Ok i just recived 5 VERY old IBM computers for free to do what ever i want with. Well as i said there old, they use Socket 7 with an Intel of some kind not sure what kind it is. and it has slots that im not familiar with but im sure you guys are familiar with. There rather long and black, plus it has memory sticks i haven't seen before which means that parts are no longer made for it but it does have a slot im used to seeing. Also the PSU is very old and strange, it dont connect like most that ive seen before.

Any ideas as to what i can do about a more powerfull PSU? Because i plan on adding a few HDD's to it and a new CD drive and some other stuff.

Socket 7 will be a Pentium since the Pentium 2 migrated to slot 1. Your motherboard will be an AT form factor and therefore you'd be hard pressed to find another PSU, however hard drives and other such periphirals use the standard 4 pin molex connectors therefore you could just use a spare ATX PSU to power that junk, and use the AT PSU for the board itself.

Those slots are ISA (Industry Standard Architecture) which are 16 bit variants of the newer PCI slot. They obviously have smaller bandwidth but served the same purpose for devices such as modems, sound cards etc.

Im just curious as to how hard it would be to find a PSU for this and some new memory, each bank supports 32mb and each bank takes 2 slots. So thats 16mb per slot, and it currently has a total of 32mb. But i will have to find a new PSU or do some modding to another one to work on this thing. Because the 12V rail has only 5 amps rofl.
