Centris 650 Ethernet

Carr" <ajcarr%ollamh.ucd.ie@Forsythe.Stanford.EDU> Subject: [*] Centris Ethernet Report Dear All, A week ago I sent out a request for information about the built-in ethernet connection in a Centris 650 (as in our College Microstore didn't want me to use it). I enclose the responses I received for filing as a report. The consensus is that the inbuilt connector is the thing to use, with the caveat that Apple's self-terminating transponders may cause problems. One respondent seems to have had very bad problems with Quadra 700s, cause unknown. Many thanks to all those who replied. Alun A. J. Carr, Mech. Eng.

The College Microstore from whom I purchased the above beast tell me that I shouldn't buy the Apple RJ45->thin co-ax adapter for this, but that I should buy an Asant\'e NuBus card instead. They tell me that this is because (i) Apple don't know anything about Ethernet connections (which I find a mite hard to believe) and (ii) NCSA/BYU Telnet 2.5 doesn't have a driver for these inbuilt connections (though I would have thought that there'd be a few Quadras at the NCSA, of all places!). Does anybody have any good/bad experiences of using these inbuilt connections? Would a NuBus card be any better (a colleague and myself have had bad experiences with Asant\'e products in the past---like his SE with an Asant\'e card in it refuses to talk to his serial DeskWriter C when networking is turned on)? Do I have to buy a copy of MacTCP 1.1.1 to use the inbuilt connection with NCSA/BYU Telnet? Should I have kept the Microstore happy and bought a 486 (urgh, yech, retch...)? Please respond direct, and if I get a suitable number of responses I'll produce a summary. Thanks, everybody.

Bremmer) Subject: Mac built-in ethernet To: ajcarr@ollamh.ucd.ie Hello, Here at Calvin College we received three Quadra 700's, and bought coax tranceivers for them. One worked perfectly, one had intermittant ethernet problems that seemed to become permanent, and the other would only allow you to use the ethernet if you had booted from a floppy with System 7.0.1 and the ethernet drivers on it. It refused to access the ethernet when it booted from the hard drive which was configured exactly the sam…
