We have a question about upgrading 3B1 boards. Are the boards that came with 0.5 meg socketed for the whole 1.5 meg? I can't just pull the board out of the machine in question because its about 3 hours away from here. I understand that all the support chips for the extra memory are there, so it would make sense that the sockets be there, too. Jeff Wieland wieland@ecn.purdue.edu

The EIA/RAM Combo Boards can all be populated to 1.5 MB no matter how they came populated. Make sure you have the documentation on the board available. Depending on what other boards you have in the machine, you may have to place the board in specific slots. Also, the jumpers on board must be adjusted based on how much RAM you're putting onboard. .5 MB RAM boards are RAM only and can not have any RAM added to them. Be cautious! Also in existance are Dual Serial Port boards. These are identical to the EIA/RAM Combo Boards with the two serial ports, but come with no RAM, and no sockets. It's been widely discussed that while these boards _may_ be able to be socketed for RAM, the amount of work necessary (as per lack of specific parts?) makes it something to just Not Be Considered.
