Device that I select from the speedmaster LV GUI is am27c040(DIP) for eprom and am29F010b(PLCC) for flash.
Well, that's odd, is this one setting which programs both an AM27C040 and an AM29F010B? If so, it appears they are using the same algorithm.
WinLV that i'm using is a older version(1.02), so I cant set anything with it. Maybe if I could increase the delay for the first byte write it could work?
It appears the latest version is WinLV 1.0.0237: EPROM 6.06
AL 6.07:
What version of the algorithms do you have, v6.06? Unfortunately, I am familiar with ICE Technologies, these "pirates" took over or bought Nohau, of which I have three of their ICEs. I basically just boxed them all up and tossed them in storage after dealing with ICE Technologies. Nohau once boasted their software upgrade and maintenance releases would always be free to download, well no more!
By the way, have you ran a blank check on the newly erased EPROM?
LPT1 port is runned in ECP mode.
Is this the recommend LPT port setting in BIOS? I've got both an Advin and a Data I/O 39xx and the Advin started to give me problems programming devices when I upgraded the system hardware and switched to WinXP. I eventually had to install a special LPT driver to overcome the problem. It appears to be transparent to all applications and doesn't interfere with normal operation. I've attached the install if you want to give it a shot, it is specifically for WIN XP/NT.
It maybe time to consider picking up another programmer, if you can find a used Advin, I wouldn't hesitate. They got great customer support and free software upgrades, which seems to be rare these days. Also they provide legacy software for the older programmer models still out there, another rarity.
Hope the info helps in your endeavors.
