DescriptionThis is a "first generation" RS/6000, in the typical IBM-grey desktop case. It has the original multi-chip power implementation, the typical backplane (IOPlanar in IBM-speak) with memory and cpu living on separate daughter-cards, a keyswitch and LED display.
MarketingThe IBM RS/6000* Model 350 is based on IBM's POWER Superscaler designed Architecture and is designed for balanced system performance providing a high-speed floating-point processor with concurrent instruction execution. The Model 350 offers a 41MHz processor, 32MB to 256MB memory, 160-MB to 4-GB internal disk, and four Micro Channel Feature Card slots. The Model 350 also offers flexibility with a wide variety of optional features and input/output devices to provide increased functionally, connectivity and price performance with the AIX* Version 3.2 for RS/6000.
The IBM RS/6000 Model 350 is a powerful multi-purpose, desktop system for commercial and scientific environments. A pedestal is provided for stabilization in the vertical position and is mounted on the bottom of the system unit when in the horizontal position.
StoryThis was a "classic" rescue. I got a phone call that (unnamed company) is cleaning up the warehouse and an old RS/6000 was at risk of being trashed. I was massively surprised to see that they had neatly set aside for me several RS/6000s, tons of memory still in its original packaging, various spare parts, and several sets of AIX installation tapes. Overwhelmed by the amount of stuff (I had calculated for only one machine and no extra parts, something I could easily tuck under my arm), I had to find a way to bring that stuff home (I have no car). So I called a taxi, and asked for one "with a big trunk". I couldn't take it all, so after deciding to leave the duplicates there, I ended up with this 7012-350, a 7012-340, a 7248-43P, and a few cardboard boxes with more than a hundred 64MB parity SIMMs, several memory carrier boards including memory, various MCA cards, and a dozen AIX tapes.

This machine

This machine has 64MB of RAM, two 16-port async serial cards, and is currently running AIX 3.2.5
All built-in connectors are labelled in a very complete, spelled-out form (it's even translated to German, as the machine was sold in Switzerland).
From left to right: serial 1, serial 2, ethernet (2-8), SCSI, 2x 16-port async serial (3-4), tablet, keyboard, mouse:
Old RS/6000 also have this stylish model badge (which unfortunately often gets lost):
The front panel has the keyswitch (with labels neatly translated to German as well), the reset button, and the LED display (on the right):
When opened, the machine apears very orderly, with the disk on an expansion-card like carrier, the MCA slots, and the pluggable (even upgradable) CPU and memory daughter-cards:
The CPU card featuring the original 6-chip POWER implementation. Yes this only one CPU:
The memory carrier:
The ethernet riser (there were different types of risers):
The harddrive carrier:
The inside of the machine with all cards removed:
