I ended up with a small run of @clueless_engineer (Brett) 's 2764 to 2732 EPROM adapter boards (9 left), and I got a smaller bunch of the 2764 EPROMs (4 left); I'd like to share these at my cost+shipping (unpopulated boards were $0.50 and the EPROMs are $5). If you like I can also program the...

Thanks for posting the video on how to use the OZROM for the memory test, I installed the 2764 daughterboard adapter you designed and burned the 1.44v + OZROM image onto the EPROM and it worked, both modes, perfectly. I'll need to design a switch to mount on the front case to switch between...

Mangled the link on the previous post, trying again: http://cpmarchives.classiccmp.org//cpm/Software/WizardofOsz/OCC1-141.zip Also attaching the ZIP.

Does anyone have a method to convert the IMD (Image Disk) in this file/link (http://cpmarchives.classiccmp.org//cpm/Software/WizardofOsz/OCC1-141.zipformat to HFE for use by the FlashFloppy+? I've tried a few ways but nothing seems to make the resulting file readable on the Osborne 1, I usually get

Thank you @VERAULT the video adapter is definitely a quality of life improvement on my tired old eyes...

I've not been able to find a copy of advwidth mentioned in the documentation, but I did find this at http://cpmarchives.classiccmp.org//ftp.php?b=cpm%2FSoftware%2FWizardofOsz%2FOCC1-141 Now to figure out how to edit the binary...

Chiming in on this old thread, I have a memory of working with a LatinData machine in the mid 1980s in Argentina (Buenos Aires, Florida, Vicente Lopez). My dad ran an accounting/invoicing business that used one of the LatinData computers alongside an Osborne 1. I vaguely remember playing some...

Are the OZROM+1.44a and daughterboard available for sale anywhere/anyone have a spare they'd part with? Seems like a nice upgrade...

After reading that HxCFloppyEmulator has problems converting from IMD to HFE, I tried RichardLoxley's process using disk-analyse (steps to clone the git, build it, install it). When trying to read the resulting HFE file on the GoTek/Osborne it would report that the disk was unformatted. Boo...

My daughter and I were looking to play (and finally finish what I started decades ago) the original Adventure on the Osborne 1. On the bootable floppy disk that came with the Osborne 1 was a copy of ADVENTUR; when running it it presented like I remember, starting you at the End of the Road...

I haven't been able to figure out the PM system here yet (maybe my account is too new?) but I'm interested in one of these if they are available, thanks!

Agreed, I pried off the space bar and found the right side of it is not attached to the stabilizer/equalizer rod under it. Another issue I seem to have is the caps lock isn't working. Anyone know how I should address that one?

Hey folks, just an update... whatever is going on with this power supply is beyond my technical capabilities to solve (even after following Hugo's breakdown), so I ended up buying a Universal Power Kit from ReActive Micro (https://www.reactivemicro.com/product/universal-psu-kit/) and that got...

One of my first computer related memories was from the Osborne 1 - my father bought one for his income tax business that he ran in West Covina, a suburb of Los Angeles in California. I remember sitting with him, typing up basic programs from books and magazines to run on it. He eventually got...

Hi, just wanted to say thank you for sharing the 3d model, a friend of mine with a 3D printer printed the faceplate face down which gave it a perfect molded texture, then printed the brackets and attached them together w/ superglue. It worked perfect. I had to tap out the bottom screw holes to...

I don't disagree with you, Hugo, it is always best to actually determine the fault and work from there. I do feel that unless you're doing lots of repairs on devices of the same type, there is a hard learning curve each time to deeply learn the kit to know what's going on, so try the easy...

Or should I just throw the towel in and get one of these aftermarket power supplies? https://www.reactivemicro.com/product/universal-psu-kit/ Anyone recommend or not on these?

Hi everyone, I'm trying to get old Darth Vader Apple II running again and its power supply is giving me a hard time. No visible signs of life on power up. Took the power supply out, it is an Astec AA11040B. No voltages at any of the pins (+5,-5, +12 or -12) all dead on multimeter. Testing...

Family is from Argentina and I spent some time there as a kid, that's where I first played with a Timex Sinclair 2068. The comic books you could pick up at the corner newstand had short Spectrum ZX Basic program listings, and given the TS2068 is a Sinclair derivative I kinda followed that...

Hey folks, joining the forum to see if I can get some help getting an old "Darth Vader" Apple II working again. My modest collection vintage computers consists of some MacOS X era hardware such as a Ruby G3 iMac, 15" iMac G4, and a beautiful MacPro "trashcan" cylinder. On the UNIX side I've got...
