Amiga 2000 Resurrection

Greetings!

I recently got nastolgic and decided to dig out my Amigas. I have a A1000 (still with box) and two A2000's. I am focusing on one of the A2000's. Here are the specs:

Rev. 6.2 mobo.
Kickstart 2.04/Workbench 2 Upgraded from 1.2
Microway Flicker Fixer AGA2000
GVP Series II SCSI Controller A2000-HC w/6mb RAM (3.07 ROM)
65 mb hard drive Seagate ST277-N (This thing sounds like a jet engine winding up)
1MB Fat Agnus
Standard Denise
This unit does not have a leaky clock battery (amazing for 15yrs of storage).
Case is very clean and has original mouse and keyboard with no yellowing.

I've started the upgrade process to this machine:
Replace clock battery.
Upgrading to KS 3.1 and WB 3.1


Upgrading SCSI card to 4.15 ROM
  1. What is the maximum usable size for a hard drive? I've read conflicting information of 4.3 and as big as I want.
  2. Can I add and SCSI CD-ROM drive?
Upgrade Denise to Super Denise.

I would like to swap Microway Flicker Fixer for Indivision ECS Flicker Fixer


The Indivision ECS flicker Fixer recommends a Mini Megi/MegAChip upgrade. Those are hard to come by now. Digging around I found a hack called "The Fat A2000". (original article from Amazing Computing - attached) (Expanded text instructions)
  1. Is this mod equivelent to a Mini Megi/MegAChip?
  2. Does the Indivision ECS Flicker Fixer require a clock signal?
At some point I would like to get an accelerator card.
The second A2000 I am going to keep for parts or trade, but here are the specs:
Rev. 6.2 mobo.
Kickstart 1.2/Workbench 1.2
1MB Fat Agnus
Standard Denise
This unit has a leaky battery. Battery has been removed and board cleaned. System still boots.

I will be documenting each step of the process (photos will be included).

Any suggestions are greatly appreciated.

Thanks!

One other thing...I've read that I should replace the capacitors in the power supply because of it's age (can't seem to find the link to that).

True or False?

Thanks!

It certainly won't do any harm in hardware this old, but may not be strictly necessary either. If the capacitors appear bulged or have leaked, then you absolutely must replace them.
