At least two different add-on boards were created that gave the H-89 bitmapped graphics capabilities, but I'm pretty sure they both required hardware modifications to tie them in to the terminal board - this was not a simple plug-in expansion card." ...<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> "There's a 3rd party graphics board fitted on top of the CRT (seriously). It links into the PSU/video cableform from the Terminal logic board to the monitor, and also into 8 of the RAM chip sockets on the CPU board. The RAMs you pull to plug in the cables go into the graphics board, which contains another 16K of RAM as a bitmapped display buffer." ...<o:p></o:p> </div> <div>  <o:p></o:p> </div> <div> "OK, the manual says 'Micronex Pixelplotter Graphics on the Z89/RFI computer'. It also says 'Micronex Limited, <st1:Street w:st="on"><st1:address w:st="on">Harford Square</st1:address></st1:Street>, Chew Magna, <st1:place w:st="on"><st1:City w:st="on">Bristol</st1:City>, <st1:country-region w:st="on">England</st1:country-region></st1:place>'. I've got the installation instructions and memory maps. The thing contains 16K of RAM which is bank-switched with 16K of the normal memory. I think my board uses port F2H, bit 3 to select the new 16K, but I'm not absolutely sure." ... ***************************************************************************************************<o:p></o:p> </div> <div> Has any of our SEBHC folks been familiar with any graphics add-on feature for H-89 system?<o:p></o:p> </div> <div> ziloo<o:p></o:p> </div>   <o:p></o:p> <div class=MsoNormal align=center style='text-align:center'> <hr size=1 width="100%" align=center> </div> <a href="http://us.rd.yahoo.com/evt=48250/*http:/searchmarketing.yahoo.com/arp/sponsoredsearch_v9.php?o=US2226&cmp=Yahoo&ctv=AprNI&s=Y&s2=EM&b=50">Pinpoint customers </a>who are looking for what you sell. <o:p></o:p> </div> </body> </html>
