Based on what can be seen, I doubt that the RJ45 is for Ethernet. jwsmobile <jws at jwsss.com> wrote: The 53C710 was a standard NCR/Symbios product, not something custom-developed for the HP 9000. It was used in a lot of systems, including PCs. The 53C710 was introduced in 1992, so the design of this card couldn't be any older than that. HP made custom SCSI adapters of various sorts for some of their machines that didn't natively support SCSI, for internal use only for manufacturing, test, and repair of their SCSI disk drives. However, I don't think this is one of them. That does seem somewhat likely. Development of new hardware as standard products for the HP 1000 systems (previously HP 21xx, still using 21xx part numbers) had nearly entirely stopped by the mid-1990s, but a big customer could certain have gotten HP to design a custom interface.

So did you get any type of storage device or media with the machine? If so, boot it up and see what drivers and such are there? J

On Thu, Feb 19, 2015 at 5:59 AM, Johannes Thelen That is CS/80, not C580. You would need to find an 12821A HP-IB Interface to use that. http://www.hpmuseum.net/display_item.php?hw=486 If you did find one of those then you could use the HPDrive software on a PC with a GPIB interface to emulate a CS/80 drive. http://www.hp9845.net/9845/projects/hpdrive/

Mystery have solved! I traced down receive & transmit pins from RJ45 and scoped little bit. I found one pin bursting 9600baud data couple seconds intervals and I connected this to terminal.

I probably make some own high speed downloader boot ROM / hardware / PC soft just for fun, but I have to test those too. This is topic of its own, but do anyone know any 21MX assembler and microassembler for DOS/Windows? Or have I make one..? I have little (demoscene) project going on for this 21MX. Same project includes IBM 1800, hopefully... Later more this totally insane project, but I guarantee no old computer is harmed on that performance ;D Thank you all! - Johannes ThelenFinland Before microcomputers blog (Finnish) http://ennenmikrotietokoneita.blogspot.fi/

For years Grumman made it its business to buy up older computer lines that had some small amount of life in them and support them for as long as it could extract support contract payment out of the users. Without doing any development work at all, with only very limited bug fixes (at least that?s my experience with Solbourne). The timeframe is about right. Warner

The AICS Research site seems to be owned by a tax prep firm now, and all of the links I found point to the dead spot. There is something called "Software Informer" which has a version 3.1, but I don't trust anything anymore not to load up a system with bloatware or malware, no matter who they are. Thanks to the HP museum for the OS download and manuals, by the way. Thanks Jim
