Loaded at 300 baud and works - so, Paul - I think your 300 baud Chomp may be corrupted.

Nice! I'll put checking the chomp file on my backlist... :roll:

Did you know about / try the sound mod on the parallel port? Attach a small speaker on pins 1 and 4 of the parallel port and you'll have audio support.

It is obviously a made up name. Don't you think?

Whilst waiting for some 18 pin DIL sockets to arrive, I thought I'd renew some of the tantalum capacitors; in particular the two that had gone closed circuit. Previous tests, obviously, were carried out without these in place. ...
Sorry to resurrect this. I was wondering how you found the shorted tants. Or did you find out that two had shorted after they were all removed?

Would the approach: “cut the tantalum legs until the machine boots” work? Obviously with the risk that the last one to cut was the shorting one.

The reason I’m asking is a Sorcerer in a Dutch museum that seems to have the same symptoms as yours had, but the repair attempt seems to have reached a dead end. See the link on vced here:http://www.vcfed.org/forum/showthread.p ... erer-error

Hi DA

I replied on VCF. The only way to fix it is to pull tants on the affected rail one at a time until the rail voltage is restored. Also, per my previous posts, replace tants around the memory if there are corruption issues. Actually I'd replace them all, just to be on the safe side (which i am pretty sure is what I did to my Sorcerer).

...This time we have an Exidy Sorcerer, which fell into my lap totally unexpectedly from its previous owner who'd had it from new. It's equipped with a Liveport FDM 180 hard sectored disk drive and should boot into CP/M. ...
Strictly speaking, it is not the drive that is hard sectored but the controller (and the media). For my hard sectored controller I could happily use a 40T drive that I also use for a BBC. I don't know if you tried this, but to isolate the fault to the controller you could try with another 40T disk drive.

Hi Paul

You're right, I think, except that on some drives it's necessary to set a jumper for hard sectored operation - the Shugart 850 is an example.

At this time, it is evident that the boot ROM that lives in the drive unit is not being accessed properly by the Sorcerer. The two are connected with a 50 way ribbon cable and I've checked it for continuity (it's OK).

But the Sorcerer is away at the moment while I sort out some other projects.

Cheers
JonB
