View Full Version : A new 68030 S100 Bus CPU Board

October 2nd, 2017, 09:48 AM
I am delighted to report that our new 68030 master/Slave S100 bus CPU board is now ready for bare board orders. The board is described in detail here:-

Relative to a number of our other S100Computers boards I think you will find this one somewhat easy to build. If you take care and burn the CPLD, GALs and ROM it should come up the first time if you have the jumpers correct. For debugging however I have added a number of very short test routines of increasing complexity to burn into the onboard ROM. The board can address all the S100 bus RAM (16MB) and up to (in theory) 4GB of RAM if the OTT RAM bus is used. It's rock solid with a 10MHz bus Phi clock (40MHz Oscillator). No wait states are required with our 32 bit 32MB OTT RAM board (or on the S100 bus) – in my system.

If you would like one or more of these boards please reply here. They will cost $18 + shipping, payable with PayPal when you receive the board. “Regular” S100Computers users, I have your shipping address. Any new users, I will contact you directly. Do NOT send me regular e-mails requesting the board. Only “orders” listed here will be filled. I will publish a shipping order list later here:-

It will only be updated every few days. The boards will be done by PCBCart (China) and will take 3-4 weeks to arrive.
