1. 115200bps in Timex FDD 3000?

Hi!

I've just got the PDF of WD2123 datasheet and I see
it can work at 115200bps, and even 153600 albo 307200!

Of course without interrupts it will be hard to catch
such transfer. Interrupts are on pins 22 (A) and 39
(B) and must be inverted before connected to Z80.
And you need screened RS232 cable...

Why didn't I have the datasheet before 1993?

See you,

Problably because you never though on that.
Who would imagine that Timex had put such a feature on FDD?
