<\/a><\/p>\nSuper Wrinkle, if I recall, was the ultimate boot loader – a worthy successor to the famous Wrinkle loader. Super Wrinkle required the minimum possible switch toggling to be read from the tape reader. Once it overwrote the toggled instructions, it read a more complex, generic, non-hacky loader. This had to be done after any power cycle \/ reset \/ program failure \/ hardware glitch.<\/p>\n
The alternative to toggling in the instructions to read an infinite number of (Super Wrinkle) bytes from the tape reader was too expensive for everyday computer use. We’re talking $27 for a mighty, 256 byte ROM chip. That was back when $27 was $27, mind you. One customer built such a device out of discrete diodes to save the cost. The word was it was quite a monstrosity.<\/p>\n","protected":false},"excerpt":{"rendered":"
