If they are rotting in your stock, you might want to think about rewiring them to XE1541/XM1541/XA1541 adaptors. (Dunno their exact circuitry, this might or might not be possible.) I also have dozens of unsold XEP1541 adaptors - because the XAP1541 is now much more popular - and I've asked Mr. Axel to think of a cheap but (relatively) elegant way to add an XE1541/XM1541 switch to them so that they sell better as switchable XEP1541/XMP1541 adaptors.

I also have dozens of unsold XEP1541 If you look into Michael's shop, you will see that he also offers an XE1541 conversion kit for his adaptors :) I helped him with the instructions for this, and I still use one of these converted adaptors both for tape and disk transfers! In the same way it should be possible to make them work as XM1541 or XA1541 (preferrably with Womo's resistorless design). I also think that in Germany, one problem with decreasing sales of adaptors and cables is the availability of similar items on ebay. Who cares to look for a webshop if he can click "buy it now"?

What? Who? Where? Did I already publish that design somewhere? I believe I did not yet, because there still soo much other things in the "spare time work queue". And still some 'scope measurements for "the other" D-MOS-FET transistors have to be done to get a bigger palette of MOSFET transistors with good measurement results. Currently the BS170 MOSFET (non SMD) is known to work from at least two users. The original discoverer and me. The 2N7002 MOSFET, a SMD type, is known to work from one user, a Finn from a test and debug session of OpenCBM. The 2N7000 MOSFET, again another non-SMD type seems to be untested overall. Maybe many other vertical D-MOS FET transistors may deliver good results, too. And if they are so named "TTL compatible", they really do not need resistors at the base. > I also think that in Germany, one problem with decreasing sales of > adaptors and cables is the availability of similar items on ebay. Who > cares to look for a webshop if he can click "buy it now"? And we know that professional grade Kabelspezialist.de, who started selling XM1541's this year. Womo
