Smokeless Joe Posted June 17, 2016 Share Posted June 17, 2016 Is anyone trying to fit both a VBXE 2.1 and a Rapidus into a 1200XL? I just started to see how they'd fit in the same system and they really don't. Quote Link to comment Share on other sites More sharing options...

Smokeless Joe Posted June 17, 2016 Author Share Posted June 17, 2016 Okay, I see my problem. I ordered the VBXE for XL series when I should have ordered the VBXE for XE/XEGS. Is there any problem with just turning the bottom adapter around? Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 17, 2016 Share Posted June 17, 2016 (edited) The Antic adaptor? I think there should be a direct relationship between the DIP and pin headers on the adaptor board so if you orient the VBXE board the opposite way as well then in theory everything should end up corrected. As for how everything fits - if the mounting point ends up lower down you might run into clearance issues with the keyboard. Of course don't forget, if you do put the adaptor such that it's 180 degrees rotated then the same should also apply to Antic when you replace it in the board.

flashjazzcat Posted June 17, 2016 Share Posted June 17, 2016 (edited) You really need an adapter for the CPU socket. Beetle made a really nice super-low profile adapter from veroboard. The idea is to displace the CPU socket about 5mm back so Rapidus clears the rear of the VBXE (assuming the VBXE is installed with the XE orientation and using an XE Antic adapter). I made a similar CPU adapter but it was a bit taller (I lacked Beetle's patient ability to make adapter legs from cut off resistor legs), but it also throws the socket a bit further back (about three rows, or some 7mm), so everything still fits.

Smokeless Joe Posted June 17, 2016 Author Share Posted June 17, 2016 Yes! The Antic adaptor! That's what it's called. Me use words. I don't think the XL adaptor is gonna do it, even if I desolder it, rotate the board and figure out how to orient the Antic chip. Darn. One of these days I'm going to compile everything I've learned about modding the 1200XL into one document. Maybe it'll help the next poor bastard like me. 3 Quote Link to comment Share on other sites More sharing options...
Xebec Posted November 3, 2016 Share Posted November 3, 2016 Do both the VBXE and Rapidus fit under the keyboard in the 1200XL? Is there any need/benefit for the Ultimate 1MB with these upgrades? (if yes - does that also fit?) Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted November 3, 2016 Share Posted November 3, 2016 Yes, all three can fit if you make a simple CPU adapter to offset the socket about a quarter of an inch backwards and use an XE style VBXE. Without U1MB or some other RAM upgrade (VBXE 320K emulation will do), you'll have no PORTB extended RAM (only 65C816 linear RAM in native mode).
