Dear EUG,
Over the last couple of years countless people have mentioned to
me that they are always short of Master 128 ROM cartridges.After much
research I have found a company that does good double sided plated through
hole PCBs and am now able to offer these to EUG members.See the seperate
article elsewhere on this issue.
I built computer controlled TV over Easter,as I intend to use two of
these to pick up Nicam sound and colour vision in a tiny box,without the
need to cart round two 14" picture tubes too! The TV card itself was
simply an off the shelf project from Maplin which the originally designed
to pick up Teletext on a PC.But the 45 card that slotted into the back of
a PC was too much to pay,so I decided it would be easier to design my own
for a fiver.All that was needed to control the selection of the station is
a voltage from 0 to 12v.The digital to analogue converter I used is
included on this issue as part of my 'Buildit' series.
While working on my OS_Prettyprint ROM image (users of Risc OS machines
will be familiar with this - it's a compressed text printer) I had the
need for a wordwrapper.Since this is also of use in other areas (eg.a word
processor) I decided to submit this as a stand alone machine code program.
While I'm getting my wordsworth (pun definately intended) I've also
sent a simple word counter that I use to estimate how close I am to the
2000 word limit on my reports that I have to do for university.Hope it is
of use...
