I would choose one with Intel BX chipset. You won't regret choosing it, unless you love to play with drivers, BIOS and chipset tunning :) They are just solid - rock stable and top performance. Build and work/play. Someone may say they're boring - not much to improve. For CPU - faster is better. P II …

ZIP memory chips should be 20 pin, that's for sure. Organization should be 256k x 4bit. Timing ? Chips onboard are 45ns. It is hard to find ZIP memory "that fast " Cirrus Logic mentions 70ns in specification (from here ) for 45MHz memory clock. I think we can asume 60ns for 50MHz MCLK (which is max …

Thanks for the links, I'll take a look. About the cache memory, the book says this: CACHE MEMORY 128 KB of second-level cache memory may be installed (except in the 486/25VL). All four chips must be installed. My model is 486/25VL, so it seems that the missing chips could be the ones needed for …

Now you have 512kB graphics memory: 4 chips in organization of 4 x 256bit v53c103 . I suppose you have to buy 4 ZIP chips of the same organization: ebay search You are right regarding cache sockets. For cache memory just buy 32kBx8 chips just like on the picture I linked before , but... I'm not sure …

According to your motherboard chipset datasheet VL82c480 your system is ISA only :( But CL-GD5428 is fast ISA graphics chipset and you can probably double its memory throughput supplying ZIP memory to empty sockets (between CPU and graphics chip). To even more boost system performance you can solder …

Check your BIOS chip (2MBit vs 4MBit). Maybe you can flash bigger BIOS on it ? If not, you can always buy chip with bigger capacity and try hotflash (with Uniflash - tried that many times with success).

I discovered that this PC Chips M930LMR has unofficial support for 533 MHz bus CPUs. In the CMOS settings the CPU PnP Setup menu allows you to set the memory and bus speed, but the choices are limited to 100/100, 100/133, 100/166, 133/100, and 133/133. I really wish it had a 133/166 setting, …

The above linked Lo-tech board will not work for you. Its for a XT and will not provide RAM above 1MB. You need a 16-bit RAM card like the Intel Above Board or the AST Rampge 286. But there are many others. Of course you board will accept a IDE-controller but should remove the MFM-controller if you …

You can probably use this expansion https://www.lo-tech.co.uk/wiki/Lo-tech_1MB_RAM_Board to provide upper memory (between 640KB and 1MB). Drivers and other TSRs could be loaded there (mouse driver, etc.).

Hello, I have this motherboard, HOT-661V31, and wondering if I can use a Pentium III 600E CPU on this motherboard. The manual says it only supports Pentium II and Celeron CPUs but since the chipset is 440BX, I may have a change to use a PIII CPU on it. The problem is that the manual jumper setting …

According to Unisound thread - cards based on AZt2320 probably can not be set up to use IRQ 7. Therefore I suggest AZT2316. For example Unreal from Future Crew doesn't play music on SoundBlaster compatibles with IRQ 5. Older titles may be more compatible with IRQ 7

There is file called 'dosstart.bat' inside c:\windows directory. Look into it. Also, please be more detailed about sound card - photo of main chip would be perfect.
