This is a rare opportunity to own an AIM-65 6502 Floppy Disk Sub System that interfaces to a C1541 or a C1541 SD card emulator that is NOT included. It might be shown in the pictures for reference ONLY! The AH5050 was offered originally by Applied Business Computer Co. Alex Blanco was the designer and owner from my recollection and he offered these through Dynatem once they acquired the rights for the AIM from Rockwell.
The SD card interface is NOT included nor is the SD Card. I will continue testing this setup saving and loading files and report the results as I get more time.I have been working on this design for quite some time now. I made an initial 12 boards of which I have assembled and tested 12 units. These were panelized into 4 devices per board and I manually cut them so that might be a bit crude but in no way affects the operation and size. So please don't make low ball offers for this unique AIM-65 item. This may be late to market but offers a PC based method of file storage and transfer via the Internet. I previously did the same hookup to a C1541 and was able to write and load files so I fully expect this to do the same but I can't say so until I do further testing. I have uploaded 2 pics that show the SD Card directory after getting 2 files from the AIM - the BASIC ROM set and the AH5050-4 ROM. I then changed the contents of that area and printed that out. I then used the Get command and it loaded into that area and original contents were restored.
This was my original testing procedure - write something into the RAM area, PUT it to the SD Card, change the contents of the original area, and then GET the file and see if it matches the original address contents. These plug into the Z1 Application 6522 socket near the rear of the AIM and a working 6522 is plugged in the top of the VEB C1541 board. The 6522 is included and will be tested with the board for the disk drive function ONLY. The connector end plugs into a working Commodore C1541 and the EPROM plugs into the D000 Assembler socket on the AIM.
I did not develop the software so I can not guarantee that it works perfectly but I have been able to FORMAT disks, PUT and GET fiies and print out the directory. The RS-232 interface and the parallel printer interface is NOT on this VEB board so they are NOT included. Besides I expect input from their operation. Maybe some of you will be able to present enhancements or point out bugs with work arounds.
Currently, both the C1541 and the C1541 SD card emulator are configured as Device 1 on the serial bus and I know that won't work. The C1541 has a procedure for making it device 8 or 9 I believe but I'm not certain if the emulator ID can be easily changed.
So if you have one or more we can discuss trade-ins or discounts. I can also swap labor to get your AIM or keyboard working. I have a replacement keyboard in the prototyping stage with switches and a keycap layout that I've sourced to fit these new switches that are not like the original stems but very similar to the Cherry MX switch stem. I can sell those if you want to make your own keyboard. The EPROMs used for the languages - 2532s - might have markings and tarnish on the pins since they are reprogrammed.
