Apple IIC+ Pointers on getting programs to and from machine.

by ron.hudson＠sbcglobal.net

I want to start getting some of the BASIC programs I am writing on my IIC+ out for sharing, I also want to be able to make use of some of the disk images out on the internet (apple.asimov...) How can I do these things? URL's for good web pages? Anybody else into Apple II?

OT: Other collecting activities? - Digital Stereo camera

by Innfogra＠aol.com

Reading my previous post it looks like it came from Zane. Sorry I forgot to sign it. I do like my Optio camera but it shows some of the limitations of earlier cameras. It is probably the last of it's line. Lots of manual options is one of the reasons why I like it. The limitations are two "f" stops and only 100 & 200 ASA Paxton Astoria, OR.

PC boards and software

by charlesmorris＠direcway.com

>If you can settle for 4 x 6 inches (roughly), you can get everything >needed for $125. That seems not too bad to me, for software I actually like >to use, as opposed to "can get by with". Actually 160x100mm (Eurocard size) which is 6.4 x 4 inches... never seems to be quite big enough! I bought the nonprofit version for $125 or so which has that limit. >Agreed, the $1200 (that I paid) for the unlimited version is a ton of money >for software. (Maybe you are the target audience for PCB123 :-).) $1200? I thought the top of the line was $495 (which IMHO is still a ton of money). Meanwhile, for PCB shops I have been very happy with Olimex (www.olimex.com) in Bulgaria. If you're not in a flaming hurry (airmail takes about 10-12 days but is only $8) they will make a Eurocard-sized two layer, silkscreen, solder masked board for $26, directly from your emailed Eagle .SCH and .BRD files. Turnaround time is 3-5 days not counting the airmail. -Charles

I had just got home with them and haven't checked them to be sure but they look like Multibus. Let me go check. Nope, it's not. It's not as wide as a Multibus card and the contacts and contact row are narrower. Rats! Joe > > >> >

PowerBook 170 question

by gehrich＠tampabay.rr.com

I just acquired a Power Book 170. Hopefully it is old enough to be on topic here. It looks to be in great physical shape but I have a few questions. When I plug it in there is a mouse pointer and a small blinking diskette. 1. What do I do next? What disk is it looking for? 2. Should there be a hard drive in this computer? 3. If there is a hard drive why should it be looking for a diskette? 4. Battery does hold a charge ================================= Gene Ehrich gehrich(a)tampabay.rr.com

I used to have about a 75% successful launch rate. The others would tend to clog the nozzle and blow up on the pad. I even made a two stage that the second stage went out of sight. A couple minutes later, I saw the smoke trail and recovered the top stage. All great fun. Dwight

DEC VAX 785 and PDP11/70's in Kansas City

I'm a frelling long way from Kansas (New York) but I could seriously use an RM03 or two for testing against the Setasi emulated RM03 setup on my pdp-10s(s)...

Write protect tags

by dwight.elvey＠amd.com

Hi I just saw something interesting on ebay. Now for years, I've been carefully placing the tags on the disk nice and square. I even pre-bend them so that there is little or no force pulling them off the surface. Still, one or another will eventually snag on one of the corners and lift up. Well, I just saw a disk with the tag mounted such that it was diagonally mounted( looks like a little triangle >from each side ). There are no parallel edges to catch on things as one slides the disk in and out. The sharp corners that might catch are on the edge of the disk and unlikely to cause the tag to lift. Has anyone else tried this? What do you think? Dwight
