I always remember PCMCIA as "People Can't Memorize Computer Industry Acronyms".
It's a bit of a shame that ExpressCard never got traction. I've had mixed success with USB Ethernet compared to the old PC-Card Ethernet.
The fun days of using the ExpressCard slot to play AAA titles on a beat up Thinkpad or back when EVDO was the new hotness in mobile productivity..

To be fair they did change the name of the standard to PC Card - people just kept using the old name anyways.
PCMCIA was an ISA bus on a card. PC-Card was PCI on a card. Then came Express Card, and no prize for guessing what the bus used there was.
Express Card made the mistake of offering multiple form factors which made it harder for laptop manufacturers to support.

This may change thanks to USB 4 (and Thunderbolt) being able to directly use PCIe lanes.
holy goodness I have not even thought about PCMCIA for like ~30 years!!
Reading this is pretty funny to me because my first wireless router was a common one with a PCMCIA slot to connect a WiFi card :-)
MacBookPro G3 with PCMIA slot, an Orinoco Gold card, a Pringles can made into a Yagi style antenna, and a friend with a car for wardriving sessions. memory lane...
I was thinking what was the gold card and kept thinking of cryix cpu's, but it was Orinoco! Those were worth their weight in gold and hard to find compared to linksys pcmicia.
And then having to do some ndis wrapper fun with linksys or intel cards. Wow.
And even then, no packet injection!
we used to play around with them pre 802.11 as WaveLAN for under the radar point-to-point links back when the max 2Mbps was eye popping fast and eye popping expensive lol
this is the best sentence I have read on HN in a long time
The C-M0 and by FAR. A 486 would be lucky to hit 0.4 instructions per cycle on a good day with much luck. C-M0 can maintain a IPC of 0.8 for most code (loads and stores are 2 cy, all alu stuffs are one).
486 ALU stuff is mostly 1 cycles as well (other than shifts, MUL and DIV, and all the weird stuff like AAD), as well as stores and loads. Taken conditional jumps are 3 cycles, non-taken 1 cycle, so loop unrolling helps a lot on 486.
You can approach 0.8 IPC on 486, assuming you know about AGI stalls and other quirks.
General 486-era C-compiler produced code, though, would be lucky to hit 0.4 IPC.
I was taking intel's 80486 promo materials at face value. Plus 486 ALU may be 1-cycle but loads and stores are not 2-cycle like they are for C-M0 so it'll still lose :)
Most of these small ARM micros are an external memory interface and a good OS away from being a mid-90's workstation. The larger ones (high-end Cortex-Ms) are probably comparable to Powermacs of the early 2000's.
Heh, it reminds me of this gem: https://www.youtube.com/watch?v=ar9WRwCiSr0 which does something similar... using a modern device to give old devices essentially capabilities beyond what they should be able to do.
the 1541 disk drive that you would pair with a Commodore 64. It had a 6502 CPU in it, and was clocked a little faster than the 6510 CPU in the C64 itself.
The Apple LaserWriter'ss 68k cpu was clocked at 12Mhz, intended to be used with Macs having a 68k CPU clocked around 7.8Mhz.
5-10 years ago I was worried about a cliff for 80's car chips. Turns out, we can buy cheap programmable boards and write our own "native" solutions.
My current project is mapping out 80's HELLA cruise control units. They have just a few inputs and variables. Speed, brake signal, pump, clutch signal, and on mine, an additional signal to the APC to show it is engaged (to limit boost). Really, I think I'll be able to make this work - hopefully smoothly!
EDIT: these were in Saabs, but also other manufacturers like Land Cruiser and I think BMW as well. HELLA sold these as OES for these vehicles.
ha same! but for game cartridges. I was worried that dumpers would be impossible to find, nowadays I could just build one if I really needed it.
That's super fucking rad... though I assume there's a hardware override? There are a few hundred open issues on the firmware repo.
for t5 suite? It's pretty stable. Not sure what repo you're talking about but essentially they have backwards engineered the ROM on the ECU's to make tweaks and adjustments. It's a very flexible system from what I understand (though I haven't tuned with it at all, I do have one car where the computer is from a 2001 and it's backported into an 80's saab)
> The bigger deal for me would be this old laptop and card speaking WEP rather than WPA3.
As I understood, this is exactly helping with not having to use WEP. The Pico is simulating a NE2000 ethernet card, so any old pre-WPA Windows98 drivers are not used at all, but with the Pico doing ethernet-to-wifi conversion and WPA2 encryption.
I have an SDIO 802.11b wifi card for one of my PDA's. SD card formfactor.
It's interesting that SDIO has survived to this day as an interface. Just mostly staying on the same board between some SoC and peripherals.
According to the article, the author is using the RP2040's PIO peripheral, which has access to both the GPIO pins and FIFO buffers for communication with the main CPU.
The PIO is magic adjacent given the unit cost. A relative of mine is using it to bit-bang a proprietary ethernet-like protocol to fix some expensive-to-replace surveillance camera networks. He's a 10x (at least) engineer and he's impressed by the capabilities. "And then it's just some C-code, which is of course trivial."
pcmcia is an ISA like bus. You can just bitbang ISA with pico
