I have a problem !

The software nearly works on a 73A jw but will not initalise the LCD properly
on ICEPIC

Problems found so far.
1. RA4 needs a pull up resistor (digital output to LCD RS)
2. Some difficulties with ADCON1 messing up the RA port seem to have fixed
this by turning off the A-D until required.
3. RA4 being assigned to TOC1 Fixed by setting the corect bit in the option
reg
4. I dont think that timing is the problem as the LCD code is ported from
working unit on '84 and OSC is 4.00 on both parts.
What else interfears with RA port (RA5 is LCD EN) and RC0-7 is data has
anybody any ideas sanity is rapidly departing

Thanx in advance Steve....... The man with the sore head........
