GVP Turbocard 030 Jumper Settings
« on: January 24, 2006, 09:16:36 AM »
Hi,

I own a Turbocard from GVP.
Its Rev 3 RAM8 on this Site:
GVP 68030 RAM 8.
Its in my A2000 Board Rev 4.4 1MB Chip Ram, Kick3.1.

My Problem is, that this Card was only equipped with 4x1MB 30 PIN SIMM Ram's. I found some 1MB Modules an plugged them on the Card. But it does not recognize the new Ram. Workbench still reports ca. 4MB of Memory.

Does anybody know, if there are special Jumpers to set and where they are?

My second Problem is, that on my A2000 the internal Diskdrive is missing. So no internal Diskdrive is attached. But Workbench shows me a Drive Icon "DF0:????". Does anyone know how to fix this? Can i use an A500 internal Diskdrive for my A2000? Or can i disable the internal Floppycontroller?

PS: Sorry for my bad English.

Borgman, don't know about the GVP settings, maybe try BBoAH.  afaik, the A500's floppy should work fine with the A2000, though physically it may not fit quite right and has no face plate.

Maybe you have to insert the SIMMS in pairs, like 4-6 or 8 1MB simms at a time. I don't think there are any jumpers, only on the RAM32 that uses those darn gvp simms.

hope it helps

Is the GVP3001 the only source of RAM?

Also: I do have 2 internal A2000 floppies for sale. Both are mounted on an A200 drive plate, ready to install.

Sorry for the delay in replying - had to dig out my manual.

The picture that you referenced to in your post should have either 4MB (4-1Mx8) or 8MB (8-1Mx8), and NOT the 6MB shown. This is because, according to the GVP manual, that board needs to have four 8-bit SIMMs to get the 32-bit wide data path. This means either 4 or 8 SIMMs. Although, the jumpers shown in the picture are correct for the 4MB RAM-8.

Also, the manual specifies that you use "Nibble-Mode" SIMMs (also called "Nibble Mode Burst", or "NMB"), as regular SIMMs may not work reliably with the board. Check to make sure they're 80nS or faster, too.

Now, if you have 4MB on board, then Jumper J5 is SHORTED. For 8MB, J5 is OPEN. Make sure that you're setting the MEMORY BOARD jumper, and NOT the CPU/Accelerator board jumper. It's recommended that you run the GVP MemTest utility to make sure the RAM is good, and that it supports NMB.

Quick check:
J1 = OPEN
J2 = OPEN
J3 = SHORTED
J4 = SHORTED
J5 > 4MB = SHORTED, 8MB = OPEN
J6 = SHORTED
J7 = OPEN
(You do not need to set jumpers on the CPU/Accelerator board to have it recognize the RAM board.)

HTH,

banzai
