Hey,
I'm undertaking a project in college to build a Motorolla 68k system. Because of this, I've recently become interested in constructing IC circuits (TTL) . Now, I need a power supply to do so. Will a 1-15V variable 2.5A dc power supply be sufficient or do I need an AC supply?
Also, digital electronics aside, am I missing out a great deal by not having an AC supply?

I too am missing something.
A 68k system will need 5 volts, TTL circuits needs 5 volts.
OK, where are you going to connect an AC power supply ???
If you need one, get it. Other wise wait till you need one !

I assume you are designing TTL circuits into you project not actually construction a TTL circuit
Why would you need a AC supply? Again assuming you mean a supply that puts out a variable source of AC voltage.

If you need to ask this, I don't have much faith in your project's prospects.

only having to rectify and filter it to get a DC supply
About all AC is good for is driving transformers (and powering AC devices)

Hay. Well, like the others said, but you actually want a 5VDC supply. The current you need is going to depend on how much you put into this project. A
5V only supply will have less possible causes of errors than a variable supply. It should plug into your mains supply and give that (5V) output. If you think you'll have other things powered off it (say, analog circuitry) you might want a supply with +/- 12VDC out as well, or maybe a variable output as well as the 5V.Examples:
A search on the different types of supplies may be instructive.
Cheers.
