Article note: Neat.
I sort of distantly knew Unisys was still supporting the direct ancestors of Burroughs MCP from 1961 as ClearPath MCP - ported through a language change in the 70s and several architecture changes over they years - but you can literally run the direct descendant of MCP as a hosted environment on Windows on commodity x86_64 hardware _as a supported configuration_, and the latest release was just last year.
Article note: We really should be running manufacturing more-or-less on "Battlestar Galactica" protocols. There's no reason to plug that shit directly into an Internet-connected network.
... Or, to make another reference
You hooked it up to the ~~phone~~ Network, didn't you?
Dade! Turn the shower off! You screw up again and you ~~won't get into college~~ will break civilization!
Article note: Man, we're only like 10 years from "Never use your real name on the Internet" to threatening "The government mandates you supply your legal name to the ad-tech companies who have taken over the Internet"
Article note: Getting out of Sparc makes sense, no one gives a shit about commercial Unix anymore, Oracle has poisoned the waters around Sparc, and Fujitsu has seriously badass AArch64 designs that can take over in the remaining markets.
The mainframes though? That's an ...odd... move. There doesn't seem to be a ton of overlap between the "Mainframe customers" (serous mainframes, the GS21 family are basically modernized Amdhal ESA/390 compatible designs) and "Customers who will migrate to a new, small cloud provider."
Once Japanese giant's main squeezes, they're being ditched at end of decade
Fujitsu has confirmed the end of the road for its mainframes and Unix server systems. It will cease to sell both by the end of this decade, with support services continuing for a further five years.…
Article note: This is just weird. Yes, AMD has some compelling technologies in both the CPU and Graphics spaces, and recently acquired Xilinx, so they're well positioned.
Yes, Intel appears to be making some poor decisions. But they have a long history of terrible decisions that they've managed to get away with. More importantly, unlike AMD, they own an (expanding) ton of leading-edge fab capacity, and significant market dominance in almost every laptop-and-larger CPU category.
Article note: Very cool. The various RT patch-sets to Linux have always been under-maintained for how useful they are; there is a lot of industrial equipment out there that is really a RTLinux box, and it's generally not a bad solution.
An old friend of mine was moving cross-country and got in touch about taking “Some of his old computers” a while ago. I of course agreed, and it turned out to be quite a growth event for my hoard. There will be several posts about machines that arrived in this process as I get to them.
The list of things to be re-homed included “an Apollo” which I was hoping was a pre-acquision DN-something or a HP 300/400 series because I’ve had a long fascination with Domain/OS. What showed up is… not that. This is a later HP Apollo 9000/735 PA-RISC workstation, ca. 1992, which is easily the most exotic piece of hardware that transaction made me steward of. The OS options are HP-UX 7-10.20, a few BSDs, or a second-class NextStep 3.3 port; I’ll probably go with HP-UX10.2. It came with the requisite HP-HIL keyboard and mouse (thank goodness) and a DEC branded 5xBNC to VGA cable.
This thing was serious rarefied-air hardware when it was new: PA-7100 99 MHz processor, 208 MB of RAM in 12 obscene proprietary 16MB RAM modules + 16 soldered to the processor board, a HP CRX-24Z video board, a full-height SCSI HDD, and an AUI Ethernet daughter card. Probably in the ballpark of $60,000 new. It is also built like a piece of high-end industrial equipment, with big sheet-metal frames with handles that pull out of the back of the system for every major component.
My first attempt to power it resulted in …a feeble blink of the power light. That suggested to me that the PSU was bad, probably due to defunct electrolytic capacitors. So, in standard “old electronics troubleshooting” fashion, I pulled the PSU, tore it down, read labels off the most suspicious capacitors, and ordered replacements. The HP Museum folk also suggest the AC line filter module is a time bomb on all of these, so since it’s still made, I grabbed one of those too.
List with Mouser links, since they were the vendor with everything I needed in-stock: 8x 2200uF 25V, 12.5mmD 40mmH, 5mm lead spacing , Nichicon UPJ1E222MHD email@example.com 1x 220uF 35v, 10mmD, 20mmH, 7mm lead spacing, Nichicon UPM1V221MPD1TA 1@$0.72 1x 1x 22uF, 25V, 5mmD, 12mmH: Nichicon UPS1E220MDD1TA firstname.lastname@example.org 1x 12uF, 35v, 5mmD, 10mmH, Panasonic EEA-FC1V120B 1@$0.39 1x AC Power Entry Module, Schaffner FN9222R-10-06, 1@$6.50 I also ordered a couple 470uF 25V, 10mmD, 20mmH, 5mm lead spacing caps, but ended up not installing them because there was no sign of damage and they were hard to get a good angle on.
I passed on dealing with a couple smaller electrolytics with no signs of damage, and also two gigantic 2x 1200uF, 250v, 35mmD, 47mmH, 10mm lead spacing input caps that cost $7.50 a piece, since they looked both fine and like a fight to get out without damaging the PCB. One of these days I really need to invest in a proper pump-driven desoldering gun to make this kind of task safer and easier.
I of course picked up an extra 1-2 of each since it was noise over paying for shipping, and it’s a good thing because I dropped one of the new 220uF/35V parts and it instantly disappeared forever, presumably to wherever my cat has been hiding toys recently. The new input filter is slightly longer than the original and required a bit of creative terminal bending to fit around the caps, but it made it back into the case. After the recap, it powered right up, and on a second try after giving the hard disc a gentle thump to unstick the heads from park, everything spun right up.
It booted to status LEDs at that point, and shows “8,6,3,1” which according to the service manual indicates “Autoselection Failure to Find Boot Device” – probably meaning the HDD is dead and/or wiped. The appropriate HP/UX media is easy enough to find. Unfortunately, the monitor on my basement bench doesn’t seem to want to sync with the presumed 1280×1024@72Hz Sync-on-Green coming out of the video card, so I’m stuck for now until I can find a workaround. There is a 4th BNC labeled “Stereo” that might somehow be useful for sync? Or I need a scan converter/sync stripper gadget? … further research required.
If you have an apple and I have an apple and we exchange apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas.
