Il 1 Il ' KINETics FAsTPATHI New PROMs for the FastPath APPLETALK INTERNET A hardware upgrade for the Kinetics FastPath (the PROM 3.0 upgrade) is now available. The new PROMs provide somewhat In past issues of our newsletter we have described the Apple better performance for the FastPath, and also make it easier to Talk Internet and discussed how to connect departmental configure the FastPath. We have some extra PROMs and can AppleTalk networks to the campus Ethernet using the Kinetics help you upgrade your FastPath if you do not yet have the FastPath. If you own or are considering purchasing a Kinetics version 3.0 PROMs. Those of you who ordered your FastPath FastPath AppleTalk/Ethernet gateway, you should know about after November, 1987 already have the new PROMs. some new developments. Improved FastPath Reliability Connecting a FastPath to the Campus Ethernet Some of you are using the FastPath in noisy environments. If you have a Kinetics FastPath AppleTalk/Ethernet gateway 'Noisy environment' means that there is occasional noise on that you are going to connect to the campus Ethernet (or the Ethernet segment to which you are connected. Some LAN mark), you must configure your Kinetics FastPath Kinetics FastPaths are susceptible to problems when they properly before you connect it to Ethernet Specifically, you encounter noise on Ethernet The symptoms are: need to choose AppleTalk network numbers that do not conflict with the network numbers that are already in use by other * an otherwise normally operating FastPath suddenly stops departments with Kinetics FastPaths. Choosing an AppleTalk network number that is the same as someone else's network * you are unable to fmd the FastPath with the FastPath number will produce strange results. manager program To avoid Apple Talk network number conflicts, the Microcom * if you turn the FastPath off and then on again, the FastPath puter and Workstation Systems Group is coordinating assign begins working ment of AppleTalk network numbers and zone names. Before This problem is caused by noise on Ethernet being coupled into you connect to the rest of the campus, contact Dave Burris or the serial interface adapter on the FastPath where the main Mark McCahill. The easiest way to contact them is to send system clock is generated. The extra noise on the clock causes them e-mail. Their e-mail addresses are: the processor to stop. Turning the FastPath off and on again [email protected] resets the processor. Then everything is fine until there is [email protected] another burst of noise on Ethernet. mpm@ACSSVX Kinetics has come up with a hardware modification to the Alternatively, you can call the Micro HelpLine. As well as FastPath that makes it much less susceptible to Ethernet noise giving you unique Apple Talk net numbers, we can make sure induced problems. (The FastPaths that are being delivered now that you are using the correct version of the Kinetics FastPath have been modified to correct the noise problem.) We have gateway code ....Which leads us to our second topic. tested the hardware modification and suspect that some of you will want to upgrade your FastPaths, since this will improve the New Kinetics Gateway Code and Ethernet reliability of the FastPath. The hardware modification involves Kinetics recently released a new version of their gateway code relocating a capacitor from the printed circuit board onto two of which supports Macintosh lis and SEs with Ethernet cards. the pins of the serial interface adapter. This involves some That is, this version of the gateway code allows a Mac II with close-tolerance soldering, so it is probably something you will an EtherTalk card to access all the resources on an Apple Talk not want to do yourselves. Instead, you can either have network. This code would enable you to print to a LaserWriter Kinetics perform the hardware modification or we can modify on AppleTalk via the Kinetics FastPath. The new version of your FastPath. the gateway code supersedes the 'combgw. s rec' code that a few of you are using. More important, the new gateway code If you want Kinetics to perform the modification, you should ('etalkgw. srec') does not coexist with old versions of the call Kinetics Tech Support at (415) 947-0998 and get a return gateway code; so everybody who is using the combgw. srec authorization so you can send your FastPath to Kinetics. version needs to upgrade.
