I have another PC - a refurbed NEC Ready. The model that NEC gives it is RB 248. It is a Pentium II 350. Nice system and works well.
Lately I have been looking into upgrades for this system's processor, and have been a little stymied because I would like to get a large speed increase and I am not sure about compatibility.
The NEC site info says:
This motherboard utilizes the SEC slot (SLOT1), which is a staggered 242 pin Single Edge Contact slot. BIOS Intel® E28F002BXT80 2 MBit Flash EPROM
System BIOS by Phoenix
Bus PCI/ISA based system bus (PCI 2.1 compliant)
100MHz maximum bus speed
Chipset Intel® 82440BX PCI AGP Controller (PAC)
Intel® 82371EB PCI chipset (PllX4E)
This motherboard supports the following CPUs:
Celeron 266/66, 300/66
Mendicino 300/66, 333/66
Pentium™II 233/66, 266/66, 300/66
Deschutes 266/66, 333/66, 350/100, 400/100
Pentium™III 450/100, 500/100

It seems as though (from posts I have read on Anandtech forums) I can use a "SLOCKET" (e.g. Microstar MS-6905 Master Slocket), a cooling fan - "Golden Orb", and then one of the new Celeron II's (533a) to get a low-cost (about $140), overclocked, 800Mhz upgrade.

I haven't seen many posts on this type of question, so let me know if I should be posting elsewhere.
Thanks.
