OK, so I understand that there are "standard" //e computers and "enhanced" //e computers. The latter have 65C02 processors and upgraded ROMs and video that add a variety of nice feature, the one of which I like the best is being able to type lower case BASIC commands.
The "junk" //e I have is a beige numeric-keypad version. The motherboard has two 64x4 RAM chips. It has the enhancements.
The nicer //e I received today (stuffed with interesting cards, although the seller had rendered it unbootable by placing the Transwarp card in slot #3 and also installing the Apple 80 column card. The boot display was...interesting...fortunately having boned up on old manuals in the last few days I recognized the problem...) has an older motherboard with 8 RAM chips and does not have the enhancement upgrade.
Now, if I wanted to enhance this machine, I see two choices:
1. Bid on the NOS enhancement kit somebody's selling on eBay now. Starting bid is $75
2. Pay vintagecomputermuseum $79.99 for a guaranteed working //e motherboard of the two-RAM-chip type.
So, my question is: are all two-RAM-chip motherboards enhanced? Looking at the photos of the motherboards for sale I see most of them are using 6503 chips...
