WTF are you talking about? Jack Tramiel gave us the B128 (128k of RAM) and the B256 (256k of RAM) in 1983.
The B256 which you famously refused to buy, saying "I want less memory!"
Why was the SID chip team only given a month to design the SID chip and what happened to them after the first month?
What happened to the original MOS team?
Why didn't Commodore fix the hardware in the 1541 making it faster?
What happened to the Commodore LCD prototype?
Why didn't Commodore invest in schools after the Commodore Pet?
Why were Ram expanders separate for the Commodore 64 and 128 instead of put on the computer?
Where was the Commodore hard drive? They never invested in one.
What happened to the Commodore light pen? It was never released.
What happened to the Commodore Midi keyboard? It was only released in the Netherlands.
The answer is that Commodore didn't invest in these avenues. Instead, Commodore lowered the price of the Commodore 64 every year decreasing profits.
If you were delivering newspapers with a car, you would have to reinvest a third of your profits into car maintenance. Commodore made someone rich at the top and the money didn't go back into the product and I would see their job as design and to get machines out the door which they didn't do. Instead, they were bleading money out of the company.
