Lo de la ROM que se queda "pegada" parece que es comun.
Esto es lo que me escribio Ben en su momento.
There could be several reasons for the problems; I’ve made a standard email with info and how to solve this:
In some situations in the past one of the GAL chips on the DivIDE went corrupt, after sending.
Of course I test all DivIDE interfaces before sending.
If this is the case, it is easy to solve: I can send a replacement GAL chip set.
But it doesn’t have to be the DivIDE which causes the problem.
I have had dozens of ZX Spectrums myself with a problem which caused the DivIDE to malfunction.
Possible problems for this are the Z80-signal strength (‘fanout’), Z80’s with a defective M1 line, ROM’s which keep paged in allthough they shouldn’t, aging causing bad soldering contacts, and more reasons.

Or try testing interfaces like Interface 1, PlusD, Disciple, Multiface; if these fail, it’s the ZX Spectrum.
If it’s not possible to do these tests, I can of course send the chips, but that will not make sure the problem dissapears. Please let me know what you want.
