I have finally got hold of a Tatung Einstein Hardware Reference Manual. A physical copy!!
Its huge! – 12 inches tall by 8.5 inches wide and about 100 pages.
As with many books from old book shops, there is a musty smell to it, but I have to say, this looks to have been lying around for a long time. It needs a damn good airing.
I never had this in the late 80s when I originally owned an Einstein, so this is a revelation! Sure, I have read it online in PDF format, but there is nothing like having the printed matter in front of you for reference.
This should allow me to tinker properly and diagnose why my Einstein is poorly!
