Could another solution be the emulator EightyOne? Is it possible to transfer programs from EightyOne to the Lambda, from PC soundcard into the Lambda EAR input? It is certainly possible with some emulators to output “loading sounds” to the “retro” computer. But I don’t know if EightyOne can do this...

One way is TZXduino, but apparently no PCB is produced anymore? A quick search on eBay lists 12 replies for TZXduino. https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1313&_nkw=tzxduino&_sacat=0 There are both cheap assembled devices and raw PCBs. Martin Thanks - Ordered an assemble...

Hi all I purchased a shoebox tape cassette recorder, and made several attempts to SAVE/LOAD from/to the Lambda - absolutely no luck at all! As Martin wrote earlier in this thread: "I have not succeeded to save programs, as the voltage is much lower, and the TZXduino does not support save." So, for n...

Hi The dictaphone (Olympus LS-3) is actually capable recording the relative weak signal, but with a little background noise. It sounds as i remember a valid data sound. (Very objective....i know) After several tests with different recording/replay settings, into the EAR plug - with the Lambda 8300 i...

Hi Mark

Yes, i remember the ractangular casette recorders we used to save/load the Marathon 32K with.
I think you are right, about the signal levels.
I found an 10 years old dictaphone with MIC in, and EAR out - i will give it a shot tomorrow.
In case of no success - i will find me a “shoebox”.

Hi again Partly success: Now "datasound" is comming into laptop this way: Lambda 8300-MIC-jack plug mono -> jack plug stereo - laptop soundcard MIC input - PC Software "WawePad". The level recorded is relatively low, nevertheless input amplifier is tuned to max. No success with LOAD"" via EAR, yet -...

Hi XavSnap

I am using mono jack plugs into the Lambda 8300, and stereo jack into PC soundcard.

Hi All

Disregard this question/issue.
The computer sockets are NOT Phono, but JACK SOCKETS!
I am on the right track again and will return when further testing is done.

Hi all "The 2 attached pictures shows, that no metal is covering the circular plastic outside of the phono socket in the Your Computer. Thats why my "missing GND" question." Disregard this question/issue. The computer sockets are NOT Phono, but JACK SOCKETS! I am on the right track again and will re...
