By which I mean, it stops echoing the keyboard and stops tracking the mouse. It's driving me nuts! I've tried killing almost every system process except the bare minimum, to no avail. No message is printed on the console, but all I can imagine is that it's periodically trying to check ie0 (which is of course not responding as I have no transceiver or network). This happens in both Sunview and X-windows. If anyone's dealt with this, I'd *love* to hear from you! chris ------------------------------ Date: Mon, 3 Apr 89 13:18:07 PDT From: pur-ee!uunet.uu.net!zardoz!neil (Neil Gorsuch) Subject: Suns-at-Home Digest V1 #5 To: uunet!caen.engin.umich.edu!dmuntz@uunet.uu.net > 3) Daisy-chain a SCSI disk in with the Adaptec controller. > (I'd just as soon not do this for financial reasons, but I'd > like to know if it has been tried.) I don't know if this is cheap enough, but you can add a 300 Mb scsi disk into your box for $1900. I am also sending our latest price list in case you are interested. There are smaller, cheaper scsi disks, by they are not on the price list. Give me a call at (800) 433-6784 and I can look them up for you.

(I'm not sure if there's space > or compatibility for this option) I ran a 2/120 at work with an external box that contained two additional adaptecs (internal to the 120 was an adaptec with dual 86 Mb drives), the first external adaptec was adress strapped to 1 and had a 140 Mb and an 86 Mb and the second one was address strapped to 2 with a single 86 Mb. I would have had dual drives on the second controller except I ran out of power and space (I was using a pc case with a 200 watt power supply). A couple of things to watch out for and look for: 1) the daisy cahin can be done from the shunt connector on your sysgen board, if you have one. Otherwise you will need to create a cable that has a 50 pin socket and a 50 pin connector on the end. Plug the existing cable into the socket and the plug back into the internal adaptec and route the remainder of the cable outside. 2) Make sure that only one adaptec is terminated (little flat blue or yellow things in front of the scsi header on the adaptec). Too many terminators is worse than none. 3) Make sure you do not flip the cable over (pin 1 to pin 50) when you extend it. Almost immeadiately after you apply power your cable will melt down. If you are lucky, that is all the will burn. > 3) Daisy-chain a SCSI disk in with the Adaptec controller. > (I'd just as soon not do this for financial reasons, but I'd > like to know if it has been tried.) Believe it or not, at one point, the above system also had a 170Mb drive attatched to it as well (instead of the second adaptec and drive). Worked great. I have a 100U (almost the same as a 2/120) that I am working on attaching a 380Mb drive to. All I have to do is come up with the money to pay the man with. I expect no problems. > 4) Throw away one 50meg drive and replace it with something bigger. > (anyone want a used drive :-) Want to throw it my way? I like extra disks! > [I've taken this approach.

Apex in Seattle occasionally has 4 meg boards in and the last time I checked, they were running around $1000-1200 depending on demand. In thumbing through the Sun FE handbook, it is interesting to note that they recommend only two memory boards in a multi-bus system. One on either side of the processor. From past experience, I have found this to be true. You can run up to four boards in a 120 but it generally takes just the right four boards. I just about drove our service technicians nuts swapping boards until I had all 8 of our 120 type machines where they only parity errored about once a month ;-). This was running four 1Mb boards. The best I could do with the 4Mb LCF boards was 5Mb (1-4Mb and 1-1Mb), again two boards. When I added another 1Mb, The machine would drop about once a day depending upon usage, with a parity error. I was never able to get them to split for a 3Mb board so I could try the full 7Mbs with only two boards. =========================================================================== Mark Holm ..tektronix!ogcvax!cvedc!exc!markh Exceptions ..tektronix!tessi!exc!markh 126 NE Grant Phone (503)648-8307 Hillsboro, Oregon 97124 Messages only until after 6:00 PM One cannot accomplish the impossible, without first attempting the absurd! ------------------------------ End of Suns-at-Home Digest ******************************
