To all of you 128 users out there I have 2 burning questions: First, is it possible to, on an older 128, upgrade the 16K of video ram to 64K like the 128D. could the 4116 RAM chip used by the 80 col video chip simply be removed and the 4164 RAM chip soldered in it's place? Right now one of my 128's is apart as I've just replaced a couple of bad RAM chips (elswhere in the system) but before I put it back together or try this I was wondering if anyone had similar experience, suggestions, WARNINGS, comments etc. (after all if it 'aint broke don't fix it!) Second: I know of 3 or so CAD programs for the 128 but am looking for recomendations. I don't own any but am considering Homebuilder or Homedesigner or something to that effect. I also believe ABACUS has a 64 AND 128 (128 mode) CAD program and so does another vendor whose name escapes me. what I am interested in is this: - Use of the 80 col chip with graphics(640x200). - Runs in 2MHz FAST mode. - Mouse driven (1351) - Compatible with many printers includeing both 1526 and 801 along with popular non-commodore parallel printers. - Takes advantage of the added 64K of video ram in 128Ds (thats why I'm considering the 64K upgrade above) - Compatible with the 1581 drive. - Supports standard CAD features such as dimension, zoom, layering, etc, that are useful with architectural floorplans, etc mostly 2D but some 3D stuff - Addition niceties though not neccessary: support for plotter and or digitizer? (I'm asking for too much right?) Anyhoooo If anybody can give me any information - much thanks in advance. This may be of enough general interest that I'll post informative answers - Todd
