Hi. I need a WD1002A-WX1 HD controller card and the on the ROM chip the serial must say 62-000094- or later. I have to have "SUPERBIOS". Better if later, but a 62-000094- serial ought to work.
I'm running an AT PII 350 Mhz PC (MS-6119), which has ISA slots, (which is a system much later than the cards I know), but it seems the AGP video card I have now is writing down code in RAM which is slated for the WD card. So, I also want a video card that won't do that. So, maybe I ought to try an 8 bit card video card because there might be a better chance code associated with the video card wont reach up to C800:0000 area.
I don't know whether 8 bit video cards did VGA, but obviously I'd go for a VGA card if they were available.
I want the cards to be known to be working.
Reason for the cards: I want to run a seagate ST-225 - temporarily! :c)Thanks.

Just one other thing:
What I'm trying to do might not work I know, because I'm running an AT PC (1998 vintage), and the HD controller and ST-225 were really meant to be used with PC/XT mobo (but supposed to work with AT if a jumper is changed).
Just curious, does anyone have an old PC/XT mobo, because that ought to certainly work with the cards I'm after. The PSU I currently have is a 20 pin one. I don't know if 20 pin fits PC/XT or not. Thanks.

Got a couple of 286 motherboards stashed away somewhere..... plus 386 stuff but no 8086 as far as I know.
I've also got some ISA HDD controllers, but need to make a journey into the loft to see what's there :-))

Hi. I think only the WD1002A-WX1 works with the ST-225 MFM drive. A whole bunch of Western Digital controllers are focused on RLL, but I think RLL is nothing much to do with the old ST-225.
The guy on Ebay that is selling the correct WD controllers won't ship to UK. :c(
I now wish I had not trashed two Amstrad 1512's! The WD controller I mention did work in the 1512's. I did the bit, you known, DEBUG C800:5.
Folks are advising me there is more chance of success running the ST-225 having an older mobo than I do have.
Once I've looked at what's on the ST-225's and shreded any personal files, that will be it.

That's the 2-ribbon cable version IIRC?
I think as long as the adapter is bus-compatible there shouldn't be a problem, we've got an old Olivetti M24 downstairs in the workshop but I think that has Olivetti's own drive solution. Has a 10mb HDD by memory, cost a fortune in those days!

Yes, it's a 2 ribbob job. I've got the ribbons, but no working WD1002A-WX1 card. That's the only card I've ever had any dealings with from the old days. I've no idea about other 8 bit cards being suitable for the ST-225.
The problem I see though, is that if I get a WD1002A-WX1, which I'm familiar with, there a chance it won't work in the board.
I've just now asked, on Vintage Computer Forum, if someone will do a test with the ST-225 and WD1002A-WX1 card, or whatever card that's working on their system, and to report the details. Maybe when I get a reoport I might know exactly what I need.
I know that the Amstrad PC1512 board works with the card and ST-225, but that mobo might be something of a rarity. :c)

Most 16-bit ISA VGA cards should be fine. You'd probably need to avoid anything with VESA support though, which rules out any PCI cards.

Nice site:
When I've been seeking and looking at controllers I only know that WD1002A worked with the Seagate ST-225.
I think actual way to find out what controllers work is to ignore "ST-225" and go by the "Standard" ST506/412.
Yes, ST506 was a Seagate drive, but it created standard ST505 "type" drives.
However, I think only MFM are really suitable for the ST-225 HD I have.
Going by this approach I think (tell me if I'm wrong) all of the following model numbers (all 8 bit ISA) are acceptable cards for the ST-225 HD:

*Gulp* I've never got my hands dirty with these sort of cards so I better not speculate. However, it does look a bit that way. And of course these device bristle with jumpers too, for honing things to one's liking.
Best of luck - there will be something out there. -- Roger Hunt

Yeah, I meant PCI or later. You can see that your card is stomping everything from C0000 to CEC00. Apparently EGA cards normally used 16-24k of BIOS while VGA cards used 24-32k, so you probably wouldn't get away with anything above that.

I used a DOS program called sa53s.
And I was not running Windows when I ran the program.

Hi. Some other few cards might work than WX1 I've discovered so, depending how things go elsewhere actually, I may make another call for a HD controller in the NG.

Yes you're partially correct in thinking RLL is nothing to do with the ST-225. The original standard (ST-506 or ST-412) was also known as MFM (modified Frequency Modulation) and the RLL cards were brought out later as a way to get more data on the drives (from memory roughly 1.5 times the data) and usually were only used on special RLL certified drives but some users took the risk and used them on MFM drives anyway and found they worked fine on some drives but slowly lost data on others.
Back then there were sometimes compatibility problems between controllers as well (even 2 of same make and model) which would cause corrupt data when drives were moved between machines so you could only completely guarantee the data if the drive was used in the same machine it was low level formatted on. I remember it also being a recommendation to always leave the PC on for a while to warm up before low level formatting as well due to platter expansion with head causing data loss because of timing problems if formatted cold and used warm.
Your comment about seagate creating the standard was also only partly correct - the ST506 drive was actually made by Shugart Technology (the company was started by Alan Shugart) before the company changed their name to Seagate.
Check your drive carefully as if it's an ST-255 then the data should be written in MFM mode but if it's an ST-225R then you'll need an RLL card.
I'm also not sure if bearings seizing up was a problem on these old drives either (so the drive doesn't spin up when power is applied) - I've had this problem with IDE drives if not used for 5-10 years but it's possible the slower running of the older drives has prevented this problem.
Are you trying to recover lost data from the drive or just making sure it's clean for disposal - if just preparing it for disposal then a sledge hammer through the platters is a more effective solution (and a lot more fun too).

1.5 is right. I had a 20 MB drive with an RLL controller. It was sold to me as a 30 MB drive and controller. I might have complained but it ran faultlessly for 4 years daily use and occasional use after that, in my Amstrad PC1512. Still in good working order when it went to the tip.

Hi. What is it, is that I've mounted an oldish (1998) PC system on a wooden board, to be used for messing around with. The motherboard is a MS-6119 AT, Slot 1, PII, 350 Mhz and it has ISA slots.
I've got a couple of ST-225 HD's, and if I can, first I want to try to see what data is on them. If I can do that, fine, then I'd shred the files, possibly format and let the ST-225's to those who might want to own a vintage HD (Some do). If I cannot see the files for some reason, then I'd just format.
The drives I have were formatted and the data written with the WD1002A-WX1 (WD1) 8 bit controller card, run with Amstrad 1512. I have a WD1, but I suspect it's dead. Interestingly this card has an "AT mode enabled" option. It might turn out, that to access the drive I need to have a WD1, not just any card that works with ST-225 drives (or type ST505 ST412).
I've had someone test the WD1 with a similar-ish mobo to mine. They disabled IDE. But in the end, only by trying with my mobo will I know if I can run the ST-22. One known problem with my system is the AGP video card. It lays down code all over C800:0000 area which is where the format program is run (WD1 contains in internal fomatting & setup program). I must use DEBUG and type C800:5 at to get the format/setup program working).
So, I need a new controller card and a new video card. Although there are many cards compatible with ST506 standard, a very few (8 bit cards anyway) are AT compatible I think.
Those cards that seem compatible (in theory) with my AT board appear to be:
16 bit: QUESTION: ARE ALL 16 BIT COMTROLLER CARDS AT COMPATIBLE? I assume they are.
It might be wise to get a new 8 bit WD1, because the ST-225's were setup with this card. But I do know, maybe any Western Digital 16 bit card will do. On the video card, it would need to be a basic one, well, it must not clogg up the C800:0000 area.
I need I think to make another advert after considering my options.

Actually, things have taken a turn. I found a video card hiding under a pile of paper and using that gave a chance for the WD1002A-WX1 that I have already to operate. I found that WD1002A-WX1 is in fact working. So, I need neither controller cards, nor video card. Thanks for the help rendered though. Rich

Don't you hate it when that happens - happened to me several times, you buy something thinking your old one has been permanently lost then find it the next day.

Yep, I've made tons of posts on video cards and controller cards in relation to the issue I have, then 1 foot away from me, placed unkowingly under a bunch of papers, is the card I'd forgotten about, the thing that would have saved myself, and a few others time, Apologies for wasting folks time a bit. I was mad at myself when I found the video card. :C)

One solution would be to use old video cards as paperweights, rather than sheets of paper as old video card-weights. -- Roger Hunt
