There are many resources to help you. Start with Robelle's "HP 3000 Page", then follow the links for consultants, service firms, books, web sites, tutorials, and papers.
All will continue to support the 3000, even as Hewlett-Packard scales back and eventually disappears. The 3000 community is full of smart people who are dedicated to the 3000. They are eager to hear from you and have a history of providing great service, often better service than you get on average from HP. The 3000 world has always had small, nimble firms that lead the way, pushing HP along and filling in when they faltered.
For example, here are two useful papers by Paul Edwards:
First thing you need to know is that MPE has Unix-like features integrated into it (via Posix), but most applications and software tools were written with the non-Posix features.
Basic MPE consists of a single shell (the command interpreter) and a file system that has only 3 levels (user, group, account) but has many file attributes including record size/type, max file size, extents and passwords (called lockwords). The 3rd party product MPEX is an alternate shell, as is sh.pub.sys (the Posix shell).
Start your MPE experiences with a cross reference from unix commands to MPE commands, and then continue with out login tutorial and the other tutorials.
As an HP 3000 customer that continues to get cost effective and reliable use of your equipment for many years into the future, you must be self-sufficient and plan for modern day disasters to ensure a stable and protected environment. ... Your HP 3000 system is probably the heart of your company's business operation. Some disasters, like disk drive failure, are minor, while others can destroy the computer center or entire corporate structures. The top ten types of disasters, which have caused the most damage in recent years, are power outage, storm damage, flood, hardware error/failure, bombing, hurricane, fire, software error, power surge/spike, and earthquake.Read the entire article.

Cypress Technology lists 9 refurbished HP 3000s for sale at prices ranging from $500 to $25,000 and gives the End-of-HP-support date for each.
And there are many others...
First, select your geographic area from the menu at the top right. Then select "Servers/Workstations" from the browse list at the right. Then select "3000" - this lists all the systems (but the A class seems to be missing?).
Select your HP 3000 model. We tried N-Class. Then select a Keyword, Category or Part Type. We tried Keyword = 'memory' and were shown a screen with 512MB, 1GB and 2GB ECC memory modules (p/n A3763A, A4923A,A5864A). Prices should be shown, but in this case there aren't. There is a button to order , selected parts, but we haven't tried it yet (anyone?).
Since tape drives are the most likely part to fail, we tried finding them. Not listed in keywords, so we tried Category = 'Drives and trays'. Nothing. So we tried Part Type = 'mechanical', then 'electro-mechanical'. Then Keyword = 'drive' and Category = 'Electronic Accessories'. (No tape drives, but we did find some more memory parts, with prices this time).
We could not find a DAT drive for the N-class anywhere, so we tried a 989 system and found DAT drives under Keyword = 'drive'. Oh well, perhaps the N class systems don't use backup drives.
When we asked the author of Ramusage, the legendary Stan Sieler, how to calculate the amount of memory to buy, he provided the following formula:
In other words, buy as much as you can afford!
Now where do you buy more memory?
Well, you can get it from HP if you know the part number... and you can find the right page on their web site.
Kingston listed the 64Mb for our 928LX at $286, whereas HP was charging $1,090 (all prices are in US dollars). See the Kingston Web site at
Select 'Hewlett-Packard' from the pull-down list, then select your HP 3000 model number from the page that is displayed. At the time this book went to press in 2003, 512MB for a 9x9 was $665, and Kingston tells you the maximum 9x9 memory (3.2 Gb), how many sockets there are (32 in 16 banks of 2), and shows how the banks are arranged.
Another source might be third-party hardware maintainers like the ICS Group which had 128Mb for $600 (versus $572 for 128Mb at Kingston).
Finally, if you're really lucky (and brave), there's eBay.
The day that Paul looked for our memory, there were offers for 9x9 systems, so he contacted one of them (Sales@Hprecovery.com) and was quoted 128Mb of used memory for $95 (versus $572)! At that price it was worth the risk.
However you buy memory, it will probably take a small amount of research, because availability may be an issue. But it is also the cheapest and easiest way to boost your system performance.
"The main advice is that it's time to get out of the mindset that you always need to buy from HP and that if it comes from somewhere else it won't work. This is not the case. HP hardware is usually excellent and lasts way longer than most of our needs. The single exception here is probably their DDS/DAT drives."And since Paul also mentioned Allegro, I asked Stan Sieler of Allegro about used hardware and spare parts. Stan says:
"Once you've tried buying 3rd party, experienced the huge savings, and had a few good dealings, you're more likely to look around."
"At Robelle we tried alternate sources on a variety of items. We bought HP memory chips, HP JetDirect boxes and even small routers right off Ebay. We found great deals on non-hp 72Gig SCSI disc drives from Pricewatch:http://www.pricewatch.com/
"In this case we did have problems with the hardware, but the vendor replaced it within a week. We also got help from other HP regulars like Allegro in tracking down sources when we needed to assemble components." "So when your favorite big computer company stops supporting you, it's time to find out that others will support you."
"We have several HP 3000s and HP 9000s that were purchased either from eBay or surplus auctions. My comments fall into two categories: obtaining equipment and what to do once obtained.
- Obtaining equipment
- EBay (search for "hp 3000" and "hp3000" and "hp e3000").
Pay attention to seller's feedback rating, location, and method of payment before bidding. (I no longer bid if the seller won't take PayPal.)
Ask about condition, boards in the machine, etc.
Ask about shipping cost.
- Local surplus houses
- Once obtained
- Open system remove cards, vacuum, re-insert cards
- Erase the old disk drives using WipeDisk:
- Test memory, CPU, peripherals. (The online/offline diagnostics can be useful here, if you are able to run them.)
- Remember: 9x7 computers take significantly longer to boot up as you increase the amount of memory in them."
