As I understand, the most recent arache versions (https://www.glennmcc.org/arachne/) are provided either optimised for a 387 system, or general purpose one for the 8086. I have a 286 system with an FPU and am curious to see if there would be much of a performance difference using the FPU and maybe …

That’s the original drive in its case - I have one but it got a bit beaten up in the post. It should connect to the CT1810 controller card, of which there are some available cheap on eBay. It is also 37-pin and has an audio connector as well to mate up to your drive. Edit: I see you have the cable! …

I recently picked up an old external cdrom and I found that the drive inside the casing was the creative cr-563b; I intend to just take the drive out as use it for an internal drive in an old system. However, I couldn't find much information on what exact model this external enclosed one is or what …

I have some a USB->26 pin floppy adaptor pulled from an old USB external floppy; I am trying to use the adaptor with a standard 34 pin floppy drive and I can't seem to figure out how to wire the 26->34 pin adaptor. I have tried using some old off-the-shelf adaptors from servers. With those adaptors …

That is what I have been suspecting. Are you aware of any decent MFM controllers that support 12.5mhz systems? Or if I just happen to come across some is there any decent ways of determining whether or not it may support 12.5mhz? I do not know of any either. If a video card do know some ISA …

I think the MFM card just can't keep up and your motherboard is perfectly fine That is what I have been suspecting. Are you aware of any decent MFM controllers that support 12.5mhz systems? Or if I just happen to come across some is there any decent ways of determining whether or not it may support …

Thanks for the better pictures ! Going back a bit OT: Agree with Max. Sure some adapters could run on a faster ISA bus than standard like some VLB Video cards could run faster than the "standard" 33Mhz though usually you have jumper some wait-states in (for VLB both on the board and the adapter). …

Ok, do you know all the jumper settings for your board ? Saw the pictures but hard to tell which crystal you replaced. One rectangular near floppy stuff is Y4 24Mhz in the picture. The others y1, y2, y3 look stock but hard to tell... So which did you replace? Also curious why you want to overclock …

Can you take a good picture of your board ? Hmm yes many old ISA cards only work well at the designed 8Mhz (max of about 8.5Mhz), many newer ISA cards can work up to about 10Mhz or more. Since you overclocked cpu by 125%, and if the ISA bus clock is derived off the cpu crystal thru dividers/ …

I recently "overclocked" an AT clone system from 10mhz to 12.5mhz by replacing the crystal, everything seems to be fine except for the MFM hard drive (st251) I am unable to boot from it, read from it, etc. However, it does initialise fine on startup. I can boot from an IDE drive on xtide. but when I …

How's your desoldering chops? You might want to socket and replace the 765 I wouldn't have much of a problem removing the chip but I don't have any replacements readily available and I would have to buy one. It would take a very long time for a replacement 765 to arrive so I would like to try other …

So what are you going to use all the ISA slots for ? Those 8-bit slots are somewhat useless on a 286 except for possibly using an add-in floppy controller (even the 16 bit ISA IDE/floppy cards work in an 8 bit slot for floppy purposes) As for trouble shooting cannot see much with that picture. Can …

Hi, I have an AT clone 80286 motherboard with an integrated floppy controller that, very recently, has been acting very strange. When I boot up the system it will detect both drives and they will perform a head-seek without issue. It will (sometimes) boot from a 720k disk and very rarely from a 1. …
