Elite Features.
____________ _
The PC ELITE card extracts the ultimate IEEE-488
performance from your Personal Computer. Using 4 custom
programmed logic chips we have taken PC based IEEE cards to
the limit. PC ELITE is a half size card that fits any PC or AT
slot. ELITE has the complete Controller, Listener and Talker
ability. True flexibility with a choice of 3 DMA channels, 10
interrupt lines and 7 I/O addresses.
Elite is based on the highly popular NEC 7210 GPIB
Controller chip, with 4 supporting custom programmed logic
chips controlling DMA, Interrupt sharing and address decode.
DMA data transfer rates exceed 300K bytes per second. The
ELITE card is as rugged as your PC.
_________________
Interrupt Selection.
The interrupt hardware allows jumper selection of one of
ten PC interrupt request lines, IRQ2 to IRQ7, IRQ10 to IRQ12
and IRQ15. The PC ELITE interrupt logic allows interrupt
sharing with third party cards. 13 interrupt sources are software
selectable providing ultra-flexible interrupt driven data transfers.
Direct Memory Access Channels.
____________________________ _
The DMA hardware allows jumper selection of one of
three PC direct memory access channels for high speed data
transfers, DRQ1-3. The PC ELITE allows DMA interrupt sharing
with third party cards. DMA data transfer rate exceeds 300K
bytes per second.

Address Switches.
The DIP switches give the ELITE card the choice of 7 i/o
addresses 02E1H, 22E1H, 42E1H, 62E1H, 02B8H, 02C0H or
0300H. Elite is switchable between PC2 and PC2a compatibility.
Four ELITE cards provide access to 56 IEEE instruments.
