Landmark is a good point to start. There will be no output on the POST-card with it. You get a display only on MDA/CGA or you hear output from the speaker. You need to be patient, it may take some time until it starts.

For me it seems the battery caused quite some damage which you can see on your photo taken after the removal. This also explains why the PC still worked ten years ago. You need to check the continuity on every trace that is potentially affected. You should also fix that ceramic cap as described …

I have found an offer for a 286 PC at with a ST62 Board at local classifieds. In the screenshots I noticed the AMI BIOS is very new, 10/19/1990. I asked the seller and he was so friendly as to send a dump to me. I have tested it in PCem and added it here: https://www.vogons.org/viewtopic.php?f=46&t= …

I got this BOCA RESEARCH "8 MEG AT RAM" card. It is also labeled as "QuadRAM AT plus". It can be configured with the BOCARAM/AT PLUS drivers. Also the EMS driver works. The driver seems to support 4 cards (# seems to be selectable with jumper J1) with 8 MB each. Each card can be freely configured to …

What..hater? When I hate sombody it sounds quite different. Its of course your choice what you do with your own card. You are also free to overpaint your Picasso to adapt it to your current taste. You cannot compare this to a repair to make a card working again or a exchange of caps. This …

You can also try to keep the left mouse button pushed while powering on the PC. This will switch the protocol to MS mode 😉

Yes interesting...this a fake, right? You ruined the card to avoid to modify 2 50 cent cables..? Hope nobody else will do this.

Just found the solution...my DELL supports Composite Sync on green - simply attach the output signal to the green signal on the VGA connector 😁 Filename 20211215_201401.jpg File size 1.03 MiB Views 354 views

I only own a logic analyzer. What you can see is that the frames switch with 60 Hz. So the question is more if there is a possibility to display a 1280 x 1024 composite signal on a modern screen? Filename over.jpg File size 31.25 KiB Views 360 views Filename 60hz.jpg File size 23.5 KiB Views 360 …

Just like to share some data about the EIZO / NANAO TIGA MD-B09 TMS34010. Unlike for many other TIGA cards the driver for this card is still available. I expected to be able to connect a VGA screen to the "CN2". However this connector provides only the same signal that is available on the cinch-out …

I currently have a REV B on my desk. It is prepared to hold a relais to switch to another VGA source connected to CN3. Dont have documentation or drivers. Any ET3000 driver should work. But it would be nice to have a specific driver to make use of the emulation features indeed. http://vogonsdrivers. …
