If bankers minded playing second fiddle to technologists  these last few days at the Retail Delivery '96 conference, they didn't show   it.   
Many reacted enthusiastically to an Intel Corp. demonstration Thursday  showing how bank customers could video-conference with tellers over the   Internet.   
  
Others were taken with the showing Wednesday of Sun Microsystems Inc.'s  "thin" and cheap JavaStation network computer, and with Sun chief executive   officer Scott McNealy's lighthearted razzing of rival Microsoft Corp.   
Mr. McNealy and Intel executive vice president Frank Gill had keynote-  type slots at the gathering. The prominence given speakers from technology   companies is part of what sets the Bank Administration Institute meeting   apart from others in the banking business. That and the record crowd   estimated at more than 7,000.       
  
For the video-conference connection at the Dallas Convention Center  Arena, an official of U.S. Bancorp stood beside Mr. Gill and used a   computer to connect to a teller in Portland, Ore.   
Smiling from the monitor as Mr. Gill requested an address change, the  teller transmitted the new information to Mr. Gill's screen for   confirmation. Noting that he had a certificate of deposit that would soon   mature, she also asked him if he wanted to upgrade to a CD with a higher   interest rate.       
Community bankers, who place a premium on personal contact, were  impressed by the Intel system, called ProShare. 
  
"You can continue with the personal approach to banking without being  face-to-face," said Robert Critchfield, senior vice president of Citizens   Bank in Flint, Mich. "I wish I could turn it on at our bank today."   
"You can really let your mind wander" about the possibilities of the  technology, said John T. Franey of Firstar Corp., Milwaukee. "No one will   question whether we utilize this technology. It is only a question of   when."     
Noting many community banks have been slow to move onto the Internet out  of fear of damaging their ability to personalize, San Antonio banking   consultant Brent M. Ratan said, "Things like this really blow the community   banker's mind. It helps them to keep their advantage."     
During his presentation, Mr. Gill noted that microprocessors are  expected to double in power every 18 months, with corresponding declines in   cost. This soon will let consumers experience three-dimensional product   simulations and full-motion video via PC, he said.     
  
Mr. McNealy seemed unimpressed with the talk of computer horsepower. He  evangelized relentlessly on behalf of the network computer, a diskless   version of the desktop PC that relies on computer networks, such as the   Internet, for computing power and access to data bases.     
Mr. McNealy kicked off his presentation with a professionally produced  takeoff on Apple Computer's "1984" television commercial. In it,   brainwashed Microserfs are controlled by a large-screen display of Big   Brother Bill (read Gates, chairman of Microsoft), who exhorts his subjects   to"upgrade, upgrade, upgrade."       
He advised bankers to stop buying mainframe computers and to reject  Microsoft-style software upgrades. By using network computers that are   linked to a central computer server, Sun believes banks can dramatically   cut computing and maintenance costs. Sun derives the bulk of its revenues   from the sale of servers.
