Very good news ! If you can dump it do not hesitate to upload your BIOS (unless it's 100% identical (same hash) as mine) . Happy to have helped !

Re: PicoATX power supply for retro build
Posted on 2020-12-01, 15:47
Thanks for your feedback ! Yeah I thought about the LM2662 but you need negative voltage and on ATX the -12V rail is pretty weak so you might end with a weak -5V also I guess?

For testing purposes I use an ATX2AT (x86.fr) but I'm on the lookout for a simpler solution (less bell and whistles) for mobo I've tested and I want be put to use, so a PSU dedicated for AT machine (-5V, bigger 5V power rail, etc...) will be awesome.!It seems some guys from Poland have something …

Surprised to not see any mention of this awesome gadget : https://x86.fr/atx2at-smart-converter/ It'as an active ATX to AT converter with builtin overload protection. Very useful when you've got a mobo in an unknow condition and want to test it withotu damaging it nor your PSU. I'm not affiliated …

Can you enable the loading of dasddrvr.sys (commented out in your config.sys) and see is there's any improvement? It's a hotfix for buggy PS/2 BIOS that was designed for PC-DOS 3.30 and higher but it's not clear if MS-DOS solve these issues (click here for a list of these ). If you don't have the …

Thanks for your thorough feedback ! Please upload the BIOS here or better, on Vogons Drivers (there's a dedicated topic to it in the forum). Cheers !

Yes I was thinking of this also but ideally i'd like to refrain from modding to much.
3.6V battery modern replacement
Posted on 2020-09-23, 15:03
I just finished restoring my Macintosh SE/30 motherboard by doing a capkit and cleaning all the gunk with litres and litres of IPA (the alcohol not the beer silly). Thankfully the PRAM battery didn't leak so that was one thing less to deal with. Now I'm faced with the task of replacing the battery …
Re: Can anyone recommend a low cost PSU from Amazon that would work well with retro hardware?
Posted on 2020-09-23, 14:45
If it just for testing purpose you could use a standard ATX PSU (Seasonic and Corsair make great ones) along with an ATX adapter like this one [https://x86.fr/atx2at-smart-converter/] to protect your mobo. I'm not affiliated with this project, I just happen to have one and can vouch for how nice it …

Thanks shamino and Jo22, I'll keep that in mind. i'm now focused on flashing a new video BIOS to see if that's not a BIOS issue. I'll test with the BIOS from this page (http://www.vgamuseum.info/index.php/cpu/item/127-cirrus-logic-cl-gd610-620-c) and maybe matze79 will release its VGA BIOS from his/ …

Would you be so kind as to dump the EPROM of it ? I fear mine might be corrupted

Just a dumb question: do you have a "delete" key on your keeb ? Got no such keys of mine so I have to plug another keeb each time I want to enter the BIOS which is quite cumbersome.

I just compared your pics from my card and I noticed that on mine jumper JP1 was set up on pin 1-2 while on yours it seems to be on pin 2-3. Also my external dipswitches are as follow (1 to 8, 0 is off, 1 is on) : 00110110 I still haven't got my hands on this card manual so I don't really know what …

If it can help graphical mode is ok : I blindly started Doom and up until the initialisation (text mode) it's garbled but upon the appearance of the title screen (graphic almode) all is good. I begin to think that maybe the BIOS ROM might be slightly corrupted, at least on the code page level/ …

Does anyone encountered graphical issues/glitches while switching between video modes on a ISA graphic card (especially at boot)? It might give me a hint of what's going on. If anyone knows a testing program that switch video modes on demand that could help me doing a diagnostic here.

Thanks for your feedback. Seeing how the ramdac (Suntac GS02760-50) is socketed should give us a hint that maybe this was a problematic chip that would have to be replaced when RMA'ed. If I were you I'd start by replacing this chip !
