    The 800 RAMDisks don't use PORTB (it's too busy controlling the other two joysticks for MULE).

    I guess so... looking at the source reveals it's using $D701 as the control register to switch banks, learn something new everyday :)

    10    *=$B86
11  LDX #0
12    *=$B88
13  CMP #7 ;DRIVE #7
14  .BYTE $B0,$47
16    *=$105C
17  LDA #$64 ;$64=100
18    *=$105E
19  CPY #7 ;DRIVE #7
20  BCS $1076
22    *=$12DE
23  JSR $12ED ;LOAD Y FROM ADR.$21= GET DRIVE #
24    *=$12ED
25  LDY $21 ;  LOAD Y FROM ADR.$21= GET DRIVE #
26  CPY #8 ;  SEE IF DRIVE #8
28  BCC *+4 ;  IF NOT JMP TAY
30  ADC #5
32  TAY
34  LDA $185B,Y ;  GET BANK # FRON TABLE IN 185B
36  JMP $1846 ;  DO BANK SWITCH
38  RTS ; RETURN ?
40    *=$148D
41  CMP #6
42    *=$14C4
43  LDA #$70
44  JSR $1846
46    *=$183A
47  .BYTE "MEM.SAV ERR",$9B
48    *=$1846
49  STA $44 ;STORE BANK #
50  LDA $D0 ;$D0=0 1st TIME
52  AND #$00
54  ORA $44 ;ORA W/# IN $44=BANK #
56  STA $D701 ;CHNG BANK #
58  STA $D0 ;NEW BANK #
60  RTS
62    *=$185B
63  .BYTE $01,$02,$03,$04
64  .BYTE $05,$06,$07,$08
66  .BYTE $09,$0A,$0B,$0C ; TABLE  OF BANKS = 12 FOR 800+
68    *=$70A
69  .BYTE $C3
70    *=$77F
71  CPX #7 ;DRIVE #7
72  BCC $78A ;78A OR 7BA ?

    So it's possible to have a conflict with other devices :-o

    If you have an IDE+2, be careful of these files. I booted these with the IDE+2 attached (holding down SHIFT, I think) and by doing that, it clobbered the HD partition. I had to set the HD up completely from scratch, partitioning and everything. I'm not sure what happened, but it was working perfectly before I booted, then nothing. Yes, I know they are for an 800, but I wanted to see how it behaved, loading into an XL. Now I know... :_(

    I don't think the RamDisk mod would affect the $D5xx control register area that might cause that condition. Ram Disks just use PORTB for the bank selection.

     

    What version(s) of the IDE+2 do you have?

    You can get these for $150 normally, I'd never buy from this seller because he lies about what he sells and always over prices what he sells...

     

    Case in point:

    He bought a RM-1000 radio modem for a best offer of $100 after he saw that I paid $70 for one last year.

    He relisted it for $275 eBay Auction -- Item Number: 2735161908641?ff3=2&pub=5574883395&toolid=10001&campid=5336500554&customid=&item=273516190864&mpt=[CACHEBUSTER] and stated:

     


    Powers on and I got a handshake from the port so should be working.

     

    So I asked him what kind of "handshake" did he get, his response was:

     


    Hello, "handshake" is an old term for the initial communication between computers. For instance, Computer sends a high signal sent on RTS (Request to Send) pin. It is responded low by the receiving machine on the DTR (Data Terminal Ready) pin. this happens a few times and the up down up down exchange is called a handshake. I sent a signal with an digital oscilloscope. Might fiddle with the modem more this weekend but no cb is going to be an issue.

     

    This Radio Modem doesn't have those signals on any of the connectors, plus it doesn't work that way...

     

    I reported it as a fraudulent listing :)

     

    He revised the description now: eBay Auction -- Item Number: 2832859880651?ff3=2&pub=5574883395&toolid=10001&campid=5336500554&customid=&item=283285988065&mpt=[CACHEBUSTER]

    It has a race condition with certain applications. LibreOffice is one of them.

     

    Try starting it before whatever is colliding with it.

    Yeah, some programs use their own message que and conflict with others when inappropriately handled. I don't use the "Broadcast to All" window handle when setting the font and other dialog messages.

    I'll add a custom SendMessage() routine to try to catch and resolve...

    Thanks for all of the kind sentiments guys, it's really appreciated :) :thumbsup: :thumbsup: :thumbsup:

     

    Tuesday I met one of the eye surgeons and talked about the procedure and recovery and today I met two of the RN's that will be assisting. Everything is all ready and set for next Thursday :thumbsup: :thumbsup: :thumbsup:

    I can't wait to have 20/20 vision again :)

    I only wish that I had known sooner than 2010 that Best Electronics had 1450XL mobo's for sale. Thankfully mimo came to the rescue and sold me his. It wasn't until 2010 that I brought out my 800 and 810's from storage after a 15 year sleep...

     

    I'm sure he regrets selling it as there hasn't been anymore showing up on ebay or in the wild since then...
