Hello all, I found Intel Premiere/PCI II BABY-AT (Plato) motherboard in a pretty good condition (except of dead Dallas, ofc). One thing to clarify before I hit a button - what is the maximum CPU it can support? According to its manual there are only 75, 90 & 100 MHz Pentiums. Is there any chance to …

Yes, it works just fine with Pentium II 400 MHz. I assume it will work with Pentium III too. Filename 20230820_183544.jpg File size 358.97 KiB Views 651 views

No, +5v to PCI. There is only 4.12-4.19v, but on other board - 4.93-4.95v.

Hi, I accidentially learned that my Lucky Star 5I-VX2B motherboard missing 5v - I measured only 4.12-4.19 on PCI 5v pins. I suspect that's the reason that my Intel PRO/100 Management adapter isn't working on particular this board, but works just fine on other boards (486, SE440BX, WS440FX). All …

Hi guys, same issue for me - my Pentium II 400 MHz came today without fan cable. Quick search gave me this one: 3-Pin Fan Connector to 3-Pin Motherboard Cable / Cord, PC-011. Will it fit? Filename s-l500.jpg File size 9.5 KiB Views 814 views

Hi all, I have a good offer for that 286 board (see attach). Board is in the pretty good working conditions - at least BIOS is functional. The question is - which manufacturer? Anybody familiar with that board? Unfortunately, I didn't find any similar on the retroweb. Also I can't see a battery …

Or G-LINK GLT725608-15T? Near miss again. This time the electrical paramaters are fine, but the DIP variant is 600 mil (0.6 inch) wide, which is as wide as a BIOS chip or keyboard controller. Cache sockets require 300 mil wide chips (like standard logic chips). Sometimes the 300 mil variation is …

16Kx8 chips were introduced quite late. 32Kx8 chips are considerably more common. Most 386 boards that use a single 8-bit TAG RAM are designed to take a 32Kx8 TAG RAM, and will just use half of the RAM. So any 32Kx8 chip most likely works fine in that board, too. Those common chips usuallly have …

For a 386 or 486 ISA/VLB board 20nS tag is just fine for 33Mhz FSB, from my experience a 15 nS would be better for a 40Mhz FSB if you have options to tweak the cache/memory timings...just an opinion ;p What speed are you current main cache chips ? Chips are UM61256FK-15 (15 ns, I guess?). CPU is …

As far as I understand, W24129A serie is a 16Kx8K chips with various timings (mine is 12 ns). What is an alternative for it? Found Micron MT5C6408 but this is 15 ns. …
