I've sent this to the list about an hour or so ago, but it hasn't arrived. Sorry if it' sent twice...
-------- Original Message -------- Asunto: Original Apple //c (ID byte #FF) upgrades Fecha: Thu, 12 Jun 2003 12:55:27 +0200 De: Antonio Rodr�guez <[EMAIL PROTECTED]> A: Apple2list <[EMAIL PROTECTED]> Hi! I have been also without receiving mail from the Apple ][ List from May 20th, but I thought it was common in this list... I suscribed that same day, and because they say "wherever you go, do what you see" (old Spanish saying) I waited to see what was happening... Ok. Now for the questions. I have an original *unmodified* Apple //c, with the original ROM and motherboard - yes, the ones with the modem port bug and without 3.5" disk support. And I would like to upgrade it to revision 1, in order to have the Mini-Assembler in ROM and, possibly, being able to get a 3.5" external disk drive to exchange files with PCs via the Macintosh Classic I own ;-) . The serial port bug isn't a concern for me, because I only use it to connect the //c to one of my PCs in order to transfer disk images (or to use the PC as a terminal for ProDOS! :-) ), and it works without problem at 19200 bps. I know the Mini-Assembler upgrade would involve installing the new 32 Kb ROM/EPROM of the Apple //c revision 1. But my model only has 16 Kb of ROM. Somewhere I have read that you should cut and solder some solder points in an original //c motherboard in order to make it work with a 32 Kb ROM. Is it right? Do you have more information? And, where can I get a 32 Kb ROM image so I can burn it in a EPROM chip? I think a 27256 should work for it... I'm not sure if the ROM upgrade would fix also the 3.5" drive support. Is the new drive supported by a SmartPort driver located in the new ROM, or do I need an updated IWM chip? In the case of being the SmartPort driver, what ProDOS version do I need to download to the Apple //c in order for it to support SmartPort devices? In 5.25" disks I only have ProDOS 1.1.1, the version that came with my Apple //c... :-( By the way, I know Apple provided that upgrade (from revision 0 to revision 1) for free, but that was almost 20 years ago, so I think I'm not going to ask for it in an Apple dealer ;-) . One last question: do you know where can I get blank or used 5.25" DD disks? I've run out of them, and have found that HD ones doesn't work, at in my //e Enhanced's Disk ][ drive.
