8BitsNoneTheRicher Posted December 8, 2022 Share Posted December 8, 2022 I'd been looking for one of these machines for years, and finally found one that checked all the boxes: Sorcerer II, 48k RAM, everything works, non-insane price--and I got it in its original box! I also found someone willing to sell me their spare BASIC ROM-Pac, which also works! I need to open the machine up and start replacing capacitors, but for now I think I'll just putter around with it for a couple of days. 17 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/ Share on other sites More sharing options...
Arnuphis Posted December 9, 2022 Share Posted December 9, 2022 It's great when you land something you have hunted for over the years. Never seen one of these in the flesh.

fiddlepaddle Posted December 9, 2022 Share Posted December 9, 2022 Me and a buddy co-wrote a video game for one of these in our spare time after school at a local computer store right after the machine came out, and sold a few copies through the display case at the computer store. 6 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/#findComment-5168682 Share on other sites More sharing options...

The S-100 capabilities we really advanced though, and the built-in parallel and serial ports were unheard of at that time. 1 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/#findComment-5169035 Share on other sites More sharing options...
Krebizfan Posted December 9, 2022 Share Posted December 9, 2022 The Microbee has a lot in common with the Sorcerer. The Australian Dreamdisk controller works on both systems. Some software works on both. I don't know how hard it would be to convert other add-ons to the Microbee into ones for the Sorcerer. 1 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/#findComment-5169172 Share on other sites More sharing options...

I read a writeup someone did on an unearthed Sorcerer where the machine ran for a few seconds after not being powered up for years and one of the filter caps blew up. Made me a bit nervous. As rare as this thing is, I would prefer not to take my chances!

wierd_w Posted December 20, 2022 Share Posted December 20, 2022 Sad. Those are running between 60 and 120$ retail, with low inventory availability. It would be cheaper by far to add a 3<->5v dc-dc converter and a level shifter to a teensy 4.

jltursan Posted December 21, 2022 Share Posted December 21, 2022 Yep, probably easier than migrate the code. I've never programmed these kind of devices but seems that between Teensy and STM there're quite some differences.

ClausB Posted December 23, 2022 Share Posted December 23, 2022 Teensy is programmed with extended Arduino libraries. Install Teensyduino on top of the Arduino IDE. Also install the SDFAT library.

8BitsNoneTheRicher Posted December 25, 2022 Author Share Posted December 25, 2022 Hey all, of course I meant "Teensy" and not "Teeny." Thanks, autocorrect. I've now sourced all the caps I needed for the power supply board and will start on that project when I get back from my holiday. After that I will look into options for some kind of SD "disk" for the Sorcerer. Speaking of microcontrollers and such, I've been a little distracted with my new "MisterFPGA" rig! Great fun. Hopefully someone creates a Sorcerer core for it.

jltursan Posted December 27, 2022 Share Posted December 27, 2022 Now you mention it, I don't know of any FPGA implementation of the Sorcerer. Seems a simple architecture; but who knows... The only "massive" storage solutions I know for the Sorcerer are the ClausB's Teensy-based tape reader and the uIDE; but this last one is only a possibility as it need to be paired with a complete set of drivers to be operative, and there're none right now.

8BitsNoneTheRicher Posted January 9, 2023 Author Share Posted January 9, 2023 I've now completed the re-cap of the power supply board. The 1500uF cap was bulging pretty badly, probably cooked from being fairly close to a large 5W resistor on the board. Now that I'm sure it won't blow up, I've been playing with it quite a lot. I also managed to locate at Teensy 3.5 board, which I probably overpaid for at about $65 but options were few. Now to figure out how to configure the Teensy. Soldering it in looks super simple--only 4 pins soldered to the Sorcerer's UART. Wish me luck! 2 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/#findComment-5187347 Share on other sites More sharing options...

Be sure to bend those UART pins out slightly so they don't go in the socket. That keeps them from connecting to the existing cassette circuit.

8BitsNoneTheRicher Posted January 12, 2023 Author Share Posted January 12, 2023 Hi Claus, thank you for commenting. I recognize you as the creator of this marvelous bit of tech for our ancient Sorcerers. Amazing work! I have a couple of small questions regarding getting the Arduino and Z-80 code onto the Teensy. I can PM you if you don't mind. With your permission I might document the whole process for the other 3 people worldwide that are Exidy Sorcerer owners. I saw your advice to another user regarding pulling out those UART pins. I also saw that he'd had some clearance problems under his power supply board which led to him soldering the Teensy leads to the UART. After thinking it over, I'd prefer NOT to solder to that chip so I am buying some very low-profile clip leads which hopefully will eliminate that problem. 1 Quote Link to comment https://forums.atariage.com/topic/344733-after-years-of-searchingi-now-own-an-exidy-sorcerer/#findComment-5189268 Share on other sites More sharing options...
