The cheap small "brick" multimeters are available everywhere and are more or less junk. I've used several of them and they're super inaccurate and/or the dial stops working properly, so you have to...

You could try Snooper, it can detect various hardware problems.

There's a datasheet for the VDP ( HD63484CP98 ):
https://pdf1.alldatasheet.com/datasheet-pdf/view/144401/HITACHI/HD63484CP98.html

Looks like it supports up to 16 bit color and up to 4096x4096...

Has your install of System 7.1 previously experienced any crashes from misbehaving applications like MacDraw? It only takes one system crash to cause file system corruption. The Hierarchical File...

I have 16 MB on my board and while Gemstart can see that it has 16 MB, increasing the available memory with the slider instead uses the hard drive as virtual memory.

Another problem is the...

The problem you're having with MacDraw is running a 24 bit program on a 32 bit CPU and OS.

MacDraw is an ancient 24 bit program released with the original 1984 Macintosh. Most Macintosh computers...

I'm guessing you have the TotalSystems Gemini Ultra upgrade board, at least that's what it sounds like. I have one of those boards too, and it's actually faster than an SE/30.

The only problem is...

If the motherboard can't properly determine the CPU speed at 200 MHz, it very likely doesn't support it.

Many motherboard vendors in the 1990s often included bus speeds and multipliers that didn't...

I have both a regular SE and a SE FDHD and they're both identical in terms of board placement. The only difference is the FDHD has different holes stamped in the metal plate between the logic board...

You can't just replace the ROMs and floppy drive and it will work. You also need to replace the IWM floppy disk controller with a SWIM floppy disk controller to be able to read and write 1.44M disks....

There's really not a lot in the realm of "specs", all Macintosh SE machines are the same, bar the RAM and storage options. They can come with 1, 2.5 or 4 MB of RAM and either one 800k floppy drive...

If you don't want to go through the aggravation of making a new stake to replace the broken one, you can try super glue. As long as you don't go conan on the key, it should hold well enough.

I'd say check for shorted components, like the C1/C3 capacitors which look to be tantalums. The next thing would be to check the 74 series logic chips. If none of those are bad, the most dreaded...

With those ping times, it sounds like you had some sort of satellite internet like HughesNet.

Dialup is of course going to have a far lower latency because the satellites that most current...

The "fastest" Netburst by clock speed was the Prescott-2M Pentium 4 672 at 3.8 GHz, and its Xeon equivalents. But the raw clock speed doesn't have the grunt to back it up. For Intel to ramp up clock...

They've done it in bad faith, they're basically a scummy patent troll company.

They joined the JEDEC in the mid 90s and when they didn't agree to reasonable patent and licensing fees as required...

Windows 9x was not really designed for high LAN speeds, the OS is a bottleneck itself. But more importantly, so is the whole system. Slower CPUs will have a slower ethernet speed because network...

Yeah, it's a totally awesome memory standard not good for anything!

RDRAM being paired with the Pentium 4 was a really terrible idea. Netburst was a weak architecture to start that required lots of low latency cache and low latency main memory to perform halfway...

Jafir posted a link to one on the first page that will work. 44 -> 40 pin IDE adapters are completely passive, all they do is split the data and power pins apart.



We know what those are, it's...

I've had decent luck with this one $20 Ebay special component tester:

The only problem I've found with it is that 47uF capacitors aren't detected at all,...

Bad connection, marginal drive or bad power supply are just a few possibilities. When dealing with 30+ year old hardware, anything is possible.

The days of CHS addressing were dark times. I remember having more than a couple of machines that would crash in the BIOS if the CHS geometry went beyond a certain size due to stack smashing.

FTP requires a TCP/IP or PPP connection between two machines, it cannot be used by itself since it relies on an OSI layer 4 transport protocol to work.

Connecting two modems together directly...

I can say that they work in the short term if you get the length correct, but I've not done any long term testing with them.

Are you sure your printer can't print TPU? Most any printer with a...
