@r0jaws: Having recently acquired an A2000 myself (unexpanded, 3.1 ROMS and CD-ROM), it's been very interesting to follow your ongoing adventures with yours.
I've a Buddha Flash coming in the mail to get a HD installed and the CD-ROM connected. At some point I hope to get some kind of accelerator, an RTG card and more RAM into it.
Before anything, I have to open it up and dismantle it to see the battery, etc. Is that replacement coin battery that you installed into yours, rechargeable?
