Sorry to take this off topic still further.

Please excuse me being nosey, but is it a matter of speed , features,  
user interface, opening ClarisDraw files, price or what? My company  
took over 'MacDraft' from IDD many years ago and still supply both  
MacDraft and the cheaper version MacDraft PE (personal edition) which  
are both universal binaries on OS-X. We get some people complaining  
that the UI is not modern enough and others that its too modern. We  
do not currently have any sort of gradient fills, maybe that's what  
is missing. We are currently working on version 6.0 so would be  
interested if you or any others on this list would like to tell me  
what we need to do to meet your needs, though of course we don't make  
programs for one users needs alone.

To bring back on topic, last month we got the core memory of my  
ICT1301 back to 100% functionality, all 2000 words of 48 bits  
(1200lbs weight). We're now working on an interface to write data to  
a parallel port so we can catch it with a modern machine. We're using  
TTL working from a -5v supply as Vss and ground as Vcc to match up  
with the -6.3 volt logic levels (with an implicit inversion). We're  
also using an IDT 7201 FIFO to buffer the rapid supply of 48 bits  
from a word against the 8 bit at a time parallel port, and it may  
also absorbs some of the difference between rapid data transfer of  
each mag tape block and no data during the inter-block gap with the  
constant data rate of the parallel port.
