Want to burn Vulcan 2.0 (Gold) Rom. What equipment do I need?

What type of EPROM does it use?  I've got a Minipro TL866CS programmer which was fairly inexpensive (under $75 including a large assortment of chip adapters).  I've been able to program most of the common types of EPROM used on Apple II cards like 2716, 2732, 2764, 27512, etc.  You might also need a UV eraser (mine was under $25).  I bought both my programmer and eraser on Aliexpress, but you can also find them on Amazon, eBay, etc.

Most 2716 and 2732 need a program pulse of 25V. This chinese programmer can just generate 21V. Means these EPROMs burnt with a low voltage pulse are not reliable.

And there is another issue with this programmer: the data base is often faulty, especially with the old EPROM types.

I've heard a lot of people say this, but I've not had any troubles.  I have the older version not the -II version.  Some people say the new version won't do some of the chips the older version can.   I've also heard that later firmware versions broke some things.  I only did one firmware update necessary to get the Open Source software that I use under Linux to work.  I don't have Windows, so I can't say how well the supplied software works or how accurate it's database is.  It does appear to work under Wine and other people have reported it to work, but I'd rather just use the Open Source code, as it has worked well for me.

The EPROMs I've programmed have been a mix of old stock I've had in my parts bin for 30+ years as well as newly purchased parts from Aliexpress.  I've yet to have a failure and the chips I've programmed seem to work reliably.

Anyway, there are other choices, but almost all of them are significantly more expensive.

Thanks RalfK,

From this thread https://www.applefritter.com/content/apple-ii-plus-iie-vulcan-drive-no-info-any-help it appears that one communitity member believes it to be a  27128...  I know nothing.   Is this doable by me if I purchase the right equipment?  I still don't know what will work, only have your hints on what probably won't.

Anyone offering eprom burning services out there?  I'd really love to get this old Vulcan using a 100MB (or larger?) compact flash.

Thanks,

Bill

I don't believe I've done a 27128, but I've done most of the other common sizes.

I can do it. Do you have the code?

PM me with the code & I'll let you know if it fits on a 27128 or whatever.

My Vulcan EPROMs are all 27128s

16k

All the Vulcan dump files are 16 Ko, 27128 EPROM size.

The Gold GS ROM 2.0 is available here.

For got to mention, for some time there's a guy on ebay that's been selling kits  to upgrade the Vulcan. It has the EPROM, CF, adapter and a utilities floppy

The Vulcan gold uses a different partition manager. I'm sure I've seen it online but can't recall where.

Send me an address and I'll email it to you
