Hi all, today i've decided to work on my 286's network functionalities today. A while back I installed a new old stock DE-220PCT network adapter for it. Today i've gotten around to getting this computer working on FTP using mTCP, but I just can't get anything to work right. I installed the packet …

Nice! Your CPU seems to do very well. I think a math co-processor would be a cool upgrade, but if you don't have anything that uses it, I wouldn't spend $35 on an 80287 XL like I did. I ordered a Tseng ET4000AX 1 MB ISA card for my 286, so when that comes, maybe my system will be a little bit more …

A couple hours ago I bought a Tseng ET4000AX 1 MB card. It uses the ISA bus and it should give my 286-10 a speed boost. I paid only 45 dollars for it and the seller says it is working. Can't wait for it to arrive so I can try it out!

Does anybody have a Award BIOS, AST BIOS, or even a generic setup utility that can set a memory wait state?

As a few of you on this fourm may know, I've been trying to make my 286 run at a faster clock speed this whole week. Well, I did that, and got it from 8 MHZ to 10 MHZ, and it runs stable under that, but I would like to push it to 12 or 16 MHZ because I bought oscillators for that. When I go up to 12 …

Yeah, im planning to buy one as i've seen how weak this video board is. Your 8 MHZ system seems a bit slow though according to the benchmark. Mine preformed like a 12 MHZ AT with a 13 MHZ 80287 when I did the test back on 8 MHZ.

Just a little update on this as it has been some time since the last post - but I did end up soldering in an oscilliator socket and I put in a new Harris 286 20 MHZ processor. The board and that processor have no trouble running at 10 MHZ. There are some minor issues however. The sound card might be …

Yesterday was a great day. For one thing, I got my 286's CPU upgraded! So far, the operation has been nothing but a success. As me and a friend were going somewhere, I told him about the soldering work I had to do on my motherboard and I how I had very little knowledge on soldering and I would need …

Yesterday, the mailman came by and delivered nice christmas cards to me and my family. Among those christmas cards however, were new parts for my 286 PC. Those parts consisted of a NOS Kraft game port joystick card, and an 80287 XL. Upon opening the package for the Kraft card, I found that the box …

Nice.. Did it come with a metal bracket? Mine was my own solder project so it's not as clean as yours. It also has a volume shaft that is a few mm longer and and lacks a metal bracket, but I think it cost me half of what you paid so I can't complaing :lol: If you really want a metal bracket, it …

Yay another adlib clone! Photos of the card? I sometimes wonder if I should replace the ES688+MusicQuest combintion in my 1987-1989 386SX25 (which is basically a stand-in 286) with Adlib+MusicQuest.. There are no games prior to 1990 that actually take advantage of SB's OPL3 or digital sound let …

Today I installed my brand new AdLib replica card into my 286 machine. The AdLib works beautifully, and it is a big improvement over the PC speaker. Tommorow's upgrades will consist of an 80287 XL, and a game port joystick card. Over the weekend, i'll do my final upgrade to the 286, which will be a …

Yeah sure, it would be interesting to see if the chipsets are the same.

What do you mean by "magical jumpers"? Also yes, the chipset is a GC102 chipset.

I did try those factory configured jumpers a while ago to change parity settings - sadly, none of those jumpers did that. None of the jumpers cleared the CMOS. 2 of them did nothing noticeable and system booted as normal, the 3rd one just made the VGA card display a white screen and not boot. Maybe …

My board has a 14.31818 MHZ oscilliator on it next to the CPU's oscilliator. Dosen't that keep the ISA bus at a fixed 7.15 MHZ or is that for something else? No clue how ISA clock speeds are derived, sorry.

Yeah, I don't think i'd be able to get to 20 MHZ either, but it's worth trying the oscillators up to 20 MHZ. I think i'd be able to get the 286-20 running at 10-12 MHZ on this board, but 16 and 20 MHZ might be not possible. Dosen't the Harris processor run a lot cooler and use less power than the …
