|  Re: Layout of userport cartridge
MIK,
.....There are a couple of open carts on the Hardware page if that's of any help?....
Unfortunately, the pictures don't help me very much - they only keep me jealous when looking at the nice & neat positioning of the hardware items on each of those boards....
What I'm looking for is a real "blueprint" of such a board, enabling me to copy the layout and to build such a board on my own.
In the old days, I someday took the 3+1 stuff out of their internal sockets and replaced them with the Script+ eproms (I even had an eprom burning device by that time). The external board carried Calc+ which was on lo & hi eproms as well.
Oh man, its such a long time ago... To remember every move I did 25 years ago is a real challenge...I'm not getting younger....
But I'm working on it. ---- Today, after a long waiting time, an Ebay-bought Plus/4 + 1551 + 1531 were delivered by an exhausted TNT guy. In WORKING condition (not the TNT driver who was exhausted -Saturday eve!-, but the Plus/4 keys are O.K., and everything RUNS!!!!)
The good times are going on to roll again!
Regards,
Hans.
