Hi, all ULAs are working :)

2 boards (issue 3b) has been repaired:

- board 1, changed Z80 and a 4116 DRAM. Total time: about 20 minutes.

- board 2, original parts missing: power connector, modulator, ZTX650, broken 14MHz crystal; after fitting missing parts, changed a 4116 DRAM and sorting 4532 DRAM because they was mixed (NL3 and NL4) with jumper set to NL4 type. Total time: about 1 hour.


Next board to fix is one of three issue 6a ;)

Cheers
