Information about the ASTEC UM1286 Modulator
Posted: Tue Jul 04, 2017 11:20 pm
I've been trying to find out information about the UM1286 modulator, specifically what each screw adjusts. Today I have finally found that information hidden inside the service manual for the Memotech MTX 500/512, no wonder it took me so long to find!
The manual can be found at http://www.primrosebank.net/computers/m ... anuals.htm - be sure to download 'MTX 500/512 Service Manual and Technical Information (5MB)' and not the larger size download. The relevant details, including how best to test and set the modulator, can be found on pages 42 and 43.
Does anyone know what 'cable compensators' do?
