In the late 1970'ties, I had a AIM65 system, and sold some 35-40 pcs. of this fine system to HAM-radioamateurs. It was quite advanced at the time, with RM65 Piggyback, CRT-controller, Floppy-Controller for 2 x dobbeltsidet, dobbelt densiti disksystem,in all, 36 K byte RAM so it worked great with 2 PASS Assembler, PL1, Forth, Pascal, 12 K disk-oriented Basic (a copy af Commodore64 Basic), and it gave me a lot of fun
.
In 1985 I changed my work, to operator on large Gunverment Computersystem, and I had to put my vintage system out in the garage, and 10 years after it went to the dump.
Few weeks ago, I had a talk with another HAM-fellow, and he had a AIM65 system he would give to me, as he heard my vintage story, so now... I am in a nostalgic periode of my 75 years old life.
The last 15 years I have my pension, worked my HAM-radio, and had a look at ARDUINO for different projects.
It had a lot of fun making a homemade 3D-printer, and measuring instrument for the HAM's, and other HAM-related projects, and now I have the AIM65 up and running, after i found a box, diip back in my garage with some ROM's EPROMS and other AIM65 related stuff.
Some HAM-friends have donated a tape-station, and now it is running fine on the AIM65, but this have started some thoughts about making a RAM-disk I/O system, based on a ARDUINO (mega) and a pair of SD-card readers. The Arduino programming in C is not a problem, and using AIM65 I/O-system for tape, it would be minimum change in the AIM65 monitorsystem, to use such a system for input and output via the tape-function in AIM65.
NOW...
I wonder, if any other eksperimentator here in this FORUM, ever had thoughts about such a system?
OR...
If any other eksperimentator here in this FORUM, would like to works with me on such a SD-card read/write system, to replace a tape recorder-based system on any 6502 vintage computer?
