I think >the product name was SupRMod or SupRMod ][ or something like that.... If you want to be Captain-Nitpickily accurate, it was called Sup'r Mod, and the supplier's name was Marty Spergel -- the guy who first made himself famous at the Homebrew Computer Club by GIVING away an Intel 8080 chip. ("*gee!*") It wasn't that "Apple could not get FCC certification for an RF adapter," but that they knew darn well they didn't want to, because it would have slowed things up, cost a lot, and maybe forced design changes. Independent certification for a third-party RF modulator was much easier and cheaper. So the ]['s went out with advice to the customer that they did NOT meet FCC spec, and that if interference was encountered, it was the customer's responsibility to interpolate a proper device. I suspect Apple actually subsidized the certification of the Sup'r Mod, and everything after that was gravy -- Apple got off the FCC hook, the ][ stayed cheap to build, and Marty sold a g'zillion Sup'r Mods and got modulatedly rich. __________________________________________ Kip Crosby engine(a)chac.org http://www.chac.org/index.html Computer History Association of California

Beginners Need Help

by photze＠batelco.com.bh

Hello. I'm not so much a classic specialist as a computer specialist, as I love both old and new computers. I'm not a proffesional, but do know BASIC, DOS and all other kinds of stuff which the fast-moving stream of technology has left behind, unfortunately. But anyway, I didn't know jack about computers in the early 80's, other than what the average Joe knew: Keyboard, commands, annoying. But since '92, I've been learning more and more. But I need a basic list of systems that are 1. Easy To Find 2. Important enough to draw attention. Thanks, Tim D. Hotze

Hard drive jumper settings required.

by dseagrav＠bsdserver.tek-star.net

I'm going to attach this to the QD21, so I need to reset the jumpers. IBM 115MB ESDI drive, type 0669, sequence # 104040108 There are 6 DIP switched behind the drive terminator. I'm told I have to use a straight-through cable, so I went and got one. The drive does nothing. With a crossover cable (Where the pins are crossed, a normal PC cable) it went click-clunk, click-clunk, and did nothing. The drive is known good. (I pulled it from a PS/2 which we upgraded to a SCSI drive) If anyone works at Advanced Technology Services, the drive came from Cat origionally and has the ATS sticker "ATS-444862" Another barcode on top of the drive by the air inlet says "B1AF3092241"

8-bit Atari's

by thedm＠sunflower.com

No it's not normal at all I must have pickedup 20 atari computers and have had no dead ones. They are generally pretty reliable hardware, the floppy drives however are another matter, they need to be speed calibrated often. ---------- > From: Asterisk <ampage(a)geocities.com> > To: Discussion re-collecting of classic computers <classiccmp(a)u.washington.edu> > Subject: Re: 8-bit Atari's > Date: Monday, November 03, 1997 12:48 AM > > I have a weird problem with Atari 8-bit stuff... > I have a 1020 printer, an 850 interface, and a 400 computer, and two 9v > AC power supplies.

Need Jumper Settings...

by photze＠batelco.com.bh

Hello. As you may/may not know, I'm working to get a XT working; but I don't have to many of the origional componets. I have the origional XT's monitor and case, but my graphics card is by Multitech, mostly with Chips by a company called Chips (They made the graphics stuff in the IBM Thinkpad 365ED's.), and it's model number (I guess) is PB85101. It does have a composite video adapter on the end, as well as a monitor connection. There are two large processors identical in size and shape to the 8088 (but it probably isn't), but made by Chips. There is also a bus adapter, chips are also made by Toshiba and TI on this thing. It has EGA stamped all over it, so I'm wondering what I should do. Thanks, Tim D. Hotze

Spectrum case colour

by pjoules＠enterprise.net

Hi, I got a Sinclair Spectrum +2 at the weekend from a car boot sale complete with a light gun and in its original box with about 50 game cassettes for 20UKP. When I used to have one of these many years ago I seem to recall that the case was grey but this one has a black case. Does anyone know if they were made in different colours and, if so, what the significance of the colours was? Regards Pete #include <std_disclaimer>

I don't know if I'm getting one; it appears that PG Manney's E-mail is a work adress, or he was away for the weekend or something. >Ah, one of the good TV's.

You might want to check in the Afeas (how ever it's spelled) catalog, as they're made for military families, so they ususally have things like that if you still want one. Thanks, Tim D. Hotze
