BASIC 5.1 DIO ROM for 200 and 300 Series computers. This plug-in board significantly increases the performance of 200 Series computers (as well as the 310 and 320) compared to systems with RAM-based operating systems. Documentation for BASIC 5.1 can be found here.
These boards are very rare. Because of the high cost of ROM hardware and the rapidly changing nature of operating systems and software, almost all solutions were RAM-based by the end of the 1980s.Dominique Berget has read the contents of the 12 ROMs on this board and created a replacement for this board, using more modern components. Click More Images to see a photo of the replacement board. In September of 2018, Dominique released an updated version of this board with the following information...
I have just developed the Version # 3 of the dio HPBasic 5.1 + 4Mb Ram Board.
I am very satisfied about this new version. It's now a professionally manufactured printed board. So, the board looks better, and the reliability is equivalent to an original HP Board. This board works perfectly in all the Technical Computers having a dio bus.
I have tested the board with the HP 9826, 9836, 9836C, 9820. This board also works fine in the HP9000-310 and 330, using only the HPBasic 5.1 rom without the ram.
