that's a very good advice MSX4ever!
OeiOeiVogeltje; Yes, try to flash it on another machine instead of on a Turbo-R
(we didn't try that on the MVM clubday)
Yes we did on a nms 8250 ! And on your own nms8245
But i can flash my sunrise on a turbo-r so why would it be a problem ?
its not on a socket and its small !
i do see something that could be a JIG or something...
So buy a new flashrom and there some people on the MvM club that will want to solder it for you.
But then again you did make a Gr8bit yourself so don't be afraid and just cut if off and solder a new one on there.
Flashrom is the AM29F040B see Farnell
Maybe you can try the idefl128.com for nextor and use the nextor rom... just something else 
on www.konamiman.com
i tried that idefl128.com
but not with the nxtor rom
maybe tomorrow
And ?
Hans Oranje soldered a new flashchip on the PCB and i flashed it and now it works
me happy
and now im searching for a 50 pin SCSI HD to fuss with mt B.e.r.t. Interface
Congrats with the happy return to operation!
I have two Seagate SCSI drives with 50 pin. One in a case with power (the drive of the developer of TED/MEMMAN Ries Vriend ST-138), one without (ST3238 Seagate iirc). Used to work on MSX once, No idea of current condition.
Free for the equivalent of a decent bottle of wine and transport costs.
i also have a lot (almost new) SCSI drives overhere. Without case.
