I had Blit serial number 4 here in Sydney. The labs were very generous. It
was great to use until the microvax with 10th edition that the labs sent me
finally gave up.

Do you happen to remember what model keyboard those things shipped with?
I'm also interested in any information about the protocol the depraz
mice spoke -- there appear to have been several models (including a usb
retrofit).

The keyboard was clunky and made from military steel. Don't know the
details.

I know little about the mouse except that it was fantastic!

Bart Locanthi is propably the best one to ask. He is currently working at
Google in Zureich. Also on linkedin.

Tim,

I've already done my own port of the blit emulator to plan9port, but I
didn't publish it anywhere.

Although I see on your GitHub page that you've already solved the
flicker problem, I thought I'd share my own solution as well. The
attached patch was made with plain diff (I didn't put my port under
version control) against 9front prior to changeset 5896 and only
covers blit.c. It also changes the virtual screen drawing algorithm so
it always displays the top left corner, as opposed to centering on the
middle. This is handy on small resolution screens since apparently
rsc's devdraw doesn't allow resizing windows to larger dimensions than
the screen, and not displaying the top of the blit's screen causes the
blit's cursor to be offset from the host system's.

You can also use the added -m flag to supress hiding of the host
cursor to make sure they are aligned.

tkk
