Working - Radio Shack TRS-80 Mini Disk for Model I - 26-1161 - Shugart - Rare:
This sale is for a working Radio Shack Mini Disk floppy drive unit for use with a Radio Shack TRS-80 Model I. This is an early model 35-track Shugart drive (Oct 1978 - stamped on power supply - have to remove screws to see it). Notice the 2-prong power cord and the reverse color label (still has protective plastic covering the label). Finding Shugart drives in general is difficult. Finding one in working condition is very scarce. Common problems with these drives were that they tended to get out of alignment so would no longer read diskettes or door hinges would break when slightly too much force was used to close the door. This drive has neither of these problems.
Only the drive unit, pictured boot diskettes and terminating resistor are included. Door hinges are intact and not broken. Cosmetically the unit has light scratches overall the entire case and a number of deeper scrapes, chips and scratches (see pictures). Drive is not terminated so intended to be used with another terminated drive which would be farthest from the computer (e.g., drive 1, 2, or 3). However, I'm including a terminating resistor that could be installed in the drive and then the drive could be used by itself.
I have a working copy of an alignment diskette. Alignment of this drive was adjusted as was the read sensitivity. After drive was adjusted, the drive went through testing.
TESTING:The drive works great. I ran TEST2/BAS over 25 times without any errors detected even with diskettes not formatted on this drive (if out of alignment a diskette formatted on the drive will pass but other diskettes will not). These old drives run hot and this one is no exception and is entirely normal. This drive read every diskette I put in the drive (all diskettes were known to be good). TRSDOS 2.3 only uses a single side and only uses 35 tracks. This drive is a 35 track Shugart drive so can only be used with a Model I. Write protection was also tested and was successful.
The included diskettes were made on this drive by doing a single drive copy of my working original TRSDOS 2.3 diskette from the 1980's. Drive read the ancient diskette flawlessly. The second copy was made by copying the first copy to verify all was good.
I do not accept returns. I will combine shipping. Please ask if you have any questions. Payment is expected within 3 days of the close of the sale (if immediate payment is not required). Payment is via PayPal. I do not ship outside the United States. Shipping cost is for lower 48. For Alaska or Hawaii please ask. Thanks for looking.
