Interesting. First time I've actually seen a motherboard with the battery in this configuration. However, after browsing a bit, I see that they were also quite common on these type of motherboards. I've always just known about the old NiCd/NiMH batteries and the button (or coin) type batteries ( …

I think you've got it covered. If you have other CPU's, maybe consider using a standard AMD or Intel 80486DX4-100, instead of the Overdrive CPU. The Overdrive CPU you selected is slighty faster than a standard Intel 80486DX4-100 with 16k L1 cache or an AMD 80486DX4-100 with 8k L1 cache (this is …

If you don't have random freezes on your machine or there is no sudden tearing or "fuzzy lines", then it should be fine. Basically, if you inserted it correctly and deep enough into the slot and you've fastened the bracket properly to the chassis, then it shouldn't give you any problems.

Yes, that is a quick way of booting straight into DOS. However, this won't load any DOS drivers or memory managers (you need to "define" that in your start up files in the relevant sections).

One possible reason for your problem is because, once you start in MS-DOS mode, you are loading certain DOS based drivers. Typing "exit" will just try to load Windows, without unloading those MS-DOS drivers, which could cause Windows to hang (for various reasons, like not enough memory available, …

I suppose I could replace the worn connector but, I would have to cut the wire and attach (solder) a new one back on. I'll see how it goes. If it really becomes worn out and doesn't want to make a connection anymore, then I'll replace it. Should be able to find a replacement 5 pin DIN connector on …

That is some breakout box. After my last post, I decided to give it one more try. I discovered that the connector on Midi out port 1 does have a bit of a lose connection. If I bend the cable a bit to the one side, then I have a connection. Probably the age and use over the years has caused the …

I managed to resolve my IRQ2 (9) conflict on the MIDI interface. Seems like the culprit was not my motherboard but, my sound card. On this particular sound card (Aztech Labs Sound Galaxy - AZT1605 chipset) you can actually specify a separate IRQ for the MPU-401 UART MIDI interface. Despite me …

Yes, SoftMPU was the next thing I wanted to test. What does the breakout box of your V24 look like? Do you perhaps have a picture of it? Do you think the breakout box of a MPU-IPC-T would work with the V22/V24?

Thanks. I did try the MIDITEST.EXE. With IRQ 2 (9) setting, no luck. With IRQ 7 setting, it does initialise. Unfortunately, no luck with the MIDI cables Will try in another motherboard.

Thanks. Does answer some of my questions. I actually also own a Roland MPU-IPC-T and have tested this card on the same motherboard on which I currently have my Roland MPU-IPC-T installed. I then tested it on another 486 motherboard and had the same problems. Seems like this card is faulty (at least, …

Hope someone can assist me. Attached is a photo of a Voyetra V-22 MIDI interface card, with its MPU-401 compatible MIDI daughterboard on the right hand side. The other two photo's shows what the MIDI interface cables looks like. V-22 with daughterboard.jpg Pic01.jpg Pic02.jpg I seem to be having …

It might seem now that the Presario 2256 is not perhaps what you need but, in a couple of years from now, you could end up kicking yourself for giving away your old machine. As the years go by, these type of hardware will become rarer and rarer. I gave away an old 486 of mine and today I want to …

Yes, you're right. On the S3 card, I traced both jumper JP4 & JP5's connection leads to the vacant memory slots. Fortunately, I have no need to expand the memory on this card since I'm using it in my old 486 PC. The current 1mb of on board memory is sufficient for playing my DOS games.

Thank you for the advice. I actually tested both cards on the old Landmark Speed test (v2.0 & v6.0). The S3 has a video speed rating of 16661 chr/ms whereas, the Cirrus Logic only managed 8777 chr/ms. For matter of interest, my old Tseng ET4000AX (16-bit ISA) card managed about 3000 chr/ms. On the …

I have these two VESA Local Bus Graphics cards. Both are in working order but, I would like to know what settings the jumpers on each card represents. The S3805 card has three jumpers on the left hand side (if viewed from the top, with the bracket on the right hand side) whereas, the Cirrus Logic …

You don't perhaps still have this daughterboard?

If I'm not mistaken, then this game does not actually support the MT-32. It was released back in late 1994 on CD which either lets me think that it utilised General MIDI for music or even CD Audio.
