#retrocomputing folks: I'm trying to get a sense of the proportion of people here who are into retrocomputing today but didn't experience the machines when they first came on the market.

@fluidlogic I worked on PDP 11s from the mid 70s to 1981 then onto Vax gear. So 16bits then 32 bits. It meant I got into 32 bits early and I wasn't interested in the PC machines. I did dabble in Windows towards the end of the 80s because a client wanted it and... only 16 bits? Are you kidding me?
Windows 2.1 and later aren't entirely 16-bit. Apps run in real mode and use 20-bit segmented addressing, but if it's running on a 386 or later then the kernel will run 32-bit and map pages in and out of the 20-bit address space in response to GlobalLock calls.
But you'd have to wait until 1993 to get a Windows in which apps can directly use 32-bit addressing. That's when NT 3.1 and Win32s (a shim to run 32-bit code on regular Windows 3.1) came out.

Did you replace the system board at any point? As far as I know, the 5150 BIOS doesn't know how to boot from a hard drive.
@fluidlogic @argv_minus_one The controller had an option ROM.

You could have upgraded it to a 486. Not a Pentium, though—Pentium motherboards were ATX and needed the case to provide a soft power button.
As far as I know, nothing much changed after that, so you could put modern hardware in a Pentium-era case…although you might need to drill some extra vent holes in it and add some more fans!
No, lots of the early socket 5 pentium motherboards were plain-AT, it wasn't until the later ones, with socket 7 and SDRAM, that they started adopting ATX. Mostly because it meant they could get 3.3v directly from the psu instead of needing a regulator on the mobo.
I had a gateway 2000 100mhz pentium with a big clonky power button and big hot 3.3v regulators on the motherboard.

@quinn it's more of a mix than I expected!
@fluidlogic @quinn maybe more of a mix than you might guess.
I'm not active in any "retro" sense, but I did work for an 8-bit maker in the 1980s - as well as having the same gear personally.
Which means I don't have a rosy nostalgia and instead remember how flaky the hardware was, how scant the documentation was, how few were our ways to get answers - etc.
But what I am grateful for in retrospect, is how understandable those systems were. So much of what I learned then, still guides me.

#retrocomputing folks: I'm trying to get a sense of the proportion of people here who are into retrocomputing today but didn't experience the machines when they first came on the market. I want everyone's input! Please boost!
(I'll ask the same question about minicomputers. This poll is about the early consumer home computers released between say 1977 and 1994.)
@fluidlogic I could only dream of 16 bit processors

@lackthereof @argv_minus_one @silvermoon82 Also there were Pentium Overdrive chips that naturally fit in pre-ATX boards.

@rogerparkinson did you skip the 8-bitters entirely?
You're a candidate for the minicomputer poll!

I don't think you could buy any 8- or 16-bit computers in 1994. That was well into the 32-bit era.
The beginning of the end of the 16-bit era was 1986. That's when the 386 came out. It was obsolete in 1989, so that's when I'd say the 32-bit era had begun in earnest.
@argv_minus_one yes, they overlapped. In 1992, Atari released the Falcon and Commodore released the Amiga 4000.

@fluidlogic there's a lot of room to carve this up. Like CP/M was mostly before my time but I got pretty into those machines when they were at once relatively almost new, but also very obsolete- and I'd argue that was retrocomputing. Similar for the TRS/80 model 2/16/6000 which could also run XENIX and verged on being minis.
@wotsac yes "heyday" is shorthand for "the time during which a machine felt new and exciting and was productive".
This is not remotely a scientific poll! I have no idea if people who are answering are really current retrocomputing aficionados, for example.

@fluidlogic I did skip them entirely, yes. Though I have done things with embedded 8 bit devices more recently eg ATTiny85 and Teensy.

@rogerparkinson did you consider them mere toys at the time?

You could definitely buy major name consumer grade 286 desktop PCs in 1990.
My dad replaced our family's z80-based Heathkit with a 286-based Packard Bell on or around that year.
A lot of people just didn't use Windows back then, and the extra cost of a 386 had little advantage if you weren't doing gui+multitasking.
It wasn't the 386 that ushered in the end of 16 bit computing, it was windows 3.1... which could run on a 286 but was painfully restricted there.

@AdrianRiskin thank you for sharing that story. The PET is probably repairable for not much money!
@fluidlogic really? Fixing it probably isn't for me, but I would like to give it to someone who could fix and enjoy it (and pick it up in Los Angeles bc it's unreasonably heavy). Do you happen to know how I could find folks who might be interested?

@AdrianRiskin yes! Put the word out on here, using the tags #retrocomputing , #vintagecomputing , #commodorepet and optionally #losangeles and you'll get people popping up offering to take it off your hands. If you can include a snap or two, so much the better. Good luck!
I suggest not putting power into it, as the chemistry-based electronics will have degraded in storage and might pop, making repair harder.

@fluidlogic Editing a post with a poll resets any votes already cast on that poll. (it's the way Mastodon works)
Everyone who voted before will have to do so again if they want.
