That looks promising as well, a bit more complicated than the VGA to Scart circuit, will have to order some veroboard and components and start prototyping.

Thanks, I'm planning on using the 5175 with a VGA card so the output will already be VGA / component sync, the 5175 however, requires the composite sync. PGA pinout below.

Thinking the below might work (converts the component sync signals into composite sync) but modified to output on DE9 as opposed to Scart. http://www.nexusuk.org/projects/vga2scart/circuit

Hi - I have an IBM 5175 that I'd like to convert to VGA and hook up to my IBM 5170. I've searched extensively and can find reference to a VGA modification being possible however no details of how to do it. Does anyone here have any experience or knowledge on how to carry out the conversion? The VGA …

Thanks all, I've gone ahead and got the TL866CS, UV eraser and a handful of the 27C128, 27C256 & 27C512 eprom chips from ebay. That should cover all bases and give me some spares for future projects. Now just have to wait for the boat from China!

So I'm going to attempt to update to a newer BIOS on a 286 I'm building up. The BIOS Chip Type is : http://www.radiomuseum.org/tubes/tube_r4-th018.html I'm going to get one of the USB universal programmers for the new BIOS and some replacement chips, however I can't find these chip types anywhere. …

Actually BIOS detects is fine as 32GB, but just noticed W98SE is only seeing 8GB, FDISK has the same problem reports the Drive as 8GB. Booted into XP setup and it can see the full 32GB, but not W98. Any idea why that would be?

Thanks mate, set the SSHD to 32GB and it now detects fine. Super Fast Drive for a W98 machine!

Sorry my bad, not using a PCI-SATA adaptor, using a PATA to SATA converter. I do however have a generic PCI-SATA/IDE adapter that I got off ebay a while ago, i tested it under w98SE with this mobo and it works but only with additional hard drives, couldn't see any drives connected to it during the …

Thanks for that, already using a PCI to SATA adaptor to interface the SSHD to the motherboard. I'll put the drive back into the newer machine, run Seatools and limit the capacity to down 32GB. Hopefully that will work!

Hi - I'm trying to get a Seagate SSHD working on a J-MARK J-656VXC REV 3 Motherboard: http://stason.org/TULARC/pc/motherboards/J/J-MARK-COMPUTER-CORPORATION-Pentium-J-656VXC.html I've used Seagate Seatools on another machine to limit the SSHD capacity to 128GB however the J-Mark Mobo BIOS still …
