The most common monitor in 1979 was the Sanyo model VM4209 monochrome 9" monitor pictured above. There were no "computer" monitors on the market, and the little Sanyo security monitor was the least expensive and a perfect match for a Disk][ atop your Apple][. Mine pictured here...

I remember a HabaDisk for the Mac. 400K external drive with 19-pin D connector. Was there one for the Apple II? The Mac drive turned out not to be compatible with later system versions.

Right. There was an LCD panel that went on an overhead projector, called the Kodak Datashow. I believe it used a DIN-8 to bring the Mac video out. We designed a NuBus video card that put out 512 x 342 monochrome video same as a 9" Mac to use the Datashow with a Mac II. There were a lot of...

It's a MacPaint "pict" file. Open it with MacPaint, or on a modern Mac, select it in the Finder and hit the spacebar or use Preview. Not many modern apps support the old file formats. Tried to open one of your old MacWrite docs lately? The only reason Finder supports pict is Steve wanted to show...

Are you sure your SCSI drive has a system that will boot a Plus? The symptoms sound like a software crash. There may also be some oddities about booting a Plus with a 68030 chip. What happens if you boot from floppy with HD attached? Termination / term. power OK for a Plus? Remember the Mac+...

OK. Took many tries before I found a chain of Macs that could read a 400K disk and write to mobile me. 520c floppy -> HD -> ethernet -> Cube (OS9) -> reboot Cube (OS X) -> Mini -> internet. Things that didn't work included 128K (upgraded) which couldn't AppleTalk with OS 9...

Here's a web-based copy: http://www.folklore.org/StoryView.py?project=Macintosh&story=MacPaint_Gallery.txt but you'll need to convert it back to pict format for MacPaint.

Look for a copy of the Apple II Reference Manual, the DOS 3.3 Reference Manual, and the Applesoft Reference Manual. If you haven't used an Apple II before, you'll need manuals. The old machines don't work like Macs and Windows. They give you no clue to what commands they will accept at any given...

I'm sure I have it. I'll post it to mobile me / iCloud or whatever it's called, but first I have to: 1. Dig deep in the closet for my big box of old floppies and find MacPaint. 2. Dig out and fire up some old Mac with a floppy drive and find the picture. 3. Get it on the network and copy the...

Looking at the pictures, you have a Plus and a 68030 accelerator with FPU. The 64-pin connector on the side might be a CPU passthrough. Right number of pins. That's a Plus motherboard, and Hyperdrives for the Plus are ordinary SCSI drives mounted inside the case. The bracket held a drive, fan...

My mistake. I meant to say 27C256, the 32KB EPROM. Two of them for 64K of ROM. Pin 1 on the 27C256 is Vpp, the programming voltage pin which needs to be at 5V for normal ROM read. See here: viewtopic.php?f=7&t=15556&p=148698&hilit=27C256#p148698

Most common "no Sound" is a bad cap between the Sony sound chip and the speaker. Instead of 10 or 100 MFD, at this age, they commonly measure <1 MFD. An oxidized contact on the headphone jack is possible, but I haven't seen that myself. Capacitors which have lost most of their capacity also...

The danger from high voltage is that it might go through your heart, and if it does that at just the critical part of your EKG cycle, it could put you into fibrillation. Sounds scary, huh? So the old tube TV and guitar amp guys' rule is, if it's hot or you don't KNOW it's safe, keep one hand in...

Don't worry about over-stressing the Mac. It's old, and it's probably been unused for a long time, so it wouldn't be a surprise if another capacitor gave out, but using it won't shorten its life noticeably more than leaving it turned off. It's not useful for current work, so you won't be running...

I'm not familiar with the Lisa Widget drive, but a lot of drives of that era had head stiction problems. The heads would stick to the platters when stopped, usually at the edges of the working surface where the heads sweep the lubricant. Though the brakes release, the disk fails to spin because...

I find looking in my box of old ROMs, a set of 342-0220/21 (no letter), a set of -As and a set of -Bs, so I guess I have both versions plus a possible third version. There's also a set of Beck-Tech 64K upgrade ROMS which support large memory up to 4MB. Question: will a set of -A ROMs work in a...

A B&W can be a very usable Mac if you use a PCI card for hard disk controller, and don't use FireWire for large file transfers. The built-in IDE interface is useless on a rev.A and can be problematic on rev.B (some work fine, some don't). FireWire on all 3 B&Ws I've worked with start...

To answer the original question, I have an e-Machines EtherDock which works with my Duo 2300c. It works for file transfers and internet (as much as internet can be said to work with OS 8.0 and Netscape Communicator 4.08.) I have a second EtherDock which works when the moon is in the second...

ROMs for a 128K Mac can be replaced with 27C256 EPROMs with pin 1 lifted out of the socket and jumpered to pin 28. (Programming pin needs to be tied to +5V for Read Only useage.) If you can get the part number (there were at least 3 different "64K" ROM versions), I may have an original chip to...

This seems to be common. I have two drives with the same broken gear. I suppose the plastic becomes brittle with age?
