Hi!
My idea is long time in my head 'cause I have not easy access to devices connected to Expansion Port.
Is possible to create cable with edge connectors Male and Female to connect to expansion port outside connector?
I know that timing and similar problems can happen...
Always when I asked anybody, answer was same: No, impossible.
So, why I'm asking again?
First attempt was to put Nexys4DDR FPGA into 1541 case and connect cable enlargement to microSD slot for easy SD card exchange - I'm running not only Mega 65 of FPGA.
I bought 30 cm cable, failed, my hopes were lost.
I shared it with Paul Stephen-Gardner and he said that maybe smaller cable can work.
I bought 10 cm cable and success - now I have Nexys4DDR in 1541 case and I can exchange SD card everytime I want.
But it was not enough to write this thread.
I bought new MB and CPU etc. for my new PC and there was only one PCI slot.
I bought Riser (look at photos below).
Problem of riser is orientation of slots, so it was impossible to use... but for compare Commodore "Riser" can be named X-Pander-3 or pass-thru port or so...
So, I found PCI cable enlargement which allows me to connect PCI devices like I want.
And this is reason for this thread...
When can PCI enlargement work, why cannot Expansion Port work similar?
Clocking and other problems I accept, but when is compared data and state flow - PC has many time higher than Commodore 128...
We, Commodore 128 users, have riser - X-Pander-3
Can we have enlargement cable? Like this:
Enlargement cable
PCI riser
What do you mean?
I mean everybody want have peripherals easy to use...
Of course, I understand that SuperCPU can have problem, but it has pass-thru port, CP/M cartridge maybe, but is it only dream?
