Re: IBM 3174 C 6.4 Microcode Disks?
There was quite a bit of difference up until POWER6 although each generation came closer and closer together. It wasn’t just the IOPs, the systems had different management controllers, cases, expansion enclosures, etc as late as POWER5 and only ran AIX in LPARs or PASE. The early PowerPC 400s were PowerPC-AS chips designed in Rochester, MN whereas most other POWER and PowerPC work was an Austin, TX creation. Rochester did the RS64 family of processors which were very nice low power chips that also introduced “hyperthreading” and other advanced technologies but these were offered in RS/6000s as well for commercial workloads (DB, web services). https://en.wikipedia.org/wiki/IBM_RS64 On Fri, Feb 15, 2019 at 7:02 PM Paul Berger via cctalk < cctalk@classiccmp.org> wrote: > > On 2019-02-15 4:04 p.m., Liam Proven via cctalk wrote: > > On Fri, 15 Feb 2019 at 19:27, Paul Berger via cctalk > > wrote: > > > >> Knowledge Center refers to it as IBM i, but it is not the name of a > >> system it is just the name of another OS that runs on IBM Power systems > >> and can even be vitalized on a system with other OSes. > > IBM moved the AS/400 onto POWER processors.

IBM moved the AS/400 onto POWER processors. The TIMI (sp?) firmware made this doable and binaries were portable from the old hardware. The OS was renamed i5/OS. Later they replaced the proprietary POWER hardware with generic POWER servers, and they renamed the OS to IBM i. IBM supports 3 OSes on POWER servers now: AIX, Linux and IBM i. Silly name, though. Only the very first RISC based AS/400s where really different hardware, by the turn of the century when the second generation of RS64 / Power3 systems where coming along there was already a lot of common hardware between AS/400or iSeries and RS/6000 or pSeries only by Power5 time the hardware was all the same except iSeries was still clinging to the IOP but even that went away with Power 6 and even the support for Twinax WSC is gone now since the last ones where PCI.

The first time I heard it, I was convinced that the works were splattered all over the inside of the HDA casing and the machine was only continuing to run because of what was left in the disk cache or something like that. I started running a backup in case I might be able to salvage some part of the contents. Despite several more heartstopping clunks and clatters while the backup was running, it ran to completion, with no errors logged to my complete surprise. I ran an ANALYZE /DISK /READ which attempts to read all blocks on the disk that are allocated to files. Again, several more awful clanks and clatters but it completed with no errors. I lined up a replacement disk for it but I was curious to see how exactly it was going to fail so I decided to keep on using it for a while to see what happens. Days turned into weeks, weeks into months and months into years. It continued to occasionally make the same ghastly noises that never should be heard coming from a hard disk but with absolutely no sign of any errors being logged or damage to data whatsoever. The noises seem to be associated with seek activity because I have never heard them when the disk is just spinning but otherwise idle. I eventually retired it and replaced it with a much larger one, purely because I ran out of space on it. Any thoughts on what might be happening with it? Regards, Peter Coghlan.

I told him I didn't hold out much hope for success because I didn't have the vaguest idea how his little machine worked at that time but I agreed to wave my multimeter in the general direction of it's power supply. I opened it up and quickly found that the voltages seemed very reasonable and I prodded around the board rather aimlessly looking for some part that looked guilty. I soon noticed that one of the eight identical chips in a row at the bottom of the board was getting hot enough to burn my finger while the others remained cool and calm.

No luck with direct email (to either spacewar or brouhaha) or LinkedIn PM. I've been cleaning out my old garage and in the process, discovered some sheet metal (a pair of back doors for a double-wide cab, and one of the four white separator shims that goes between the three cabs) which belonged to the KL10 system that I donated to RCS/RI eons ago (and which they apparently sold rather than keep). Even though it's just cosmetic, and minor at that, I'd love to reunite this stuff with the rest of the system, wherever it wound up.

Just like approximately everyone else.

That reminds me of an amusing story from the first time I went to see 'Star Wars; I went with a group of people from Tech Sq. It has that scene where they're about to make the jump to hyperspace in the 'Falcon', and it won't go; so one of them (I think Solo) jumps up and whacks a particular spot on the bulkhead with his fist, and away she goes. We all found this terribly amusing, since one of the DEC time-sharing systems on the 9th floor had a sticky relay in the power controller, and when you'd try to power it on or off from the front panel, the relay would stick, and nothing would happen. So the procedure was to go around the back, open a particular door, reach in, and whack the power controller behind it in a particular spot with the side of your fist, and away it went! Noel

Got a nose for a hardware fault, eh? ;-) And some of my younger colleagues thought it was strange that I could predict hard disk failures from the running noises they made, and later than that, whether WinNT's bus-mastering DMA-mode disk controller device driver was installed from the sound of the disk accesses while the machine booted. BTW, Jeff, Gmail bottom-quotes just fine. I'm using the web interface right now. Just hit Ctrl-A, trim as needed and move the cursor. Yes, it's a pain on mobile, so I try not to answer on mobiles! -- Liam Proven - Profile: https://about.me/liamproven Email: lpro...@cix.co.uk - Google Mail/Hangouts/Plus: lpro...@gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053
RE: IBM 3174 C 6.4 Microcode Disks?
1) If it has a token ring card then it does not matter that it also has Bus+Tag channel card. It will still talk TCP/IP and other machines. 2) https://www.argecy.com/2389 have microcode. Al says he got some from them recently. I can copy the latest version but I am short of 2.4MB disks (and in th uk) 3) Boot up the diagnostics and utility disk. It will show the memory. There is a list of card numbers in the Maintenance Manual http://bitsavers.org/pdf/ibm/3174/SY27-2572-4_3174_1L_1R_2R_3R_11L_11R_12R_1 3R_Maintenance_May89.pdf 4) You need 2 x 2.4 or 1 x 2.4 and a hard disk for config C6. The smaller 3174's have a movable link for the PSU. No idea about the model 11 Dave (also some info on old Lordsnet site via archive.org http://web.archive.org/web/20080820002806/http://www.lordsnet.com/UsedIBM317 4Summ.htm Dave > -Original Message- > From: cctalk On Behalf Of Kevin Monceaux > via cctalk > Sent: 15 February 2019 03:29 > To: General Discussion: On-Topic and Off-Topic Posts > > Subject: IBM 3174 C 6.4 Microcode Disks? > > Classic Computer Fans, > > I posted this to the IBM-Legacy-Hercules mailing list.

Hi Randy, Here’s how to do it in Windows 10 (and probably 8): https://www.laptopmag.com/articles/set-time-limits-windows-10 For Windows 7: https://www.tech-recipes.com/rx/6900/windows-7-how-to-set-time-limits-for-a-child/ All the Best, Jim On Fri, Feb 15, 2019 at 00:17 Randy Dawson via cctalk wrote: > Before I develop this, I thought it may already exist, and the classiccmp > mail list might be the place to ask. > > What we have, is the screen time problem with the kids.
