People fixing SSD drives for retro systems are silly?
Why because, those operating systems are not for SSD units, no trim, no delayed writing etc. their lifespan shortens. But, if you say that, 60 GB is too tiny to use for today's new operating systems, well then. Another fact is that, a good old Pata 40GB Seagate Barracuda 7200.7 for example, is really fast, no complications, much better support by software. You can use DiscWizard and can partition 2GB units more than 4. Like C, D, E, F, + disk sizes, 32 GB jumper can be used as well for 60+ GB drives to left drive letters for CD & DVD Rom drives and Ram disk. Maximum capacity is 750 GB with Seagate 7200.10 series if 48 bit LBA is supported by the controller. You can find many HDD utilities, but with a SSD they will? Unknown behavior. To install a SSD hassle free, you need to install Windows 7 for true support for SSD drives. Because of Slot 1 & Socket 370 systems can not complete Windows 7 updates after install, it is not possible for Pentium III systems good for SSD drive support.
For a BX chipset, only Gigabyte can adjust fsb 133 with 33 fsb bus, those two are Gigabyte GA‑BX2000+ and Gigabyte GA‑BX2000 as far as I know. Long periods of use with 89 fsb is too much to be stay at safe limits.
16 MHz signal can be boosted upto 20 MHz safely, this is the difference between 32 bit 16 MHz EISA bus to IBM 32 bit 20 MHz MCA (micro channel architecture) the percentage is 1,25 a 89 MHz is over from it, 1,33 times. I personally increased my Pentium 83 MHz overdrive to 90 MHz speed with the help of 16 MHz to 17,5 MHz oscillator replacement. I did not push it harder to 24 MHz to achieve 100 MHz because of the onboard IC regulator, not to be blown up!
Why do you need 133 fsb? Because of speed or being a fanatic of Pentium III? For old operating systems they need AGP cards because of driver issue. An AGP card can be plugged on a 478 pin processor based mainboard as well. They optionally use double channel ram and many more GB. Before they become retro and really expensive, try to obtain a good old 478 pin mainboard if you need more speed. They have SSE2 instructions as well, todays browsers strictly need SSE2 minimum! I have managed to find a Tualatin Pentium ııı/S 1400 MHz Intel 815E mainboard, but the memory limit is 512 MB maximum. Add on Highpoint, Adaptec, Silicon Image cards can not boot as an external controller, many pentium 3 mainboards are bad at that point. Pentium 4 mainboards do not have this issue. You may even have a HT processor on them, either SD-Ram, Rambus Ram and DDR ram are good with them. Nearly all Pentium 4 mainboards have onboard sound and ethernet cards, not necessary to buy extra PCI cards for Pentium 3 mainboards to add these. I have a Pentium 4 2400 MHz 512 kb cache 400 fsb Northwood processor on Asus P4T533-C mainboard. I have pushed it to 533 fsb and managed to run it at 3200 MHz stable after applying 1,65 Volts instead of 1.5 Volts. Pentium 4 2000 does not need even Voltage increase for 2666 MHz likewise. So you do not need to stick on Pentium 3 variant. If an ISA card is needed they are really hard to find and expensive. Do not waste your money for them, ISA cards are totally obsolete.
