Re: CRT Displays Choosing for DOS
Posted on 2021-12-19, 07:33
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
Re: What retro activity did you get up to today?
Posted on 2021-12-06, 02:02
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 …

Changed the display panel of my Libretto 100CT. The panel for this 100CT is Sharp LQ71Y03 Would you please share where you got a replacement panel from? I've a 100CT with flickering vertical lines on the left side, a common spot, I could clamp it all down and hope for better but a replacement panel …

I always quite liked WindSock as a 3.1 benchmark, what's more you get wildly different scores at times too! 😀

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.
Re: Are all "Goteks" made equal?
Posted on 2021-11-25, 04:36
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.

If you have to start doing that, TBH I'd dispose of them.

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

How much RAM do you have installed? The issue might be you have too much - see R. Lowe's 512MB RAM limitation patch: https://rloewelectronics.com/distribute/PATCH … .0/PATCHM01.HTM
Re: Has anyone changed LCD polarizing film?
Posted on 2021-11-08, 23:24
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
Re: Are PCMCIA/Cardbus cards for Windows 95/Japanese Windows/OSX the same?
Posted on 2021-11-08, 05:20
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 …

Jumper the turbo switch to ON (bottom right under cache) had the same issue with this board recently when setting up! Good to see another one resurrected.

Long time lurker, always enjoy your rebuilds and stories, Robert B! I like how you deal with the failure; that you've learnt new skills in the process and obtained better tools for future complexities - well done 😀

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 …

Just chucked an AOpen ~ 300W ATX unit - last night it started smoking, cracked it open filled with Teapo caps. All of which appeared to have decided to commit mass exodus taking out some voltage regulators. Binned.
Re: Cirrus Logic 5429 VLB issues in Windows
Posted on 2021-10-04, 02:57
Even with 2MB RAM on paper it should support higher colours at higher resolutions, but it would be the RAMDAC that's the limitation here. I've been playing around with a few VLB cards recently in Windows 3.1 (ET4000 W32i 1MB, ARK1000VL 2MB, Cirrus Logic something 2MB), apart from only the highest …
Re: SB16 crashing - hidden refresh, incompatibility with ARK1000VL card?

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 …

Hi retardware, Ah no oscilloscope is beyond me :) Prior to the ARK1000 card, I was using a Tseng ET4000 w32 which worked fine with SB16 and hidden refresh, albeit with graphical corruption in certain DOS games and demos (a future project to fix either RAM or RAMDAC issues). I've an AWE64 value or …
