Re: Olivetti GO481 video card

If the Olivetti GO481 only came in a 256K version, then it's not unreasonable to expect the user to know that or look it up. The fact that the PVGA1A itself supported 512K and 1M boards doesn't really seem relevant here. In any case, if we were to decide that it's worth making the memory size explic...

Re: Olivetti GO481 video card

The amount of memory is surely 256K B , not 256K b (32KB), right? I know it's a minor detail, but I can see some potential for user confusion here, so it should probably be corrected. And for that matter, isn't it a bit inconsistent to be listing the memory amount right in the displayed name of the ...

Re: Recommended settings for bog-standard i286

Something I've always wondered about: why is the video speed user-selectable? Won't there always be a single most sensible value for that setting for any given board choice and machine configuration? As such, wouldn't it make more sense for PCem to simply work out which video speed setting is approp...

Great work, basic2004! Should the amber really be as red as that, though? My recollection, which is seemingly consistent with what I can see in screenshots and on YouTube, is a bit different from the palette you've chosen--I'd say every shade on the amber should be moved a few notches closer to yell...

Re: ST-412/ST-506/ESDI hard drive emulation?

Apologies if I'm missing something obvious here, but why is the IBM ESDI Fixed Disk Controller marked "is_mfm" for PCem's purposes, while the Western Digital WD1007V-SE1 ESDI controller is not? Is this related to what was mentioned a bit upthread about the IBM controller being limited to two drives?

AGI stalls?

Quick question for Sarah: does the CPU emulation currently make any attempt to account for the latencies caused by AGI stalls? As I look at the "elements taken into account" and "elements not taken into account" lists at the top of codegen_timing_pentium.c, for example, I'm not seeing any mention of...

Re: Issues with EGA emulation

That's interesting, but still suggests something like an improper pointer or improperly defined/allocated memory or I/O somewhere in vid_ega.c or vid_ega.h, I would think. The weird probing that the IBM EGA BIOS does is likely hitting some rarely used port or memory edge case or something that the S...

Re: [Patch] CGA monochrome & selectable mono display

The difference between a monochrome EGA or VGA monitor and a color RGB one should be fairly self-explanatory, no? ;)

Seriously, monochrome EGA and VGA monitors weren't very common, but they were a thing. I just thought it'd be fun to extend the monochrome CGA support to cover them.
