Well this is embarrassing. I should have just looked at Wikipedia first.
According to the Pede, they liquidated July, 1995, and a company GVP-M took over the assets. Alas, the site shows a number of products, but reports as last being updated in 2003, and Buy Online links redirect to some Japanese sites.
There is a pretty cool Amiga Hardware Database, that has a list and images of GVP Products.
The specific product I remember so fondly is the GVP G-Force 040 for the Amiga 2000.
4 DIMM slots, had 16 MB. (Considering the 1MB my A2000 had previously, this was world changing).
SCSI port, so hard drives became an option.
Motorola 68040 at 25 Mhz (vs the 68000 at 8 Mhz).
Configured this way it was a multitasking beast. I sold it, alas, I wish I could power it up now, and see how it 'feels' compared to my work laptop, a 4 core Intel i7 at 2.4Ghz, and 16GB of RAM with an SSD drive.
- 1024 times the RAM
- 96 times the CPU (But X3 for the three extra cores, ignoring execution units, and ops per cycle)
- Disk speed I cannot compare. 3600 rpm SCSI-1 vs SATA-II SSD.
