However, you do not need a 1750 to do so. The 1750 clones are overpriced ($199.95) and you can do the same thing at home if you know how to hold a soldering iron and how to be careful about being grounded (touching something metal or standing on a conductive surface). If interested, let me know or get the directions off of one of the mail servers. This basically involves buying a 1764 REU and adding a few memory chips to its innards. A more elaborate expansion adds up to 2 MEG in 256K increments. Stan
