The Dutch Holborn System 6100/6140 is a very rare machine (and very funky design), only 100 of them were made. The system specifications: • Zilog Z80 CPU @ 3.5 MHz • 72 KB RAM (expandable to 192 KB) • 8-inch floppy drives

The Dutch Computer Museum has a working one, they made the video below

There's a block on my bench... oh wait no, it's a Kaypro. Same difference, just one we tricked a rock into thinking.

Kaypro's are a legendary luggable, that's right than thing was meant to be used on the go. Used is generous term, we'll get back to that. Tough and reliable, these machines found themselves in places that a microcomputer had not been seen before.

In this case for my collection the Kaypro is more than just representing itself, but also representing CP/M machines as a whole, a role that I think it works well in.

CP/M was a once standard OS, much like Windows is now, any company could build a Z80 based computer and license a version of CP/M for it! Once that was done, porting applications was trivial. The OS is extremely simple, the version here for the Kaypro is version 2.2G which is drive aware but has no concept of things like folders (Thats where you store your disks, right?) CP/M precedes MS-DOS (Or more accurately MS DOS is based off CP/M) The basic DOS command for switching disks and displaying a disk directory are identical. Launching a program is just as easy as typing it's name into the command prompt.

For a microcomputer, this system was more aimed at productivity, wordprocessing, spreadsheets and databases were all common applications for CP/M machines although games and BASIC could be found as well as other languages of the day.

Now I mentioned it's a luggable, which is to say, the system closed up could be moved around. It does not have any internal batteries and must be plugged in to run, on top of that this machine is not light, coming in around 40 lbs (19kg)!

I am that guy

Somewhere over food one evening I read a post that I cannot find.

Basically: Ancient computers running DOS/Windows 95 perform critical science with proprietary data sets and its some old guys job to maintain these relics because no one has figured out how to deal with old machines that just work.

I am that guy.

Someday, after the heat death of the universe, all my stupid skills and arcane knowledge about old computers, and steam power will come into need. How cool would it be to say "ya, I yeet win95 daily". My job is to make sure the old tape backup works. What's the phone number to that modem? I need to do a data transfer. Floppy disks? Got one of them cool 2.88mb IBM double density drives?

It was a time of interesting things. Now, I can do all that on my pocket computer. But that's just somehow not as fun.

Anyhow, I can't find the writeup, but if any science institution needs an old tech guy, I am available.

Just 40 years ago top of the art. Now something of the past. Time goes so fast. 4 more years will go by like seconds. Don't worry be happy!

The Zorba was a portable computer running the CP/M operating system manufactured in 1983 and 1984. It was originally manufactured by Telcon Industries, Inc., of Fort Lauderdale, Florida, a company specialized in telecommunication equipment manufacturing.

The Zorba was one of the last CP/M computers on the market. By the time it was introduced, the Kaypro and Osborne machines already dominated that market. The introduction of the Compaq Portable, compatible with the IBM PC and running MS-DOS, sealed the fate of the CP/M machines.

I bought one of these in 1983. Worked great and still works. Best display and keyboard for writing that i have ever used.

What do you think about this Mobius variant? 🤣

Behold my first of many unfunny memes!

I’m sure I missed a spell for dnd, but permanent body changes are surprisingly not available at lower levels, I think.

I have one of these. I used it three years in grad schools to type papers and program in Turbo Pascal. It still sits in my closet.

JunJun In A Canon CP: The Evidence

Sword Chaos, his first drama appearance in 2016, gave us this lovely, blurry tease: (more blurry evidence under the cut)

The girl's face says it all.

#he was in a canonical m/m CP in his first drama#then starred in a BL#THEN starred in a spin off series where his character falls for what he thinks is a man#just sayin

PC/GEOS aka GeoWorks. Great OS, much better than Windows 3.11
