It does not seem to like coming up in my 2/160 (VME) system, while my 2/160 processor comes right up. I was sent what is supposed to be the right eprom by a very nice person, but that did not change anything. Any tricks I should try before declaring the board dead, an if it is dead, where can I send something like like this to get it fixed, and what kind of money am I looking at to do that? Whew! lots of questions. Thanks in advance!

The machine has 1Meg of 64k DRAMS on the motherboard, and 4Meg of 256k DRAMS on the 'SCSI/expansion' board (for lack of a proper technical name ;-). Is there anyway to replace the 64k DRAMSs with 256k's inorder to increase the total memory to 8Meg? A similar operation has been performed on AT&T 7300's to increase the motherboard memory from 512k to 2Meg. Since this is all (obviously) dependent on the memory mapping scheme, could someone describe the memory layout for me? Thanks in advance, -bill rankin wtr@bromo.att.com ------------------------------ Date: Mon, 11 Mar 1991 15:09:10 -0600 (CST) From: "Anthony A.

You only need 100ns, actually. Slower ones might even work, but I've never seen a slower one. >or can I just purchase 1x9 80ns SIMMS Yep. We buy ours from Helios, with a lifetime warranty. We pay something like $50 a meg for them. Ya just can't beat it. For generality, though, it might be good to just go with the 80 ns ones for a few more bucks -- they'll be more reusable in the future. -- In MDDT no one can hear you scream ------------------------------ Date: Mon, 11 Mar 91 22:07:38 EST From: gcd@einstein.bgsu.edu (Comer Duncan) Subject: Suns-at-Home Digest V4 #9 To: Suns-at-Home@ecn.purdue.edu I am wondering what people who configure Suns-at-Home from SparcStations such as SLC or SS1 are considering as minimum needed disk attached with enough space to hold the OS AND have enough left to do 'useful work'? Is the option of using a floppy to transport files back and forth from home to work a really practical solution? I am thinking of purchasing a Sparc for home sometime with color and need to know what the prevailing attitude is on disk space. Also, what happens when something breaks? I assume most of you guys can not afford Sun's prices for hardware support--I surely would not be able to... At my university we can get a SLC for about $2500. Adding color and disks would at least double the above figure...
