Ancient socket 7 pentium based tower

[MadEye2]

!!!

I had completely forgotten about mice using the serial port. I remember reading an article years ago on how to convert a PC serial mouse for use on an Amiga.
Thanks for the reminder. Theres a pin out diagram on Hardware Book for PS/2 to D-SUB conversion. I think I still have a DIN based keyboard somewhere too.
All I need now is a copy of Windows 3.1 and a small hard disk

The one I still have, but set aside at present, was in fairly regular use up to about 18 months ago, with Windows 98se running on it in 64 MB's of RAM. I wouldn't wish any version of Windows before W95, other than WfWg 3.11, on a friend, just on an enemy. I had drives as large as 20 Gb running on that old system. The last time I checked, there still are adapters for modern keyboards with PS/2 plugs, for use on large DIN jacks.

My first PC came with 64MB of RAM and with 98SE. It ran pretty well really and I may install it on this one. I still haven't identified what mobo this is and I guess I won't know until I install an OS on it. I just hope it can use more than 32MB of RAM. I thought I had found the correct manual for it or a revision close to it, but, although it uses some of the same chips the one in the manual and has a very similar layout, it has 2 DIMM sockets and PS/2 connectors.

I really want to try Windows3.x, I haven't used it since high school and I'm feeling a bit nostalgic.

I have no idea where that AT keyboard has disappeared to, and I have no idea where I got it from in the first place or even if it works.

Yea, just pick up a AT -> PS2 keyboard adaptor (eg http://www.dse.co.nz/cgi-bin/d...front/en/product/X8222 )

super 7 is a bit differant than a just plain socket 7. Intel abandoned the socket 7 after the 233mhz pentium, while AMD continued using it, with a higher FSB used by the K6-2 and called it super 7, so a plain socket 7 board, wouldn't work with a k6-2.

Not necessarily true 🙂

If the motherboard can do 2.2Vcore (or 2.3 or 2.4, really), you could drop in a K6-2/400 or faster, set it to 2x multiplier, and get 6x66=400MHz, thanks to the CXT core's multiplier remap 😀

BTW, not all K6-2s were 100MHz FSB...

Originally posted by: KiwiI have a PC here that has no PS/2 mouse port, and the old style large DIN for the keyboard, not a PS/2 keyboard port (it's a P-I/233 Socket 7 job, with three PCI slots, AGP, two ISA slots, and four PC-66/PC-100 168 pin RAM slots). The case it's in has some odd features compared to newer ones, also.

You sure about that AGP slot? That's a part of the Super Socket 7 spec, not the regular Socket 7. You could certainly run a 233 (or even slower) on a SS7 board, though 😉

That one was my first AGP- equipped PC, new in 1999 (1998?), and has an Intel MB in it. It had an ATI "Rage Pro" 32 MB card. Probably AGP-1, the one with the "wrong" too-high voltage for the 2X and subsequent AGP's. And, I misquoted the number of PCI slots, when writing about it. I was just scanning some notes about a replacement system I assembled last summer and saw mention of FOUR PCI slots, but one of those shared a backplane opening with the nearby ISA slot.

The P55C version of the Pentium I differed from the ones before it, none which had included MMX. In its own way, it was "Super".

I got my first PC in 2000. It had an onboard AGP chip - Trident Blade 64 or something, it was utter crap.

I'm going to have to find the manual for my board to find out what voltages it can use. I'd love to get another crappy K6-2 on this thing

I may have to buy another ps/2 keyboard and adaptor - I can't find the AT one

Aye, I wish I knew where the local tip was. Schools are a good place to find old parts - my dad did some electrical work for some highschools and was given a load of old PC stuff because they didn't know what to do with it. I can't very well hang around outside schools now though, they'll think i'm up to no good.

Theres a small computer shop in town that sells refurbished PCs for ridiculously high prices - £150 for a P2-400 based base unit! I might sneak round the back of the shop and see if he's thrown anything out.

I found this while searching for the BIOS ID. I think it's the right board, but this one says it has a PS/2 mouse connector and 2 USBs. It'll be one that slips into a bay with a cable running to the mobo won't it? If so I don't know why it would be missing as there doesn't seem to be a reason for the original owners to take it.

Presuming my mobo can do a 2.2v core setting, will running a K6-500 chip at 2.5*66 enable it to run at 500? Or does the CXT core only work with a 2x multiplier?
