To restore, filename in Alpha, 800 in X, XEQ RDROM16.

Those RDROM16 and WRROM16 routines are fairly easy to use. The issue is to connect the HP-IL module without getting bus conflicts and to get the CLILUP module into the memory map. Well, it is always good with alternatives...

There is a manual - you just provided it! Thank you. Indeed, its always good to have options.

After having a look at it, it seems the instruction above will not work. The reason is that RDROM16 prevents you from loading to page 800 as it is deemed dangerous. Instead you need to load it to another RAM page (807 or above), then move it into 800.
