..what would you suggest as a place to look for those? I am in 
a somwhat similar situation as djordj - I have got a MX51, model 
MX51-A-19, serial number 647 but I am in need for the software 
(any platform would be OK) and the DIL40 adapter cable since I 
want to work on a 8751 based design...

I am monitoring eBay for 6 months now, but no success especially on 
the DIL40 cable...

    Thanks and best regards,

       Erik.

Thanks for the advices.
I'll try to find them.

For many 51's you use a hooks part so there is no difference.

Depends on your problems :

I'd much rather emulate with the same silicon as I ship :)
- as an example, the last two 'Emulation Needed issues' we tracked
down, related to Silicon peripheral issues.
(and subtle variations from the datasheets)

If the emulator uses bondout, or different silicon, you have a blind
spot.

Either of those are a LOT better than a JTAG.

Saw this thread a bit late.

If the OP is in Australia, still around and interested I *do* have a 
Nohau EMUL51 emulator board set though I doubt anyone has the 2 x ISA 
slots anymore that these require...

Alternatively I also have a Philips PDS51 (made in NZ) and if anyone is 
still reading ;-) a CIEBO 750 kit (Philips 87X750,1 & 2 micros).

Chris.

You must work for Silabs!  There is a world of difference between  a
JTAG and an Emulator.

Also the OP has stated that it is an 8051 on a PC that does not have a
JTAG or ISP. SO your solution is a non starter anyway.

I stand by my suggestion of looking for a second hand Hitex or Nohau
ICE.

After using various ICE's over a period of 20 years. The best one thus
far is a debugging tool I=92ve build from a silabs F020 and using the
Keil uVision 2 debugger through a silab jtag interface. All the
relevant pins for a 40-pin =9251 was brought out on my design and with
careful manipulation of the clock (the f020 runs 12 times faster at
the same clock) ive got a tool the gives me more value than any of
those expensive emulators.

This looks great for teaching the basic 8051 but I don't think it is
suitable as an emulator replacement.

I would suggest a replacement for a Brendes Biceps-V would be one of the
old Hitex or Nohau ICE.  There must be a lot of those going spare.

There is the Keil simulator (as shown on the Brendes web site)  as this
has support for many of the 8051 variants. The free one has a 4K limit.
