Q3 & Q8 are the switch circuit for the Neg 5 Volt line. Since only the +5VDC & +12VDC are controlled by the main switch, the -5VDC is controlled electronically. That's why I asked before if R140 & R141 get warm on yours, R141 may need to be changed to 1k? Jay

Thanks HLO, it will make using my Basic XE cart allot more usefull Jay

The schematic from Jerzy Sobola for the 1400 also has same errors with power...

Check out this post for the Atari PDF http://www.atariage.com/forums/index.php?app=forums&module=forums&section=findpost&pid=2371407

The most accurate schematic is the Atari PDF in this thread, but is very unreadable. The one from Best and Jerzy Sobola have the the power inputs wrong and is missing the connections to the 34pin Floppy Board connector, plus U24 has a few different connections... Jay

LOL, I cheated for now and just went with the National MM74HC942N modem... I've got to practice my circuit etching before building the daughtercard, it's been many years since doing that Jay

Can the PBI ID# be changed to another number other than zero (0)? Since the 1450 has ID0 too, there is a conflict between the two... Jay

Many USB ports have a 500mA current limit, ports on powered hubs may also have a similar limit. There are USB Y cables which plug into 2 USB ports, using only the power and ground on one of the ports, which allow devices to draw 1A from 2 of these current limited ports. I have one of these cables that came with an External 2.5" USB HDD. Thanks Bill, I'll give it a try Jay

I have the Top2005+, but so far it only works for reading. Haven't tried using a USB hub with external power yet, which may be the problem?

Good luck with that pos, I managed to burn one eprom successfuly with one of those, destroyed 50 others in the process and spent days trying to sort the bloody thing out. Save your money, either ask someone else to do the job for you or buy something a bit more reliable such as the genius 540 So far I've burned 8 eproms and all worked so far. I did have to switch the voltage jumper and used a 12vdc power adapter instead of USB Power. The one I have was a freebie, so I can't really complain... Jay

Hmmm, after looking at the 3 black case Epyx Pitstop carts that I have, each are different. One has 2 2764's socketed, a Romox case has 2 2764's soldered and the third has a large black blob epoxy covered rom...

I read "STacy" on the other thread and was locked into that and missed the PAK reference in this one The Willem board is also one that I have...

If you have a widows pc with a standard printer port, you can get one of these for $25 and burn your own eBay Auction -- Item Number: 220914295533 If not Sloopy, I can burn them too... Chips can be bought on ebay or Digi-Key. Jay

Does the Stacy use 27C512's or 27C1001's?

Thank you Piotr I received the shipping notice from google checkout for 1 item, hopefully both will be in the same package? Can't wait to play Thanks again, Jay

The inline cable splicing sounds good, I have some shrink tube I can use to make it look clean... Jay

Yep, I see he started a pre-order on 2011-11-25 for the second series of SIDE... Sure would be nice if he'd pop in here and let us know how things are going

Anyone get any updates from Piotr/Zaxon yet? Sure would be nice if Santa brings them for Christmas Jay

Not if I outbid you

Sure, sell it all to me for a steal and I'll make all the Atr's that are needed

Cool, thanks Now just have to see which 130xe to put one in Jay

Oh! okay, I thought you meant email Sure thing, I can do that... Thanks

The original ICD P:R: disk has no dos. On Side A it has: Amodem72.bas Amodem72.doc Autogen72.bas RScope.com RScope.doc Prc.sys Readme.doc Rs232.sys Side B has: Express850.com Express850.doc It would be cool if FW could make an ATR out of these as the disk I have, has many bad sectors. Using the 810 Chip/Archiver, I was able to recover most bad sectors, but can not confirm any bad bytes on those... Jay
