I'm a newbie to the TI/99 and have a few questions about the Peripheral Expansion System. I'm very curious and Hopefully this isn't too much at once
1. Back when the TI-99 was current generation, what was the purpose and usefulness of the Peripheral Expansion System? Would it allow the TI/99 to have functionality that was otherwise impossible, or did it just eliminate the need for sidecars and stand alone peripherals?
2. Was there any software that required more than one sidecar expansion, or was it a case of the TI/99 being discontinued before the Peripheral Expansion System had any purpose other than convenience and aesthetics.
3. In the present, is there anything the Peripheral Expansion System does that can't be replicated by modern homebrew add-ons or is it something mainly used only by collectors and people who prefer using original hardware as much as possible?
