Great !!!
"Hi,
I have posed my Initial Beta of HP85 Disk emulator using an AVR and MicroSD card Schematics included I am spending all my time currently the documentation I will be hosting this on github in the near future What it does: Emulates an AMIGO floppy ( address 700) SS80 disk (address 710) Plotter - captures plot data (720) All three at the same time! While my project can emulate more then one device at once I have yet to add UNIT support - however the code does track the unit assignments I tested this on an a HP85a (with either A or B series ROMs) and an HP54645D scope) I find that using Samsung PRO Micro SD cards avoids a write timeout issue with some SD CARDS (very occasionally a write can take over 100ms - when the device internally updates an entire flash block - typically writes take 2 to 4ms) (It is the small block random IO specs that matter and not the large block write specs most cards advertise) The project was bult on Ubuntu Linux using AVR GCC and avrlibc - it would be very easy to port this to Windows using the Windows ports of the same GCC tools and avrlibc -- Mike Gore magore at sympatico.ca magore at uwaterloo.ca" Systems Analyst 48G+/58C/85B/PC1500A TH-78A/DooGee S9 Focal & All Basic´s |
