Potential PVR Mobo
3 messages in this thread
Hey Guys…
Here's some specs on a mobo that _might_ be a good one for building a PVR
station around. I came across it a week or two ago, but I haven't pursued it
any further. The board is called the "ZAPPA OEM: M505 TRITON" and it's sold by
Micromax (Tel: 800-795-6299):
* Intel Triton PCIset chipset. * Supports 75-133MHz Pentium P54C & P54CS CPUs
w/320 pin ZIF socket. * Uses 72-Pin SIMM modules x4 auto backing in multiple
configs to 128MB. * Supports both fast page mode and extended data output (EDO)
DRAM modules. * High performance L2 write-back cache supports pipeline burst
SRAM (256KB
only) or asyncronous SRAM (256KB or 512KB). * 4 PCI slots, and 4 16-BIT ISA
BUS slots (all slots support master mode). * System BIOS supports 4IDE HDD
drivers up to 8.4Gb. * PCI master IDE interface on board with 2 connectors for
4 IDE devices in 2
channels, the PCI IDE controller supports PIO Mode 3 and 4 at maximum
transfer rates of 16.67 MB/s and Bus master IDE DMA Mode 2 at max of 22MB/s.
* On-Board "Multi-I/O" using the UMC UM8663 super Multi-I/O chip that
supports 2 serial ports, 16550 Fast UART compatible, 1 parallel port with
EPP and ECP capabilities, and a floppy disk drive connector that supports
drives up to 2.88MB. * System BIOS supports NCR810 SCSI BIOS firmware and
green feature function. * Current MO Price for the mobo w/133 MHz Pentium is
$959 (+$75 for 512K
cache, Syncronous Cache available Sep '95).
When I talked with the MO person at Micromax, he stated that the motherboard is
made under Intel license in Taiwan, and that it's about $100 cheaper than a
conventional ZAPPA. The schematic he sent me shows three (3) of the four PCI
slots as appearing to be 100% clear for use with full-length cards. located
between the PCI slot group and the ISA slot group. There are two connectors for
COM1 & COM2 in that same area. Only one PCI slot looks like it would be
unuseable with a full-length PCI card. I was told that the I/O is serviced thru
a conventional ISA-BUS board, so users would have to plan on giving up one ISA
slot to I/O functions. I haven't seen this board in person, nor do I know if
the specs are as good as other competitors boards, but I thought some of you
would be interested if you intend to build your own box from the ground up.

Mike,
Interesting info. That board doesn't sound at all like the Intel Zappa,
even the OEM versions that Intel sells. I wonder why they're using the name,
since the specs seem so different.

Well, my guess is that Intel has licensed the "ZAPPA" and "TRITON CHIPSET"
names to the manufacturer. All that means is the board has to perform like it
was a Zappa/Triton board made by Intel… but the layout of the chips shouldn't
have anything to do with the license. Conversely, if they were claiming it
was a Zappa and it wasn't officially licensed by Intel, there'd be a lawsuit
bigger than the OJ deal.
