P112 question - what can you run that uses 1MB of RAM?

AS I mentioend ewarlier, there was a VDO interface board abailable for the SX printer. The orinial/official one fitted in place of the formatter, it was just a simple set of buffers. The SX DC controller board has single-ended 'beam detect' and 'video' signals whic hare not really suitable tfor sending down the cable to/from the host. I am told the serial[1] control.status interface on the SX is upwards compatible with that on the CX, the former accepts a few more comamnds. I've never managed to get a list of the commands/status messages that are used on this interface, fortunately you can ignore it if you just want ot pritn from the nornmal paper tray, etc. [1] This is a synchronous interfce with a separae clock signal. It's not evenclose to RS232 . -tony
