Getting an ibm as/400

by jnc＠mercury.lcs.mit.edu

> From: Dave Wade > just as a program in virtual memory can be spread across any location > of physical memory, a "file" on an AS/400 can be spread across any > number of disk sectors on any drive Yes, but the same thing is basically true of most conventional file systems, e.g. various Unix/Linux file systems (although on most of those, files aren't spread across multiple drives, but there have been file systems that did that). > The original AS/400 OS had "single level storage" so basically the > disks were an extension to ram, or more that RAM is just a temporary > disk buffer. But that description is, in some sense, just what classic virtual memory (paging) does. The crucial difference is in what the _user sees_: in a normal virtual memory system, a process' address space is a simple one-dimensional array of bytes/words. In a single-level-store (sometimes called 'segmentation'), a process' address space is two dimensional: segment along one axis, address within segment along the other: https://en.wikipedia.org/wiki/Single-level_store Of course, one can have segmentation (in the sense of 'what the process sees') _without_ virtual memory (either paging, or swapping entire segments), but most systems that implemented segmentation also did virtual memory too; Multics, and the family of IBM systems of which the AS/400 is a later member, both did.

R: Re: Getting an ibm as/400

by supervinx＠libero.it

Yes. I had an AS/400 disk with too many grown defects. I imaged it with sg_utils and transferred the content back to an identical disk. It booted flawlessly...

Getting an ibm as/400

by tmfdmike＠gmail.com

I agree little point in imaging. First step: password guess; try logging in to account QSECOFR password QSECOFR; you may luck out and find it is the default. If that fails do a DST IPL (Google it) and use the DST QSECOFR account (NOT the same as the system QSECOFR account!) to reset the system QSECOFR password. You may luck out and find that even if they've changed the system QSECOFR password from the default, the DST QSECOFR still works. If that fails you're down to a partial reinstall - 'slipping the LIC' as Benjamin described. There IS a way of breaking into a System/36 by patching specific sectors and offsets on the disk; I have it written down somewhere. But I know of no analogous procedure for AS/400.

Reinstall (DO NOT select the option to install and initialize). This is generally referred to as "slipping the LIC". You can re-install it without trashing the OS. That'll get you into DST, where you can reset the password. What version of the OS does is currently installed? -Ben

H960 leveling feet

by jnc＠mercury.lcs.mit.edu

So there was a post awhile back that discussed replacement "leveling feet" for the stabilizing outrigger front feet on H960 cabinets (DEC's formal name for them is apparently "extension feet"); somone pointed out that one can buy such things, and gave some pointers. So I needed some, and here's the scoop: the threaded shaft on the leveling foot is 5/16"-18, and a suitable replacment part is Vlier FSE302S, available >from in the US from MSC Industrial Supply: http://www.mscdirect.com/ (US$1.84 each + shipping). I have obtained some, and they fit OK, with two caveats: i) the round foot part is a significantly larger diameter than the DEC originals, but they do fit OK on neighbouring extension feet (i.e. on a pair of H960's, both with extension feet); and ii) the threaded part is somewhat longer than the originals, so even when wound fully up, there isn't a lot of room between the foot and the floor. (Of course one could trim the threaded shaft, but I'm lazy.. :-) Anyway, if anyone in Europe needs some, and can't find any over there, let me know, and I can obtain some and send them along. I also need some of the larger main leveling feet, but I haven't been able (yet) to find any. The threaded part is 7/16"-14, but nobody seems to make 7/16" these days? (Everyone who makes them now seems to go straight from 3/8" to 1/2".) Anyone know of a source for these, or a replacement? Thanks! Noel

A couple of afternoons in Austin, Tx

by barythrin＠gmail.com

Think most our hotspots have been mentioned. Last I've heard Goodwill (franchise* so rules vary by city/owners) has a mandate to all goodwill in town that they must send all computer equipment to the goodwill computerworks store which is the one mentioned (off the frontage of north 183 and just before Burnett). Unfortunate for the other stores but makes it a single stop to know if they have anything vintage. Prices seem to model ebay though :-( but once and a while something nice is there. Pinballz arcade (N. Austin)/Pinballz kingdom (buda) are functional arcades catering to pinball and early games nut also newer titles scattered around. Most are for sale but IMO at "not interested in selling" prices (2.5x? Going rates). Game over videogames is one of our better retro and vintage game stores. A few locations scattered around town but ?also a little high on prices. The staff though are usually pretty knowledgeable gamers and enthusiasts though depending on age and location. They also line their walls with part of the owners collection or boxes of consoles. The north lamar/anderson location has a small area as their "museum". This is also who started hosting an annual "classic game fest" in town. Gamefellas .. one of Austin's early on used and vintage game stores. They tend to have more boxed console games than other stores which you'll find loose carts. I cant ever get a good vibe on staff though. One store seems to have the good geeks then two others have a teen thats listening to an ipad and seems disinterested but maybe thats changed.? I don't know what the schedule is but on (some?) Saturdays there's a commodore meetup group that Bo Zimmerman hosts. Possibility to see what I advertise as one of the largest commodore collections in North America. There are also a few hacker spaces but I'm not that familiar nor a member so not sure about touring those.

Fwd: Apple Fans, a reminder two working Apple-1's at VCF east

by applecorey＠optonline.net

One NTI and one byte shop board. If you attend Friday's Apple-1 classes you may get to play on one and you will be able to compare them to the current Mimeo and Newton reproduction boards. For the weekend we will be rotating units and will post a schedule when demonstrations will occur. Happy 40th Birthday Apple!!! Cheers, Corey corey cohen u??o? ???o?
