There are some fancy K9s out there man.

But is your wallet ready?

1MB RAM, no HDD and dual floppies in a Commodore Amiga 2000, with an additional 5.25" floppy drive hooked up to a PC emulator (which I never got working, unfortunately).

 

Ah, those were the days.  Ironically, my second computer (an AMD 486 DX/2 66MHz) had a 500MB HDD, but only 640KB of RAM.  Yes, a single stick of 640KB EDO SIMM RAM.

Oh, my actual first home PC running windows 3.1 when I was 12... yeah, probably that. I forget it was that long ago.

Was there such a thing as 640k ram sticks in those days? I really can't remember but find it hard to get something not power of 2 in capacity. My system of that era was an Intel 486 DX/2 66, 250GB MB HD, and I started with 4GB 4MB of ram, later updating it to 8MB. Gotta watch those GB and MB for that era! I remember the 4MB was in 4x1MB sticks, and to go to 8MB I got another 4 sticks. I didn't have 8 channel ram, but I did have 8 sticks!

 

For young un's 640KB was the conventional memory limit that could be accessed in DOS mode. If you had 1MB of ram, you could still use the area above 640k, think it was called high memory area. And there were different ways to access the ram above 1MB. Hmm... given how "backwardly compatible" modern systems are, I wonder if there still is a 640k region somewhere reserved as conventional ram.

Ours had memory chips you inserted directly in to the main board, upgraded from 1MB to 4MB which was extremely expensive at the time. After that there was something before 30 pin SIMM but for the life of me can't remember it's name or find it. Was like 8 - 12 semi long pins, old as hell.

 

edit:

Found it 30 pin SIPP

were you supposed to solder those?

That's Fast Page Mode RAM .. was before EDO RAM, which was before SDRAM

Slots were at an angle, like some SO-DIMM slots are (pic from Wikipedia):

 

Was "fun", you had to install them in pairs or sets of 4 to match the processor's bus width.. not the same as we do these days with dual channel or quad channel ... today each stick is 64bit wide, which matches the bus width.

I remember double and triple checking, the system only showed 640KB installed.  I got it as a full kit, just not assembled.  It's possible that it was 1MB and it merely showed up wrong, but all I can say is that it definitely only showed up as 640KB.

I spend so much time playing TES2: Daggerfall back in the day, and mouse movement made a huge difference from using just the keyboard, though I can't recall now if that was in DOS or WFW 3.11 I played it in.

Good memory, I had forgot about Fast Page Mode RAM.  Now that I think about it, I'm pretty sure that's what was in my 486.  Then again, the last time I messed with it was nearly a 1/4 century ago.

 

Ugh, that makes me feel old.

side quest: AMD announces their answer to Intel's HPC and Finance-oriented CPUs (9990XE? W-3175?)

the EPYC 7H12

I'm sure they'll have many uses, but doesn't look like it is a HFT targeted CPU (like 9990XE), way too slow even factoring in IPC, unless the cache does something magic in that application. Also from article:

AMD states they have other processors better suited to certain other fields, such as finance.

it's 280w because of 2.6ghz base freq on all 64 cores.

The 64 core 2.2 ghz is 225w tdp.
