Paul,

I can't say whether this meets the N8VEM project goals, or not, but that is a heck of a cool project! I'm a 68k-series fan, myself, and I'd love to build and test a board, like this.

I'll be very curious to hear where you go, with this project.

Thanks!

- Alex

Hi Guys!

Been a lurker on the group for some time now, this is my first post.

Anyway, I've been wanting to do a 68030 system for many years and went through several false starts. Finally I found enough time end energy to pull something together.

I suppose it doesn't meet the N8VEM design status quo of using free software (been a Proteus user for years), has programmable logic (16V8 GALS), and uses SMD for video and ethernet.

Attached is my design of the "Gryphon Oh-thirty" single board computer. This is not yet built, I've just sent out for a run of 5 boards.

Specs are

MC68030 @ 25MHz
MC68882 @ 25MHz
32M DRAM via 8422V Controller
512K SRAM (to help get it initially running)
512K FLASH
Parallel Port
2 Serial Ports
8x42 Keyboard/Mouse Controller
AY-3-8910 Sound
37C65 FDC
IDE interface
RTC 72421 Clock
RTL8019AS Ethernet
S1D13505 Video (800x600) - (In a TQFP-128 to PGA-128 SMT Adapter)

Gerber files were rendered with http://www.zofzpcb.com/ for the image

I'm a hobbyist, not an engineer so I expect there are some problems lurking...

Paul

PS

Hi Andrew. Not sure if you remember me, but I picked up the ebay terminal from you in Dayton last year. We had a nice discussion about the N8VEM project and I bought some boards (Still unpopulated and on my to-do list)
