Lifepower asked me in another thread about some of the programs I've worked on, so instead of hijacking that thread, I thought I'd put it in as a sort of introductory post in this forum, who's sticky post at the top indicates it's the right place :-)

ISAM (early 1980's)
General Accounting (Debtors, Creditors, General Ledger, Stock Control)

DBF based (1980's)
Wages & Salaries package
Voter Registration & Logging

other (1980's)
Breakout (game)
Pinball (game)

SQL based (1990's)
Records Management
Vehicle Service & Maintenance

SQL based (2000's)
Vehicle routing
Service Contract Management & Debtors
Debtors System (aka Accounts Receivables) - derived & extended from above
Liquor Sales & Inventory Management

I've not worked on any other major systems since around early 2009, ie, the last 4 years since which I've been Technical Director for a company of 18 staff.
