[vcf-midatlantic] Looking for a TI Silent 707 1200baud for the VCF Museum

Just tried dumping a text file to my 703 at 1200 baud and you're right, 
after about 500 characters or so, it can't keep up with the input. Is 
there any way to put a delay after characters / line on Simh? I tested 
again by dumping the same text file via TeraTerm using a 15ms delay per 
character and 350ms per line and it seemed to work fine.

Tricky bit might be the ROM as it's an 512x8 PROM (82S147) I've managed 
to image it though if anybody wants a copy.
