Still cant believe whats inside the box I received today...in fact one of the best lots I have bought up to date! Around 10 kg and nothing in this box I would not like to keep. Even more surprised as there were more items inside than shown on sellers photos. I.e. I didnt expect that Suntac board. …

Working condition. I havn't checked built-in FDD and HDD controller (they fail sometimes on the boards). Small battery leak to neutralize (in a few months it would be a catastrophe though). Paid under 10 USD (in Polish money). It's second SUNTAC-286P in my collection. On the first picture a …

that thing is really neat, it seems it supports SIPP modules, sadly i don't know anything of the 286 era Nope, it's definitely not NEAT . OK ;) this joke was a bit niche... That joke was OA.K. AM.I aware of that? Yes, but it was on the VIRGE of being funny (in fact it was A.BIT dry) so I don't …

ZyMOS Poach VGA/EGA - pretty neat! Never seen a card of this brand before. It seems it's some sort of Trident Clone. Yeah, apparently it's a rebadge of the Trident 8800CS, maybe only the third or fourth VGA product out of that company. Btw you may want to cover up the window on that upper ROM ASAP, …

So I bought this 'dumpster' PC today. Seller and auction pics state it's in working condition. Payed ~55$. 286 (don't know which one yet), 2 SIPP modules, Tseng ET4000, Seagate ST157A with black front panel... I will call it "zie gehrman condom" because of the sticker and the country of origin… …

So I made some more tests today, and it seems it's not fully fixed yet. The problem is CPU gets really hot (almost too hot to touch it). So it works well for a while, boots DOS, runs programs for a while and when it gets too hot it just hangs. Even keyboard won't react. When I reset it or turn off …

286s were nothing unusual in Europe (especially in Central/Eastern Europe where I live) until mid-90s. All my 286 mobos so far are from 90-91 and all come with SIPP connectors. I have a bunch of fresh NiCd's so yeah, I will replace it ASAP. Here is another motherboard that arrived in mail today ( …

You got yourself a piece of history there, so treat it like one. Now you are not just a computer geek. Now you are a custodian of a technical monument. While sometimes caps or resistors are intentionally omitted by factory even when there is a place for them on the motherboard (for cost reduction …

There are many interesting 486 CPUs. There are 486 CPUs faster than pentiums for example AMD 5x86 - but those will require good motherboards to run. Generally - a rule of thumb is to stay away from boring as hell intel stuff and you will find that every platform has it's unique feel.

What are the benefits of a 386sx-40 vs, 386dx-40 ? Besides the obvious that the DX has a math-co processor This is one of those misconceptions that will never die. As people have pointed out before, the difference is not FPU-related. SX means S ingle word e x ternal, or having a 16-bit data bus; DX …

That is awesome. Did you end up trying the original keyboard controller in the replacement socket? In case it was a bad solder connection vs a bad chip? Edit: now it is running, can you do a checkit 3.0 score on it, want to compare with how mine runs. Yes, I tried original KBC in the socket and it …

So I fixed it. I desoldered the KBC (which wasn't that easy - I had to use the pump and braid several times on each row of pins), I soldered a new DIP40 socket, installed the KBC from another HT12 motherboard (pretty much dead one). And voila! :D https://youtu.be/w33fLORxsWg Behold my sloppy …

I bought some proper soldering (or rather - de-soldering) supplies... I'm going to desolder the KBC and solder a DIP40 socket in it's place. Same with the HM6818P chip next to it.

Does anybody know what is the difference between those two 286 chipsets? Advantages/disadvantages of one over the other and so on... I see a lot of mainboards with HT12/A and less with HT101A/102 duo. I guess HT12/A is more recent as it's integrated in a single chip? Motherboard with the HT101/102 …
