That's a Plus rear bucket that's had the 512Ke labels stuck on it, no?

Not unless you want it to. Just for the **** of it, when I first got my Apple ][ in 1977 with a meaty 16K of RAM, I decided to calculate pi to 1000 places. It took the little beast most of a weekend to run it, but it came out right to 999 places. Truncating error on the last digit. Shoulda...

A subject of some humorous debate on Cubeowner.com. What is a Cube? Original? Certainly. Hot-rodded? Those who have a "daily driver" cube have all hopped up the CPU and GPU, installed big HDs and beaucoup RAM. Of course those are still Cubes. What if the hopping up involves a micro-PC...

Older houses seem better because the shoddy houses built 100 years ago have already fallen down. ;) You do have to wonder how long the glues that hold all the modern OSB, plywood, and MDF materials together will last. There was some very slipshod work done during the housing boom when anyone...

Usually so. Program segments ought not to be modified, so are read-only. Data segments are written to disk as needed. Have you ever gotten in the dread floppy-swappy cycle where you have to swap a couple of floppies in and out of the drive 20 or 30 times to get a program launched? Floppies are...

Yes, it could. I designed it so the pixels were clocked out at 14.31818 MHz with color burst like an Apple II, thus turning MacPaint fill patterns into colors. ChromaTron, see? :lol:

To get the board to work (as 128K) you need to plug 74LS244s into the 2 big sockets, and resistor packs into RP2 and RP3. The resistor packs need to be 10 pins each with 5 individual 47 Ohm resistors. To make it work as 512K you will need one of the little decoder boards or piggyback a 74LS253...

It ought to be safe. The 64K ROMs will only recognize 512K of RAM and won't initialize the SCSI port, but it should be safe, ie. no smoke. It was common to have Fat Macs with added RAM and SCSI upgrades, and they were essentially Plusses with 64K ROMs. The only fly in the ointment might be that...

It could, but it could just as well be an NTSC converter. Since Macs have their own display, there's no native NTSC or PAL video capability. I have seen a few people who did user group demos all the time who had a TV projector, back before computer projectors were common, and they had scan...

Of course, that's 2.5MB! :I

Could be oxidation on the ribbon cable where it connects to the mobo. Unlatch the connector and wiggle the cable, then latch it again. Good luck. Yeh, the Duos are heavy as iBooks, not so thin & light as the Air.

That's a most peculiar board. There are RAM chips it looks like, and it takes power from the MB power connector. Could it be a video card designed to drive a standard 9-pin CGA monitor or a TV monitor thru an RCA jack? I've never seen anything like it. 8-o

It is possible, but since it was much more common to upgrade the motherboard than to add a daughterboard, the mobo was nearly always upgraded first. The guys at MacMemory started out doing 512K upgrades, and later made a larger version of the Beck-Tech add-on that held 1MB. Note also that...

Yeh, but they have more S-100 and pre-1980 stuff than they can display or store already. The newest item they have is a 20th Aniv. Mac, the next newest is an original NeXT cube. They look on G4s as low-end systems for resale, or scrap. At one point they had 30 iMac G3s out for $10, and when they...

Austin's Goodwill Compter Works is excellent, and there are several other computer recycle / resale operations, as you'd expect in a university town. http://www.austincomputerworks.org/index.html Complete, operating systems are a bit pricey for us scrap hunters, but they put a lot of parts and...

I like the trackball better, too. Apple was inconsistent in where they silk screened the model number. 210s-270s usually had it on the bottom of the LCD panel, 280s & 2300s had it above the keyboard. The 2300 upgrade kit included a new 2300 series label for the bottom. Pictured here: 270c...

Sorry. In Preview, Tools menu, Adjust Size...

Your Mac shows 512K because it has the original 64K ROMs most likely. You actually have 1.5MB of RAM installed, it looks like. The mobo RAM chips have probably been replaced upgrading it to 512K and there's 1 MB on the MacMemory upgrade board. If you can find the original software that came with...

Preview can resize an image, among many other apps. Perhaps I don't understand exactly what you need. :?:

There was a refrigerator-size changer that used 2 drives and 48 of those 6-CD magazines at Goodwill last month. 8-o Quite the monster jukebox!
