I have a nice HP 64000 series computer for sale. I rescued it from a surplus shop and fixed/cleaned it up a bit. I don't know much about it, and would like to pass it on to someone who does. Here is a copy of the post I left on the vintage-computer.com forums: For sale: An HP 64110A "portable mainframe" computer, used primarily for doing design work and in-circuit analysis and emulation. It's still considered to be a fairly competent diagnostic and development tool. Not to mention it looks awesome. This thing has been tested by me to the best of my ability and seems to be in full working order, but it's huge and I really am probably never going to use it to it's full potential. It comes with the optional "backpack" pouch attached to the top of the unit. It also comes with a large amount of cables and probes of various kinds. It has 5 different "pods" which can plug into the back of the unit. I am not familiar enough with this computer to be able to say what all the cards inside of it do. It also comes with a number of floppy disks, all of which work and have data on them. I am fairly sure some disks needed for doing compiling/text editing/terminal use are missing. However the boot disks and timing disks are there and work. If you know what you're looking for and can direct me, I'll be happy to do whatever inspections/photo taking you need. The machine does have a few small defects which I will list here: -The plastic screen cover has gotten a little bit discolored/foggy in one corner, which makes the screen look slightly blurry, but in my experience the screen is still very readable. -the keyboard hinge has come slightly loose on one side, but generally this is not a problem when operating on a table or in the "upright" mode standing on the floor -a couple of keys are slightly gummy in operation, and a good cleaning should fix this -there are some fairly normal scratches/scuffs on the case, probably because this thing is heavy and some engineer many years ago was forced to drag it across the floor. -and lastly, I haven't taken the time to thoroughly clean the thing, so it's fairly dusty inside I am looking for a some things I can get in trade for this beast: -A compact flash drive card for Apple II (CFFA, etc.) -Other Apple II things, especially IIgs stuff -Tandy model T things (ROMBO, NadsBox, TPDD 1 or 2) -Neo Geo MVS hardware (kinda a long shot, but hey) -what have you, just ask if I'm interested I would gladly trade this whole setup for a MicroDrive card for Apple IIgs. I accept PayPal if you aren't interested in trading. For people making offers, I am thinking somewhere in the price range of... a MicroDrive card. So $150? Let me know if you think I'm way off. One final thing- this beast is very heavy. You'll be paying shipping, which I have no clue how much it'd be because I'm not exactly sure how much this thing weighs. http://www.vintage-computer.com/vcforum/showthread.php?t=17278 http://picasaweb.google.com/arf.at.sjv/HP64110APortableMainframe# If interested, email me: arfink (at) stthomas.edu or send me a PM via the vintage-computer.com forums.
