Whoohoo! Finally, I will get to play with my HP A700 again! After it mouldering in my "oop north" shed for a couple of years, the A700 is to be reunited with me "dahn saahf". Question is, what - if anything - can I do with it? I don't mind if it's just messing around with some assembler/interpreted basic/etc., but I haven't the first clue about what's installed on it or anything. All I can tell you is it has 1024KB of memory... I no longer have any HP terminals, and none of the 3 I did have worked in any particularly meaningful way - the closest I got was a bootup screen, which can be seen here: http://www.classic-micros.co.uk/hp1000/r1024x768/A700BootScreen.JPG Or even bigger, here: http://www.classic-micros.co.uk/hp1000/r1600x1200/A700BootScreen.JPG However, nothing worked on the keyboard, so I couldn't get any further testing. So, does anyone have any clues as to what I need to do to get the beast talking? Inside the top cabinet, we have this view: http://www.classic-micros.co.uk/hp1000/r1024x768/A700TopOpen.JPG Bigger version (1600x1200) here: http://www.classic-micros.co.uk/hp1000/r1600x1200/A700TopOpen.JPG At the very bottom, you can see the serial comms cable coming out of the floor (the machine is in the lower portion of the cab), which comes round to the front of the serial panel next to the "0" connector. Connected to the "0" connector was the HP terminal pictured in the boot screen. I don't recall getting any life at all out of the other connectors. I will be able to post exact part numbers next week, but if anyone has any idea how a DB25 connector should be wired to allow a dumb terminal (probably AbsoluteTelnet on my PC) to talk to it? Should I optoisolate my PC from the HP - I wouldn't want to fry either of them, but my PC in particular, as I need it every day, sadly). Other pix (all of which have been seen here before) can be viewed here: http://www.classic-micros.co.uk/hp1000 This includes 2 HP1000F series machines, one of which I hope will join the A700 in the fairly near future.
