The datasheet says that the 88920 is for slower 20 - 25 MHz operating frequencies. And that the 88916 isn't suited for the slower speeds. Click to expand... Just curious - wh…

Ok so far no big losses. I guess I'll stick with my SE/30.

Magaroids will only work on a Mac 512KE and earlier. It won't even work on a Plus. I think that Arkanoid won't work on anything later than an SE (maybe a Classic).

Just as the opposite example. Missile Command is a game written in 1984 for the Mac 128k and System 1.0. It also runs on the latest Power Mac G3 system with OS 9.2.2.

I know for a fact Dinosaur Discovery Kit (from First Byte) doesn't work on SE/30s. This was explicitly stated in the third edition of the Macintosh Bible. (It supposedly only works…

Probably anything that didn't follow Apple's programming guidelines and made undocumented Toolbox calls and the like.

This may sound like a dumb question, but are there any classic Mac games that will run a 68000 Mac but not on the 68030 SE/30? I know the Atari Falcon (a 68030 machine) had all ki…

I checked the fit of all the socketed items and they're all as tight as they can be. The RAM looks brand new and is also in tightly. I guess it's the capacitors then. I have an …

Ditto Tom Lee's excellent advice. Moreover, it could be iffy fluid-filled capacitors as well. Heat does influence them.

The Plus should handle those ambient conditions ok. Perhaps you have poor connections that are particularly sensitive to changes in temperature. Common culprits would be RAM, as we…

.. folks seem to run at 20 - 25 MHz even after they've swapped in an 88916. There might be problems if the 88916 gets hot or otherwise loses margin, I imagine. Click to expand…

Tried Applefritter? I think he's a member there too. I'm assuming you've PMed him.

1. MC88920 has been designed specifically for the 20 and 25Mhz 68040 microprocessors. Click to expand... Yes, I noticed that when I reviewed the datasheets last week. However…

Lots of people take extended breaks... He'll be back hopefully.

It's been six weeks since he's been on...

Glad to have ya! The first computer I bought with my OWN money in college was my trusty Quadra 630 - Nice sum of 1200.00 used from a Chinese lady on campus. That was 1992-1993 I …

The most primitive stand alone Apple LCD was the blue & white 15" Studio Display at 1024x768. It is a multi-sync display so it will display 640x480. The earliest LCDs from …

I posed this question on the "bringing back to life" thread but did not get any response most likely because I slipped it in as an afterthought. Although it works perfectly, I wo…

I think I've figured it out, and it has nothing to do with Stuffit after all. The system is simply overheating. I turned it on yesterday evening and everything was working just f…

OK, if you're using 20 MHz oscillator in your mod, would you mind telling me where that 40 MHz signal for the processor comes from? :-D Click to expand... Well, apparently eac…
