After getting the #Commodore#C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain. #floppydrive#retrocomputer
Today's project is re-writing Catalina for 8-bit support, but I'm having issues getting logging in to work. Or actually anything at all. Honestly this is just fever dreaming isn't it. Am I real?
The 128D is real, though, and one of the better looking Commodore 8-bit machines.
Tested the power supplies, including the one that I already owned.
Only the #C128#PSU has 5V in spec, at 5.02 Volt.
The #C64 PSUs have 5.18, 5.24, and 5.43 Volt - first value is concerning, latter two are dangerous. I'll have to open them and try to fix them. #commodore#retrocomputing#repair
A latency-hating emulator of 8- and 16-bit platforms: the Acorn Electron, Amstrad CPC, Apple II/II+/IIe and early Macintosh, Atari 2600 and ST, ColecoVision, Enterprise 64/128, Commodore Vic-20 and Amiga, MSX 1/2, Oric 1/Atmos, early PC compatibles, Sega Master System, Sinclair ZX80/81 and ZX Spectrum....
I'm trying to play with SH4 CPUs in a few set-top boxes I have. This is difficult as the whole STLinux FTP server is long gone.
If you, or anyone you know has these files:
Hmm. I wonder if I poke random values into RAM if I can crash my RC2014? Let's find out! I'm sure someone can tell me but worst case I reboot so let me try it lol
@anniethebruce yeah...
Basically it's been turned into some commercial product.
Amd whilst they can't opensource or share the BASIC & KERNAL they could at least not go out of theor way to prevent others from iterating upon it and buy that ROM through them legitimately.
The #CommanderX16 / #X16 thus is more a toy for #C64 & #C128 fans that want something they can easily hook up to a modern TV.
THE #RC2014 in comparison looks like an open architecture.beyond the ability to make expansion cards.
@breadbin and I are trying to get a ten-unit group buy together for Commodore 1581 clone PCBs. We need enough people to cover eight more of the order of ten PCBs, at $10 per PCB plus whatever shipping ends up costing from my local post office once they arrive.
These are unpopulated PCBs, they probably won't cost a fortune to ship one or two at a time, to be clear.
I have no need to make a profit from this, this is just a couple dudes looking to save some coin.
WinVICE is a program that executes programs intended for the old 8-bit computers. The current version emulates the C64, the C128, the VIC20, all the PET models (except the SuperPET 9000, which is out of line anyway), the PLUS4 and the CBM-II (aka C610)....
@gruber Windows 11 on Parallels on Apple Silicon isn’t just good, I find it much snappier, smoother, power-efficient, and generally robust than Parallels on Intel Silicon Macs ever was. Even when running ancient x86 software, like an old version of QuickBooks I’m embarrassed to say I still use. Intellectually, I understand the appeal of removing virtualization from the picture, but getting quick access to Windows apps while I’m still in MacOS is so nice I’m already very happy.
But my recollection at the time was that the #Commodore128 could never be another world-beater like the #Commodore64. #IBM#PC clones cost the same or cheaper for business, it wasn’t much better for #gaming than the #C64 compared to the new 16/32-bit systems like the #Amiga and #AtariST.
The #C128 mainly appealed to heavily-invested 64 owners who were also willing to (re-)buy the few released software titles that took advantage of 128 mode.
