Dear Jim In my short experience dealing with Mexico leads me to agree with Petri. Part of the issue is that local production is on a very small scale (even smaller than in Spain). So it is very hard to find things if you miss the first time around. Having said that, I've found "Marcial Pons" in Madrid at delivering stuff (as long as it is in their catalogue): http://www.marcialpons.es/ As for history of computing in Mexico, I think the 'Annals' printed a piece on this failed microcomputer. Tom Haigh and I are working on something (which is currently on his lap!). The only item I am aware of which is of some value is Cantarell, A. and Gonzalez, M. (2002) Historia de la computacion en Mexico (three volumes), Mexico DF: Hobbiton Ediciones SA If you then google "historia de la computacion en mexico" you get a number of websites at the National University and the Polytecnic. This is where it seems some body of knowledge is building up. As for university catalogues: (Public) Universidad Nacional Autónoma de México +catálogo general www.dgbiblio.unam.mx/ +Biblioteca Nacional de México http://132.248.77.3:8991/F +Biblioteca de las Americas http://www.cervantesvirtual.com/portal/bnm/pcuartonivel.jsp?nomportal=bnm&conten=catobras Instituto Politécnico Nacional, http://azul.bnct.ipn.mx/ (Private) Instituto Tecnológico Autónomo de México, http://hammurabi.itam.mx/F/-/?func=bor-info Universidad Iberoamericana, http://www.bib.uia.mx/sitio/ Others include: Universidad Panamericana, Universidad Anáhuac, Universidad Anáhuac del Sur, Universidad Metropolitana, and Mexico City and Monterrey campii of the Instituto Tecnológico y de Estudios Superiores de Monterrey.
