0xc1900201 error installing Windows 10

Are you getting a 0xc1900201 error installing Windows 10? I got both that and 0xc1900200. Here’s how I fixed it.

I upgraded my venerable Dell E1505 to Windows 10 over the weekend. It was harder than it needed to be, but I got it running. It’s an old machine, but the CPU is fast enough to run Windows 10, and if you max out its memory and put an SSD in it, I think it may even run Windows 10 better than it ran Windows 7.

Here’s how I got it working.

The silver label Commodore 64

The most valuable examples of the Commodore 64, generally speaking, are the early variants that have silver labels across the top. The silver label Commodore 64 is the earliest, most expensive example of the venerable machine.

In all, Commodore produced about 80,000 of these machines. That compares to several million of the most common variants. That alone makes them relatively rare. When you do find one, there’s a fairly good chance it’s not 100% original.

Solve the NSIS error

nsis_errorI was trying to install some software last week and I got an NSIS error like the one to the right. The message certainly suggests corrupt downloads, but corrupt downloads are relatively rare, and when they happen, redownloading it ought to clear that up. Getting two of these failures in a row with different programs is really a freak occurrence, so I started looking for another problem.

Origin of CP/M’s PIP command

CP/M was, as you probably know, the first popular microcomputer operating system. It was good but imperfect, and its cryptic command for copying files, PIP, is often cited as an example.

Copy makes sense. Even the Unix equivalent, cp, makes sense–it’s copy without the vowels. But what does PIP mean? What’s the origin of CP/M’s PIP command?

New computer, old monitor

New computer, old monitor: I see questions fairly frequently about using a new computer and older monitor together. More often than not, it’s possible to do, but you may need to know where to look for the cables and adapters you’ll need.

Here’s some help.

Gary Kildall’s death investigation

I was selling computers at retail when I heard of Gary Kildall’s death. We had a few copies of Wordstar for Windows and someone asked about it. I said it was easier to remember the keyboard shortcuts in Wordstar than Wordperfect.

“You sound like a CP/M guy,” said someone who overheard me. “Did you hear that Gary Kildall died last month?”

I hadn’t, and he wasn’t surprised. I was curious, so I went to the library and found a whole lot of nothing. A month or two later, I found a mention in a computer magazine column that Kildall had died in a barroom fight but it gave no specifics.

Catch up on Microsoft patching fast

Last week, Microsoft quietly released its convenience update pack for Windows 7, 8.1., and Server 2008R2. This is a great opportunity to catch up on Microsoft patching, as it incorporates all of Microsoft’s OS-level updates from the release of Service Pack 1 to April 2016.

Here’s how to use this to clear your corporation’s backlog of Microsoft patches. No, I haven’t seen your corporate network, but I’ll bet you have one.

Commodore 64 vs 128

The Commodore 128 was introduced in 1985 as an upgrade path from the Commodore 64, the most popular model of computer of all time. The 128 was intended to address the biggest shortcomings of the 64 while remaining mostly compatible with its hardware and software. That makes the Commodore 64 vs 128 a natural comparison.

Commodore 64 vs 64c

The Commodore 64 went through a number of revisions throughout its long life. The most outwardly visible of those revisions was the transition from the tan, boxy C-64 to the thinner, lighter-colored 64c. If you’e wondering about the Commodore 64 vs 64c, here’s what you need to know.

C64 vs. Apple II

The C64 vs. Apple II was perhaps the most epic battle of the 8-bit era. Both companies sold millions of machines, yet both nearly went out of business in the process.

Comparing the two machines with the largest software libraries of the 8-bit era is a bit difficult, but that’s what makes it fun. The two machines are similar enough that some people ask if the Commodore 64 was an Apple product. The answer is no.

As a weird aside, it was possible, with a Mimic Systems Spartan, to turn a C-64 into an Apple II. Not many did, but the reason why is another story.
