This cpc,always has strange problems when returned from technical service.
For example.When I load a game that load a second fichier after call llamade,Sometimes He not load the new block.Because He found the name it search! XD(and ignore the block).
Hi,
A 200 ns RAM is absolutely ok for the CPC.
But the error you describe seems to be a tape-error. I can't see the connection to RAM.
