Nor am I writing this in a professional capacity(necessary disclaimer). But, here are a few things that I have learned. The escape sequences for dealing with the micro-p inside the HP2645 all start with &c <16-bit octal number>a sets the address for the next transaction <8-bit octal number>d deposits a byte at the current address. E transfers program counter to current address As always, the last (and only the last) character in the escape sequence should be a capital letter. There are other commands but I have forgotten them. There are also sequences for 262x terminals. A short (and useless) example follows. As always means character 27(033)! &c170360a311d000d000d000d212d117d123d234d145d167d201d320d000d000D &c170366aE Happy hunting! PS. If enough interest is shown, I might be able to dig up my HP2645 games(road race, cat&mouse, space invaders). I didn't write these, they have been floating around for ages. -- Jim Davis (James W Davis) ...!ucbvax!hplabs!davis davis.HP-Labs@Rand-Relay ----------------------------------------------------------------
