(Sorry for dropping part of text earlier!) The horizontal sweep on my 7300/unix_pc/3B1 has begun to show signs of failure (characters appear progressively narrower to the right, and column 1 is edging to the left. Is anyone on the net able to offer experience on what to expect next and how soon and how to refurbish it before it is too late? This machine "bonasa" was delivered as a 1x20 7300 in 1985, and has been on the air virtually continuously ever since then, except for a couple of office moves and upgrades to 2x40 and 3.51m. My Terminal Reference Manual does not include schematics for the monitor. Can anyone advise me if there are discrete components, such as coupling capacitors, that are the likely culprits and can be replaced? And can anyone offer a schematic of the monitor? Many thanks. -- Randy Randolph S.
