Troubles with Mining

I'm having troubles getting my mining farm working.
First, the computer I bought yesterday from Luther College doesn't work with my monitor. When I was using desktops (about 5 or 6 years ago) they all used VGA monitors. I only have 1 VGA monitor and the cards I bought on Ebay and the Luther computer don't work with VGA.
I don't even know what they are using; I'll have to do a bunch of Google searches and see if I can figure it out.
I'm too broke to buy anything on Ebay to get things working.
I do have 4 computers working so that's a start.
One guy wants to sell me a couple of desktops for $15 or $20 and they sound really good. I just don't have the money right now. I offered to trade him a silver coin but I haven't heard back from him
Steemit, on the other hand, has turned out to be a money maker. I'm already up by $1.97. That was from 1 posting of my normal blog. I've been on Blogspot for at least 6 years and I'm only up $10 for the whole 6 years. I should have gotten on Steemit earlier.
I got my forms for taxes from Etrade last night. Now I can file income taxes. I should get a nice return.
I used the free tax program from Credit Karma last year.
I'll do it again today. I need the money for mining crypto.
I also listed one of my etching (by Malcolm Childers) on Ebay. I'm asking $500 for it and another seller is asking $2800. Maybe it will move.
