One of my favorite old computers to tinker with is a

recently moved it out into my living room to hopefully inspire me to
mess with it more, but I still didn?t want to mess with having to put
everything on 360k floppies. With all the slots occupied I had to find
another solution for mass storage. Raspberry Pi to the rescue! I was
able to use XTIDE and a Pi to emulate a hard drive over the RS232 port.
All the details are here on my blog post:

Nice job.
But, why give up an entire ISA slot just to hold a DB25 and a DA15
connector? You coulda made up a Compact Flash or SD card pseudo
hard-drive that ALSO has a DE9 and DA15 connector on its bracket.
BTW, the original 5150 also had an empty ROM socket.
