Ok, i lost my 29160 bid to someone else (volontarily)
I take a 2940U2W instead, seems safer on a 486, and it's not like i'll see much difference to run Doom.
I'll begin loking for the CD drive and Hard disk drive now.

Do an ebay search for "scsi plextor" Black drives from decommissioned servers are CHEAP, beige ones tend to sell for a good $10+ more than the blacks.

I run a 50 pin version of the plextor 40TSi in my 386 setup. In fact, its what I use to terminate the end of the cable. ^.^

I'm amazed at SCSI drive prices.
Another of the things I dreamt of 20 years ago and costs the price of an entry to a movie nowadays ...
Might as well go full overkill and take a 146GB 😁
Only thing stopping me is the fact that 140 of them are never gonna be usefull, since even on my modern computer, a 80GB SSd is alrgely enough ^^

I second Plextor SCSI CD-ROM drives. I have an 8X tray loader in my XT, and a 32X caddy loader in my 486. Both of them are whisper silent. Very solidly built drives.

Well I'm constantly teared between the fact I want the old school sensation, and the fact I want something pretty usable nowadays.
I'm sure CF adapters are really good. But I I go this way, i'll end up with a 133MHz Cyrix, 256MB ram, a SSD on a PCI sata controller ... And I'll end up very sad cause i'll have something that's definitively not a 486, but still an old crap compared to today standards.
Of course, I can't go the other way completely, cause if i rebuild the 486 I really had (200mb HDD, 4MB ram, SX33 ...), i'll start it once, see that doom will run 12FPS when i'm used now to 120fps, and i'll cry too ...

So, fighting hard to find the right balance, I think i'll stick to the SCSI system 😀
If really i can't take it, i'll put the 20€ in a CF system anyway 😀

This system has my vote! Forget the DX4-100-WB, find an IBM 5x86c-100HF. I'm 1 for 2 at 133 MHz. A Promise SATA150 TX2plus is known to work well in PCI 486's. It contains both ATA and SATA ports.

I can back Feipoa up on the 133 MHz IBM 100HF chips. I'm 2 for 2 with one even running at 150MHz on certain motherboards. As for the TX2, it works like a charm.

I'm on this one : http://www.ebay.fr/itm/300739190914?_trksid=p5197.c0.m619
If no one from here outbid me 😁
But I still want a DX4-100 WB Intel @ 120 ... I'd like to have the choice and try them all 😉

Sunaiac, that is an IBM 5x86C-100GB chip. I'm not sure how well it overclocks compared to the -100HF chips. Maybe just as good?

I think the G vs. H just implies no heatsink. The B vs. F might be the revision.

Well I hope to be able to answer some time soon (that is within the next 3 month, given the speed at which i'm completing my project 😀 ), if I win the bid.

I have a very stupid question, but i can't seem to find a clear answer.
I decided to go full SCSI on my 486s, and got myself several of those (same model, not at that price of course) : http://discountechnology.com/Seagate-ST318406 … CSI-Hard-Drives

I have adaptec cards, all in 50 pins, either 2940 PCI for the PCI 486 or 2842A VLB for the ... well VLB one.

I obviously have no troubles with the speed limitation at 20mb/s, but i'm puzzled about that LVD stuff.
It seems it should work with a lvd certified adapter. Could anyone point me an ebay listing with an adapter that is sure to work ? I have 68 and 50 pins wires, but since I also got the CD burners to plug, i'd prefer a HDD side adapter.

Thanks !

edit : there's a "Force Single Ended" jumper on the HDD if it can help.

Its all about termination. The Achilles heel of scsi. Some 68 pin scsi hard drives do NOT like being on 50 pin cables. I have such a drive in my collection like this.

I would use a regular 50 pin cable, have a 50>68 adapter on the hard drive, followed by any other drives you have. Try to keep everything 50-pin.

It is a mistake to think you can solve any major problems just with potatoes.

Well the circuit would be simple : Adaptec --> HDD with 68pins adapter (the one i need to find) --> CDROM with termination on, all on 50 pin wire.

some sellers do tell about termination (http://discountechnology.com/68pin-50pin-SCSI … yte-Termination) but i'd like to find the same thing cheap on ebay, where they sadly don't tell about termination...

if the hard-drive has an internal 68 to 50 pin termination (most do) then there should not be any problems with that. the terminator you linked, would be necessary only if the drive does NOT have that form of internal termination.

I use an IDE to SD adapter. Using a microSD 512MB card works great with my 486 system. Disk access times are much much faster than any of my old hard drives with less than 2GB. Transfer speeds seems to be fast enough. And there is virtually no noise. I won't be using hard drives again.

Ok, i'll get the 3$ adapters then, and hope for the best. Worst case i fall back on the expensive ones.

Thx.

Well 3$ ones are the female ones ...
Of course male ones are 17€, but are equipped for termination.
So, too bad, i'll pay adapters ore than disks themselves ...

That's what I'll do if I fail miserably with my SCSI setup 😁

I'm using a 9GB IBM 50pin SCSI disk in my 486 with a VLB Adaptec controller. Works without issues. I have never worried about termination.

I found 18 GB 10k seagate HDD with 68 pins for peanuts, so that's what I have 😁
I'll do a progress report, just ordered some adapters 😀
