Commodore B500 for Sale of Ebay
by william degnan 04 Sep '17

04 Sep '17

I am setting this: https://youtu.be/zysYRpM7u_o Here: http://www.ebay.com/itm/-/272834135066? I probably don't need to tell anyone this here but the B500 is very a rare machine, the rarest of the B Series computers. I don't know if they actually sold the B500's in stores (US version, not to be confused with the European B-500) before naming them "B128-80". If you buy this also need drives and cables, let me know, I did not include in the auction but I have them too. Pickup welcome. Landenberg, PA Bill

zoomfloppy on WIn 10 computer
by william degnan 04 Sep '17

04 Sep '17

I have a system with Win XT that I had been using a my ZoomFloppy computer, but when the new version came out and it was Win 10 compatible I attempted to install on my PC with Win 10. It worked, but I found that now the X-Cable component of the software suit thinks my CBM 8050 with Jiffy DOS 2.7 is a 8250. It still works but it mis-identified the drive. Also, I have to use D0 only, I can't get it to recognize D1 (the left drive). For me that's ok, but I was wondering if anyone else had similar experiences with their use of the Win 10 Bill

OT: Amazon EC2 Question - Safely reduce EBS Size?
by william degnan 03 Sep '17

03 Sep '17

Please contact me off list with replies. I have a server hosted on Amazon that has 750Gb allocated to it, and I don't need that much space and I'd like to cut it back to cut costs. Whenever I read about EBS they give examples about to increase the size, but I could not find anything about reducing the size. For example here is a page that shows the expand process https://aws.amazon.com/blogs/aws/amazon-ebs-update-new-elastic-volumes-chan… So my question - anyone here ever successfully *reduced* an elastic volume on a production server? Is it a "smart" process that knows to adjust the hard drive volume? How does it work? Does it ask you which partition to shave down, should you unallocate the space first then do the volume reduction, etc? Please contact me off list with replies. Bill

Looking for Help to make a MP/M Disk Image
by william degnan 03 Sep '17

03 Sep '17

Hi, After a lot of effort I repaired a Systems Group 2800 S-100 computer by tracing the electrical faults related to old caps and a 7805 regulator. Now it boots to the hard drive. The system boots up and asks PASSWORD PLEASE- I have tried various passwords but none work. I found a binary of the MP/M OS that came with the SG 2800 here: http://www.cpm.z80.de/binary.html (search page for "Systems Group System 2800") Is there anyone here who can make me a bootable 8" disk by using this binary? In the meantime I am going to see if I can make a generic MP/M disk boot that will work this system, but it would be nice to get the disk the computer came with running. I don't have the skills to use the appropriate assembler, it has been years since Dan Rogantis's class on building a CP/M (MP/M) disk from a binary of the disk files. I suppose I could just copy them to a CP/M disk but I doubt it will boot. If I keep at it I can probably get it to work but I will accept help if this is an easy project for someone else. Suggestions? Thanks Bill
