Are there any particular questions about the G800 you want to know? I used one in the 90’s briefly (less than a year). I traded it the minute the Zip disc G1000 came out, the only time I haven’t used a Roland for at least a decade before upgrading - the speed of loading presets became instant with the Zip disc, took too long live with the floppy on the G800!

Another major improvement between the 800 and the 1000 was the change from the basic Sound Canvas engine for the 800 to the Super Canvas engine with the 1000. Especially an improved acoustic piano… better effects etc.
