Agree. Now to find an actual non-SAMTEC gold-plated part … that is “well-priced”. Do you have any specific examples/references/PN?

There’s always pt-to-pt wire and a soldering iron! Tedious, but no worse than gold contacts and seems likely to be _better_ from the perspective of reliability. Wire cutters for “disassembly” :->. Sti

Backplanes are important. Good connectors aren’t cheap. But Samtec sure is expensive. And then it will require two connector-pairs per junction. I’m definitely experiencing sticker shock! Maybe someth

Anders: I’m very interested in your proposal to “scale down to 4 slots, but add a connector and create a layout for an add-on board with 4 more. That means that you could have 4, 8 or 12 slots or even

HP terms that memory-bus bridge a “frontplane” :->. Rather requires those slots to have exactly standard spacing. The jumpers would be an *improvement* on the original; not sure why HP didn’t include

My guess is that it’s not a technical limitation; it’s a matter of being able to support a market-useful configuration. The A600 doesn’t have on-board Serial I/O nor memory, correct? So a minimum “ser

Geez Ed. It’s trivial to determine that the correct path for these files is: http://www.bitsavers.org/pdf/hp/9000_300/

Best pages are the second-to-last image – all DEC Big(ish) Iron :->. How does that fit the story-line? Nice coffee-table book, but it’s not like we have visitors any more … nor a “coffee table”.

12597 interface wanted
It’s not impossible to get around the CTuL I/O bus interface design. For example, the 8T13 / SN75121 is an acceptable substitute bus driver with the inclusion of a suitable pulldown resistor to -2V. 0

Would anyone be interested if I created a PCB design for an OOBIO-connector for the HP-1000 and made it public?
Why not a small PCB for the edge-connector to a 40-pin IDC? 40-pin cables are a dime-a-dozen thanks to the IBM PC.
