- These are a few programmes written to help port programmes from the
- Apple ][E to the Microbee :) {Written in 1987 by Luke}
- There is three main parts to this programme set,
- the loader which loads programmes saved on tape from the apple
- (or conversly you could hook the apple directly to the cassette port
- of the microbee) into the microbee's memory.
- and a couple of converter programmes.
- APPLEBAS - converts RAW apple basic into a text format and saves this
- to disk. This can be read in again by typing the following:
- >new
- >open "I",6,"filename"
- >in#6on
- HGRLOAD - This loads apple hires graphics and converts it to a microbee
- standard. The graphics table on the apple has each byte stored
- in reverse to what we would like to display.
- This is handled by the HGRLOAD subroutine.
- Also, the apple has a colour bit attached to the end of every
- byte, which we have to strip off.
- This process is handled by the HGRPIC subroutine.
- HGR pictures take up a lot less disk space than HIRES pictures.
- I know I haven't done it, however, It might be nicer to actually
- save the HGR picture instead of the HIRES picture and call
- the HGRPIC subroutine to display it. HGRPIC is very quick.
- I was amazed at how much quicker you can do things in machine
- code copared to basic. What would've taken 10mins is done in a
- flash!
- SHAPTBL &
- XDRAW Are for converting "shapetables" into PCG graphic characters.
- By this stage I was feeling rather lazy and couldn't be bothered
- writting my own xdraw routine. That would have proved to be a
- lot nicer :)

- It's a pity I've held these programmes for so long, there might've been
- a few more programmes on the microbee if people knew about it!ity I've held these
