What is the 36 Sector per Track option and what does it do?
The Myarc HFDC can be upgraded so it supports 36 sectors per track which means it can host 1.44mb, 3.5″ floppies. Before you get to excited there is one major constraint; this will only work with Geneve based systems. It is important understand this upgrade even though it does not expand the TI-99/4a. I stumbled across the mentioning of the upgrade and spent some time trying to figure it out and even though it won’t help me it will help other avoid having to search for this information. The upgrade option is as follows: • If you have an FDC9216 in U16 then it is replaced with a FDC9216B. • If you have an 8k memory chip on the card (6264) then it is replaced with a 32K chip (62256).
