Microsoft serial mouse 2.0A issue with VLB IO card
Posted on 2017-12-11, 08:33
Hi all, I have a 486 with a IWill SideJr Pro VLB IDE & multi IO controller in it. I have a Honeywell serial mouse that works with it, and a Microsoft serial mouse (2.0A) that doesn't. The MS mouse works with every other computer I've tried it on, but not with the SideJr card -- tested in DOS and …
Hard drive problem when Oak OTI087X VGA card installed
Posted on 2017-11-27, 10:04
Hi all, My 486DX2-66 works fine with my trusty Trident 8900D in it, but not this Oak OTI087X card (which works fine in a different machine). With the Oak card installed, the hard drive isn't detected and so it wants to boot from floppy. I'm guessing a conflict with the HDD controller card, but there …
Settings for E315 (UM82C862F) HDD IDE / floppy controller multi I/O?
Posted on 2017-11-27, 09:57
Hi all, I'm looking for info on jumper settings for this UM82C862F based multi I/O card. I've looked through all the I/O cards and HDD controllers on stason.org but haven't been able to find this one. There are 13 jumpers labelled J1-J13, plus JP20 for the LED, and a 2 pin JP19 hiding behind the …

No, it's the built-in panel - see the first link in my original post for pics of a similar one. It connects to the card with a 20 pin ribbon cable (see my first pic; connector is just to the left of the RAM and it looks like the same PCB design may have been used with other connector types). It can …

What kind of connector does your card have? Is it standard VGA? If yes, did you try another monitor? You did get me thinking though... The only visibly unusual thing about the PCB is where 3 VGA connector junction points appear to have been left deliberately unsoldered, as you can see here: PCB_VGA …

Ok, I take that back re the error beeps with monitor disconnected since I just had the same problem when booting my 6x86 (different VGA card) with the monitor cable out...!

Yes - it has an external VGA connector, and internal 20 pin connector for the LCD panel. I've tried it with two different CRTs, and the LCD panel (and nothing connected). I wouldn't expect error beeps from not having a monitor connected though. The error beeps follow the card to different machines - …

This is an old board that only supports up to a 33MHz 486DX. My guess would be the max ISA bus speed is limited to 8.33MHz. CLK/4 should give 8.25, thus CLK/3 lets me squeeze out a tiny bit more (negligible). A PCI machine probably lets you get more.

Your problem is the isa bus not ram, you could get some performance boost overclocking the bus from 8 to even 12 mhz but the hdd controller might fail over 10 mhz (it's already a 25% overclock) and you could get data corruption. I personally haven't even tried beyond 10 mhz on an isa system but on …

You can't ask for PCI or VLB performance out of the 16-bit ISA bus, it's a bottleneck with a dx2-66. Yep, I know that and I'm not expecting amazing performance. I just thought, hey here's a (supposedly) rubbish 8900, maybe it's worth getting another card to see what a (supposedly) better one is …

A little bit of further information: The card has 8 dip switches (external), and one 3 pin jumper, marked JP1. In the pic you can see it just near the yellow wire to the left of the switch block. Removing the jumper or moving it to the other 2 pins has no effect, nor does trying the card in an 8-bit …

I am attempting to restore an old portable LCD-386, which looks basically the same as this one . I'm not able to properly test the LCD because the video card isn't working. It's a Cirrus Logic CL-GD610/620 based card with 256kB, and since it would prove almost impossible to find a replacement, I …

Trident cards were not actually that bad, both of your cards are pretty fast for isa but of course a VLB card will be much faster. 8900D had a FIFO buffer, the cirrus is a later and better card with 24 bit color support and acceleration. Benchmarks usually don't really matter with such slow cpus, …

Hi all, First post here and very glad to have found such a great site as this - previous posts and the driver library have already been invaluable. I've been on a bit of a retro trip lately, reliving my uni days and playing old games on old hardware instead of dosbox on an i5. I've got a 486DX266 - …
