Does anyone have any documenation on the PC Enterprises mod's? I posted on Vintage COmputer as well, but am looking to recreate the mods (or at least a work around) for things like video and memory. Not sure of the regualr Tandy 1000 mod is the same as the PC Enterprises one and if the memory mod does anything all that special, but am willing to give it a try.

Thanks,

John
