Is there enough interest out there for a production run of the PCJr Sprint Board.
I have and older unit, an original from D.Severson, and would be willing to layout a new PCB and build some up if there are enough folks that would like to have this...

I'm definitely interested in one or two.

Any chance you could address viewtopic.php?f=1&t=735&hilit=sprint&start=10#p5484 before starting your run? I'm very curious to see what the actual speed increase is. There are scores in that database for 9.54 MHz 8086s and 8088s, but not a 9.54 MHz NEC V20.

Yes I just downloaded your TOPBENCH and ran it last night on my system at home..
it was ( 6 ) with the V-20 chip but did not have the PCSPRINT in that system

I am finishing up the COLOR system and will run it next week..

Q: does TOPBENCH update the database file ?
how do I get you the results.....

When you have an NEC V20 + Sprint, that number should be 10 or more. Just add it to the database from inside the program (Database->Add), then exit the program gracefully back to DOS and then email me the database.ini file and I'll add it to the distro. My email should be at the top of the DATABASE.INI file.

Yes, I definitely think there would be a demand for a PCB that users could print out from OSH Park or PCB Way.
