Amiga 2000 Restoration – Part 2

Power up test with the Kickstart 3.1 ROM installed.

Whats the difference between a Cloanto and a Hyperion 3.1 ROM? See below:

exec.library 40.12

  • Updated copyright information text
  • Fixed a small bug in the memory pools code which mirrors the same bug fix in the same code that was used in amiga.lib.

strap 40.3

  • Added the Boingball logo which replaces the rainbow-coloured checkmark logo. Slightly brighter background colour.

workbench.library 40.6

  • Rebuilt with SAS/C 6.59 to free up more ROM space because the copyright text in the updated exec.library. No other functional changes.

scsi.device 40.21 for A600

  • Small bug fix to the IDE task initialization making is compatible with the A600. (Note: older Kickstart ROMs used scsi.device version 39, because unlike version 40, it did not crash on the A600)

scsi.device 40.21 for A1200

  • Same binary as used for the A600

SCSI Hard Disk Controller

I purchased a GVP HC+8 SCSI hard disk controller with 4GB hard disk and CD-ROM with 8 megabytes of RAM installed.

GVP HC_8

Microway AGA-2000 Flicker Fixer

Flicker Fixer which allows the addition of a VGA type monitor to display the Amiga’s native video. As the name might suggest “AGA” this card is not designed for use in AGA systems such as the A4000. The term AGA for the card was obviously coined before the AGA chipset came into existence.

The card actually has an EGA style DB9 connector for use with older monitors, so to connect a standard VGA/SVGA monitor to it you’ll require an adapter.

This card was essential as I don’t have a compatible analog RGB monitor (1084D or 1084S). All flicker fixers work great with CRT monitors. LCD monitors are a different story as they show what is called “banding”. Banding is vertical lines on the LCD monitor. It can be sort of adjusted out, but the banding is still visible. The only solution to this problem is either finding a CRT type Super VGA monitor or find a ReTargetable Graphics (RTG) card. Vintage RTG cards are becoming expensive these days. There are other options, such as the VMT2000 graphics card. The VMT is an open source RTG card.

GVP Impact 030 Combo Accelerator

The GVP Impact 030 Combo accelerator is designed to plug into the CPU Fast slot of the A2000. The card takes GVP 64pin SIMMs which are not necessarily compatible with the various other 64pin SIMM formats that exist. The card also contains a SCSI-II controller providing both an internal 50pin SCSI connector, and an external DB25 connector.

This card has 1 megabyte of RAM soldered on the board with three SIMM slots. It can accept a total of 12 megabytes of RAM for a total 13 megabytes of RAM.

GOTEK Installation

My Gotek wasn’t flashed with the right software when I purchased it. After watching this YouTube videos, I was off to my local Fry’s to get a header and an FTDI.

I found an OSEPP FTDI, so I picked it up. I soldered the header to the Gotek and set out to reflash with the right software.FTDI

I noticed that no one was using the FTDI that I had, but I was determined to make it work. After I downloaded the software from the OSEPP website, my PC found the FTDI connected via usb. To program the Gotek, out is important to set the VCC to 3.3v.

Connect the Receive and Transmit to the Gotek and the ground to the ground and the VCC to the 5v line on the Gotek.

Install the Flash Floppy hex software using the ST software package.

A2K_2018

Here is the completed restoration of the A2000. Eventually, there will be another A-Max II+ card in this system. It’s just a matter of finding one. They seem to be hard to find these days, but I will prevail. I’m certain of it. Someone out there must have one just laying around.

Shortly after the above picture was taken, I started having hard crashes with the system. After some research, I came to the conclusion that the power supply was going bad. I found another power supply from a very reputable source on eBay and purchased it. I removed the faulty power supply and installed the other. Since then, I haven’t experienced any issues with this computer. (Knock on wood)

Here it is with the new power supply installed prior to reassembly. I’ve always liked that Deluxe Paint King Tut graphic.
