When plugging in the Bigram256+ in my A4000/ROM 3.2/BUSTER 11 or A3000/ROM 3.1/BUSTER 11 the Bigram+ doesn't show up.
I had some difficulties with my A4000 at a certain moment. Yellow screens / sometimes only power led that flashes and nothing else.
I brought my 4000 to a person who looked at it and replaced some sockets. The 4000 was already recapped in 2020. He brought the 4000 (without the Bigram) alive again.
When inserting the Bigram+ .. nothing .. Not showing up in the overview. For and after the socket(rom) replacement the Bigram was not working.
I tried this also in my 3000. Same result. Not showing up.
Other cards that do show up : ZZ9000; Golden gate bridgeboard; TANDEMCD card.
I have also another 256MB (*) module from another shop. But because of being too long i bought one in this shop.
When inserting this (*) module .. it all works and 256MB extra in workbench.
Where to start next ?
Thanks !
