I think I may have fairies of some sort living in my 486 PSU... Recently bought this 486 and have done it up, with SOund card and CF + gotek driver. Loving it, apart from... when I first received it there was sound coming from somewhere. like a HDD loading or I dunno... like the LED flicker that …

You seem to have confusing sources. The board in that computer only provides a single bank of cache. The cache sockets have 28 pins. The biggest cache chips that fit into 28-pin sockets are 32kx8 chips. There are 64kx8 and 128kx8 chips, but they come in 32-pin cases, not 28-pin cases. A single bank …

Got it working. Used the win 7 VM WAY... TOOK ALOT OF TOYING WITH TO GET THE USB TO WORK THEN USB CONTROLLER DRIVER ISSUES BUT FINALLY. PLUG AND FINS. CF, transfer large files and off it goes in Dos pc

I haven't dealt with this issue myself but I believe that the fact that you're using OnTrack is your problem. See https://www.vogons.org/viewtopic.php?t=58192 Another option is to use an XT-IDE bios so you don't need drive overlay software, much info to be found on Vogons. CAn someone please please …

Thanks! I was hoping there was a way to do this without having to spend more money or time looking at the XT IDE route. Is there no other software that works do use on a floppy boot for overal? p.s thanks for support and time

P.S When I boot to DOS after On track disk amanger it has a loading HIMEM test thing going on and a sound (dont think its PC speaker) comes out as if its loading or singing me a song?!?!?!?! Same when playing games little beeps etc... again not speaker.. sounds like PSU has a speaker actually... …

Hi, As per my previous post, I got a old 486 to basically feel like a kid again and show my daughters some classic PC gaming! (I really don't think their care). I manged to get a Gotek drive in it for getting DOS etc on a CF card, have PC running fine with the 2 gigs and DOS loaded. Trouble I'm …

Sorry working link here https://www.ebay.co.uk/itm/2-x-M5M5256DP-70LL … 4.m46890.l49292

Hi, just to. Check. Is this the L2 cache I need, 6 off as I have 6 slots k/itm/2-x-M5M5256DP-70LL-Mitsubishi-SRAM-28-pin-32Kx8-NEW-PARTS-UKINSTOCK-2-CHIPS-/224370258883?_trksid=p2349624.m46890.l49292

So, got machine. It has 1mb vesa onboard CL gfx card, it has a 486 66, seems jumpers were set wrong to 50.. Most tests showing 486 50 but changed as per manual and now syschk shows 486 66. Topbench some reason gets very low scare and shows system as a 386 with a 212kb gfx card? It also crashes on …

Would this work for L2 cache? 6 of them? https://www.ebay.co.uk/itm/222523693019

Cant find the l2 cache ram. M I searching the right codes from above? One thing I don't get is for example to me 44256 is 256kb.. So if I had 8 that's 2.mb? Why is it people say 8, 44256 is 1mb.. How does it work out

Thanks for such a informative response. Great stuff. So I can add 128kbl2 cache only with 6x 32kb x8 chips? What spec or serial numbers do I look for? You mention 8 sticks of 1mb but photo is showing 4x sticks.. Which I assume are 2mb 30 pinn simms? The other four slots I assumed would need 2mb so …

Sorry one. Last thing, also not clear on Dram to get, I understand its 30pin, 70ns FPB simms is that what I search for because I can't find any.

Hi All, I bought a old 486 on ebay (yet to arrive) and with excitement of living child hood memories I'm already reading and digging out info on the hardware.. I've read lots on here (hence I found site) and even found the motherboard manual.. But after spending too many nights reading the we and …
