What PC would you run the CRT? If purely DOS (eg. 486/Pentium), the 15" would be fine and lower resolution games will look better. Go the 17" if you are also running Windows and if it's a later system like a Pentium 2 and above. If you can, test both.

Sometimes, things just work well and run better than they should. I always found Pentium 4s smoother to use than Athlon XPs, for example, with similar specs

I bought the panel from a Chinese online store called "abctay.com". Paid 50$ (+shipping, taxes, customs..) so not cheap, but I was unable to find these from European sellers or locally. It was bit of a gamble to buy from some random shop, but the panel is working and seems to be new old stock. I …

Thing about retro hardware is if you can keep it cooler than spec, keep it cooler. You could probably pry it off by putting the CPU in a few antistatic bags in your freezer for 1 hour, then prying it off with a screwdriver if keen though. However, sounds like it's happy left as is.

From my experience - multiple "Goteks" purchased from random eBay sellers - they've all been the same. Initially a bit tricky wiring and detecting for a firmware flash, after this plain sailing.

All voltages are within normal range +/- 10% - usually are a little higher without load as well. -12V is a common rail in many computer power supplies - voltages can be either positive or negative

No, but I'm interested and agree sourcing the polarizing film from an old LCD TV would be the most cost effective method. Removing the existing film would be tricky - I'd prewarm the panel (something like a 3D printer heated bed would be good) before touching and peeling the old film off

I can't vouch for Japanese cards, but in terms of cross platform compatibility between Windows and Mac OS, no - by and large cardbus cards apart from some network cards, wireless cards are not compatible. Cardbus USB cards are mostly cross platform however. SCSI cardbus cards are not cross platform …

Playing around with more BIOS settings reveals much better stability; AT bus clock @ 7.xxx Mhz works well, as does setting L1:WB and L2:WB (even though it's still set to L2:WT, but I just came across this thread with a WB patch) https://www.vogons.org/viewtopic.php?f=25&t=70318&p=803772#p803772 …

In my case, the I/O VLB controller + SD card adapter was causing all the major issues (including graphical corruption/freezes). Once I replaced the VLB controller with a different one, and also switched to a case bracket CF adapter, all graphical issues/freezes were completely gone. We seem to have …
