One part of Hewlett-Packard's end-game fantasy about the 3000 pointed to parts. This was a server the vendor wouldn't build after 2003, HP warned. You could not be sure your server and its essentials could be serviced -- where would the parts come from? For the last decade and more, HP's 3000 parts have come from everywhere. About the only hardware services supplier constricted by the halt in HP manufacturing of parts was -- wait for it -- HP.
While practicing the careful shrink-wrapping of HP-built replacement motherboards, disks, IO buses and power supplies, the market has shared and sold ample hardware to replace 3000 systems. One reseller reported on the 3000-L he has hundreds of HP 3000 terminals on hand and was ready to send them to the scrapper. There might be sites where HP's tubes are essential for production operations, but I hope not. The scrap heap looks like the next stop for those 700/92s.
On the other hand, there are a few consumable items that make HP's hardware hum. One is essential to smooth operation of a service processor. You can get a replacement part for this processor at your grocery store.
(I still have an HP 14B calculator here, given to me as a 1989 HP 50th anniversary memento, which fires up each time I press the On key. I used to think it was solar-powered. How could any batteries last 27 years? Ah, the HP of old. Perhaps those batteries came by way of a NASA supplier.)
And the GSP's battery? Lalley says it's a CR2032, a part HP installed in a commercial server that once sold for tens of thousands of dollars. Or to put it another way, without ever owning an HP 3000, I've got a replacement part for an essential 3000 subassembly sitting right here in my hutch. Right next to that 14B with its 1989 batteries.
There are good reasons why HP's hardware for MPE/iX may not be a wise very-long-term component for production computing. But a lack of parts never was a good reason back in 2002 -- and it's just a tall tale today, even if the parts are aged like fine wine.
