Hey, that would be great if you could do, and I may learn a lot!

>I didn't mean to interrupt and monopolize your thread. No problem, really! (I have put this thread anyway in the wrong area of the forum. ) To see the pictures of your machine is a big pleasure, I think not only for me.

Re: Lambda 8300/Power 3000 Mutlirom

Hello,


here now the final version. I will order two protoype PCBs this week. To keep prices low it will be delivered within 3 weeks, so before the ZX TEAM meeting in Germany I could perhaps finish one and test.

Re: Lambda 8300/Power 3000 Mutlirom

Sorry I forgot to mention. When I tried to use a 16k memory expansion from ZX81 with the Lambda, it got defect. Maybe it was a case of random, maybe it was one of the very first 16k packs from sinclair, which was critical to some signals .... I dunno. Maybe some other persons here or in the german f...

Re: Lambda 8300/Power 3000 Mutlirom

Hello TMAOne, for me it is difficult to give you an advice if you should by the same. 30$ is in my opinion OK, if the machine is in a good condition and maybe equiped with a 16K Ram expansion. Here in Europe I bought the same for 20€, but with some scratches and holes on the case. The Lambda will ne...
