We discuss generation of series expansions for Ising spin-glasses with asymmetric $\pm J$ (i.e. bimodal) distribution on d-dimensional hypercubiclattices using linked-cluster methods. Simplifications for the bimodaldistribution allow us to go to higher order than for a general distribution. Wediscuss two types of problem, one classical and one quantum. The classicalproblem is that of the Ising spin glass in a longitudinal magnetic field, $h$,for which we obtain high temperature series expansions in variables$\tanh(J/T)$ and $\tanh(h/T)$. The quantum problem is a $T=0$ study of theIsing spin glass in a transverse magnetic field $h_T$ for which we obtain aperturbation theory in powers of $J/h_T$. These methods require (i) enumerationand counting of \textit{all} connected clusters that can be embedded in thelattice up to some order $n$, and (ii) an evaluation of the contribution ofeach cluster for the quantity being calculated, known as the weight. We discussa general method that takes the much smaller list (and count) of all nofree-end (NFE) clusters on a lattice up to some order $n$, and automaticallygenerates all other clusters and their counts up to the same order. The weightsfor finite clusters in both cases have a simple graphical interpretation thatallows us to proceed efficiently for a general configuration of the $\pm J$bonds, and at the end perform suitable disorder averaging. The order of ourcomputations is limited by the weight calculations for the high-temperatureexpansions of the classical model, while they are limited by graph counting forthe $T=0$ quantum system. Details of the calculational methods are presented.
