CommodoreDecker Posted February 16, 2021 Share Posted February 16, 2021 (edited) Hi! I bought a Rapidus from an online auction site. The unit looks like the one pictured with the white background ("rapxe"), the top photo. After finding the Rapidus website, their documentation shows two versions of the board - the other includes a secondary board called "Adaptus", which is used on the 800XL. See the bottom photo for this, though its configuration looks nothing like the unit I won. Will the Rapidus (rapxe) require the extra board and ribbon cable? Thanks!

flashjazzcat Posted February 16, 2021 Share Posted February 16, 2021 An 800XL installation will require the Adaptus board. Perhaps Lotharek will sell one separately. 1 Quote Link to comment Share on other sites More sharing options...
CommodoreDecker Posted February 16, 2021 Author Share Posted February 16, 2021 K. I'll check 'em out. Out of curiosity, why is it required? The layout of the 800XL makes direct placement impossible? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted February 16, 2021 Share Posted February 16, 2021 (edited) Correct. The CPU is right at the front of the board and you would have no hope of closing the lid with Rapidus there. The adapter basically relocates the CPU socket to the top right corner. Edited February 16, 2021 by flashjazzcat 1 Quote Link to comment Share on other sites More sharing options...

It's an ingenious design, though I was hoping... the seller clearly got out of an XE model. They're not able to break up kits, which is understandable. Very fast support, which was awesome... I'll be ordering the full kit shortly. Testing with the case open, the Rapidus did boot so that's a big hurdle. Does the Rapidus have an external selector switch? I saw a few connectors, with CON3 looking like a switch could fit in it but am unsure. It's possible the Rapidus is running in "6502C" mode right now and not with the accelerated CPU. Not that I'm itching to test "Rescue on Fractalus" at high speed... even via passthru, if there was a problem, there'd be some anomaly so I'm fairly sure the device works fully but want to double-check as much as possible...

This may depend on what kind of switch do you mean or what would be its purpose. Normally when in 6502 mode the board is idle sitting there and there should be no interferences. You normally control the board using the menu which appears when you press Reset while holding the Inverse key down. If you want to prevent initialization on power-up, just pull the three-wire cable from the connector on the right-bottom corner of the board.
