Editing UCSD Pascal (section)

===Version IV===
Commercial version, developed and sold by SofTech. Based on Version II; did not include changes from Version III. Did not sell well due to combination of their pricing structure, performance problems due to p-code interpreter, and competition with native operating systems (on top of which it often ran). After SofTech dropped the product, it was picked up by Pecan Systems, a relatively small company formed of p-System users and fans. Sales revived somewhat, due mostly to Pecan's reasonable pricing structure, but the p-System and UCSD Pascal gradually lost the market to native operating systems and compilers. Available for the [[TI-99/4A]] equipped with p-code card, [[Commodore PET|Commodore CBM 8096]], Sage IV, [[HP_9000#Series_200|HP 9000]], and [[BBC Micro]] with 6502 second processor.<ref name="beebug198501_pascal">{{ cite magazine | url=https://archive.org/details/beebugv0308/page/7/mode/1up | title=Acornsoft's UCSD Pascal System | magazine=Beebug | last1=Maher | first1=John | date=January 1985 | access-date=2 July 2024 | pages=7–10 }}</ref>
