Applefritter has a Hotline server as well: https://www.applefritter.com/content/university-misfire I have fond memories of using Hotline (and Carracho) on the Blue & White G3 at my job in 1999 on a 128kbps IDSN connection. Lightning fast compared to the 33.6 modem at home!

The Outbound Laptop Mac clones from the late 80s have an interesting feature called the Silicon Disk. It's basically a RAM disk, but uses dedicated SIMMs that aren't shared with system memory. As long as the Outbound has power, it will preserve the contents of the Silicon Disk, even if the...

Apple needed to include at least an external SCSI port so users could attach peripherals, as FireWire wasn't around at the time. Since that meant including a SCSI controller, it would cost practically nothing to include an internal SCSI bus as well. Switching the CD-ROM and Zip interfaces to IDE...

I mean, it's not an impossible task, but the service manual assumes you're performing the adjustment with the system powered on (so you can watch the image change). One could instead do the adjustment iteratively, where you power down the machine, discharge the CRT, adjust it a little, then...

Fixing a rotated screen image involves physically turning the yoke assembly at the rear of the CRT...I don't think the circuitry from that era supported rotating the image in software. The procedure is documented on page 129 of the Color Classic service manual. Doing the adjustment requires more...

My two cents: Since leaking capacitors can cause damage, replacing them -- even in a rare or historically significant machine -- would be considered an act of preservation.

Managed to find some answers. The RJ-11 keyboard cable is officially called the "infrared bypass cable", though I still haven't found a pinout. The mini-DIN jack is for an optional mouse that Outbound sold, which was *not* ADB, and could share the keyboard's IR connection to the main unit. The...

If not for an anti-glare filter, then my guess is it's for one of those copy arm things.

1. The keyboard can work either over infrared, or with an attached cable. The keyboard has two ports, an RJ11 (with matching RJ11 on the Outbound itself), and a mini-DIN. What's the pinout of the RJ11 cable? And what's the mini-DIN for? 2. You could get the Laptop with either an internal floppy...

That store was in the same location in the mall for close to 20 years. I remember getting a chuckle when Microsoft opened a store directly across from it, and also showing up at like 8am one day to watch the simulcast of a keynote (probably in 2003). A couple years ago the store moved into a...

I definitely agree with the ego aspect. Growing up we had a 575 as the family computer, and only upgraded it to 12MB total. We never had problems due to limited RAM after that, and that's with using the machine for actual productivity (as opposed to the goofing around we generally do with our...

In case you don't have them, it looks like the drivers are still available for download from Logitec's site (Google Translate link): https://www-logitec-co-jp.translate.goog/down/soft/if/lubsc.html?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=wapp They list OS 9 and OS X drivers, but they...

Back in the late 90s, after buying an iMac DV, I picked up an Entrega-branded USB-to-SCSI adapter so I could keep using my Zip drive and scanner. To say that the adapter was flaky was an understatement. I could never determine whether it was hardware or driver related (honestly, probably both...

My experience is that the LC 5xx (and Color Classic) need FPM. Interestingly, while the Apple Developer Note for the 575 says that modules need to be 80ns or faster, it doesn't offer much else in terms of specifications beyond mechanical drawings and pin assignments. The 575 service manual...

I'll echo the sentiment to not overextend yourself, but also offer the suggestion to reconsider your video style or workflow to make episodes quicker or easier to produce. For example, instead of primarily doing pieces to camera (which, as you've said, you have to shoot at work due to noise...

Several years ago I bought a Hioki DT4252 and haven't regretted it. It's made in Japan (with build quality to match) and has a solid feature set. Hioki isn't a big name outside of Asia, but from what I've seen they have a very solid reputation. The price has gone up a bit over the years; it...

What's funny is that while the final production eMates only came in green, the replacement styli (like @ScutBoy has) came in the same colors as the prototypes. I have an orange replacement stylus for mine that's the same shade as in the above photo.

IIRC pretty much all of the parts are interchangeable between the 520 and 540 models. The service manual lists a "540c Upgrade" kit that was sold (page 168 in the PDF), which would replace a 520/520c/540's screen with the active-matrix panel from the 540c. It's possible that the display ribbon...

My two cents is that the very inexpensive printers aren't a good idea for people who are new to 3D printing. They seem to be fussy and require some knowledge to get working properly. If you can expand your budget, the Prusa Mini for $349 (or $399 fully assembled) is an excellent way to get into...

I've used Kapton successfully many times as a way to protect SMD components from accidentally getting desoldered when I'm doing rework. However, that's usually when I'm putting the replacement components in place, in case I slip with the soldering iron. For hot air work I'll use pieces of...
