You can't tell the difference, but text on this screenshot was drawn by bitblt code from 1984 paper smile

Some of the original xerox bitblt code is available in the notetaker firmware btw. The source code is even documented, on http://bitsavers.trailing-edge.com/pdf/xerox/notetaker/memos/19790620_Z-IOP_1.5_ls.pdf

Fixed a few more bugs and IPC feels actually usable now (no obvious video errors etc.). It really needs TMS9914 chip emulated (+ one of supported HP-IB hard disks) to be useful... One day, one day smile

Fixed loading of sector-level disk images from coho.org (the IPC doesn't require magic track 79 after all...), here's a recording of "Point-of-sale demo" from Bundled/IPC_Demos.img

(turns out that raster ops are documented in yet another C include file, scrn/disp.h smile )

(nothing else so far, OS endlessly resets)



So there indeed was a desktop version of IPC, model 9808, without printer: https://groups.io/g/VintHPcom/message/477

Notice at 1:46, the misspelling of "hierachical", should be "hierarchical".
