I suppose it was inevitable, but it's a sad day for #retrocomputing projects needing 5V parallel flash memory in DIP packages.
#DigiKey indicates EOL for these #Microchip parts, with lifetime buy date of 2026-07-01:
SST39SF010A-70-4C-PHE (1 Mibit, 128 Kibyte)
SST39SF020-70-4C-PHE (2 Mibit, 256 Kibyte) SST39SF040-70-4C-PHE (4 Mibit, 512 Kibyte)I haven't checked whether the 3.3V or non-DIP package variants are also EOL.

With Part-DB 2.8 you can now create parts directly from barcodes.
If you order parts from #digikey, #mouser, #lcsc or Amazon, and they don't exist in your database yet, you can just scan the distributor barcode, and Part-DB will fetch all relevant Infos like descriptions, parameters, data sheets, prices, etc. from the distributor, and offer to create a new part based on that.#opensource #electronics #foss #hackerspace #makerspace #engineering

Guía para construir un Amiga 4000T desde cero
John “Chucky” Hertell ha publicado la primera y segunda parte de una guía técnica para construir un Amiga 4000T desde cero, con enfoque totalmente práctico y avisando que no dará soporte a quienes se desvíen del montaje indicado.
La primera parte recomienda empezar por las daughterboards: placa de conectores y Drive I/O (terminación SCSI, disquetera, lógica 74LS) y la placa de Audio/Video (chips de señal como el CXA1263AM y jumpers para audio de CD). Se destaca un punto crítico: los conectores DSUB requieren modificar sus laterales para encajar. También se detalla el cableado, con dos ribbon cables de 40 pines de longitudes exactas: 20 cm (SHORT) y 25 cm (LONG), conectados según etiquetas para evitar daños en chips como Paula o las CIAs.
La segunda parte entra en la motherboard, donde la alimentación con fuente AT exige seguir la regla de “cable negro al centro” para no quemar la placa. Hertell remarca la soldadura de zócalos PLCC como principal fuente de fallos y propone avances por hitos: comprobar sincronismo tras montar chips como LISA/ALICE/FAT GARY, ajustar el jumper del reloj CPU (INT/EXT según CPU/aceleradora) y usar DiagROM para pruebas iniciales. Finalmente se cubren memoria (hasta 16 MB de Fastmem en placa), recomendaciones de terminación SCSI y detalles de Kickstart 40.70.

I can safely say that it's been a while since #DigiKey sold #resistors in pre-packed bags of 5 with included card labels. As their own brand. Made in Taiwan.
Or called themselves "Digi-Key Corporation".
More seriously, I found a bag of #components left over from my senior year of school, when we did our big final project. Mine was a computer-controlled slot machine. Components were seriously expensive then; I organized a group buy with 4 or 5 of my classmates through "Digi-Key", partly because they were cheaper than the local suppliers (see previous story about the "Two Weeks Ten Bucks" guys), but also because we could get quantity price breaks on stuff that was common between our #projects, like the 1 kΩ resistors. IIRC, the resistors cost about $0.30 each in the 5-packs, but the bag of 200 was *way* cheaper - about half that, I think.
These were ordered in 1997, so almost 30 years ago. In addition to #vintage resistors, I found ZTX549 PNP #transistors (still in stock at DigiKey today!), MJE2955T #PNP transistors (also still in stock!), 3 different brands of 741 #opamps, including made-in-Japan and made-in-Malaysia #NEC, TI ones from Taiwan and the Philippines, as well as #TI TL081CP and LM318P from Taiwan. Also a bunch of 74-series logic #chips and some weirder stuff, like a #Motorola MC14412, which is essentially a 0-600 bps (~baud) modem-in-a-chip.
So if you need some vintage components, hit me up 😉

Вы тоже заказываете платы, компоненты и всячину здесь?
Что такое коллективный экспресс (7$/кг) и как его использовать? Почему с 45$/кг бывает дешевле, чем с 23$/кг? Как заказать компоненты/всячину с сайтов JLC (jlcfa, lcsc, jlcpcb, …)? С 1688, Тао бао и других китайских площадок? Привезти из Европы, США (Маузера, Диджикея и т. д.)? Надеюсь, продуманная навигация по статье и таблицы помогут быстро найти и сравнить полезную информацию.

@frameworkcomputer There's a reason there's a Newegg Canada. Also on my wishlist:
• @iFixit Canada
• #Digikey Canada

when designing electronics usually you have a huge choice of what component to choose. see the example URL with 25k models of "switching voltage regulators", then you limit down by your electronic parameters, then by your mechanical parameters (size) and finally maybe by price.
since the recent weeks I also start to filter by company/manufacturer, and I start researching whether a company is american or not, and I learn a lot.
I am certain I am not the only one trying to boycott US products, but it would be interesting to see the real numbers from #mouser , #digikey and others. they have the numbers from the search queries.
oh, and they're US-based. -
So, I searched on DigiKey for real DS18B20s to include on my next order... and what a surprise!
Almost all variants of the Maxim DS18B20 are out of stock (as expected), but they are now selling those chinese clones at almost the same price as the authentic ones! 🤦♂️

Crazy world. That seems to be how the supply chains are working in 2023. 🤪
