I haven't played with MFM hard drives and controllers in a LONG time
(about 10 years now) so I have some questions.
I'll start off easy. Should there be any reason an old 16-bit ISA MFM
controller won't work properly in a Pentium-class PC with ISA and PCI
slots? I imagine I would just have to configure the BIOS to reserve the
proper interrupt (I believe it's 14, correct?) for the MFM controller.
I did all this but the MFM controller wreaked havoc on the system. It
killed the on-board floppy disk and IDE controllers (not physically killed
but basically disabled them and the system couldn't boot).
I'm trying to determine if there is a natural conflict before I venture
forth with this configuration. This may be a problem related to the PC
I'm trying to plug the card into because there are other oddities with the
IDE controller that is preventing the system from booting with 4 hard
drives installed (2 per IDE interface). It halts after it auto-recognizes
the drives on the primary controller. Weird.
Anyway, any insight would be appreciated.
I'm going to do more experimentation in the meantime. I'll get another PC
with ISA and PCI slots to work with, and will also find an old 386 to test
the MFM controller on to make sure it is working fine.

I'm seeking out for a friend the game Gods for the Amiga. I'd like to get
the full original package with all the trimmings preferably.
Has anyone got a copy of this that they'd like to sell?

Actually, to nitpick, dry cells at least are properly measured under a
light load, because as they age, they develop higher internal
resistance. Measuring them with a high impedance voltmeter will
suggest they're good when they're not.

Greetings:
In attempting to salvage some files from an HPIB
drive which is ailing, I installed RMB Kermit to
do serial xfers (long files > LIF floppy capacity)
however it needs Basic 6.x and we've got 4.0.
Would a kind soul please send us the 6.0 system file
(it can be converted to an MSDOS file using the
'lifutil' utility (use Binary/DFS mode) so we
can fire up kermit and rescue the data before
the drive dies?
('lifutil.exe' is available at ftp://ftp.cybertheque.org/pub/lifutils)
All help much appreciated.

What's a good online resource to figure out what type of memory chips you have?
I have an old matrox Ultima + VLB card that has 2mb vram (consisting of 8 x KM428C25J-6 chips) and has 8 more sockets for 2mb more memory (the type where the chip pins are curled around and point to the bottom of the chip)
Are these common chips? Most video cards I have seen either use dram or edo ram.
Anyone know whatever happened to Chris Johnson? I sent off for an HP-85
>from him (back in late September last year), & still haven't recieved it!

We have some here, 2 * BY1144 triode, class B, 250KW carrier,
and TH538 tetrode, single ended, 300KW carrier. The filaments
alone on the BY1144s take 5KW.
