Need help with Macintosh Techstep Project 

 

Hello I am working on a project for the Apple Techstep and I am looking to buy one of each type of ROM Pack for the unit . I need one of packs that use the 27C512 ROM (SCSI HD Test or CPU Test Vol. 1) and one which use the 27C1000 ROM (CPU Test Vol. 2, Vol. 3, or Vol. 4). If anyone has any extras of these and are willing to sell one of each to me, please PM me with a reasonable price.  I have dumped the ROMs for these and aquired some parts for prototyping making a  ROM cart for them that supports all five ROMs on a single cartridge. 

 

Thanks in advance. 

 

Jay

Jay,

Jay,

 

You said you made a ROM dump of all the ROMs, yet you still need all the ROMs?  Or are you saying you have all the ROMs but need different versions of them with the 27C1000?

 

I just released my TechStep video on YouTube if you want to check that out here:

"Sacrifice" implies "destroy." But why?

Did you ever get anywhere on this project? I've had my TechStep for years, and not done much with it. - Alex

The simple answer to your question is NO.

As you can see, my last post in this thread was made on Nov. 17, 2019 where I asked jwg1962 one final question.  He never answered, and I've not been back to this thread until an email notification alerted me to your post today.

It would be great if something further could be done.
