A diagnostic card. I'll try it later to see if it works. Seems to have more options and info than most Chinese cards. There was a thread for this here on Vogons, but sadly now manual. It seems a pretty straight forward thing though, even if the extra BIOS chips were not included. Far from the …

Edit: I did forget.. The T56 and the newer incarnations of the TL866 lost the ability to program classic EPROMs with 21V and 24V (25V) programming voltage.. In order to program these, a hack and a separate power supply is required. Do you have any guide at hand to post here? I'll for sure read or …

I've seen ppl on yt soldering chips on them. Probably yes, as it allows chips not fitting in other adapters.

It really depends on what motherboards you have. 286-Ryzen :) So, 64/128/256/512KB Dip-xx (covers a lot). These aren't used in modern motherboards. I usually play with old stuff like 80286 - S775 Some boards are still 15+ years old and have a plcc. I know I'll have time around Xmas/New Year to do …

Sometimes you make people accept the idea of new rules. Afterward you refine the legislation. Many EU regulations express general principles that need to be expanded, maybe needing years to be effective as intended. The EU has done many great things but it's not easy to have everyone comply at once. …

Ok, back to post n.1 Are there more suggestions on chip models I should buy? I have in mind some kind of starter kit with multiple "usually" used blank chips to have at hand. I don't know much on the subject.

If I can't get it to work, I would not mind giving it away, but main problem in my country is the shipping cost when sending something to other countries. That is why you don't see people from my country selling stuff on ebay and it would probably be even more of a problem when sending something …

Hello lovely people! I'd like to buy a programmer but as there are many I need your advice. My first thought is on the TL866, there are many versions and I don't get the difference. Main purpose is BIOS flashing, specially for old motherboards that need some pimping (larger HDs, and/or just newer …

Here's a photo of my board and a close up of the bios with the sticker removed. I'm not sure if this is an eeprom or eprom. If I can't program it myself I'll have to get someone to burn a chip for me. Playing around with the computer again today and I'm no further along. Still works with 512k but …

A simple continuity check on the first 8-bit slot could help. As SSorpio suggests maybe you have broken trace affecting all. Could be data, address...

I have no markings on my BIOS chip. No window. Just 57085-1 printed under it. If I try to flash it with a lower voltage, 5 instead of 12? With higher I'm gonna fry it, if from 5 to 12.

Can I ask if you ever got the bios flashed and if so what tool did you use to do it? I've been banging my head off a wall trying to upgrade my M912 with real cache. Installed 1MB (only cost me £20) but it just hangs at post. If I change the jumpers to only use 1 bank it works fine at 512kb. Oddly …

Have you checked voltages with a multimeter? Shortcircuits? Do you have a spare cpu? Yes, a cheap chinese post card would help troubleshooting.

Check if all the legs of all components are solid soldered to their pads. It could be a bad bios too; and lower right corner of pic there's is a trace looking broken. Could you post pics of the back?
