I have a 6100/66 that I am trying to get software on. When I burn a CD on a modern Mac, using an LG DVD/CD burner reading the CD on the 6100 causes the system to freeze. Is there a workable hardware/software setup to be able to do this? Am I pursuing the most efficient method for transfer of...

I'm trying to load the PS2 onto an Icom Attache with a turnkey and ACR boards. The Turnkey board has the UBMON and MBL roms. It seems like entering the bootloader in the PS2 manual is unnecessary given it's on the MBL, but when I try to load with the MBL at 177000, at the end of the load it...

I thought I'd give the forum a shout to see if by some stretch of luck someone may have a spare. My system is only missing the transformer, which was removed by a previous owner. Otherwise, I plan to convert the PSU to switching supply units. I suppose I could cannibalize a "spare" Northstar...

Recently I acquired an IMSAI. Aside from the front panel, CPA-R4, there were no boards. My initial goal is to have it run extended Basic via the M Eberhard 88 2SIO-JP, with BASIC rom mounted. Seems simple enough. MITS Ext Basic requires 11k of RAM. Out of the several RAM boards that I have...

Since the Altair doesn't have an internal 5/12v pigtail like, for instance, a Northstar Horizon has, what would be the best approach in supplying power for an external, non self powered Shugart floppy drive? Tap it from points in the Altair PSU or supply externally, say from 2 wallwarts (into a...

I have an 81-292 ROM, Kaypro II from about '84. I have installed a Gotek into the drive A bay and am able to boot and load "disks" that way. However there are a great many programs that are not disk images that I would like to transfer via serial, such as .com or .bas files, since those are not...

👋I could use some help troubleshooting a problem where no matter which address I examine, the data lights all remain on, even after a hard reset and entering data into any address. 🎦 Just a ballpark guess makes me suspect the gating logic on the CPU board, ICs O and R or IC X, 8T97 is stuck...

Was getting close to normal function, with a Solos prompt and simple operation. Was having some I/O issues, unable to talk to the port externally, or launch the Terminal. Suddenly, after testing voltages on the Personality module and power cycling, I no longer have a prompt or ability to enter...

I'm attempting transmit programs from my laptop and my SOL-20. Of course there is guidance in the user manual as far as setting an input port, reading and executing, but I can't seem to find much in terms of guidance on how to configure the source computer side. I have tried Cool Term amongst...

I need some help with a SOL I recently found. I have experience troubleshooting vintage electronics, such as radios and TVs, but computers are new territory for me. I've tested the PSU via the Molex connectors, as described in the original literature and all the voltages are dead on, however...
