(before being split, this means there were over 216,000 parts that we had to sort through manually!)

these parts started out at HSC Electronics (aka Halted) in Santa Clara and were collected over a period of 40 years.

HSC was on Ryder street for many, many years, but they had to move in ~2016. the building was demolished in May 2017.

HSC/Halted has had several other locations over the years, but served as a steady source of parts for hobbyists and engineers. many famous individuals bought things here.

unfortunately, the company had to shut down their retail outlet in 2019.

most of their inventory got sold to Excess Solutions (located in San Jose).

this was great for a while, but on July 16, 2022, Excess Solutions opened their doors to the public for the last time. and on that day, I decided to get myself a guaranteed supply of chips, and two of my friends were totally down for it.

we ended moving 80 cabinets -- containing 4,000 plastic drawers, to an undisclosed location where we could slowly pick through the collection, catalog it, and separate it out three ways.

a long line of metal cabinets with countless plastic drawers, each labeled with a part number.

after separating out my share of the parts, i stuffed them into thousands of plastic ESD-safe bags, each labeled with a sharpie and stored in a moving box.

over the last few months, i spent hours and hours carefully packing chips into separate drawers. by putting multiple part numbers into a single drawer, i was able to reduce it down to just 12 cabinets.

if you've been wondering why i haven't been posting as prolifically this year, this is the major reason.

Tube❄️Time replied to Tube❄️Time

OK some answers to questions you might have:

* i don't want to run an electronics business so i'm not planning to sell any. doesn't mean i won't give parts to friends occasionally.

* yes, i have a catalog of parts organized in a spreadsheet, which makes it much easier to find things

Tube❄️Time replied to Tube❄️Time

* yes, many of the drawers (for MOS parts) have ESD protection in the form of an aluminum foil layer. i applied it with glue and this custom 3D-printed jig.

3d-printed "die" that helped me form-fit foil into the bottom of many of the plastic bins.
Tube❄️Time replied to Tube❄️Time

HSC originally used black ESD foam which degraded horribly over the years. i hate that stuff. i hate the sour smell it gets when it degrades, and i hated having to pick hundreds of chips out of crumbling, decaying foam.

Tube❄️Time replied to Tube❄️Time

* rarest part i found? probably these 4004 processor chips. but there were other oddities in the collection, shift register memories, drivers, and that sort of thing.

@tubetime how many parts succumbed to the black foam curse

[DATA EXPUNGED]
Tube❄️Time replied to DELETED

@carpetbomberz yeah they're neat but were state of the art for only a short time so nobody remembers them

Inari :acefox: replied to Tube❄️Time

@tubetime I bet there’s a bunch of nerds losing their shit over this right now.

Miles Goodhew replied to Tube❄️Time

@tubetime Holy heck! I've never seen so many 4004's!

Eric S. Pumpkins replied to Tube❄️Time

@tubetime This is amazing. I had been hoping someone that would take care of them got all the good stuff :)

Dan KB6NU replied to Tube❄️Time

@tubetime Now you can get into the calculator business. :)

Rue Mohr replied to Tube❄️Time

@tubetime Could I apply for some 1 bit SRAM with separate Din and Dout lines?

Tube❄️Time replied to Rue

@RueNahcMohr like a 2102 or something? those are still pretty common iirc

Rue Mohr replied to Tube❄️Time

@tubetime I dont know, I always wanted to make a digital delay out of one, could never find one of the static ram chips with separate IO lines.

Tube❄️Time replied to Rue

@RueNahcMohr a shift register memory would work better for that

Tube❄️Time replied to Tube❄️Time

funny story, i loaned some parts in the 4000 series (support chips) to a friend of mine who ended up building a SUPER COOL PROJECT with them. like -- mind blowingly cool. keep an eye out for 4004-related news.

@tubetime
You're giving me flashbacks -- I built a lot of stuff out of 74LS about 40 years ago.

I know you didn't ask, but I am not crazy about aluminum foil for ESD protection. You don't want high conductivity, you want low (but non-zero) conductivity. That's what the black foam was doing, before it died of old age.

Foone🏳️‍⚧️ replied to Tube❄️Time

@tubetime did you find any chips damaged by that foam? I've heard it's slightly acidic so it can damage them over the long term

Tube❄️Time replied to Foone🏳️‍⚧️

@foone oh yeah plenty of chips with their legs rusted off

Hobson Lane replied to Tube❄️Time

@tubetime
Is foil a good idea? I thought ESD pads and plastic had some resistance?

Tube❄️Time replied to Hobson

@hobs it keeps all the pins shorted to each other.

Jen Costillo :verified: replied to Tube❄️Time

@tubetime happy they didn’t just get trashed.

To me HSC and the like were the last vestiges of the Silicon Valley that I remember. Where else could I go over lunch with a friend and have random guessing discussions about what this or that machine does?

Tube❄️Time replied to Jen Costillo :verified:

@RebelbotJen yes! the guy was going to toss all the parts and sell the cabinets.

Ian Hanschen replied to Tube❄️Time

@tubetime I really want to know what you have - I don't have a good reason for it, just curious.

Tube❄️Time replied to jamespthomas

@jamespthomas oddly, no. most of the fun obvious stuff was already picked by the time i got it.

SLCW💥 replied to Tube❄️Time

@tubetime I hope you've got a few projects lined up for all these chips.

Eli the Bearded

@tubetime

I have long wondered about your stock of old chips. This explains so much.

D. Creemer

@tubetime @Cdespinosa is there anyplace left? WeirdStuff, Halted/HSC, Excess Solutions, Disk Drive Depot, Fry’s???

Mark Pauley

@tubetime I spent a lot of time in that building…

Dan KB6NU

@tubetime I fondly remember trips to Halted and Haltek when I lived in Sunnyvale many moons ago.

Khalamov

@tubetime I remember going to HSC all the time when I lived in San Jose. I left the Bay area in 2012, then read about HSC closing online. I didn't know the building had been torn down. :(

aardvark

@tubetime wow, you bought out HSC's collection? Epic!
