So, I successfully took off the battery and replaced it. Also, I replaced the old 40MB HDD with a 256MB compact flash card. I managed to boot from floppy and successfully installed MSDOS 6.22. However, once finished it says it completed and wants me to reboot the machine. When I do so, after post, …

Once I have it up and running again, I am happy to backup the bios for you. Which tool should I use for that? Also, I just bought 4 1mb SIMMs and I think I found a source who can deliver me 4 of those adapters (great tip, thanks!).. Another noob question, sorry.. once those get in, according to the …

Thanks for your feedback! Oh so it's an AT? Thought it would be an XT... :) I checked the battery and it has not leaked :) Ill put in a vga card - let's see. What would be a reasonable asking price you think? Also, as Id like to learn.. How can you tell it's an 286? (or for example solely the fact …

Ok, so google let me to: https://www.youtube.com/watch?v=8LzCB6kDVC8 (phils computer lab) And I am a bit confused, are you sure this is relevant for my question? It seems to be to bypass the 504mb limit, but I don't see how that's related? The Gotek presents any mounted disc image as a 1.44mb floppy …

Hi all, Hope someone can advise.. In my recent retro built I am using a Gotek floppy simulator. When I boot from one of the virtual floppies on it (win98se bootdisk or dos 6.22 install disk #1) it works flawlessly - I can change the disk and it works perfectly. However, after installing ms dos 6.22 …

😀 Try calling them? Especially if it is a smaller store, you might have the luck that the owner likes your story and is willing to help. Also, he probably sees it as old junk anyway, happy to sell anything of it in the first place in that case 😀

Can't you just reach out to employees in the shop, explaining what you are trying to do and see if you could buy a bunch of hardware, test it at home, and return whatever was unusable?

Great, thanks! Now, to be sure.. The socket is bigger than the chip. I believe I should center it in the socket, right? Leaving the rows of holes on the egdes unpopulated, correct? thanks :) ..and it is a 3167 or 80387, if you happen to know please? (and as I like to learn: whats the difference …

Hi all, Two quick questions. I bought an IIT 4C87DLC-40 coprocessor for my new 386 build. On my board I need to jumper it for either an '80387' or '3167' type of NPU. Which of the both should I set and what is the difference? Also, the socket ofn my board looks like this: https://i.ibb.co/jT3Y6cc/ …
