HP logic analyzer QFP132 interposer and DSD-4140 microcode ROMs

by jzatar2＠illinois.edu

Hello everyone, I've got two unrelated things I'm looking for: The first is an HP logic analyzer interposer for the emulation adapter for an MC68332. This would have a PGA socket on it, and sort of a reverse socket for the QFP132 package (attaches to a chip from the top, to interface to a chip soldered onto a board). I believe the part number would be HP E3417A. I already have the QFP160 adapter, but the chip I want to interface to is a QFP132. This adapter supposedly exists, but I've had no luck trying to find it through the usual channels. The second that I'm looking for, is if there's someone out there that owns and can dump the microcode ROMs from a DSD-4140 QBUS floppy controller. We've got a card here that's missing one of the ROMs, and we're also not sure if the ROMs are mixed up, so a dump of all 4 ROMs would be appreciated. They are 82S181, but they should read in any EPROM burner with a breadboard and some wiring to adapt the pinout. Burning them is another story, but we'll worry about that later... Here's a picture of the card in question: https://i.imgur.com/tzYjPYF.jpg And if anyone has one of these and is kind enough to dump it for us, there's also an 82S137 on the card that probably deserves a dump as well. Thanks, Joe Zatarski

UK: FF : 2 x Sun Enterprise M4000

by silvercreekvalley＠yahoo.com

Hi all I have a couple of near identical Sun Enterprise M4000 servers fitted with SPARC64 VI 2.1GHz CPUs, 16GB and I think 2 x 146GB disks. I *think* these are working but have never powered them up. I purchased them surplus a year or so ago. Available free of charge to any Sun fans - these are collection only sorry. I?m not too far from Cambridge location wise in the UK. PM me if interested. First come first served. Thanks Ian
