, and were written by Dan Babcock (thanks
- Dan!!).
-
- Details for accessing IBM IO and memory space through the GoldenGate II
- will be in the documentation. Most boards that do not try to emulate
- system functions (like ports) will not need device drivers; they can
- be accessed directly from your programs in C or any other high level
- language.
-
- For more exotic applications, the GoldenGate bridgecard is compatible with
- the software IBM emulator "CrossPC" sold by Consultron with CrossDOS 5.0.
- CrossPC will automatically find the GoldenGate bridgecard if it is
- installed, and map any IO location calls to the GoldenGate card.
- This allows you to use your IBM driver software directly. Thanks to
- CrossPC and IBeM author Mark Tomlinson for this!
-
- Author Chris Hames of PC-Task has also expressed an interest in
- putting similar GoldenGate compatibility into his emulator, and
- this should be available in the future.
-
-
- GOLDENGATE II SYSTEM REQUIREMENTS
- ------------------------------
- The GoldenGate II bridgecard occupies one Zorro II slot aligned with
- an IBM AT slot in an Amiga 2000, 2500, 3000, or 4000. It has essentially
- the same form factor as an XT bridgeboard. You will need at least one
- additional open PC-AT slot for your plug-in PC card.
-
- The GoldenGate II requires 1 Meg of autoconfig memory space to be
- available.
-
-
- AVAILABILITY AND PRICE
- ----------------------
- I am selling the GoldenGate II bridgecard in two ways:
-
- (a) As a kit with all parts and assembly instructions, for US$95
- (You should have some soldering experience
- to assemble this)
-
- (b) Fully assembled. for US$115
-
- Shipping charges will be US$3 within the US, US$5 to Canada, and US$10
- to anywhere else.
