I was at Apple at the time of "Twiggy" development and was on the development team in the Peripherals division, as it was called at the time. I wrote test code for Twiggy drives, exercising the drives, reading, writing, logging errors, etc. I wrote and rewrote the code several times over in an effort to improve the test results. It seems management couldn't believe the high error rate and was sure the test code was incorrectly reporting a high failure rate. It wasn't. Twiggy did indeed have two read/write heads as you say, one on top (forward of the spindle) and one underneath (behind the spindle). The heads were mounted to a single fixture and so did not move independently. Wikipedia has a nice writeup if you want all the details. Macintosh was in development at the time of course and the prototypes we had were equipped with Twiggy. The Mac almost went to market with Twiggy, but Sony came along with the 400k drive just in time for us to use it instead.

Wow! Thanks for your comment. What an honor to hear from someone who was involved in development. Do you still have any twiggy related equipment or disks? I've been doing some historical preservation work, archiving twiggy based software and whatnot, and I'm always excited to find previously unknown of software on this media. If you happen to have anything please feel free to reach out to me via email at info@byteshop.io

@@timothycolegrove4365 No, I don't have anything. Sorry. At the time it was just a (mostly) failed attempt at a new type of floppy and had no historical significance. Wouldn't have been allowed to take anything anyway. Funny you should use the word "honor". It sure wasn't at the time. If asked, I would admit to working on it, but I never volunteered to talk about it. Folks familiar with Twiggy would give you a look.

hello sir. would you know how a hobbyist could come across some of these drive tests codes or anything similar ? also would it be possible now days to enhance the twiggy drives or make them more reliable?

@@solodobo Everything is long gone of course. The test code was written in Apple /// Pascal and run on Apple ///s with special Twiggy test cards. I don't believe there is anything that could be done to make Twiggy drives more reliable as we would have done so at the time. The design was just inherently error prone.

@vmhanlon - Always love hearing from Apple engineers who worked on the original systems (Apple II, III, Lisa, early Mac). On a side note, did you know anyone in the engineering teams who worked on the Apple IIx, Cortland/Gumby projects? Always wondered about any developments on the Apple II side that never made it past the prototype phase, so little is known about the Apple IIsi, Apple IIp or the Mark Twain (other than the few prototypes that leaked several years ago).

Congratulations on your restoration work! In 1983 the Lisa was nothing short of magic, despite the "majestic" speed. My first job at Apple was working the tech support phone line for Lisa customers. There weren't very many customers (partly because the system cost $10,000), so I had plenty of time to learn a lot about the Lisa. I loved it and got to play with the Lisa Development System too. IIRC one of the cool features was that you could take the Lisa completely apart with no tools. Maybe you could do that for a future video?

I'd never seen an actual working Lisa until now. I was working at an Apple dealership in Amarillo when the Lisa project was announced, but my store (or any other stores that I was in contact with) ever got a demo model. All we had were flyers. It's great to see the origin of what would become the Mac interface. I bought one of the first Macs (the Fat Mac 512K) and loved it.

I saw a Lisa in operation in '83, in the home of a college professor of art & industrial design who hired me on for his personal sideline (an exhibition display system). He pretty much defined what would later become the core Apple Computer constituency -- artistic people with more money than good sense.

A coworker of mine recently revealed to me that he was one of the few third-party developers who developed software for the Mac before it was released. They had to use the Lisa as a development machine. His Lisa was originally a Twiggy unit, but Apple shipped them the 3.5" upgrade and he installed it himself.

It's awesome to see a twiggy Lisa running, one of my holy grail machines that I know I'll never own. However, I do have a Lisa 2/5 (upgraded from a twiggy) and a Mac XL so get to play with and demonstrate them whenever I get the chance. When I first saw the Lisa in Apr 83 in the UK I said 'I want one!' Took me 17 years and by pure chance got my first one on holiday in Boston MA. Getting it back to the UK was a chalenge :) Thanks for the demo!

I worked at Bethlehem Steel at the time. Beth. Steel was actually quite progressive on the "IT" front (hard to believe, but true). There was a computer lab where you could work on all kinds of equipment including a Lisa. I guess I spent too much time using it, because when the Mac was announced in 1984, I ended up buying one those early 128K Macs. Yes, they were slow, but the user interface was absolutely revolutionary at the time.

Until I saw this and another video recently, I never realized how profoundly slow these were! I didn't expect 5 MHz to be so much slower than Mac's 8 MHz, but it's clearly an OS difference. Even from a hard drive, it's dramatically slower than Macintosh from a floppy.

Wow, Steve Jobs had his brilliant way of showing how powerful the mouse is: BY REMOVING ANY CURSOR KEYS from the keyboard. I would have hated that. Glad to have switched to the PC-compatible world then. Never looked back. The MAIN kicker for me was that developing Mac software would have required a Lisa 2. What a strange idea.

I just glanced at Wikipedia: A 5 Mhz processor and 1 Meg of RAM. I thought that was a printer sitting on the top at first glance. Jef Raskin might've made something work as he was shooting for under $1,000 but Jobs completely derailed anything that might be viable.

The Lisa OS was, by far, a better design than the original Macintosh system. That's kind of tragic since the template/document metaphor was both innovative and useful. We'd be in a vastly better place had that metaphor taken hold.

Some points: it was a popular form factor for office computers of the time in general. Even when systems used separate monitors they often had the keyboard integrated. For the original Macintosh they wanted it to be compact and even portable. There was an official Mac backpack you could buy to lug your Mac around in.
