I think that bios has ISO 8859 (type 2?) / Latin 2 character set. Your funky character in c:\ is a "D" with stroke in it. very strange it modified characters below 128! usually all codepage changes were 128-255.

Those opcodes you've mentioned are the non-sugar versions, e.g. for generic disassembly without knowing the context(since context is unknown in single instruction disassembly(not depending on other instructions))? As is the case with my emulator, UniPCemu? You cant ever know the context because it …

what do you mean there are multiple jcc opcodes? (some have multiple syntactic sugar names for the same opcode. ie: 75 is jnz but can also be 'jne' but jne is just sugar for jnz. 70 - jo 71 - jno 72 - jc 73 - jnc 74 - jz 75 - jnz 76 - jb 77 - jnbe 78 - js 79 - jns 7a - jp 7b - jnp 7c - jl 7d - jge …

My question is this: is the memory that's usually within the memory hole mapped higher in RAM(thus the memory holes actually resolve no RAM when the ROMs are disabled). From a program's point of view, having 1MB+386K(with 16MB physical RAM installed) of RAM within the memory holes makes 1MB and …

a 1.5 is a 1.0 without the cms chips, so a 1.xx DSP, but some had v2.00 DSP from factory, and some were user upgraded to 2.00 as Creative offered it as an upgrade chip separate. so you could have a v1.? or v2.0 dsp... without running a tool to check, its will be unknown.

this seems like a problem looking for a solution. better solution exists, external mixer and its more functional. multiple machines, multiple external midi, etc. (I have the rolls, its awesome) https://dt7v1i9vyp3mf.cloudfront.net/styles/news_large/s3/imagelibrary/r/rollsfront- …

wfw311 preadted win95+LFN by a lot. You have to patch DOS itself to even start win311 on dos7. I believe Keropi posted patches. google shows this thread; Making Windows 3.11 work in DOS7.10 (patches inside)

Unless you have a dedicated CGA or EGA monitor, I'd just go with VGA and use a 2port KVM with your 286 so you can share 1 monitor.

4.01 just took up more memory than 3.3 for no benefit most people could see, and then 5 came out with its fancy load everything high umb which made 4.01 look even worse. 4.01 was a stopgap dos that worked with larger partitions than 3.3 could (32mb max in dos3, dos4 let this go to 2gb or something). …

yeah its an 060, the oddball 3 pins on the side is a giveaway. The last 060 revision was the best 71E41J (and worth the most). All over revisions get super hot and were buggy, early revs were terrible. Even if you get the heat sink off, it could be fake markings (very very common for 060!), you need …

Yes, I am aware!:D It won't sound right, and in some cases it will sound terrible, but it should work in the sense that it shouldn't just stop at a black screen with a mouse pointer. doesnt sound like anything to do with the SC88. midi out is one way, and no games I know of, use midi in, so its …
