So I got the AMD chip up to 150 mhz with no issues however only with a multiplier of 3x so it was only ever recognized as a AMD 486DX4 Enhanced or AM5x86 P75 at multiplier of 3" Whenever I set the multiplier to 4 and the am486 P75 was Identified from the get go the cache would somehow get disabled …

Yeah I was thinking the same thing. Its a pretty cool little shop. I scouted retro supplies in the other countries I visited recently but they were all pretty minimal. Its a shame all that retro goodness being scraped. Brings a tear to my eye! 5 years ago I could get virtually anything. Now its …

It was not easy to find. The chip came from a small shop called "reverse" in DenDen town, Osaka, Japan. The guy is a huge retro computer fan but speaks no english. $5 for the cyrix-120gp picked up bulk Fast Page and EDO ram sims at $1 a packet like in the picture. I wanted to buy a lot more but was …

I've never used a 486 above 100 mhz so I don't know yet :) I guess its something I'd like to achieve - to push a 486 to its maximum potential and observe.....when I turn the cache off Its very slow - annoyingly so. Crusader No Regret and No remorse are both very close to being perfect in my opinion …

Ok I'm going to have another crack now... Were there ever any 486 boards that just didn't have a multiplier? Or wouldn't it normally be silk screened on the board? For some reason I am unable to change any cache speeds within the bios also........There's no settings for it - the bios is very simple. …

After much reading through the forums I couldn't help but notice people often recommend the ET4000 for fast dos gaming performance and game compatibility. I know the W32p is often talked about however the prices on ebay are ridiculous. I picked up a ET4000-W32i relatively cheap. I was using a VLB S3 …

Ok guys: Thank you to everyone who replied. I acquired some cache chips out of another board and now have 256 Cache(L1+L2). It appears those chips were fake and I believe the board was manufactured in Brazil. I still can only get very limited details and mentions of the Asaki board online. It is now …

Are the cache chips backwards compatible? For example If I have 15ns cache chips - Can I still run the bus at 33mhz? Also where can I download a copy of pcpbench? I seem to be having difficulty locating one.

Mau1wurf1977 Hanging notes? That's because Creative's MPU401 interfaces are buggy. If you have an AWE64 I would use that. They don't have any issues. But ideally you want a real Roland MPU401 interface. They are rare amd expensive though Sad Yeah thats exactly it. Hanging Notes. Will an Awe-32 …

Did I dream the Sound Blaster Pro 2 was working with the MT-32 or am I crazy? I was sure it was working....... I noticed with the Mt-32 and SC-55 sometimes notes get stuck.....is it because Im using a 100 mhz processor? Overflow issue ? Too fast processor?

Found this page: http://www.trinityos.com/HARDWARE/mb_benchmarks.txt It's a benchmark result of some sort and if you search "asaki" there, it has 0K Cache RAM. Probably the same board with misprinted first letter. I also suggest you search for a different cache. And don't forget the 9th cache chip …

Your right! It doesn't lag as such. I guess Ive been spoiled with 60-100fps. I just think it can move a tad smoother 😀

Heres a pic of the cache jumper settings. What is JP30 for? INTLV? Looking at JP35 this 486 board supports 128Megs of Ram? (right now its set to 0-64Megs and I have 64 megs recognized) JP39: what is 30P or 72P?
