 The ECB KISS-68030 prototype board schematics are contained in this folder. This board should be considered EXPERIMENTAL at the present stage, prototype 1.0-005. The CPU board represents a direct upgrade from the Mini-M68000 board in the N8VEM ECB 100mm x 160mm format.
+[update: 1.0-005 updated with 1 wire to 1.1 is the operational final board. See the update page to download the update PDF and Schematic update on p.4.]
 CPU: Motorola MC68030RC-16, with provision for -20 and -25 Mhz chips. [board is stable at 25Mhz; reports received from several users that 32Mhz is operational.]

+==== A note on U403 ====
+Will Sowerbutts (2023-03-19): I've now seen two KISS-68030 boards that fail the memory tests repeatedly. One failed at 5.0V power supply but passed at 5.2V. Both boards were fixed by changing U403 to a Philips 74F195AN, both boards became stable at power supply voltages all the way down to 4.0V with this part fitted. Philips 74F195AN seems to be the magic part. A National Semiconductor 74F195AN did not work at 5.0V; it seems the Philips part is better in some way.
