I believe what Steve is requesting will be slated for future production. Why bother producing units with 64K EPROMS when we will just have to upgrade them to 128K EPROMS in the future. Could you please produce a 128K EPROM firmware set of version PC 1.94w AE for use in new production only. We will still need future 1.94 versions in 64K EPROMS for previously sold machines for those customers that aren't willing to pay an upgrade fee.
We may also need other current versions of firmware (e.g., CP, 1.94f!, ...).
Thank you
Ian

Or will we need to maintain a supply of 32K EPROM's and 28 pin clock chips to support those users who do not wish to upgrade?

> Yes, V2 of the Precinct Count firmware will require 2 128K EPROMs. Yes it would be possible to download pre-V2 firmware versions onto 128K EPROMs (in fact 1.94 would fit on a single 128K EPROM). No we won't need a supply of 28 pin clock chip sockets because the 32 pin versions will support both the 64K and the 128K EPROMs. However, I expect that we will have a surplus of 64K EPROMs and 28 pin clock chip sockets resulting from field upgrades so we will likely use those in cases where we don't need the larger chips.
