Images for the poster set are taken from the manuals for the Kaypro and BBC Micro; thank you to folks who upload these online!

Fonts used in the textures are Nootrasim, Uni(versity) Llama, and Simlish Crayon.

-------------------------------------------------

Technical notes/known issues:

Sims’ hands slightly clip into the computers with angled keyboards; this is not something I can fix due to how the animations are set up.

The computers don’t have mice (they wouldn’t have had them at the time), so the Sims will move their hands around as if they were using an invisible mouse.

The BBC Micro computer has a medium decor slot on top -- perfect for cute plants, books, clutter, etc. In testing, I noticed that if you place something there that trails down the sides, Sims will not want to use the computer (you have to make them sit in the chair and then interact with it). Most items don’t seem to do this so I’m leaving the slot in - just know if you put trailing stuff on top, this might happen.

The cassette recorder has a decor slot in the perfect place to actually put the cassette tape in it, and I love it! I’d recommend picking the cassette tape you want before putting it in; once it’s in the recorder, I couldn’t figure out an easy way to get it out again. You can always delete the whole thing and re-place a cassette recorder.

Our teachers didn’t let us turn on and shut down the computers.

I am, however, this old:

And my computer lab was this era:

Kaypro II, Tandy TRS-80 Model 4P, Compaq portable - VCF Southwest 2023

[regretsretrotech]

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)!

Kaypro 4/84

[mechanical-creature]

Another 2022-present portable computer thing. This is a 1991 Corvallis Microtechnologies PC5-L. It's a ruggedized, waterproof handheld MS-DOS computer meant for industrial applications. It ran on Ni-Cd batteries and they died so now it runs on AA's I got two of them for $50 on eBay during one of those months when i impulse buy obscure electronics as a form of escapism This thing is an absolute brick. You could murder someone by hitting them on the head with this, and it would work fine afterwards. Here's pictures of its organs for anyone curious:

That thick red wire around the screen PCB is a heater. Yep there's a setting to heat up the LCD so it doesn't get sluggish or shatter when you decide to leave it in the freezer. The thing runs on a little system-on-chip thing, which is interesting to see coming from the early 90's. Iirc the datasheet says it's capable of analog video out as well as driving the LCD, but I haven't poked around enough to enable it. Might be cool to hook it up to a TV. I did, however, open those 512k storage modules and I saw some unpopulated footprints on the boards. So I ordered some of the same chips, and at some point I'mma try soldering them on and see if it recognizes the extra space. They came with two voltmeter modules, which I couldn't get to work, so I took one of the casings and made it into a USB and WiFi adapter using an ESP32 running Zimodem, since this thing has RS232 ports on the top. I also made my own charging adapter, since they didn't come with one. I see that internal PCMCIA slot, and I tried putting a CF card adapter in, and tried installing the drivers, but it didn't work. I'm not good at DOS tbh, and I know nothing of what this slot is for. I might come back to it later. I did all of this in 2022-23 and haven't messed with it since. Except to use it to talk to my Kaypro 4 '84:

More on that one later. I love portable computers !!!!!

Lawrence Tesler, Who Made Personal Computing Easier, Dies at 74

Lawrence Tesler, a pioneering computer scientist who helped make it easier for users to interact with computers, whether cutting and pasting text or selecting text by dragging a cursor through it, died on Sunday at his home in Portola Valley, Calif. He was 74.

The cause was not known, his wife, Colleen Barton, said, but in recent years he had suffered the effects of an earlier bicycle accident.

Mr. Tesler worked at a number of Silicon Valley’s most important companies, including Apple under Steve Jobs. But it was as a young researcher for Xerox at its Palo Alto Research Center in the 1970s that he did his most significant work: helping to develop today’s style of computer interaction based on a graphical desktop metaphor and a mouse.

Early in his Xerox career (he began there in 1973), Mr. Tesler and another researcher, Tim Mott, developed a program known as Gypsy, which did away with the restrictive modes that had made text editing complicated. For example, until Gypsy, most text-editing software had one mode for entering text and another for editing it.

Mr. Tesler was passionate about simplifying interaction with computers. At Apple he was responsible for the idea that a computer mouse should have only one button. For many years the license plate on his car read, “NO MODES.”

His first breakthrough at Xerox PARC came when he took a newly hired secretary, sat her in front of a blank computer monitor and took notes while she described how she would prefer to compose documents with a computer. She proceeded to describe a very simple system, which Mr. Tesler then implemented with Mr. Mott.

The Gypsy program offered such innovations as the “cut and paste” analogy for moving blocks of text and the ability to select text by dragging the cursor through it while holding down a mouse button. It also shared with an earlier Xerox editor, Bravo, what became known as “what you see is what you get” printing (or WYSIWYG), a phrase Mr. Tesler used to describe a computer display that mirrored printed output.

And Gypsy brought to fruition the idea of opening a computer file by simply clicking on a screen icon while pointing at it with the mouse cursor. Before that, files had to be opened by typing the file name into a command line.

“At Xerox he pushed a lot for things to be simpler in ways that would broaden the base of users,” said David Liddle, a veteran Silicon Valley venture capitalist who worked with Mr. Tesler at Xerox PARC. “He was always quite focused on users who weren’t also Ph.D.s in computer science.”

Mr. Tesler later joined a small team of researchers run by Alan Kay, a visionary computer scientist who had pioneered the idea of a so-called Dynabook, which would become the inspiration for today’s laptop computers. The group was developing a software environment called Smalltalk, and Mr. Tesler developed a system for searching for software components, which he named the browser.

“He can be hailed as one of the true pioneers of many important aspects of personal computing,” Mr. Kay said.

After attending a demonstration of the Altair, an early hobbyist personal computer, at a Palo Alto hotel in 1975, Mr. Tesler returned to PARC to alert his colleagues to the arrival of low-cost systems. His warnings were largely ignored.

He continued to press for less costly computers. In 1978, with Adele Goldberg and Douglas Fairbairn, he designed a portable machine called NoteTaker, a forerunner of luggable computers like the Osborne, Kaypro and Compaq machines of the early 1980s. But Xerox declined to commercialize the NoteTaker; only a few prototypes were made.

It was Mr. Tesler who gave Mr. Jobs the celebrated demonstration of the Xerox Alto computer and the Smalltalk software system that would come to influence the design of Apple’s Lisa personal computer and then its Macintosh.

Mr. Tesler left Xerox to work for Mr. Jobs at Apple in 1980.

“The questions the Apple people were asking totally blew me away,” Mr. Tesler was quoted as saying in a profile that appeared in IEEE Spectrum, the magazine of the Institute of Electrical and Electronics Engineers, in 2005. “They were the kind of questions Xerox executives should have been asking but didn’t.”

In addition to helping develop the Lisa and Macintosh, Mr. Tesler founded and ran Apple’s Advanced Technology Group, after which he led the design of the Newton handheld computer, although that proved unsuccessful. The group also created much of the technology that would become the Wi-Fi wireless standard, and Mr. Tesler led an Apple joint venture with two other companies that created Acorn RISC Machine, a partnership intended to provide a microprocessor for the Newton.

Although Apple eventually sold off its holdings in that venture, it would come to dominate the market for the chips that power today’s smartphones. The chip architecture created by the partnership is today the most widely used microprocessor design in the world.

Mr. Tesler left Apple in 1997 for a startup and later went on to work for both Amazon and Yahoo. He left Yahoo in 2008 and spent a year as a product fellow at 23andMe, the genetics information company. He was most recently an independent consultant.

Lawrence Gordon Tesler was born in the Bronx on April 24, 1945, to Isidore and Muriel (Krechman) Tesler. His father was an anesthesiologist.

In 1960, while attending the Bronx High School of Science, Mr. Tesler developed a new method of generating prime numbers. He showed it to one of his teachers, who was impressed. As Mr. Tesler later recalled, he told the teacher that the method was a formula; the teacher responded, “No, it’s not really a formula, it’s an algorithm, and it can be implemented on a computer.”

“Where do you find a computer?” Mr. Tesler asked.

The teacher said he would first get him a programming manual and then figure out where to find a computer.

One day Mr. Tesler was sitting in the school cafeteria reading his manual, which offered instructions on how to program an IBM 650 mainframe in the most low-level, arcane machine programming language.

A student walked up to Mr. Tesler and asked, “What are you doing with that?”

“I’m learning about programming,” Mr. Tesler responded.

The other student alerted Mr. Tesler to a program at Columbia University, which gave high school students programming time. He was able to use a university computer for a half-hour each week, teaching himself to program before he got to college.

He attended Stanford, graduating in 1965 with a degree in mathematics. While there, he became involved in a number of early projects that prefigured personal computing.

Mr. Tesler had early access to a computer known as a LINC when he worked as a student programmer for the Nobel laureate Joshua Lederberg. The LINC, designed by the M.I.T. physicist Wesley A. Clark, is believed by many computer historians to have been the first true personal computer.

Mr. Tesler’s first start-up venture was a programming consulting company located in a shopping mall next to the Stanford campus. He also used a mainframe computer to build a system to permit the student rooting section at Stanford football games to program elaborate card stunts. It was, Mr. Kay said, a forerunner to the ways in which modern graphical displays would be programmed.

In 1969, with two other scientists at the Stanford Artificial Intelligence Laboratory, Mr. Tesler created a design for a small computer and proposed it to the calculator company Friden. Although intrigued, the company declined to pursue the idea.

Mr. Tesler left computing for a short while after that and moved to an Oregon commune with his daughter from a short-lived marriage. Lack of work led him back to the Bay Area, where he would join Xerox PARC.

In addition to Ms. Barton, a geophysicist, and his daughter, Lisa Tesler, he is survived by two brothers, Charles and Alan.

At Stanford and afterward, Mr. Tesler was active in both the antiwar movement and the 1960s counterculture. He participated in an alternative school, the Midpeninsula Free University, where he taught classes, including one exclusively for people born under the sign of Taurus. In 1968 he taught a class titled “How to End the IBM Monopoly.”

Years later, as a computer scientist at Xerox, he remembered his activist roots, his former colleague Ms. Goldberg said. The Central Intelligence Agency was a Xerox customer, and when agency employees arrived for a meeting, Mr. Tesler attended wearing a trench coat and a fedora.

When you’re cutting and pasting, dragging the cursor over selected text and performing other common computer tasks, you can thank him.

My first computer was a KayPro II - what was yours?

My first computer was a KayPro II – what was yours?

The year was 1983 when I simultaneously bought a “state-of-the-art” KayPro II “portable” computer and enrolled in a Computer Science class at the University of Southern California. The class was required to earn a B.S. degree in Business Administration and I thought the computer would give me the edge, although I had no clue on how to use it. The KayPro II computer was created by San Diego…
