Okay so I dont know if any of you will remember me but I was the guy having doubts about picking this 286 AST computer a while back in the retro computer thread and now have some time and here it is and is a beast of a machine, just the size of it makes me thinks it was meant for industrial use
Vintage computer thread !

Pretty badass
Gonna put it up your butt?
Nice
post guts
the size of it scares me
...
>just the size of it makes me thinks it was meant for industrial use
Fairly sure that was pretty much the standard size back then. I had a desktop 8086-based computer from Mitac that was about the same size.
Is the keyswtich also the only powerswitch?
noice
what's the manufacturer of the hard drive? the front panel design looks enterprise(TM)
there is a main power switch back on the power supply, but yes turning it on is with the keys
its a Fujitsu limited edition from 1986 40mb and is operational
forgot picture
and this is its RAM
>tfw I knew it deep down
I wonder how the '80s 5.25'' models compare to the shit they made in the '90s, their 3.5'' stuff was slower than shit
pretty cool box though, keep that shit safe and going, don't forget to go over to winworld and see if there's anything cool to run on it too
what was it again, like a 286-16?
i dont know all I know is that is a 286 anything in more detail dont know
well I mostly picked it up cause I was interested in the CGA/EGA 14" monitor that camed with it cause these are RARE as fuck at-least here In Europe
The two right-most connectors are the ordinary ISA connectors, right? Any clue what the left-most connector is?
Shit, were RAM controllers still rocking inductive delay lines in 1988? With those huge QFP packages on the motherboard and all, I'd have thought they had moved beyond that since long. Was this some kind of budget build?
dont know it plugs in the motherboard so maybe a advanced ISA slot, IBM model 80 has them to
Its vesa local bus.
For anyone who's interested, here's the datasheet for those memory chips:
pdf1.alldatasheet.com
tRC is 175 ns, tRCD is ~50 ns. It's pretty amazing how RAM latency hasn't even improved by an order of magnitude in 30 years.
It is most certainly not. The VLB connector pad pitch was much higher.
And by higher I mean lower, of course.
Lots of boards had those extra connectors for RAM expansion cards, always wondered what they actually looked like though.
>Was this some kind of budget build?
It was probably a pretty decently mid-range system especially with that huge hard drive. 286en weren't budget-tier until around 1990.
With early PCs the easiest way to tell whether or not you're looking at budget shit other than going off of the date codes themselves is the level of integration and size of the board, the very last 286 boards had 1-chip chipsets, maybe a ROM and two to four smaller DIP chips. Opposite goes for high-end shit like pic related where pretty much everything is implemented in discrete 74xx series logic or custom ASICs
take a picture of the CPU desu, probably the little Intel i-logo'd socketed chip below all of the labeled BIOS ROMs
sanic ram
