Sorry, but you've got your head stuck in the 60's.  Those old 
TLD1100, TLD1470 type transceivers were huge.

The first generation of the Pulsar transceiver looks just like a 
Mocom 70 and measures 13 3/8" D. x 10 3/8" W x 4" H.  Substantially 
smaller than a Micor at 17 1/2" D. x 13" W. x 3 3/8" H.

The second generation Pulsar transceiver, introduced at the same 
time as the Pulsar II head, is a much better box and is unique in 
appearance [as compared to any other Motorola transceiver package].  
These are about the same size as a Micor at 17 1/4" D. x 12 1/4" W. 
x 4 5/8" D.  These weigh 30 lbs. vs. the Micor at 25 lbs.

The first generation transceiver was a case of too soon, too far and 
had a poor reliability track record. We always thought that was why 
they changed the appearance of the product to make sure there was no 
association with the earlier units.  Accordingly, the second 
generation transceivers are the most desireable for use in repeater 
projects.

The VHF Micor has a rated receive sensitivity of 0.50 uv. for 20 dBq 
whereas the second generation Pulsar drawer is rated at 0.55 uv for 
20 dBq [at the antenna port through the duplex filter] with no more 
than 0.05 degradation when the transmitter is activated.

After the Pulsar II head came the Pulsar 100 and 120 models which 
offered less features at a lower price.
