Assembling AA3000+ boards for matt3k
01.01.2020 - 02.01.2020
I've begun assembling the AA3000+ board set for matt3k a couple of days ago. After two long days of soldering all the passive components etc. (resistors, capacitors [except polymers], ferrite beads, transistors, diodes, ...) and over half of the glue logic chips are in place. Next to solder the small pitched SSOP glue logic chips.

18.01.2020 - 19.01.2020
All custom chips, CPU and FPU sockets and processors, SCSI and Kickstart sockets and chips, DSP processor, polymer capacitors, most of the connectors and other miscellaneous parts soldered. A few connectors left to install. After that the boards are ready for testing.

The boards have been fully assembled and passed the tests. The supplied Ramsey-07 was bad and gave all sorts of stability issues with A3640. After swapping the Ramsey-07 with another one, the board ran stable with the on-board 68030 and also with the A3640. The SuperDMAC-04 and Ramsey-07 got socketed in the process.
