PDP-8 for free, ACT FAST!!!! Like, This afternoon

by mbg＠world.std.com

The following was posted on alt.sys.pdp8... I don't have any other knowledge of it, and can't save it myself... SOMEONE, please save it! I have been asked to post the following anonymous tip about the availability of a PDP-8 system in Boston: ------------------------------ Two functional PDP-8e minicomputers, 32k, RK8e disk, TD8e DECtape, bound for dumpster in Boston Friday afternoon, 18 december. Researcher has finally decided he needs floor space more than potential access to original data. Also RK05 disk packs, documentation, tapes, etc. In racks, with wheels. 243 Charles St., Boston, alley beside Mass. Gen'l Hosp. Founders' House, rolling out between 4pm and 6pm. "Too much paperwork" to donate or sell, they say. If you have a truck, and make appropriate offerings to the housekeeping folks, they could be yours. ------------------------------ That is today! If you're in Boston and want a PDP-8 or want to help someone get one, please act fast! Please pass this note on to anyone you feel could help rescue this system. Doug Jones jones(a)cs.uiowa.edu

I can certainly see the issue with making content appear to be yours, when in fact it was someone elses (I seem to remember someone framing WSJ articles this way, and rightfully getting busted.)

Halleluyah! Hooray! Eureka! Success! (OS-65U)

by bill＠chipware.com

A few of you may know that one of my first postings to Usenet (alt.folklore.computers) was a request for a copy of Ohio Scientific's OS-65U 6502 operating system. I have been looking for it since 1993. Well, Santa came to me a little early today in the form of the UPS man and I have here in my hand (well, sitting on the desk next to me) a factory original set of 8 inch floppies of OS-65U! Level 1 version 1.44 CD-23 revision. I also have demo disks, and level 1 v 1.2 CD-7 revision. I think to myself, "My quest is over." Now the real work begins. I own six 8 inch floppy drives that came with OSI machines. None of them have had a disk in them since I have owned them (I haven't had one to put in them until now!). three are: Siemens FDD 200-8P one is: Shugart Model 801 the other two are in a box, I'll have to check later. One of the Siemens has the gold face plate I mentioned in another post. The Siemens look like double sided drives, the Shugart is definitely a single sided drive. Nothing on the disks indicate single or double sided. I think they are soft sectored (only one index hole). How should I proceed? Could I get full repair and calibration instructions for these drives? Does anybody have an 8 inch set up that can read and duplicate most formats? Maybe recover questionable/compromised data on the disks? Thanks, Bill Sudbrink

SOL feeding frenzy?

by Watzman＠ibm.net

Actually, in the US, the FCC regulations on emissions did not go into effect until 1981 or 1982, before that the only laws were those general laws against operating an unlicensed or unauthorized transmitter. You could make an argument that any given item constituted such a transmitter, but even the FCC did not interpret things this way until the formal Class A / Class B certification rules went into effect. Kits are a "grey" area, but generally it would be expected that they would comply when assembled according to the instructions (and believe me, pre-1980 computers are generally WAY out of compliance). Since you are dealing with a "regulation" and not a "law" (in the US, anyway), enforcement is an administrative function of the FCC rather than a civil/criminal action by the courts (although in some cases it can spill over). The safety issue, in the US, is NOT a legal requirement (except in the state of Oregon and some cities/counties, including Los Angeles). Otherwise, there are generally no laws requiring UL approval. But just try to get insurance or defend a lawsuit if you are a company that markets a non-UL approved product. UL only applies to devices that use certain threshold levels of voltage; a board would not be impacted, but an IMSAI chassis that plugs into the wall, for example, would - and it would not pass (there is exposed full line voltage, among other things). ---------- From: Tony Duell [SMTP:ard@p850ug1.demon.co.uk] Sent: Wednesday, December 16, 1998 8:38 PM To: Discussion re-collecting of classic computers Subject: Re: SOL feeding frenzy? > > I would actually like to be able to buy a "new" IMSAI (for example), = > even if it wasn't made by IMSAI, but I would want it to be understood = > that it was a newly produced copy. It won't happen, however, in part = > because it would be illegal to make any of these computer as "new" = Well, there might be interlectual property/copyright problems, but do the other rules apply to kits/bare boards? The UK rules are strange IIRC. Kits have to pass the appropriate directives (covering EMC/safety, for example), when assembled as per the instructions. But I seem to remember that bare boards can be classed as components, and are thus exempt. Of course if you then populate the board, you'd better make sure it causes no interference. Or at least I think that's roughly how most people interpret the regulations. The people who composed them seem not to realise that experimental designs exist, that example circuits exist, and that nobody can know what a circuit will do until it's built and tested... > products. There were no FCC regulations when these machines were = I am sure there _were_ FCC rules, mainly to do with causing interference to other services. Now, if it causes no intereference outside your house, who is to know or care :-). OK, if %random-public buys a computer he should be able to assume it'll not interfere with his TV in the same room. But if you build one, then provided it only wipes out _your_ TV and not those of your neighbours, then there's no real problem. > originally built, and none of them are in compliance, and they couldn't = > be put in compliance without a complete redesign (in fact, they are WAY = > out of compliance). Most of these were also not UL approved either. So = I don't see how UL approval can be applied to a bare board (OK, if it's designed so user controls are live or something...), since whether it is safe or not depends on how it is constructed, what parts are used, whether or not it is cased, etc. -tony

2650 (was:Type list (was: single instance machines))

by CLASSICCMP＠trailing-edge.com

>> I seem to recall that there were commercially available 2650 S100 cards.... >Do you have more information ? I recall this as well. The source of more information would undoubtedly be to page through a big stack of _BYTE_'s from the mid and late 70's. Remember, in the S-100 world "commercially available" means that someone etched a PC board and maybe, if you're lucky, they actually typed up a manual with hand-drawn schematics. Tim.

Modem tones over television or radio

by jfoust＠threedee.com

Somewhat apropos the recent thread about sending mains power through modems, can anyone tell me if it's legal or illegal here in the States to send data in the audio of television or radio? Certainly there would be bandwidth and therefore speed limitations, but does the FCC allow this? Is it legal in other countries? - John
