Ja, a laptop would work. Even better, cheaper, why not use a good old desktop coputer? Then you could just have the components you need, IE a motherboard, a removeable video card, sound card, the amount of memory you like, etc. Best of all, the (...)

Sure it can, provided: -you can get the voltage output to be in a respectable range for the HDD (solved by changing battery power to output chips) -you can write a driver using the necessary digital inputs/outputs as necessary (hard but (...)

I had the same problem. I tried everything, even replacing the CMOS memory chip, to no avail. Since my board was purchased assembled from Gleason, I ultimately swapped them for a replacement which has been working perfectly. I don't know whether (...)

Hi. Have any of you guys out there had experienced getting a MEMORY FAULT message from the HB or getting garbled displays ? I really hope someone could tell me what this means and what should I do about it. Thanks in advance. F. Samonte (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

(...) Yes it can. (...) Well, without modification, the parallel port can probably do a lot of what you need, although, there are only 8 (12) bits for you to use. A separate processor could communicate through a serial port, and do some of the same (...) (26 years ago, 10-Mar-99, to lugnet.robotics.handyboard)

Great ! I thought no one could have done or imagined something like. The problem, I belive, is that no massive memory storage device (massive: about 1Mb or 2, or 512 KB ...) has an input that can be interfaced with the handyboard or with another (...)
