So, I am in the lucky situation that i have just revived an old IBM machine. However, the problem with the machine is, that it has only IBM MCA card expansions, the harddrive is ESDI and the only communication options it has, is a DB25 parallelport and a DB25 Serial port. And also a PS/2 port (of which its famous). My disk-drive on it, is broken..
So, I have DOS 5.2, QBasic - and a lot of potential time.
My thoughts were to make a serial or parallel-port transferring programming, in Basic, both on the P70 and on the sending machine - my 200mhz DOS-gaming machine. That way I could probably send over some smarter programs, than the one I plan to build.
So, one of the things I thought of building, and im not sure if this is possible, is a small EPROM-adapter. And arduino holds address-pin on an EEPROM, the data pins are wired to the parallelport D0-7. The arduino listens on one of the parallel pins, lets say Linefeed, when this is changes to high, the arduino increments the address lines by +1. This changes the eprom output - which can be read by the PC and saved. This will probably work, but I feel its a dumb solution.
Another way would simply be to use my 200mhz DOS gaming machine, to make a sending-program, however Im not really all that well traversed in "real parallel talk" - and especially not in qbasic.
Can anyone help?Statistics: Posted by chucker — Thu Aug 02, 2018 7:24 am
