Upgrade from a IIe to ehnanced IIe requirs mere replacement of several chips -- character generator ROM (for mouse text), CD, EF ROM (for new 80-column text firmware; old version contains some annoying bugs) and a new CPU (65C02). But if you're talking about from a Rev.A board, that's a whole different ball game...

I think what you mean is that a Revision A motherboard would require the swap--for a Revision B (which most IIe's are), you just need to buy the IIe Enhancement Kit (around $50 mail order). It includes the 65C02, the CD and EF ROMs, and the MouseText video ROM. It comes with a chip puller, so you can do the installation yourself. If you're not accustomed to removing and installing chips, your Apple dealer will do it for you (or should :-) >|UUCP: humu!nctams1!pnet16!tomj >|ARPA: humu!nctams1!pnet16!tomj@nosc.mil >|INET: tomj@pnet16.cts.com > >-------------------------------- "We were having a great time, but >!

All that needs replacing is the 6502 with a 65c02, the Video ROM, and the CD & EF ROMs. This can be had two ways; 1) Programs Plus sells the complete enhancement kit for $49. or 2) get a 65c02 yourself and burn the ROMs. But we can't talk about that.

I need a memory refresh :-) does the old Rev. A have DHR capability? My
sister has the IIe, and I believe I did some DHR graphics on the thing.
When I get my new modem for my IIgs, she'll need an enhanced //e to run
ProTERM. (She'll get my old DataLink 2400.)

Yea, If you geA+ magazine then inside you can purchase a kit to enhance
your }{e... There's instructions with the kit on what chip your are
