Iâve got a prototype of my hardcopy simulator going. Iâm typing on the keyboard and the âdisplayâ goes to the printer:

The biiiiiiiiiig problem is that the print head and plastic cover make it impossible to see whatâs currently being printed, because this is not a typewriter. This means: In order to see what I just entered, I have to feed the paper back and forth and back and forth ⊠itâs not ideal.
I got that idea of moving back/forth from Drew DeVault, who â as it turned out â did something similar a few years back. (I tried hard to read as little as possible of his blog post, because figuring things out myself is more fun. But that could mean I missed a great idea here or there.)
But hey, at least this is running on my Pentium 133 on SuSE Linux 6.4, printer connected with a parallel cable. đ
(Also, yes, you can see the printouts of earlier tests and, yes, I used ed(1)
wrong at one point. đ€Ș And ls
insisted on using colors âŠ)
