Can I change or edit RomEm contents while it is connected to my
A: Yes, but doing to will disrupt its operation in your target
system. Generally, a reset is necessary after displaying, modifying,
or downloading new data to RomEm.
Q: Can I emulate Flash memory?
A: Yes. Many people use RomEm to emulate flash. But you cannot
write to RomEm from your target system, so it will be read only
from that side. Most flash parts have the same JEDEC standard
pinout as EPROMS, but if yours has any differences, slight modifications
might have to be made. The RomEm manual has complete pinouts of
all supported EPROM types.
Q: If I buy a smaller size RomEm, can I upgrade it later?
A: Yes. We charge only the difference in price between the two
units. We do ask that you return it to us for the upgrade so that
we can fully test it to insure quality.
Q: Can I load RomEm with one type of file, like an Intel hex,
and write it out to another, like Motorola S or binary?
A: Yes. In fact, you could use the RomEm control software to make
file conversions of this type without even having a RomEm unit
attached! You can do so by using your PC's memory to store the
data instead of RomEm. _______________________________________________________________
Q: Can RomEm be used to emulate a 16 bit EPROM?
A: Yes. It requires two RomEm units, and a custom adapter to convert
the two 32 pin DIP headers to one header which matches your EPROM
Q: Can RomEm be used to emulate two 8 bit EPROMS
in a 16 bit system, or four 8 bit EPROMS in a 32 bit system?
A: Yes. You need one RomEm for each 8 bit EPROM. Up to 4 USB RomEms
can be connected to one computer using separate USB cables. A
USB hub can be used to facilitate multiple connections. _______________________________________________________________
Q: RomEm comes with a 32 pin DIP cable, but I only need to
emulate smaller parts which have 28 pins. What do I do?
A: You can request a 28 pin cable from us instead of the 32 pin
cable. Or you can use the standard 32 pin cable, and "bottom
justify" it in your target socket. That is, leave pins 1,2,
31 and 32 unconnected.
