Dude, that's going to look sick.

Finally got floppy drive #3 to work in my 386 machine and the MR BIOS almost works, but it keeps saying Please Wait on the screen or shows the blinking cursor after the RAM count.

You will eventually get it to work 😀 Was it my C64 that you were referring to? If so, then yes. When it is done, then I might get an ATX case with a window on the side.

My favorite card in my PII DOS development machine is my Matrox Millennium II. Unfortunately it doesn't run Keen well. Today I was able to fix that.

The first issue is the color palette is all messed up. It turns out this is an issue with how the card implements the EGA overscan/border color. That color actually "tints" the palette on screen. I also saw this issue with 3DFX Voodoo 3/4/5. I was able to fix this by setting the border color to black - actually, this is recommended in Richard Ferraro's book "Programmer's Guide to the EGA and VGA Cards."

Second was scrolling. I located the scroll code in my copies of Keen 4/5/6 and took a whack at it, but then I found patches. I haven't fully digested what the scrolling patch does differently, but they use the original scroll code from the Keen4 shareware 1.0 demo.

With both of these combined, Keen Galaxy engine games work fine on Matrox. A patch to set the border color to 0 was enough to fix 3dfx. I reproduce some of the issues in cksrcmod so I could change the code before writing a patch.

Is there something like a DOS TSR that routes PC speaker sound to a standard Adlib / SoundBlaster through software? A card with a PC Speaker in is almost necessary for some of these older games.

Will dig thru my game archives, have some odd old stuff that may do that.

Hate posting a reply and have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. 🤣 Second computer a 286 12Mhz with real IDE drive ! After that came 386, 486, Pentium, P.Pro and everything after....

Thanks for posting this I didn't realise that a patch existed - I'm a Millennium fan but aren't using mine currently, mainly because of this issue. I'll give this a try.

No problem. Even with the scroll patch, you will need to set the border color to 0 if you have the palette problem. (B+F10 cheat)

Yeah, the T4800 I have suffered the same fate (resume batter leak), and it was clear the previous (not the seller) found out and removed it. There wasn't much damage, would need a serious cleaning. Just powder everywhere.
But I do agree, the proper glass covering just makes it look different compared to plastic covered. It's also much easier to clean.

But yeah the 4400's have a proper socket. Shame they don't have the expansion abilities (or even integrated sound) because with a x5+voltage shim and a recelled, higher capacity battery they would have been killer portable DOS gaming machines.

Today's retro activity: I am true to my word. I went ahead and stuffed the 63MHz Overdrive in my T4400C.

Sadly I didn't take a picture of the underside to show the rigging, but it was essentially this: Re: This 486, can mount the pentium overdrive?

I selected the Overdrive not for performance, but for the full Pentium compatibility. In this case the fan was removed so it would fit in there (not much space) as well as to disable the multiplier as it isn't being supplied through enough power pins. I didn't want to risk it with this portable (by pulling too much amps through the pins supplying power). Not to mention the lack of airflow in this laptop.
Running at 25MHz isn't stellar. It's still a wee slow, but there is a noticeable performance increase in certain areas. I just need more ram.

Fixed an SiS 6326 PCI that I was told was dead... replaced broken capacitor and she lit right up and worked fine! 4MB card too.
Also fixed an S3 Trio64V+ that had one of the tiny surface mount legs on a VRAM chip fall off. Replaced the leg with a clipping from the capacitor legs of that SiS I fixed before it haha. Tricky moves, but it works!

I rescue old PCs and keep them from being recycled/melted down 😀

Changed caps on the Compaq VDU internal monitor header board I made for the Paradise EGA card.

Tested the Genoa EGA card in the system and it made the monitor wobble the picture (will test it in my Wyse WY-2108 PC once I get a real keyboard for it) and did a shell swap on my DMG-01 to the original one with disasters: the new display is off-center and the direction pad doesn't work very well, including the other rebuild I did.

Found an IBM Aptiva E-series 175 outside, but it was heavily exposed to the elements because the case and cd-drive are rusted and the bottom of the case and are around the modem card was caked in leaves and muck.

sounds like a good rescue story for the "i recently found this hardware" thread, are you going to restore it? it's surprising what electronics can put up with sometimes

I don't know. i don't really have the space to work on things. And I don't know anything about really restoring a computer. I tried to at least disassemble it and remove the motherboard but something I can't see is holding it in place.

a mystery screw usually, maybe its rusted into place ! Sounds like this one would take some time to set right, might be beyond (reasonable) repair unless you know of an enthusiast who'd take it

Holy crap... that's a lot of computers. I might show this picture to my wife when she complains about me piling up too much retro stuff (around 15 machines currently). 😁

Running out of storage space?

not enough keyboards to match?
