Re: I recreated the Apple Lisa computer inside an FPGA [video]

I've recently finished a project that implemented a mc68000 microcomputer board for a 80s industrial control system. It's a great way to do a deep dive into micro computer design, and the older technology makes it possible for 1 person to have a pretty decent understanding of how the system works. Implementing the programmable timer modules was definitely a challenge to get them cycle accurate.

I really want to adapt what I've done into an amiga500 accelerator board.

Interesting. I used Apple II's in elementary school (early 1980's) and then some Macs but I had never even seen a Lisa in person until going to a computer museum about 5 years ago.

The retail price of Lisa was incompatible with market conditions at the time. https://youtu.be/1kshrfvkLZE?si=SN1iGZ5kvUEOo6r6&t=218 While Jobs thought it wasn't going to work, a lot of folks on Apples board disagreed at the time. A controversial character at times, yet both Jobs and Woz provably understood their customers better than most. =3

No one knew the market at the time. Clearly this was for large businesses and not a home computer. It targeted the same demographic as the Xerox Star which shipped before it and suffered a similar fate. No one knew what would work, easy to see in retrospect but at the time it was not easy to see. Apple also had a big disadvantage in the ‘office’ marketplace having no sales force that everyone assumed was necessary. Besides price, Xerox’s other problem was while they did have a sales force they only knew how to sell copiers. I suspect only IBM at that time with a product like the Star or Lisa could have succeeded. But the Mac was a completely different product for a different marketplace and even it was a failure at first—until desktop publishing turned things around.

What's cool about this is that we're at the point where a committed hobbyist can pull something like this off. I don't know what's in the FPGA, and I honestly don't know that much about FPGAs, but I imagine it's a pretty much "drag and drop" of the Lisa logic board schematic rendered in whatever FPGA language is used, while leveraging as many, stock, "off the shelf" cores as necessary. It's telling that they external…

> But the point is that FPGAs are that accessible today. They've been accessible for a lot longer than most people think. The original Minimig project (an FPGA recreation of the Amiga chipset, coupled with a real 68000 CPU) started in 2005 - more than 20 years ago! And 15 years ago there was already a complete Amiga core (chipset and CPU) running on the Terasic DE1 development board, the C-One FPGA computer, and the…

Accessible for development, sure. Developers and hobbyists are willing to pay $500 for an FPGA devkit, and that's been possible for a long time now.

But, more recently (last 10 years), we've seen increasingly-low-LE FPGAs on increasingly-minimal FPGA breakout boards, with no educational subsidies required to make the boards cheap. There are FPGA boards you can play with for under $50 now; and some around.

This is so neat! There was a list entry for a Xenix HD image, I'd love to see that in action.

Xenix is the best operating system Microsoft ever shipped, but they gave up on it because there was no way they could use their PC leverage to corner the Unix market.

What did Xenix did that was so distinctive?

It was a fascinating idea - programs were hidden behind a document template metaphor. It was not as neat as Windows “New” menu and its templates folder.

Also kind of makes sense out of the concept of "Desk Accessories" (i.e. the things under the Apple menu in Macintosh System 1 — Lisa OS also had these.) Every Lisa OS "task" (there were no processes in the pre-emptive sense) is either running a program in the context of a document that program manipulates; or is a document-less accessory program, running under some other task.

8 months of work, and it shows. Phenomenal result!

The thing that blew my mind as a kid on the original Lisa was the power button. You pressed it and it didn’t immediately cut the power like a PC, it was a request to cut the power and the OS would first clean up various things on the desktop before finally cutting the power on itself. It just seemed to have agency and a type of control over itself and its environment that gave an impression of intelligence.

$10k for a home computer enthusiast is still a big ask in modern markets. Have a great day. =3

There was animosity between Steve Jobs and the Lisa team (who perhaps not coincidentally chose to name the system after his daughter). Once he decided that the Mac would compete against the Lisa, the Lisa platform was doomed. Jobs basically told customers, software developers, and the press that the Lisa was obsolete because the Mac was coming out soon and would be cheaper and better. He was correct about the cheaper part.

Unfortunately the Mac cut a lot of corners for affordability. The original Mac had only 128K of RAM, and Jobs didn't want to offer memory upgrades (he thought you should just buy a new computer - sound familiar?) It took Mac OS 16 years to get memory protection, which LisaOS had in 1983. Lisa didn't need to die - it could have merged with the Mac and made the latter a better and more reliable platform, years before Mac OS X.

> at the time

Isn't that interview from 1995, years after the Lisa (and Mac) came out, and long after Jobs had left Apple (but before his very successful return)?
