- Well I believe Digital is doing something with EISA.

- NT enthusiasm spurs details on Alpha PC's
- Digital Review 7/27/92
-
- The PC servers, claimed to be five times faster than those based on Intel's
- 50Mhz 80486 processor, will be configured with either Windows NT, Open VMS or
- OSF/1 and will support existing EISA bus peripherals.

- "The [Alpha] subsystem will go in the same box as the 450 ST. You could
- upgrade by swapping out the insides of the 450. It will use the same monitor,
- same EISA controllers and peripherals. But you're not going to throw away a
- 450 ST," said Jeffrey Schriesheim, group manager for Windows NT systems
- software at DEC.
- The system, based on the EV-4 version of the Alpha 21064 processor, will be
- priced between $6,000 and $7,000 with 256MB of main memory and five EISA slots,
- he said.
- NT will be the primary operating system, said Robert Supnik, DEC's vice
- president of advanced VAX/VMS systems engineering.

- "We will use the PCI-to-EISA bridge in future systems. It's just that it
- won't be available for a few months," Schriesheim said. "We're working with
- Intel on it. This time next year PCI will be the right solution."
