Just got my SB16 (ct2230) today and quickly jammed it in. After an hour of fiddling with the settings it worked. Great sound in Duke Nukem 3D and win3.11

I've fixed the problem by swapping out the fans from the new PSU to old one. Required a bit of soldering but it works fine. Quiet too! I think there's a lesson to be learnt here. Not sure what it is yet but I need to find because that was an expensive fan replacement 🤣

OK, I've put the old PSU back in and it starts up fine. Looking at the new PSU it's basically an ATX with an AT P8 & P9 adapter on it. The AMPs on the new PSU are higher too. I'm concluding the higher AMPs to be the problem. New PSU: Filename 20200225_213935.jpg File size 1.12 MiB Views 359 views …

I would try a different video card Thanks for your input barleyguy. The video circuitry is built into the mother board. I've also given the ram a little wiggle and cleaned the contacts. Sadly I don't have a replacement ram module to test if it's faulty. Since the original post I've disconnected all …

Thanks for the replies guys, Just managed to haul my ass out of bed to crawl down to the computer for a quick photo shoot. This is the information I've managed to glean for the motherboard, DOS and Duke Nukem. Result from DOS Mem command: 486mem.png Fail message after running Duke Nukem: …

Hi Vogons, Thank you for your support over the years. Having just got back to my old 486 after two years in storage and attempted to run Duke Nuke 'em on it it I've been told I don't have enough memory. Off comes the case cover and a quick look at the ram shows there's one 72pin stick containing 4 …
A small assembler to practice x86
Posted on 2019-08-26, 15:25
Hi Vogons, Does anyone know of a small windows desktop program that can allow me to create a bit of x86 assembly language, run it and see how the registers are effected? It would help if it emulated a bit of memory too. I have Turbo Debugger but I can't create code on the fly, well not without …
Re: Bochs Debugger
Posted on 2019-08-23, 17:40
I think what I may do (based on what you've said) is construct a routine that outputs the segment address to the terminal and assume that's where it'll be every time I run the emulator. Does anyone have any thoughts on that?

Probably any Socket 1-3 motherboard will do. Thanks for the reply.
