OK, no jokes about 'crashes' here. Investment Monitor isn't a get-rich-quick method to decide what shares to buy, but a useful method of recording your equities, gilts, unit trusts, bonds, regular investments, and probably what you've stashed in a sock under the bed too.
Epson and RS-232 printer convertible, Investment Monitor is basically a menu-driven card-index system. Each 'card' is tailored to take details of the particular kind of investment represented, including date bought, value, current price, dividends, and so on.
You can review your cards singly or in numerical order, and update, delete, insert or renumber them.
Also, should the stockmarket collapse, your Spectrum will jump out of the window for you (not strictly true - Ed).
