I have about three apple service repair guides on these I haven’t uploaded yet. I uploaded a much older service guide here (you'll want to look at pages (1.17-1.18). Other than that guide I have September 1993 - November of 1995 covered if you need that information like I said just haven't...

Sounds like to me cap goo may be under your sound chip I would advise removing it and cleaning under it or if you do not feel comfortable doing that really try and clean that area with alcohol. Another thing that could be causing the chimes of death would be a a bad RAM chip it's very common, oh...

Woke up today wondering why I had a $65 charge on my card from Digikey-Key, I didn’t order anything. I go back and look at my orders turns out I placed an order in January 2021 and it just shipped that’s how bad chips have been backordered….wow.

Big update! I found the missing manuals albeit this is the April 1990 set. These include “100 Macintosh Service Course Prerequisite Manual Volume 1”, “100 Macintosh Service Course Prerequisite Manual Volume 2”, “100 Macintosh Service Course Lab Manual”, “203 Laser Printers Service Course Pre...

I found this on eBay by chance and bought it within 20 seconds of it being listed. I’m happy it’s now preserved. Unfortunately one of the binders were damaged in shipping (ring broke off binder backing). The pages were perfectly intact and undamaged so all I did was swap everything into a new...

Out of curiosity where did you happen to find a prototype IICX?

It’s so nice when it’s a simple fix.

Hey Jake from the future here check that your power cord is actually plugged in. (wow what a night)

Hey everyone I have an Astec AA 1104B Apple II Power Supply, When I got the Apple II it came from I plugged it in and at first only the power light would turn on followed by the breaker for three rooms in my house popping. So I did what any other Apple II owner would do when presented with such...

Gotcha I’ll get a list tonight

I would be all for making these kits, I can try and make a batch. If you do plan on using this method with a III it’ll work fine but if you use a III Plus you will need to adapt it to a DB19 connector. I suppose you could just use the internal connector on a iii plus bit then you will not be...

No School Like The Old School (Literally), Enjoying the Bell and Howell!

Hey if you want me to ship my prototype for you to tinker with I don't mind letting you borrow it and see what you can share from it too. I don't know much about it or how it works.

Absolutely, sorry some monitors may be vague such as the smaller CRT's like the ColorPlus 14"

Not sure if I'm any help here but I recently just read the ROM from a Lapis II Dual Page. The chip used was a 27C64A I also included this ROM below, let me know if it helps, if not at least its up.

I was actually going to take a whack at trying to recreate these too was planning on starting later today.

And once again I completely missed the fact this was a two ROM board I thought it was a four and overlooked it, @marcelv youre correct.

My apologies I was wrong was looking at it going right to left but if one were to go from left to right (which is the way it’s supposed to beit would be the following: LL-341-0864 ML-341-0865 MH-341-0866 HH-341-0867 hence ROMs are in proper order
