at least they're laptops... they don't take up that much space ^^

True 😉 so... I plan to gather only desktop PC units from now on and stash it verticaly to spare some space 🤣

Well... I miss 80/90s ... End of story

15EUR ..... I need to clean it very well now 😉 I have plenty of ISA cards, I wonder if it has any limitations. There is a SCSI controler but I have soundcard with IDE controler so I'll try to test it later. I was supprised about the weight... 27KG!!!

Micropolis of this type will have sticky rubber bumper that arm rest against when shut down (automatic parking) means hard drive will not initialize in this condition. Only way is data recovery on your own by pushing arm away from that gooey rubber and copy the data off. I think this one is MFM.

Second, 286 needs a bootable disk with cmos setting editor to set motherboard's settings to know these parts like floppy type, hard drive type, memory size etc. etc.

Which sticky rubber bumper do You mean because I can't localize any 😉 ok so there's another question, what type of floppy does it has, DD? HD? 720? 1.44? ... Previous owner had no clue as he stopped using it dozens years ago ... thanks for the tips btw.

The hard drive micropolis of this type designed was not smart to use real rubber bumper that voice coil rotary arm hits against when parking during power shut down process. Back in the day (!!), I discovered this when owner wanted me to find out why they don't come alive properly. Arm was too light to unstick from that degraded rubber bumper and cannot be solved by held with both hands and jerked in circular motion incidentally works best for unsticking stuck platters into motion.

Secondly, the sticky bumper was so sticky that arm couldn't pull itself away too.

That was around 92-93 or 97.

Later on, I thought I could fix a lot of Micropolis 3.5" 4GB drives but these screws were all loose due to badly manufactured process meant platters got shifted on their spindle motor. Hard to believe but true.

Weird things happens with this 286, after I've disconnected Floppy drive, HDD started to spin (???) I thought It was ON already.....

Managed to run bios and config something, still the drive is 100+ mb and utility let me choose some other not exactly matched types of HDD (cyl, heads, sectors are different) .... Hard stuff to fight with.
