The monthly Southern California TRW Ham Radio and Electronics Swap Meet is being held this month (May) on Saturday the 29th, from 0730 hours to 1130 hours local time, at the TRW facility in El Segundo. Take the san Diego (405) freeway, exit Rosecrans, go West about 1 mile to Aviation (under the Metrolink bridge), turn left (south) on Aviation and proceed 1/2 mile south. The TRW facility will be on your right, and the Meet is held in the southernmost parking lots, bordering on Marine avenue to the south. Find a place to park and come join Marvin and myself, although I will certainly have gotten all the choice goodies first, (unless Marvin beats me to them). I am in spaces J21 and J23 and any classicmpers who will be in the area are cordially invited to join us. I have space available for anyone who might wish to unload some ju^H^H^H^H vintage items on the swapmeet attendees. There will be the usual after meet Brunch-n-Brag, at about 12:30 at a restaurant local to the swapmeet; all are invited. I am considering another collection Open House at my place, but that depends on feedback. E-mail me privately for further information/data/whatever. Cheers John

Apple Monitors ??

That's how I have mine. 80-column is barely readable.

Upon the date 09:41 AM 5/19/99 -0700, Fred Cisin (XenoSoft) said something like: >> ** Kingston cooling fan/power switching module.

Nah, seems to be the same thickness across its length. Too narrow anyway.

I didn't mean modern like IDE disks, though that's an idea. I meant modern for the PDP-8 in general (RL8A/RL01, RK8E/RK05 vs DF32 and RF08). Sorry I wasn't clearer; I was in a hurry this afternoon. -ethan _____________________________________________________________ Do You Yahoo!?

Scientific Micro Systems

by edick＠idcomm.com

Regardless of the physical size, (maybe 13x15") if they are FT400 or FT300 models, then I may have useful information regarding their use. These models are FDC-only with a very easy programming interface. Back when I used a 1 MHz 6502 for much of the work, I used one of these and was probably the only one around with double-density capability as a result. The interface was dirt simple, yet could keep up with any processor of the time.

Tossing

by Philip.Belben＠pgen.com

> AFAIR did Philip suggest RLLRRLL (or more neat RLLRLRRL) ... RLLRLRRL? Nice! I like it. (Sam - if you think it's important, make some right angled trapezia from cardboard or even paper and arrange them on a flat surface with a line as the floor. You'll see what we mean.) Philip.

Amiga A1020 5.25" floppy drive (was Re: Atari modem)

by gregorym＠cadvision.com

It can be done, but I don't remember how. A lot of my friends transitted >from C-64s to Amigas, and at least one of them had hardware that let him connect the 1541 directly to his Amiga to do file transfers. I don't remember if it was just a cable and some software, or if there was a hardware interface involved. A quick post to comp.sys.amiga.hardware should find someone who remembers. Regards, Mark.

plated-wire memory

by yakowenk＠cs.unc.edu

How similar is plated-wire memory to core? Does it have the same wire-matrix organization, but is dunked into some magnetic gorp rather than having little torii strung on? Bill.

I would. I collect rotating memories, and obscure interfaces thereto. It is a small sub-speciality of mine. :^) Jeff On Tue, 18 May 1999 08:03:09 -0700 Mike Ford <mikeford(a)netwiz.net> writes: >>SMS was the maker of a number of 8X300-based FDC's.

Paging William Donzelli

by yakowenk＠cs.unc.edu

Has anybody out there had recent contact with William Donzelli? I've got two e-mail addresses for him, and both bounce. And it looks like he hasn't posted anything to classiccmp for nearly a month... Bill.
