Amiga 4000 Desktop Computer With 68040 25MHz CPU - Complete
Item History & Price
This A4000D has had:the motherboard recappedbattery replaced and clock fixedthe Buster chip upgraded to Version 11a CD-R/W addedan uncommon "short" second Amiga FDD addedand has been tested to work with the Mediator, CyberStorm MK II & PPC and OS4.1the key fits, works and is connected; in the locked position, the CIA chips will seem defective as the mouse and keyboard are locked out.It comes with a set of 3.1 ROMs, face plates for the FDD and 5.25 drive bay, original manuals and WB... 3.0 disks, a new set of WB disks, and the OS3.2 CD Package. Although not shown, the main computer is shipped in its original & intact styrofoam protection. This 4000D was used as a backup computer and was removed from its box with all else left unused. It has an HD Floppy drive, WB 3.2, and non-proprietary software added from the Aminet Website to make life easier. There are some no longer proprietary software packages from the Internet Archive site, TOSEC. As this computer is 29 years old, and its maintenance has cost hundreds of dollars, thus, it is sold as is, and is sold for parts or repair as it will need ongoing work/repair to keep it working and useful to the owner for another 29 years.
From the web (modified):CommodoreAmiga A4000/040In 1992 September, Commodore released the successor of the A3000 based aroundthe AGA chip set. The first models were equipped with 040 processors only, later - to fill the gap between the A1200 and the A4000/040 - with 030processors too. Apart from the used processor cards, the two models areidentical.Processor68040 @ 25-40 MHz
This A4000 has been tested with 68060 @ 60 MHz & PowerPC 604e @ 233 MHz andcan run OS4.1. An A3630 has been shown to work as well.Memory2 MB Chip RAM
16 MB Fast RAM on motherboard
(up to 128 MB Fast RAM on processor cards)
(up to 1 GB Fast RAM on Zorro III expansion cards)This A4000 has five 72 pin SIMM sockets on their motherboard- one for Chip RAM, the other four for Fast RAM. The sockets accept industrystandard 32- or 36-bit page mode SIMMs. The four parity bits of the 36-bitmodules are ignored, and they function as simple 32-bit ones. The Chip RAMsocket has to be filled with either a 1 or 2 MB SIMM. The four Fast RAM socketsaccept 1, 4 or 8 MB modules up to a total of 16 MB Fast RAM. The SIMMscannot be mixed and the 8 MB ones have to be placed in every second socket.
Late models have the four Fast RAM sockets only. The fifth socket is missing, it is replaced by 2 MB 70 ns Chip RAM soldered to the motherboard.
The access speed of the Fast RAM on the motherboard can be controlled bysoftware, either 80 or 60 ns.Custom chipsAlice - AGA display controller

Theaccess speed of the ROM is selectable by a jumper, either 160 or 200 ns.This one has KS 3.2 ROMs & WorkBench. This A4000s was upgraded from a Super Buster revision 9 chip to a version 11. Dueto having problems with Zorro III cards using DMA. Expansion slots1× processor card slot
4× Zorro III slots
1× extended video slot
3× inactive ISA slotsThe Zorro, ISA and video slots are all placed on a daughter board which is mounted vertically on the motherboard. All the ISA andvideo slots are in line with a Zorro III slot.
The video slot is extended with 18 pins not found in previous Amiga models inorder to support the AGA chip set's 24-bit color palette.
The three ISA slots have their power and ground pins activated only. In orderto access the slots by the A4000, a BridgeBoard has to be installed. With aninstalled BridgeBoard two ISA AT compatible cards can be used in the remainingslots. Inactive slots can be used for non-intelligent cards like TBCs or fancards.
The processor card slot is physically the same 200 pin one which can be foundin the A3000(T). However, the processor cards designed especially for the A3000do not fit into the A4000 because of their size - the A4000's daughter board stands in their way.The A4000 has a vast array of upgrade options, including processor cards, SCSI controllers, retargetable graphics cards, video digitizers, Ethernet cards and many other types of expansion. Some of which will be available for purchase by the new owner after sale, on such sites as Amibay, etc. On Jul-31-21 at 09:07:12 PDT, seller added the following information:The photo of the ROMs shows OS 3.1.4 labels placed on 3.2 ROMs burned from the OS3.2 CD to prevent erasure. The original power cord is included.
