I have a A1GX, in an Acer with a Ali M1429G, maybe it have some similarity : I do have a Ti486DX2 66Mhz or 100Mhz(cache won't work at 50mhz fsb, need faster chips) You only mentioned benchmark is Speedsys Memory Throughput, here mine with corresponding FSB speed : I get 24MB/s (33fsb), 16.9MB/s( …

I just got IRC to work with TLS, 256Bit encryption, on my 486 with Windows 95b. Here are the instruction (should work for specific applications, except web browsing) I attached a zip file containing all the required stuff. 1 - copy the SSLWrap folder in program files 2 - copy the dlls in windows\ …

Si it's a NT issue, I guess that narrows things down somewhat at least? What if you use the 3 NT boot disks and the CD? I remember having trouble trying to install off the HDD way back when so still use this method to this day. I also checked my NT 3.51 post which also serves as install notes. In …

Are you able to install Win95? I'm not really sure where I am going with this but at least we would no if the problem is just with NT or all versions of windows I going to test. Now I just made another test, DBANed the hard drive, created 3 partition : * primary C 128MB, formated, empty. * logical …

I just tried by removing all ISA card, re-adding the extra RAM and disabling the cache by setting FSB to 50Mhz Same issue, flashing cursor at first reboot 🙁 Technically same setup as the NT4 install I did a month ago. That does not compute.

Hi there, Yesterday I wanted to replace my windows Nt4 install for a NT3.51 Install, on my 486 I had 2 partition : Main 1500MB DOS partition with MSDOS 6.22 and a NTFS partition with NT4 inside an extended partition. I deleted the NTFS partition and the extended partition then I deleted the NT …

After eliminating the dead chips, It's still cheaper than local sram or certified sram unfortunately. imo, they should just disclose the expected failure rate to the buyer so the buyer would be aware that he need to buy more and to test them first. They will continue this practice until more shops …

Problem solved. I made that arduino sram tester and modified the program so it do full random fill then read it back then AA55ing the whole sram again and read it back again. Weeded out 4 of the 10 chips, 40% defects! Now running only with 128K only so I downgraded the ram to 16MB for now so it's …

I found that https://github.com/johnzl-777/SRAM-Read-Write It append I did have an Arduino Mega 2560. So I should be able to test the sram chip soon without that tl866. It won't tell me if there on spec with regard to latency but I will be able to know if it alive or dead.

I don't have a TL-866 II (Yet... I did plan to get one) So from what you say it could just be bad chips, thanks.

I did some test I took from https://www.vogons.org/viewtopic.php?f=46&t=80308&p=949726&hilit=486%20l2%20detect%20detected#p949726 The different lines between the chips in same bank and different bank that should be parallel are parallel. Voltage for all the chips is 5.03v. Could not test down to the …

Hi there! I got some cache chip from aliexpress (32K * 8) to add 256K worth of L2 on my 486 but I can't get it to detect it. Board is not much documented, it have jumper for selecting 128k or 256k. But I could not find any other jumper to set (like to turn it on) and there is no option for that in …

Hi there. I did get a 486 PC not so long ago and I just noticed an issue with the BUS clock, not sure if it's normal or if I have to look at something to fix it. The CPU is a TI486DX2-66. Normally, in IDLE, the bus stay at ~33.2Mhz. But I did notice that during light load (Like playing a midi file …
