"It's pointless giving hobbyists more than 1k, they wouldn't know what to do with it".*
- Andrew Hewson in a magazine (Sinclair User?) column, on the release of the first ZX80 RAM pack.
Hewson later went on to form Hewson Consultants, which became a moderately successful 8-bit games company thanks to some of those hobbyists. They not only knew what to do with it but also sent him the proof to populate his company's catalogue.
*Probably a paraphrase. It's pushing 40 years since I read it.
