Perhaps someone here has a better idea of what might be going on. I recently bought a sun 3/160 for home use. I am attempting to add a Fujitsu M2263E 778MB ESDI drive as ESDI device #1. I am having alot of difficulty with it. First, I have upgraded both the MD21 board to the highest rev level I could get from Sun, then upgraded the ROM to A98E (from the original G02A). This is likely *not* the highest rev board available. Emulex claims the A98E is necessary for the equivalent Maxtor to work. When I attempt to format it using the geometry Fujitsu supplied, the controller rejects the attempt and uses its own defaults. The format succeeds, but during surface analysis, at a random point on the disk, a soft error is reported. Attempting to repairt the soft error results in a "I can't find it" error. After the first error, soft errors continue across the surface of the disk in a semi-regular manner. Attempting to actually use the disk under Unix results in many many soft errors. I am using geometry of pcyl = 1658, ncyl=1656, acyl=2, nsect=51 with the drive strapped for 53 sectors (ie 2 slip sectors). Anyone have a clue as to what is happening? Does the MD21 need to be upgraded further?

Squires" Subject: Local Sun User Group forming in central Indiana To: suns-at-home@orchestra.ecn.purdue.edu An organizational meeting will be held at IUPUI on April 17 at 5:30 P.M. of people interested in forming a central Indiana Sun User Group. A speaker will be provided by Sun who will discuss system administration, including (possibly) differences between 4.1.1A and 4.1.1B. mikes@iuvax.cs.indiana.edu 546 N Park Ridge Rd., Bloomington, IN 47408 Office: 812 855 3974 Home: 812 333 6564 ------------------------------ Date: Mon, 25 Mar 91 19:56:06 EST From: lokkur!scs (Steve Simmons) Subject: Memory upgrade for Sun 3/50 To: Suns-at-Home@ecn.purdue.edu Chris Clack writes >I want to upgrade my Sun 3/50.

There are a number, with largely similar prices. When these first came out some were better than others, but now they all seem to be equally reliable. The first type is a straight 0-4-8MB ram expansion board. These come from various vendors, but all work on the same principle. You buy an expansion board. To install it, you remove the 68020 and assorted other chips from the motherboard. Into the empty sockets you insert the expansion board. Then you insert the chips into the expansion board. Put the board back in the machine, and there you are, more ram. These boards come with room for up to 8 1MB SIMMs. I don't know the exact speed, but my vendor offered to sell me more (I have 4MB) for $50/MB. Ram must be inserted in 4MB increments. No board I know of will take 4MB SIMMs. One board is slightly different. It will allow up to 12 SIMMs, and uses a different power/refresh cycle so as not to overload the power supply/motherboard. This board was about 20% more. Where to buy? I bought mine from Australasian Memory, now called Castle Rock, strictly based on price. They sell a 4MB board for $585.00, $8MB for $855.00. I priced 0MB boards, but none were cost-effective. Australasian/Castle Rock is at 408-883-1642. Delivery was 3 days from phone call to arrival. I have no relationship with them except as satisfied customer. ------------------------------ Date: Mon, 25 Mar 91 12:56:36 PST From: nhess@us.oracle.com (Nate Hess) Subject: options for connecting Sparcs via leased line To: suns-at-home@orchestra.ecn.purdue.edu I am interested in gleaning as much information as possible regarding what hardware and software to use to connect two Sparcs over a 56Kb leased line. Any comments, restrictions and/or suggestions would be most appreciated, especially in the hardware realm. (I'm hoping to use PPP.)

Squires" Subject: Tape Drives To: Suns-at-Home@ecn.purdue.edu There are now some sources for Archive 2060S and 2150S SCSI 1/4" tape drives at prices that are not too outrageous. I paid $500 for a new 2150S and have seen used ones with warranties advertised at $300-400. This kind of thing is found in "Computer Hot Line", a trade pub containing ads by resellers/ repair depots/surplus houses. I personally find that 350MB is the minimum size I will tolerate in a stand-alone system; this is not yet cheaply obtainable with 3 1/2" drives but there are 350MB and 450MB 1/2 height 5 1/4" SCSI drives from Micropolis and Seagate on the market now. The old CDC 330MB used by Sun is now readily available surplus; the Wren VII 1GB drive is now easily obtained, new, for $2500 and is available in quantity for less than that. ------------------------------ End of Suns-at-Home Digest ******************************
