here's a weird old wearable computer that i found at work. pc-104 boards in a case that's apparently shaped to sit against your hip: it has these funky little adapters that plug into camcorder batteries for power, you can see i have it plugged into two in this picture. i got one running what i think was openbsd:  old picture of a microvax running netbsd:  alphastation running vms:  adm-3a terminal connected to my pc and playing some sort of mud iirc:

What connector? edit: my Octane has PS/2 ports and I already have two SGI keyboards with PS/2 connectors, so give it ti someone else.

eschaton posted:it can always be adapted into a USB device I thought those adapters just mapped pins and the device still had to know how to speak both PS/2 and USB. edit: either way, I've already got two SGI-branded PS/2 keyboards for my Octane so I'm set. Give 'em to the other guy that was asking.

I'm not talking about the adapters that came with mice in 2001 I'm talking about an Arduino with a USB HID stack (like a Leonardo) with its GPIO wired to the keyboard's weird bespoke connector and some software implementing the keyboard's weird bespoke protocol so it can be used with a modern system, people have put these together for all sorts of workstation keyboards and other devices and it's honestly petty awesome I've been trying to make one for HP Human Interface Link (used on HP 9000/300-400 and early 700 systems) for a couple months so I can twiddle some sweet rear end HP knobs, I've had issues trying to bitbang its weird 12/odd/1 serial protocol since I can't just have a UART do all the work

HP did make an adapter (A4220-62001) according to Wikipedia, but I assume you know that. Have you considered buying something with an HIL host interface and tearing out whatever IC does that and using it instead

my two SCSI2SD adapters arrived a couple days ago and I tried to set one up today I managed to brick one by attempting to update the bootloader, might be able to use JTAG to reload it though the other one I didn't touch the bootloader, just the firmware, and put it in a Sun 411 case that I picked up. it appeared to work fine under NetBSD but kept getting parity errors when I tried to install either OPENSTEP 4.2 or Solaris 2.5.1 on it I may need to get another spinning disk just to test whether it's the case, the cable, or the SCSI2SD board itself I was really hoping to take advantage of the ability to emulate multiple targets since that's the easier way to run multiple operating systems

Dug up some better pics of MY OCTANE. I think I took these before I had hooked it up or some damned thing. System module is on the left. Graphics hardware is on the right. Between the big system fan on top and the power supply on the bottom is an empty spot for a PCI card cage.  System module. MIPS R12000 CPU is under the big heatsink on the left  SE graphics hardware. No texture memory

eschaton posted:certainly you can max it out for cheap these days Looks like a few hundred dollars and good timing on eBay. I'd be tempted if the Octane wasn't in storage in another state. I'm going back to AZ soon, hopefully I'll be able to pick it up and bring it home. Hopefully the NVRAM battery isn't dead. What a brilliant idea to store hardware information required for licensing etc. in battery-backed RAM instead of an EEPROM or flash. Will SGI machines even boot if the NVRAM is dead? Never mind that the battery is actually buried inside the NVRAM so it's non-replaceable.  atomicthumbs posted:make sure you don't touch the completely loving idiotic contact pads for the gold-plated bristle connectors Definitely.

Never mind that the battery is actually buried inside the NVRAM so it's non-replaceable.  that its lovely for people that have them now, but SGI probably liked it. they probably wouldn't let that be a problem for people with support contracts, but they don't gain anything by us playing with these machines today.

I would think it'd make more sense for them to at least use replaceable batteries if for no other reason that to make their own support costs lower. Instead of having to replace the system module for a customer if the battery died, they could just replace the battery. It's frustrating because the IC SGI used for the NVRAM/RTC in Octanes has a variant that's identical except it takes an external battery.
