Would this happen to be the _same_ carrier that the Epson folks used for
ROMs in the PX-8? If so, you might be able to sell some to PX-8 folks
that want to make their own ROMs.

Kool. I meandered over to Motorola's website last nite, and tho they did
not have the datasheets for these chips on the Web, they were available
thru their faxback system... so I have the datasheets IMTLF (in my tight
little fists) right now. I'm leaving it up to you what I scan in... I'm
definately scanning in the pinout w/information, but do y'all want me to:
1) scan in the programming timing information?
2) scan in the fast programming algorithm?
3) scan in anything else?
Oh, and tho the chips have a "C" on them (as in MCM68764C) the datasheets
say they're N-channel MOS. Unmarked speed chips are 450ns access, but there
are some 350ns parts available as well.
Anyway, expect to see some info on this arrive over the weekend on my
website... as it looks like I may actually have 4 or 5 seconds this weekend
to work on it!
for my geezer computer page. (it's small, it's lame, but it's mine! ;-)

I should've posted his e-mail address for replies. Sorry.
He's at Mikeooo1(a)aol.com. Talk to him directly about working out a bulk
deal. I'm sure he'd be happy to work something out. I have no

Thank you! It all worked, and I now have the necessary files unZIPped onto
Now the next hurdle; Ever since I installed OpenVMS 6.2, my second TK50
has disappeared. The device scan, at initial boot, won't even detect it.
Hardware setup is:
KA630 CPU, v. 1.3 firmware
16 MB memory
M3104 8-port serial MUX
DELQA Ethernet card (M7516YA)
RQDX3 (M7555), two RD54's and an RX50
Two TK50 drives/controllers (M7546)
RRD40 CD-ROM controller (M7552)
The Really Odd Thing is that it worked before, under MicroVMS 4.6, but now
it won't even work with that. I suspect, though I've not confirmed it yet,
that it may have to do with:
1). The fact that I've added a CD-ROM controller (appears as DUB0:)...
2). The order that I've got boards plugged into the backplane (BA123 box).
Tonight, I will try transposing the positions of the two TK50 controllers
I have. I will also try jumpering the suspect controller as the primary and
removing the RRD40's board.
Any suggestions would be welcome. As mentioned, I find it interesting that
two TK50's worked under MicroVMS 4.6, then suddenly stopped working under 6.2.
Do I need to use SYSGEN, perhaps, after the fact? If so, what string do I
feed it? (low on docs again!)
For comparison/test purposes, I'm going to CC this to the CLASSICCMP
mailing list as well as your return address. Whichever one you see first
will tell me if there really is a problem with the mail system.
CLASSICCMP users, my apologies. Please bear with me until I can figure out
what's been going weird with mail to Tim's site.
Thanks in advance!
