None that I know of, and there are many advantages. I've been using an
enhanced IIe for about 5 years now, and I'm a big DOS 3.3 user.

There isn't really any "patching" involved. Just like your present setup,
no matter what you do, Applesoft will only have 33K of RAM to access. The
big RAM cards come with RAMdisk drivers for big RAMdisks. Well-dome
programs like ProTERM and Appleworks 3-5 automatically find and use the
extra RAM.

Depends on what RamWorks card you get, I think. My IIe's RamWorks III
takes up to 1MB and has pins for more RAM on a piggyback board. The
piggyback board can accommodate 512K-2MB. I have the whole nine yards for
a total of 3MB on my RamWorks III. It can be pretty handy when working
with really huge Appleworks DB's, and there are times when a 1MB ProTERM
scrollback buffer is very useful.
>2b)Would a RAMworks card conflict with a FAMfast SCSI card?
Dunno. Don't see why it would. I've used mine with both the old style and
high-speed Apple SCSI cards with no problems.

As far as I know, the 8-bit ZipChip only comes in one size these days, the
8mhz one. I thought it had an 8K cache, but I might be wrong. Get as big
a one as you can afford. I've not used the ZipChip, but I have used the
3.6mhz/128K cache TransWarp I and 7mhz/8K cache TransWarp II, and the two
cards are about the same subjective speed: FAST!

A gate array is a custom chip, commonly used to save space on the circuit
board. You don't need to know anything about them to use a Zip.
4)What is the maximum (hard) disk space a ][e can use (like the GS's

ProDOS can recognize up to (I think) 8 32MB drive volumes. It is easy to
partition a large drive into multiple partitions that look like separate
drives to ProDOS. At one time I had two 5.25's, two 3.5's, a 20MB hard
drive, and a 40MB hard drive partitioned into two 20MB volumes. ProDOS
thought I had seven drives, and it all worked swell.
Note that to access this many drives, your IIe MUST be enhanced and using
ProDOS 2.x. It is this version of ProDOS that has the ability to map extra
partitions into other slots; if I remember correctly, older versions just
don't see the extra partitions if there are more than two on the slot.

Nope. All you need is ProDOS 2.x. However, ProSel is a GREAT disk utility
and well worth having. For example, one utility can hunt down marginal
blocks on your hard drive and put them in a "BAD" file (there are almost
always a few). And its recovery utility is the best there is.
>4b)If DOS 3.3 is limited to 5.25 disks, does that mean I'll be unable to

There are programs that let you put DOS disks on a hard drive; I've found
it more worthwhile to use actual 5.25 drives, myself. And I use ShrinkIt
do make backups of my 5.25's to 3.5's and the hard drive.

A IIe should easily be able to handle a 14.4 modem. You don't lose as much
as you may think at that speed, as most connections drop to 24K or 21K
anyway. I find that using my IIe and Lynx at 2400 is almost as fast as
using Netscape at 24K on my 486.

I don't see any advantage to the IIc+. Add-ons like large RAM cards are
hard to locate and expensive, and the IIc+ isn't NEARLY as fast as an 8mhz
Zip!!! And you have no slots! I don't find that a plus in ANY way!

You can use any old SCSI card. Alltech sells one for $39, I guess it would
work with the IIe. Any Apple SCSI card works just fine. If you get an
accelerator, you lose all the speed of the RamFast and the Apple
High-Speed card, because you have to turn DMA off. I ran tests on an old
Apple rev.B card, and on Apple's High-Speed card, and with accelerator
installed (and DMA turned off), the old SCSI card is actually faster.
Believe me, you =DO= want an accelerator!! My vote says save your money
on the fancy cards like the RamFast; the IIe doesn't get nearly the boost
that the GS does. And, believe me, you will be blown away by the SPEED of
even the slowest SCSI setup, compared to what you have now.
If you want to add a 3.5 drive, you can buy a complete Unidisk setup (card
and controller) or Laser Universal DIsk Controller setup (disk and
controller) for what people are selling just the Superdrive controller
card for. The Superdrive card is rare and still expensive. I have the
Laser card and two GS-compatible AMR drives on my IIe.

Good luck. You are gonna LOVE your rebuilt system!
