Just building your own microprocessor from gates is an easier way to learn about designing microcode and understanding how processors work(ed). But it can't hurt to study a few simple old designs like RISC or Transputer. The 80386 is on the other side of that spectrum, needlessly complicated because they wanted to be backwards compatible with an old bad design.
There certainly is no need to go to university to learn chip design. Watching a few Alan Kay talks [3] or browsing Bitsavers computer designs [4] are good starting points.
We made an easier way (than FPGA) to simulate and convert your gate level design into transistors on a chip (for less than $200 in 2026). We call it Morphle Logic [1].
Eventually you grow into making the largest fastest and cheapest supercomputer wafer scale integration [2].
the kill switch is discussed in part 2 https://youtu.be/za62IvbfzXE?t=1061 by the fire department who got the drone donated by the interviewer from "Protrct Ukraine"
I have informed a few 3D printer operators on how to do it themselves. But it is hard for these soldiers, they have other priorities.
It is not 'standing in their way', it is revealing the secret locations where the Ukranians drones are manufactured. Several of these factories where discovered and Russia bombed them.
1) I have heard of the kill switches being used from several sources in the Ukraine ministry of defense. I advised them on how to remove the kill switches in two brands.
I am an outsider on the details of the Bambu software requiring users to go through their servers in China and the closing of their software.
Still I suspect it is about spying in wartime, Bambu printers are at the core of the Ukrainian war effort, the main reason even Ukraine is winning since januari 2026.
First China prevented Ukraine from using any of the drones that they sold in millions to Russia while exercising the built in kill switches in Chinese drones used in by Ukrainians.
Suddenly Bambu, another Chinese company started listening in on the 3D printing on a massive scale in secret factories all over Ukraine that make the drones to replace the Chinese drones. Very suspicious.
Whatever is the reason Bambu locks down software or firmware on their 3D printers, now is the time for programmers to change the situation. We need to put up money like Louis Rossmann did [1], not to fight legal battles but for a assembly language programmer to reverse engineer the Bambu firmware and make a free and open source version.
This firmware replacement will cost a couple of months to write so we all should send that programmer a little money so he/she can release it for free.
A free Bambu firmware will allow the Ukranians to continue producing another few million drones and save over a hundred thousands lives by ending the war.
Now is the chance for us outsiders to help Ukraine, by freeing Bambu firmware.
P.S. I would be willing to do the reverse engineering but I would need at least 35 euro per day (to eat) to build a new firmware for all Bambu models from scratch. I would need a few different models of printers on loan for a few weeks to test the new firmware. I estimate it would take 5-9 months to rebuild firmware for all models from zero and release it. Maybe Rossmann and Geerling could use their influence and coördinate this freeing of the firmware?
I just emailed Rosmann and Geering to see if we together can free the Bambu firmware. Anyone who wants to help, please contact me trough my HN profile.
Great work! I'll buy one for $250. Will it run AppleTalk?
I didn't correct for inflation but I wanted to buy the Lisa before it was released, it felt around 40000 Dutch guilders, maybe 80 times more expensive than this FPGA?
I did a few more back-of-the-envelope calculations of what I can do with these 2MB SRAMs:
Xerox Alto with Smaltalk-80 and Smalltalk-76 for $4. The Alto was the 1972 machine the Lisa tried to be the sucessor of.
Transputer T414/T800 for $50 but much faster than the original. You would make a supercomputer interconnecting hundreds of Transputers.
Vextrex without display but HDMI output for $50, $8 without the CRT/VGA/Oscilloscope, $100 with the cathode ray tube display built in.
200MB SRAM with 16000 cores 180nm WSI (Wafer Scale Integration) emulating most processors at $1000. It would outperform 2025 Blackwell NVDIA and Apple Silicon M3 Ultra Mac Studio because SRAM is faster than HBM or LPDDR5. It is much cheaper than the 2MB Sram on this Lisa FPGA (it costs around $25 per 2MB (16 Mbit) in batches of 1000 chips).
The research into the origen of life looks at bottom up fundamentals (how they work) of all cells since the solar system was formed. You could start with the slides in this lecture and read the underlying papers and all the references in all those papers. You probably can find these references also in all the books he wrote. https://www.youtube.com/watch?v=vBiIDwBOqQA
Maybe an educational text for the laymen has summarised this recently but I'm not aware of one. Most Biology from your school days have been rewritten.
I will have to re-read Molecular Biology of the Cell, 7th Edition, 2022. I read the 3th edition and it has changed dramatically since.
Thank you Matthew Dugal, but no thanks. You just created a bad GUI of a bloated database as a shaky web server.
I am using a few of your photo's but as a database I just filled a spreadsheet (poor man's database) that I can turn into a website hosted at home with two clicks: Squeak with Seaside, Magritte and Pier CMS (swiki). I then render a catalogue PDF with another few clicks for the LLMs. Total time for setup from zero 82 minutes, mostly the time to search the files on my spotlight indexed 400 TB harddisk.
The Byte magazines are extra searchable documentation for the Retro Computing stuff (from capacitors to fix old CRT monitors, cables to wire up coax, ADB, SCSI, IEEE-488 and Appletalk, whole computers, Transputer supercomputers, IBM Risc 1000, early FPGA's) and ways to do SEO: if people search for Lisa than Byte text OCR-ed will find Macintosh XL and my web page catalogue and they see I have several for sale.
There is a faster way still, just get you stuff in a csv tab delimited list and render it into a html file and host it on my first webserver september 2 1991 [2] or today on one of the few free webhosting options left: https://100yeararchive.neocities.org
When I started the first public ISP in 1987, several years before the first web page (on August 6, 1991 [2]), I just hosted my collectables and magazines (The same as I offer here today, I still have them 49 years later), photo's and hardware on hyper cards, mailing lists, uucp, usenet, FTP or Gopher. Webpages we also hosted on the unix home directory of my customers next to their pop email box. I think of your proposal as: the early internet is a great improvement on its successors.
The short answer if there is any "there" there for photonic computing is no, maybe.
You need to understand quantum physics[3,2]. For example, photonic computing, photonic logic does not have a switch equivalent as semiconducting (CMOS transistor) or superconducting (Josephson Junction JJ) but we have a photonic Mach Zener interferometer (MZI) and a photon detector.
Photonics and superconducting electronics is always going to be much larger in size (and therefore more expensive) than semiconductors build from few atoms.
In quantum physics photonics we have advantages like quantum impedance, you can replace wires with photon transmitters and photodetectors and thus switch with only a few photons instead of large numbers of electrons.
With photonics you can have billions of cheap low power data channels instead of high power wire bundles. But MZI as JJ will probably always be a few orders of magnitude larger than transistors so switching is not going to be better, but interferometry is.
Shorter answer still: just low power communications and information processing yes, computing no.
Bulk CMOS manufacturing is still cheaper than all the alternatives we have discovered or invented, until we learn to manufacture atom by atom or compute with single photons or electrons (also dependent on molecule by molecule self-assembly), we will stay with CMOS and Moore's law.
Just listen to David B. Millers[1] lectures [2], his lectures are a shortcut to reading all his papers[2] that explain it all, especially [3].
Email me, I'll give you a private lecture.
