Note: Unfortunately, no schematics are available for any of these accelerator boards, which can make them difficult (if not impossible) to repair.

T-Rex G-Force 040-40

The A4000 G-Force 040 40 User's Guide is now available! Its addendum, the A4000 G-Force 040 User's Guide Addendum, is also available. Note that the key parts of the Addendum from pages 3 and 4 have been merged into the User's Guide.

My sincere thanks to eBay seller vannysue_6 who provided me with the photos (Page 1 | Page 2 | Page 3 | Page 4) of this hard-to-find Addendum on April 30, 2021. If you have any other original A4000 G-Force 040 / T-Rex documentation not yet available here, please e-mail me.

How to overclock your G-Force 040 40: Overclocking the GVP 4040 TREX-1. Thanks to Robert Miranda for sending this info. He adds some additional notes:

T-Rex II A4060DT

Robert Miranda notes:

"The GVP-M website mentions the A4060 T-Rex II disk is for the A4000 Desktop — this later card won't work in the Amiga 3000s because of the (known) missing INT2 line on the CPU slot. The ReAmiga 3000 has the line, and accelerator cards which have SCSI I/O interfaces work as a result."

Apart from jumper information and on-disk "ReadMe" notes, there is apparently no known official manual for the T-Rex II card. However, if you have any other original T-Rex II 4060DT documentation not seen here, please e-mail me.

Many thanks to eBay seller vannysue_6 for sending me photos (Page 1 | Page 2 | Page 3 | Page 4 | Silkscreen/Jumpers Closeup) of the following hard-to-find documentation, including a closeup of the silkscreen with the jumpers layout (posted April 30, 2021).

Note that JR4 on page 3 appears to have a typo; the title says "Burst Write Enabled", but it apparently should read "Burst Read Enabled" to match the setting text below it. This has been corrected in the PDF version.
