New Old Stock 286 Mainboard at 20MHz, Battery Repair, Testing and Gaming

[@CPUGalaxy]

If you want to buy this board as well you can get it on ebay. The seller comes from Italy and his ebay name is: CARCOSTA6110 Right now he has no mobo on ebay listed but you can ask for one. www.ebay.com/usr/carcosta1610

[@pawe3554]

I think damage from battery was not so severe because of lack of air circulation. Atleast in some part.

[@DxDeksor]

Thanks ! I managed to get one. However I haven't been so lucky for the battery leakage. The battery clearly leaked over the motherboard but thankfully nothing got damaged yet. Some parts weren't shiny and the keyboard connector had started to turn green just a little. I waited for this weekend to clean it properly. Now it's nice and shiny again like yours !

Just a bit of knowledge, the 20Mhz 80286 was never released to the general public while the 80286 was the top of the line. It wasn’t released until the 80486 was released. 12Mhz was the actual cap of the series. 16Mhz was a theoretical limit with the reference hardware. I used to have a 12Mhz Intel 80286 that I had to overclock to 20Mhz.

Awesome! That BIOS was clearly for 386SX as well due to the caching options. A 286 can’t do any of that caching stuff. (Chipset will certainly support both types of chips) Try turning up the bus speed from Low and you’ll certainly get even better video speed as well. I would swap the crystal for a 50mhz part and try for 25mhz! (Or even faster)

It seems like almost all of the 20 and 25 MHz 286s ended up in Europe. You hardly ever see them in North America. I think because we were quicker to adopt Windows 3.x, which really needs at least a 386 to run well.

[@TheRetroRaven]

Thank you so much for this journey back in time. While my first PC was a clone of an XT , it wasn't really until we upgraded to a 286-20 (with EGA monitor) that I really was old enough to use a PC on my own. The 286 quickly found it's way into my room, instead of being placed under our staircase. I was only 7-8 years old at the time, so this was back in '91 / '92 , when I was in 1st and 2nd grade. I would come home from school and immedaitely after doing my homework, I'd be sitting in front of the machine and playing games (and learning BASIC also). I really hope some day, to find an EGA monitor in working condition, so I can then begin to buy and "re-build" my childhood 286.

[@CPUGalaxy]

yeah man. I can understand you nicely. I also had to find my childhood computer again. I had a 286 as well. I loved this machine. 😍

[@mlodzin90]

Great! I have board with Harris 286 25Mhz :) I hasn't powered it up since couple years, but I remenber it is really fast for 286, even faster than 386SX/16.

[@bundesautobahn7]

I'd personally prefer a 16 MHz AMD 286. To me, that is the sweetspot for a 286. But a 20+ MHz 286 is still a very powerful processor, and considering the year 1992 of that mobo, possibly an affordable alternative to a 386.

Harris 25 Mhz, RULES in retro world!

[@Kedvespatikus]

Actually, a 286 is faster on the same clockspeed, than the 386SX. Not by much, just an edge, but consistently.

[@SeanBZA]

Battery not leaking is because it was never charged other than the residual charge and the tint boost during the 5 minute factory testing. so it never built up pressure inside from recombination. Only the slow degradation of the seals with time that let the KOH electrolyte out.

[@JorgeCarvalho_web_dev]

Hi Sir, +1 for your remark. IMHO I would never replaced that batt. for the one used. I would go to an CR2032 PCB holder solution. Just to be on the safe side

[@Shamino0]

@@JorgeCarvalho_web_dev I wouldn't do that either. I would have used the header connector next to the battery to attach a standard battery holder (2, 3 or 4 AA batteries, depending on the voltage required by the board).

[@Crazy80ivan]

You should have a look at the "bus speed selection" in the bios. It could be that the ISA bus runs at 8.33Mhz now, when set to low. You can use a scope to check if it does anything to the frequency of the ISA bus. Or that it is some kind of wait state between the bus and the chipset.

[@CPUGalaxy]

thanks for the hint. Yeah, this board will be for sure again topic of a video. 😉

[@mlodzin90]

Yeah, I also noticed that option! Could be interesting to try change it ;)

[@wishusknight3009]

Chances are the bus speed on this one is 1/2 clock on the slow setting. And would be 1/1 on fast. This is how most 286 were designed once the ISA bus was decoupled from the processor bus and ram after they started getting too fast for many isa cards. ~12mhz or so.

Harris made the 80286 as fast as 25mhz. AMD up to 16mhz, and Intel to 12.5mhz. But note that the Harris version was a CMOS part, which might not work on all motherboards. Look for a copy of Mark Williams Coherent OS, this was a UNIX like operating system for the 80286. You should be able to compile many Linux programs for it from source.

That is an awesome board and I'm very pleased you were able to save it from impending battery leakage!

It wasn't too long after that when I got my 486DX2 66mhz based PC which ran Doom beautifully. That 486 PC also had an onboard Headland Technologies video card in it. I'm pretty sure that company was sold or went out of business sometime around 1993.

[@GeckonCZ]

The original Pentium was released in 1993. But yeah, '92 is pretty late for a 286 mobo.

[@McTroyd]

In 1992 our sole house computer was an IBM 286 running at 12 MHz. What you've built here is indeed a rocket, especially compared to that machine. Ours had PC-DOS running in ROM, so it started instantly and "felt" fast, but it would never have made those benchmark numbers. 👍

[@siliconinsect]

Ours was an original 5170 AT at 6mhz. A friend had an XT clone that felt faster.

[@McTroyd]

@@siliconinsect Ours is a model that didn't do well for IBM -- the PS/1. I (still) have the very first model, 2011. It was the first "IBM Compatible" I'd ever seen that came out-of-box with a GUI (running out of ROM with PC-DOS). In terms of the office work it was designed to do, it still does it pretty well, just obviously too old to get online. It was the workhorse in the house from 1990-1996, when Pentium-class machines finally came below $1,000 in price.

[@HighTreason610]

A very nice motherboard indeed. The Headland chipset seems quite sophisticated, too, at least compared with older 286 platforms. It almost makes you wonder just how many chipsets were available for the 286, as it seems to have had a much wider variety than the 386 and 486 did. In any case, it sure is a fine example of integration improving over time, from the original full size 5170 boards that were still mostly comprised of glue logic to these tiny late boards that are almost a single chip. Good luck with the overclocking. I actually have a similar board, from about the same time, albeit only 16MHz, with integrated I/O and onboard VGA. Maybe it should get a video some day.

Nickel metal hydride batteries can leak and corrode as well, i see a lot of battery damage from them in mid 90s Toshiba laptops. Green corrosion wicks along the wires.

[@ruben_balea]

It seems that Golden Power (if GP means that) NiCD batteries were actually very reliable, I've Golden Power Sub-C size NiCD battery packs from 1998 still performing like new in emergency lights, so far only some D size Saft battery packs from the mid 80s outlasted those, all others brands failed between 5 and 15 years.

[@SeanBZA]

GP made good cells at a low cost. But that survived because it only had a residual charge from manufacture, and about 5 minutes on the production line during testing. Thus never built up pressure inside, from having to do recombination when fully charged. Saved the seals, and they then slowly degraded with time. Strip the sleeve off and you will probably find all three negative seals have slight leakage, and the middle cell is black.

[@CPU-Z]

Nice review ! there is an empty XTAL socket close to the FPU. I guess the FPU runs by default at the CPU clock speed, and by using a second XTAL (and most likely a jumper) it may be possible to run the FPU asynchronously. That may be useful if you plan to run at 25 or 30, not a lot of 287s can support those frequencies.

[@wishusknight3009]

the FPU runs 2/3 clock on all 286's when coupled to cpu clk. Unless the external clock crystal is populated of course.

[@ccanaves]

@@wishusknight3009 Those were the earlier ones. Some modern 287 FPUs have an internal 3/2 multiplier to cancel the 2/3, so they run in sync with the CPU. The 287XL has a pin that can enable or disable this feature, and I think all Cyrix ones do it by default.

Anyway, what a wonderful board and what amazing information--thank you for sharing this Peter!

[@teknoman117]

It really just goes to show that the thing holding back these older machines was the available memory bandwidth. Both the 286 and 386SX had identical bus performance at the same clock speed (4 clock cycles / 2 processor cycles per 16-bit word). I have a couple of industrial 386 boards that use a 386EX-25 necked down to an 8-bit bus and my Harris 25 MHz 286 runs circles around them. Only advantage the 386 has is software support and that 32x32 bit multiply is way faster.

[@enilenis]

My first PC was a 286, and it was possibly a 20MHz, because it went head to head with a friend's 386... or maybe an extra fast 16MHz with an FPU. Maybe my friend didn't have an FPU. Back then didn't understand internals and don't remember exactly what specs I had. To me a computer was voodoo magic in a box. That hard drive sounds very scratchy. I had a 200MB drive - that I remember and it was more quiet than that. The speed of a dual speed CD-ROM off an HD though. That's retro! Back when you launched program and went to make coffee and it still wouldn't be done loading in time for your return. Hehe. And I just had to edit my comment, because I said 55.3 in 3Dbench couldn't be right and it felt more like a 5. Then I saw the end and realized you got 7 in the retest. That's close enough. 55 would be a fast 486 with VLB video. No way to get that score on a 286.

[@CPU-Z]

Finally I could make that mainboard run at 25MHz, by changing the main crystal to a 50 MHz version. But to be honest, it is not 100% stable configured in 0WS (even with the excellent 60 nm Topless memory). In 1WS it is stable, butnot much faster than @20MHz/0WS. I don't know if using a real Harris 25 would improve stability ... So anyway a very good mainboard, I'm glad to have bought it after your test !

[@necro_ware]

As always thumbs up, Peter! A very nice mainboard, I'm also keen to get my hands on a Harris 20 or better 25, but they are rare meanwhile. Interesting point with the NiMH batteries.

Install a socket for both CPU and NPU crystal since an NPU is usually less tolerant to overclocking. It might seem to be working okay but get errors which may not be obvious. The jumper is to select which crystal the NPU uses.

WOW! You're lucky! My old 286 runs at 8mhz.

These boards are which could have a 486SLC upgrade, even a clock tripling 100 Mhz one? So an overclock like 33mhz could be doable with a select Harris 25mhz, if the RAM can properly keep up, 50ns, 40ns?
