XT-IDE rev 4B Prototypes Are In!

I already drilled speed holes in it though!

Aw, Man! I thought those were dive brakes like the ones on the Douglas SBD "Dauntless"

I doubt you are planning on in-circuit flash/reflash, but if you are, keep in mind the preambles need to be written at offsets beyond 16KB. JR-IDE is reflashable in-circuit, but only because I can pan an additional 16KB page frame around the entire 512KB part.

I'll probably use the SST 39SF family, which is 4K block erase/write and does not require the entire device to be erased. I'm using it for both the boot ROM and the CP/M A: drive on the 8085 SBC rev 4, fairly painless even on an 8-bit processor!
