Re: Unitron EPROM writer?

Hi Mark,

Good advice!  I thought about trying this the other night -- after I had put
away the machines with convenient slot access!  Well, I tried again tonight
in a IIe that I have.  The card wasn't getting recognized in slots 3, 4, or
7.  Then I hit paydirt in slot 2!  I think it has to do with whether I had
the card turned on or off during bootup (yeah, the card has an on-off
toggle!  Crazy).  I think I need to flick the card on while the machine is
booting - if I leave the card in the "on" position before booting, it
doesn't actually come on.  If I want too long to turn it on, it doesn't get
recognized.

Anyway, when I do pr #2 and get into the software, all I get is a very
simple screen (but hey, at least it's a screen!!).  It says:

EPROM WRITER USE PR#1-PR#7 ROM SIZE:
2708=1 2716=2 2732=4 2764=8
ROM SIZE?

If I hit "?", I get a little menu:
    1) WRITE
    2) READ
    3) COPY
    4) MON

Hitting 4 drops me into the monitor.  I haven't played too much with the
other options, but they seem to be very particular about the memory regions
that you are interested in reading/writing/copying.

I think that the four sets of numbers refer to 4 empty sockets on the board,
numbered "08", "16", "32", and "64".  They are 14 pin sockets, but are quite
distinct from the large EPROM socket (which has an open/shut lever, kind of
like a ZIF socket on a PC motherboard).  There are other populared 14 pin
sockets, but I don't think they are related to these empty ones - I can
transcribe their markings, if that sounds interesting.

Anyway... I don't know if you (or anybody else) has used an EPROM burner
before, but does this sound kind of like a normal type of interface?

Thanks!
