Is your 453 a mod 703H?
Does anyone have a 453 mod 703H manual?
Does anyone know what was done for mod 703H?
The obvious is larger CRT, side controls moved to front and solid state vertical amplifiers from nuvistors.
Thanks
Glenn

If this isn't scanned already, I have the capability to scan it
(including foldouts).
The one on Tekwiki doesn't seem to mention serial number ranges, so
could be for earlier models?
My own 453 is a SN 34xxx (IBM logo).
