It's been a while since i ran dual PCI cards. This was in an AGP 440BX system, with an AGP card too. Three head. IIRC, one of the PCI cards i tried insisted on being the primary, the other one and the AGP were secondary. I went to a dual setup because i wanted the AGP as primary.
Re: SCSI on a DX4, are there any real benefits?

only hard disk and cd-rom (rarely used). Ther are some problem on a 40Mhz bus with the vlb scsi controller? I've never ran any vlb SCSI controller. Infoworld or PC mag did a review of the adaptec and another iIRC. They match the findings of whoever said they were disappointing. You'd have to look …

In the early days of CD-Rs SCSI was better. My first IDE CD-R was terrible at eating CD-Rs. There are pluses and minuses. Depends what you want, Raw speed? probably CF on IDE, unless you can do SATA+SSD using modern tech. Period correct? SCSI drives came in faster models. If you have an IDE and SCSI …

Looking on eBay and the listings for the 2500 CPU boards are Socket 8. Yep you are right. it was the 2000/4000 that was updated to take socket 5. Here is what i have on it: http://66.113.161.23/~mR_Slug/deviceInfo/compaq/compaq_qrg/volume2/plnt2_4.html It looks like that CPU card is for it, i'd …

I have a DX50 95 with warp 4 on it and it is slow. I think 4 came out in '96 so it was 3 years old at the time. Never had the Pentium ones. Model 76/77 are probably a good buy with a DX2-66. The early 56/57 are slow, later SLC2 etc are better but my gripe with these is the 16-bit bus. These were …

6 slots? should be 8. Perhaps this was an OEM custom case.
Re: 386 on a 486 motherboard?
Posted on 2022-03-21, 19:52
I would say this is doable. You wouldn't *need* to add SRAM as cache. I remember reading about 286 to 386sx adapters being made with just a few PALs. The interfaces are different but not too dissimilar.

The only Compaqs I know of are here http://66.113.161.23/~mR_Slug/deviceInfo/comp … q_qrg/index.htm Are you sure it wasn't the Systempro XL? That was a dual 486 with an IDE RAID option. ShadowLord on vcfed.org has one I think. Didn't know of a prosignia dual 486, be cool of there was one.

About 10 years ago I had this idea of thinning down my collection buy just building the best PC money could buy for each year between 1981 and 2000. This I now look at with laughter as my thinning down consists of buying more hardware. I have managed a few years but the research I have put into it …
Re: SCSI HDD ignores Motor Start option
Posted on 2022-03-20, 12:49
You could try the delay start jumper, DS on the adapter. The drive should wait a few seconds then start up, regardless of it receiving a start command. Did you say the jumper block on the front of the drive is empty?

Yes i can understand you being frustrated if you are looking for register listings. That was never the intention of my site. Maybe some far off future thing, but I always worry if it copy something from a datasheet, I will make a mistake. Some 'datasheets' contain less than whats in the example link …

Second about the towers. Some have flimsy sides, some are pretty strong though. 19" racks can be good for stacking, though the shelving is expensive, really depends on if you can get them (and the shelves) for free. Failing that steel/wood shelving. There is also attics and basements, wish i had a …

I run an XP system on my network and I only just upgraded to sp3. Its been fine. It is behind a NAT. Ran a win 2000 server too until recently, that's been fine as well. Things seem to just chug along for me.
