I have a Atari Inc 800XL (1983) and an 800 (1979) downstairs that still work great. And an Atari Corp 130XE (1985?) with dead DRAM that doesn't, despite being newer and in much better visual condition. Apparently a very common failure. The XEs were a "rock bottom pricing" innovation from the Tramiels, after creating Atari Corp from some of the ashes of Atari Inc. Cheaper components and my impression is they are not of the same quality.

But I was an Atari ST user back in the 80s, so the case design has some nostalgia value to me.

I was an Atari ST 1200 user too. In college, I told no one. I felt like I was cheating with the word processor. The other students would talk about paying someone $1.00 a page for typing, and I said nothing.

I told my college girlfriend she could use it whenever she wanted, but she just didn't like the poor Atari. I remember trying to get her interested in the drawing program, but still nothing.

I still have a nice memory of me demonstrating the abilities of the drawing program though. I was fooling around and drew male and female anatomy on the screen. She said, “You’re getting me horny. Turn that box off!” I was astonished on a few levels. I never heard her say anything remotely sexual, and I like it. I remember breaking up with her after we graduated, and I never found anyone even close to her on a lot of levels. I mistakenly thought the grass was greener.

I had this irrational fear one teacher might question the dot matrix print, but no one questioned anything.

My girlfriend at the time thought I was crazy for spending so much money on a computer.

I hated writing papers, but the computer saved me a lot of hassles.

I wish now I explored other aspects of computing back then, but in all honestly, I felt like sitting in front of a screen for anything other than writing, or making money, was waste of my 20’s.

I even got to the point where I didn’t like computers. I still have a love hate relationship with a lot of tech.

I remember looking at the case, and the monitor a few years after graduation, and tossing it all away. At the time, I wished they didn’t use that beige for the case/monitor though.

Now—-I wish I kept it. That word processor was everything I needed to write.

"What you have to realize," said one Atari engineer (I think it was Shiraz Shivji), "Is that DRAMs are really analog components."

IIRC the ST was running DRAMs a few tens of nanoseconds (ten to fifteen percent) faster than they were rated. Not sure exactly why, but I think the ST was running cheap parts faster than they were supposed to go, and it largely got away with it.

Wonder if they played the same games with the refreshed 6502-based systems.

They did that so that they could run the Shifter from the memory on the off-cycle of the CPU, right? I mean, it's crazy because it worked and all my STs I have downstairs have never failed, and I don't recall ever having issues with memory chips on them, and I don't recall them ever being unreliable.

As for the XE, from reading the forums it sounds like they just used a bad batch of 4164 DRAMs, something to do with them being American made and not Japanese. I seem to remember this was the era of crazy fluctations in memory prices.

Oh yeah, in 1986 Reagan administration introduced tariffs for 64K DRAMs from Japan. I remember having a bunch of trouble tracking the chips down so I could upgrade a 128K Macintosh to a 512K "Fat Mac" (which was easy to do, if you had one of the oddball new Torx bits -- also hard to find -- and a soldering iron stalwart enough to defeat the massive and heatsink-like ground plane on the Mac motherboard).

512K for about $240, IIRC. My first major purchase at Fry's, which had recently bifurcated a supermarket into a "chips" side (with dip) and a "chips" side (with sockets).
