Hi i recently got this beauty, wanna know more about her. There are almost none markings, just the "REV 2.2 1991,8.". The chipset is SIS85c401/2. Looked up whole net and didnt find anything even similar. Most of them have lower number of jumpers, this one has 16 of them... not sure if i want to put …

Hi Tomasz, on the photo, there is the bios ident number. I do not have those files.

I think it was a resolution issue, preprogrammed in the classic wb package. Solved it by just changing it for some lower one. Final fix was me getting an individsion flicker fixer so the problem is gone forever.

Hi, found the same board known as PC-410, here is a full manual for it: https://theretroweb.com/motherboard/manual/41 … 6c877468027.pdf

I see a lot of corrosion near the keyboard connector, the battery leaked like 5/10. You have to clean it and try to bridge the broken traces with some wires to make this work. I have exact the same problem.

Oh yes forgot to mention: first thing i did was a recap. Since it was some time ago I forgot there where small signs of damage in soldermask, around the caps near IDE connector, i used a pcb varnish to cover them up. Maybe theres an issue? About icons, i found something like "Icon.library by Peter …

Hello, I'm new to A1200, since now Ive only worked on the A600s. Anyway, i put a cwb advsp distro on my cf card, booted it and I see some rather strong flickering across all my screen, and the icons looks damaged/scrambled aswell. I post the pictures of this. Im sure it can be fixed, just don know …

So she's finally alive! After I installed the memory that came, I had the board working for one time, but then I got the same parity or it kinda booted but soon after the "American Megatrends" logo it then displayed "CMOS INOPERATIONAL SYSTEM HALTED". So I've read some threads here about …

What if you disable the conflicting signals, and just leave GNG and VCC ? I mean this single board PC should only need them and nothing else? I am wondering if I could just "block" contacts on ISA card by for example capton tape? https://en.wikipedia.org/wiki/Industry_Standard_Architecture#/media/ …

Did you search for 514256 ...think they should work? You can also look on old VGA cards for some matching ones... I was looking for HY534256S-70, saw another thread on forum with a mobo with these chips. Also it has a smaller DIP16 chips, i guess these are for parity? Do i need the DIP16 or Its …

Aw, I should assume the manual is for more modern boards :) So there is a 100% problem with access to the RAM, so basically two options I could try: 1. Analyze the traces on the board - I do a lot of board repairs, via replacement, trace repair, recaps, small IC replacement, transistors, and so on. …

Hi again, thank you very much for helping me out!I took your advice, but still no success :( I've purchased a parity rams, put them (sim1, sim1-2, sim1-4) - still 3 beeps. I've also purchased a POST diagnostic card, and what's interesting I have a "100C" code, which according to manual means (in my …

Kindly thank you for the informative responses, and for helping me out. Now, thanks to you I understand the RAM concept on these motherboards better. Parity sure rings a bell, I even have some 30 pin SIPP sticks, but they are not in a comb form. Unfortunately I have no DIP memory, as this is my only …

Hello, this is my first ever attempt to run an 286 mobo. I have no documentation, also it has no model number. It has a sticker "Medicat-systems" which i assume this mobo been used in some medical aparature. It has a soldered in AMD 16MHz CPU, AMI bios, it had a battery corrosion damage which I …

I've replaced the mosfet and some capacitors nearby. Now the mobo works with intel mmx166 and 133 no mmx aswell. Gonna test other cpus later on. Still have minor tweaks to do tho.

Yep, worth to try. Thanks for quick response.

Did you manage to make the board posting? I'm asking because I have a hard time booting it too, although my version is 2.1 AL9. I have a similar simptoms with Q1 mosfet above the processor near the ATX plug. The reading between the Drain and Source is about 045, and the Gate and Drain is 018. I …
