i'm looking to build a 8088 or if i'm unable, a slow 286.
I dont want to do a error, i want play very old games of my childhood with the real speed of that games at that time or at least the more exact speed possible if not exactly the same. In my childhood i had a 8088 and a 8086 too. I never had a 286 but some of my friends have them.
( Right now i have several vintage pc, but the slower one are my 386 sx 16 and my 386 dx 33)
So, i have a few questions.
8088 vs 8088-2 and other cpu.
1. is it all 8088-2 cpu that run at dual speed ? ( is it all motherboard that can do it ?)
2. Is a 8088-2 at 8mhz (or 7.16mhz) from Intel or from Fujitsu or other brand, runs all 8088 games at near exact speed ? Moon Patrol is still too fast on my 386 sx-16 mhz.
How runs a authentic 4.7mhz 8088 game with a 8088-2 at 8mhz ? is it still too fast ?
3. Is a 8088-2 at 4.7mhz runs games at the exact same speed than a 8088 at 4.7mhz ?
4. I ask it, but i think i know the answer. Can a Nec V20 or V30 can run 8088 games with near exact speed? ( i think a lot of games wont run correctly thats what i read on vogons forum)
5. Is a 8086 at 4.7mhz can runs games at exact speed like a 8088 at 4.7mhz. I had both in my childhood but i can remember the difference between them in term of speed. (same question for a 8086 at 7.16mhz or 8mhz)
6. Can a slow 286 at 6mhz, 8mhz or 10mhz runs 8088 games at acceptable speed ? ( at least most of the 8088 games ) (i suppose moon patrol, frogger, lode runner, digger wont runs at all or freeze or be too fast)
7. Is the brand of the 8088 or 8086 or 286 cpu important ? Does a 286-10mhz cpu from AMDruns exactly the same than a 286-10mhz cpu from intel ? Does a 8088-2 cpu from Fujitsu runs exactly the same from a 8088-2 cpu from intel. You can answer me by comparing different kind of cpu and speed with different brand. I try to understand if the brand is a important thing. I know a nec v20 or v30 is not a real intel cpu at all, so i suppose it could be very different in some way and speed could be very different and compatibility too, is it right ?
8. I think yes, but i ask the question, is 640kb ram really needed as a minimum to runs all 8088 games, and i want to run commander keen serie and wolf3d on it, even if its slow. I think with 512kb i cant runs these games, is it right ? So what do you think as a minimum of ram that is correct, 640kb vs 512kb vs 256kb ?
I read several web pages and text since a few years, dont worry i know how to build a 8088 or 8086 system correctly, about that it be should be ok. But you could always give me some advices
Thanks. I hope my questions are the good ones and i hope i didnt forget to ask anything.

I'm interested at these xt system below, but i think both wont run 8088 games correctly. I tried to know if the 8088-2 turbo board 8mhz fujitsu motherboard and cpu can run at 4.7mhz speed too. But i cant find any confirmation. If you know it thanks to answer me.

( i dont know if it could run at 4.7mmhz )

( i dont know if it could run at 4.7mmhz.
I would prefer a intel 8088 cpu than a NEC 8088 cpu, but i really dont know if it does a difference in speed or other thing to have a real intel 8088 cpu)

(I love this last one because it has a cga rca output and right now i only have 16bit isa vga video card that are confirmed to work in 8088, but i would prefer a real cga output, but i cant find any crt cga monitor even a ega monitor is hard too sell and very expensive.)

( i dont like that fact its untested.and and i think 256kb ram will be a problem.)

( i think 256kb will be a problem and i would prefer a intel 8088 cpu than a amd 8088 cpu, but i really dont know if it does a difference in speed or other thing to have a real intel 8088 cpu. Edit: Finally i think its a Intel cpu, pictures are not good)

( not enough information and bad picture )

( seems good, but not tested, i dont know how many ram memory it have, maybe 640kb)

I still look at 286, but i think games will run too fast. Look below thanks.

( about this last one i dont like it has 8bit isa slot only, i would need a XT-IDE card, because i cant find any 8bit isa ide hdd controller. any ideas?)
Thanks for answer and help.
